Narrowing your problem to its shortest and purest form is the easiest way to understand it, explain it and fix it. Please test your shortened code to ensure it exhibits the problem.

-// dear imgui: Renderer + Platform Backend for Allegro 5
-// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)
-
-// Implemented features:
-// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
-// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy ALLEGRO_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-// [X] Platform: Clipboard support (from Allegro 5.1.12)
-// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
-// Issues:
-// [ ] Renderer: The renderer is suboptimal as we need to convert vertices manually.
-// [ ] Platform: Missing gamepad support.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2022-11-30: Renderer: Restoring using al_draw_indexed_prim() when Allegro version is >= 5.2.5.
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-// 2022-01-17: Inputs: always calling io.AddKeyModsEvent() next and before key event (not in NewFrame) to fix input queue with very low framerates.
-// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-// 2021-12-08: Renderer: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
-// 2021-08-17: Calling io.AddFocusEvent() on ALLEGRO_EVENT_DISPLAY_SWITCH_OUT/ALLEGRO_EVENT_DISPLAY_SWITCH_IN events.
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-05-19: Renderer: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-// 2021-02-18: Change blending equation to preserve alpha in output buffer.
-// 2020-08-10: Inputs: Fixed horizontal mouse wheel direction.
-// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
-// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
-// 2019-05-11: Inputs: Don't filter character value from ALLEGRO_EVENT_KEY_CHAR before calling AddInputCharacter().
-// 2019-04-30: Renderer: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-// 2018-11-30: Platform: Added touchscreen support.
-// 2018-11-30: Misc: Setting up io.BackendPlatformName/io.BackendRendererName so they can be displayed in the About Window.
-// 2018-06-13: Platform: Added clipboard support (from Allegro 5.1.12).
-// 2018-06-13: Renderer: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-// 2018-06-13: Renderer: Stopped using al_draw_indexed_prim() as it is buggy in Allegro's DX9 backend.
-// 2018-06-13: Renderer: Backup/restore transform and clipping rectangle.
-// 2018-06-11: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-// 2018-04-18: Misc: Renamed file from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
-// 2018-04-18: Misc: Added support for 32-bit vertex indices to avoid conversion at runtime. Added imconfig_allegro5.h to enforce 32-bit indices when included from imgui.h.
-// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplAllegro5_RenderDrawData() in the .h file so you can call it yourself.
-// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.

-// dear imgui: Renderer + Platform Backend for Allegro 5
-// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)
-
-// Implemented features:
-// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
-// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy ALLEGRO_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-// [X] Platform: Clipboard support (from Allegro 5.1.12)
-// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
-// Issues:
-// [ ] Renderer: The renderer is suboptimal as we need to unindex our buffers and convert vertices manually.
-// [ ] Platform: Missing gamepad support.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).

-// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy AKEYCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
-// Missing features:
-// [ ] Platform: Clipboard support.
-// [ ] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-// [ ] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: Check if this is even possible with Android.
-// Important:
-// - Consider using SDL or GLFW backend on Android, which will be more full-featured than this.
-// - FIXME: On-screen keyboard currently needs to be enabled by the application (see examples/ and issue #3446)
-// - FIXME: Unicode character inputs needs to be passed by Dear ImGui by the application (see examples/ and issue #3446)
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-// 2021-03-04: Initial version.

-// (minor and older changes stripped away, please see git history for details)
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-05-19: DirectX10: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-// 2021-02-18: DirectX10: Change blending equation to preserve alpha in output buffer.
-// 2019-07-21: DirectX10: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData().
-// 2019-05-29: DirectX10: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
-// 2019-04-30: DirectX10: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
-// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-// 2018-07-13: DirectX10: Fixed unreleased resources in Init and Shutdown functions.
-// 2018-06-08: Misc: Extracted imgui_impl_dx10.cpp/.h away from the old combined DX10+Win32 example.
-// 2018-06-08: DirectX10: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-// 2018-04-09: Misc: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) on other backends.
-// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX10_RenderDrawData() in the .h file so you can call it yourself.
-// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-// 2016-05-07: DirectX10: Disabling depth-write.

-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
-// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
-// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
-// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
-// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
-// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
-// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
-// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.

-// dear imgui: Renderer Backend for DirectX12

-// Implemented features:

-// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
-
-// Important: to compile on 32-bit systems, this backend requires code to be compiled with '#define ImTextureID ImU64'.
-// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
-// To build this on 32-bit systems:
-// - [Solution 1] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'ImTextureID=ImU64' (this is what we do in the 'example_win32_direct12/example_win32_direct12.vcxproj' project file)
-// - [Solution 2] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'IMGUI_USER_CONFIG="my_imgui_config.h"' and inside 'my_imgui_config.h' add '#define ImTextureID ImU64' and as many other options as you like.
-// - [Solution 3] IDE/msbuild: edit imconfig.h and add '#define ImTextureID ImU64' (prefer solution 2 to create your own config file!)
-// - [Solution 4] command-line: add '/D ImTextureID=ImU64' to your cl.exe command-line (this is what we do in the example_win32_direct12/build_win32.bat file)

-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-05-19: DirectX12: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-// 2021-02-18: DirectX12: Change blending equation to preserve alpha in output buffer.
-// 2021-01-11: DirectX12: Improve Windows 7 compatibility (for D3D12On7) by loading d3d12.dll dynamically.
-// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
-// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
-// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
-// 2019-05-29: DirectX12: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
-// 2019-04-30: DirectX12: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-// 2019-03-29: Misc: Various minor tidying up.
-// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
-// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-// 2018-06-12: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from NewFrame() to RenderDrawData().
-// 2018-06-08: Misc: Extracted imgui_impl_dx12.cpp/.h away from the old combined DX12+Win32 example.
-// 2018-06-08: DirectX12: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle (to ease support for future multi-viewport).
-// 2018-02-22: Merged into master with all Win32 code synchronized to other examples.

-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-06-25: DirectX9: Explicitly disable texture state stages after >= 1.
-// 2021-05-19: DirectX9: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-// 2021-04-23: DirectX9: Explicitly setting up more graphics states to increase compatibility with unusual non-default states.
-// 2021-03-18: DirectX9: Calling IDirect3DStateBlock9::Capture() after CreateStateBlock() as a workaround for state restoring issues (see #3857).
-// 2021-03-03: DirectX9: Added support for IMGUI_USE_BGRA_PACKED_COLOR in user's imconfig file.
-// 2021-02-18: DirectX9: Change blending equation to preserve alpha in output buffer.

-// 2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-// 2019-03-29: Misc: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects().
-// 2019-01-16: Misc: Disabled fog before drawing UI's. Fixes issue #2288.
-// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-// 2018-06-08: Misc: Extracted imgui_impl_dx9.cpp/.h away from the old combined DX9+Win32 example.

-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2023-12-19: Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to register canvas selector and auto-resize GLFW window.
-// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys.
-// 2023-07-18: Inputs: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFLags_NoMouse if desired. (#5625, #6609)
-// 2023-06-12: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser + Emscripten. (#6491)
-// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen on Windows ONLY, using a custom WndProc hook. (#2702)
-// 2023-03-16: Inputs: Fixed key modifiers handling on secondary viewports (docking branch). Broken on 2023/01/04. (#6248, #6034)
-// 2023-03-14: Emscripten: Avoid using glfwGetError() and glfwGetGamepadState() which are not correctly implemented in Emscripten emulation. (#6240)
-// 2023-02-03: Emscripten: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096)
-// 2023-01-04: Inputs: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW, turns out they were faulty.
-// 2022-11-22: Perform a dummy glfwGetError() read to cancel missing names with glfwGetKeyName(). (#5908)
-// 2022-10-18: Perform a dummy glfwGetError() read to cancel missing mouse cursors errors. Using GLFW_VERSION_COMBINED directly. (#5785)
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-// 2022-09-01: Inputs: Honor GLFW_CURSOR_DISABLED by not setting mouse position *EDIT* Reverted 2023-07-18.
-// 2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
-// 2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.
-// 2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after initializing backend.
-// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
-// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
-// 2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
-// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-// 2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
-// 2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().
-// 2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
-// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
-// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
-// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
-// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
-// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
-// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
-// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
-// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
-// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
-// 2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
-// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
-// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
-// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
-// 2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
-// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
-// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
-// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
-// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

-// dear imgui: Platform Backend for GLFW
-// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
-// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
-
-// Implemented features:
-// [X] Platform: Clipboard support.
-// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
-// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

-// - FAQ https://dearimgui.com/faq

-// dear imgui: Platform Backend for GLUT/FreeGLUT
-// This needs to be used along with a Renderer (e.g. OpenGL2)
-
-// !!! GLUT/FreeGLUT IS OBSOLETE PREHISTORIC SOFTWARE. Using GLUT is not recommended unless you really miss the 90's. !!!
-// !!! If someone or something is teaching you GLUT today, you are being abused. Please show some resistance. !!!
-// !!! Nowadays, prefer using GLFW or SDL instead!
-
-// Implemented features:
-// [X] Platform: Partial keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLUT values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-// Issues:
-// [ ] Platform: GLUT is unable to distinguish e.g. Backspace from CTRL+H or TAB from CTRL+I
-// [ ] Platform: Missing horizontal mouse wheel support.
-// [ ] Platform: Missing mouse cursor shape/visibility support.
-// [ ] Platform: Missing clipboard support (not supported by Glut).
-// [ ] Platform: Missing gamepad support.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2023-04-17: BREAKING: Removed call to ImGui::NewFrame() from ImGui_ImplGLUT_NewFrame(). Needs to be called from the main application loop, like with every other backends.
-// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-// 2019-04-03: Misc: Renamed imgui_impl_freeglut.cpp/.h to imgui_impl_glut.cpp/.h.
-// 2019-03-25: Misc: Made io.DeltaTime always above zero.
-// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
-// 2018-03-22: Added GLUT Platform binding.

-// dear imgui: Renderer Backend for OpenGL2 (legacy OpenGL, fixed pipeline)
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
-// **Prefer using the code in imgui_impl_opengl3.cpp**
-// This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read.
-// If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more
-// complicated, will require your code to reset every single OpenGL attributes to their initial state, and might
-// confuse your GPU driver.
-// The GL2 code is unable to reset attributes or even call e.g. "glUseProgram(0)" because they don't exist in that API.
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2021-12-08: OpenGL: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-05-19: OpenGL: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-// 2021-01-03: OpenGL: Backup, setup and restore GL_SHADE_MODEL state, disable GL_STENCIL_TEST and disable GL_NORMAL_ARRAY client state to increase compatibility with legacy OpenGL applications.
-// 2020-01-23: OpenGL: Backup, setup and restore GL_TEXTURE_ENV to increase compatibility with legacy OpenGL applications.
-// 2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-// 2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
-// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-// 2018-08-03: OpenGL: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications.
-// 2018-06-08: Misc: Extracted imgui_impl_opengl2.cpp/.h away from the old combined GLFW/SDL+OpenGL2 examples.
-// 2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplOpenGL2_RenderDrawData() in the .h file so you can call it yourself.
-// 2017-09-01: OpenGL: Save and restore current polygon mode.
-// 2016-09-10: OpenGL: Uploading font texture as RGBA32 to increase compatibility with users shaders (not ideal).
-// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.

-// dear imgui: Renderer Backend for modern OpenGL with shaders / programmatic pipeline
-// - Desktop GL: 2.x 3.x 4.x
-// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
-// [x] Renderer: Large meshes support (64k+ vertices) with 16-bit indices (Desktop OpenGL only).
-
-// About WebGL/ES:
-// - You need to '#define IMGUI_IMPL_OPENGL_ES2' or '#define IMGUI_IMPL_OPENGL_ES3' to use WebGL or OpenGL ES.
-// - This is done automatically on iOS, Android and Emscripten targets.
-// - For other targets, the define needs to be visible from the imgui_impl_opengl3.cpp compilation unit. If unsure, define globally or in imconfig.h.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// About GLSL version:
-// The 'glsl_version' initialization parameter should be nullptr (default) or a "#version XXX" string.
-// On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
-// Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.

-// We embed our own OpenGL loader to not require user to provide their own or to have to use ours,

-// Our loader is custom-generated, based on gl3w but automatically filtered to only include

-//
-// YOU SHOULD NOT NEED TO INCLUDE/USE THIS DIRECTLY. THIS IS USED BY imgui_impl_opengl3.cpp ONLY.

-//
-// IF YOU GET BUILD ERRORS IN THIS FILE (commonly macro redefinitions or function redefinitions):
-// IT LIKELY MEANS THAT YOU ARE BUILDING 'imgui_impl_opengl3.cpp' OR INCUDING 'imgui_impl_opengl3_loader.h'
-// IN THE SAME COMPILATION UNIT AS ONE OF YOUR FILE WHICH IS USING A THIRD-PARTY OPENGL LOADER.
-// (e.g. COULD HAPPEN IF YOU ARE DOING A UNITY/JUMBO BUILD, OR INCLUDING .CPP FILES FROM OTHERS)
-// YOU SHOULD NOT BUILD BOTH IN THE SAME COMPILATION UNIT.
-// BUT IF YOU REALLY WANT TO, you can '#define IMGUI_IMPL_OPENGL_LOADER_CUSTOM' and imgui_impl_opengl3.cpp

-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F20 function keys. Stopped mapping F13 into PrintScreen.
-// 2023-04-09: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_Pen.
-// 2023-02-01: Fixed scroll wheel scaling for devices emitting events with hasPreciseScrollingDeltas==false (e.g. non-Apple mices).
-// 2022-11-02: Fixed mouse coordinates before clicking the host window.
-// 2022-10-06: Fixed mouse inputs on flipped views.
-// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-// 2022-05-03: Inputs: Removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture.
-// 2022-04-27: Misc: Store backend data in a per-context struct, allowing to use this backend with multiple contexts.
-// 2022-03-22: Inputs: Monitor NSKeyUp events to catch missing keyUp for key when user press Cmd + key
-// 2022-02-07: Inputs: Forward keyDown/keyUp events to OS when unused by dear imgui.
-// 2022-01-31: Fixed building with old Xcode versions that are missing gamepad features.
-// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
-// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-// 2022-01-12: Inputs: Added basic Platform IME support, hooking the io.SetPlatformImeDataFn() function.
-// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-// 2021-12-13: *BREAKING CHANGE* Add NSView parameter to ImGui_ImplOSX_Init(). Generally fix keyboard support. Using kVK_* codes for keyboard keys.
-// 2021-12-13: Add game controller support.
-// 2021-09-21: Use mach_absolute_time as CFAbsoluteTimeGetCurrent can jump backwards.
-// 2021-08-17: Calling io.AddFocusEvent() on NSApplicationDidBecomeActiveNotification/NSApplicationDidResignActiveNotification events.
-// 2021-06-23: Inputs: Added a fix for shortcuts using CTRL key instead of CMD key.
-// 2021-04-19: Inputs: Added a fix for keys remaining stuck in pressed state when CMD-tabbing into different application.
-// 2021-01-27: Inputs: Added a fix for mouse position not being reported when mouse buttons other than left one are down.
-// 2020-10-28: Inputs: Added a fix for handling keypad-enter key.
-// 2020-05-25: Inputs: Added a fix for missing trackpad clicks when done with "soft tap".
-// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
-// 2019-10-11: Inputs: Fix using Backspace key.
-// 2019-07-21: Re-added clipboard handlers as they are not enabled by default in core imgui.cpp (reverted 2019-05-18 change).
-// 2019-05-28: Inputs: Added mouse cursor shape and visibility support.
-// 2019-05-18: Misc: Removed clipboard handlers as they are now supported by core imgui.cpp.
-// 2019-05-11: Inputs: Don't filter character values before calling AddInputCharacter() apart from 0xF700..0xFFFF range.
-// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.

- KeyEventResponder implements the NSTextInputClient protocol as is required by the macOS text input manager.
-
- The macOS text input manager is invoked by calling the interpretKeyEvents method from the keyDown method.
- Keyboard events are then evaluated by the macOS input manager and valid text input is passed back via the
- insertText:replacementRange method.
-
- This is the same approach employed by other cross-platform libraries such as SDL2:
- https://github.com/spurious/SDL-mirror/blob/e17aacbd09e65a4fd1e166621e011e581fb017a8/src/video/cocoa/SDL_cocoakeyboard.m#L53

-// dear imgui: Platform Backend for SDL2
-// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
-// (Info: SDL2 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
-// (Prefer SDL 2.0.5+ for full feature support.)
-
-// Implemented features:
-// [X] Platform: Clipboard support.
-// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
-// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
-// [X] Platform: Basic IME support. App needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
-// 2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
-// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
-// 2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
-// 2023-02-07: Implement IME handler (io.SetPlatformImeDataFn will call SDL_SetTextInputRect()/SDL_StartTextInput()).
-// 2023-02-07: *BREAKING CHANGE* Renamed this backend file from imgui_impl_sdl.cpp/.h to imgui_impl_sdl2.cpp/.h in prevision for the future release of SDL3.
-// 2023-02-02: Avoid calling SDL_SetCursor() when cursor has not changed, as the function is surprisingly costly on Mac with latest SDL (may be fixed in next SDL version).
-// 2023-02-02: Added support for SDL 2.0.18+ preciseX/preciseY mouse wheel data for smooth scrolling + Scaling X value on Emscripten (bug?). (#4019, #6096)
-// 2023-02-02: Removed SDL_MOUSEWHEEL value clamping, as values seem correct in latest Emscripten. (#4019)
-// 2023-02-01: Flipping SDL_MOUSEWHEEL 'wheel.x' value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2022-09-26: Inputs: Disable SDL 2.0.22 new "auto capture" (SDL_HINT_MOUSE_AUTO_CAPTURE) which prevents drag and drop across windows for multi-viewport support + don't capture when drag and dropping. (#5710)
-// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-// 2022-03-22: Inputs: Fix mouse position issues when dragging outside of boundaries. SDL_CaptureMouse() erroneously still gives out LEAVE events when hovering OS decorations.
-// 2022-03-22: Inputs: Added support for extra mouse buttons (SDL_BUTTON_X1/SDL_BUTTON_X2).
-// 2022-02-04: Added SDL_Renderer* parameter to ImGui_ImplSDL2_InitForSDLRenderer(), so we can use SDL_GetRendererOutputSize() instead of SDL_GL_GetDrawableSize() when bound to a SDL_Renderer.
-// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
-// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
-// 2022-01-12: Update mouse inputs using SDL_MOUSEMOTION/SDL_WINDOWEVENT_LEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
-// 2022-01-12: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
-// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-// 2021-08-17: Calling io.AddFocusEvent() on SDL_WINDOWEVENT_FOCUS_GAINED/SDL_WINDOWEVENT_FOCUS_LOST.
-// 2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using SDL_GetMouseFocus() + SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH, requires SDL 2.0.5+)
-// 2021-06-29: *BREAKING CHANGE* Removed 'SDL_Window* window' parameter to ImGui_ImplSDL2_NewFrame() which was unnecessary.
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-03-22: Rework global mouse pos availability check listing supported platforms explicitly, effectively fixing mouse access on Raspberry Pi. (#2837, #3950)
-// 2020-05-25: Misc: Report a zero display-size when window is minimized, to be consistent with other backends.
-// 2020-02-20: Inputs: Fixed mapping for ImGuiKey_KeyPadEnter (using SDL_SCANCODE_KP_ENTER instead of SDL_SCANCODE_RETURN2).
-// 2019-12-17: Inputs: On Wayland, use SDL_GetMouseState (because there is no global mouse state).
-// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
-// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
-// 2019-04-23: Inputs: Added support for SDL_GameController (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
-// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
-// 2018-12-21: Inputs: Workaround for Android/iOS which don't seem to handle focus related calls.
-// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
-// 2018-11-14: Changed the signature of ImGui_ImplSDL2_ProcessEvent() to take a 'const SDL_Event*'.
-// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
-// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
-// 2018-06-08: Misc: Extracted imgui_impl_sdl.cpp/.h away from the old combined SDL2+OpenGL/Vulkan examples.
-// 2018-06-08: Misc: ImGui_ImplSDL2_InitForOpenGL() now takes a SDL_GLContext parameter.
-// 2018-05-09: Misc: Fixed clipboard paste memory leak (we didn't call SDL_FreeMemory on the data returned by SDL_GetClipboardText).
-// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-// 2018-02-16: Inputs: Added support for mouse cursors, honoring ImGui::GetMouseCursor() value.
-// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
-// 2018-02-05: Misc: Using SDL_GetPerformanceCounter() instead of SDL_GetTicks() to be able to handle very high framerate (1000+ FPS).
-// 2018-02-05: Inputs: Keyboard mapping is using scancodes everywhere instead of a confusing mixture of keycodes and scancodes.
-// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
-// 2018-01-19: Inputs: When available (SDL 2.0.4+) using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging. Otherwise (SDL 2.0.3 and before) testing for SDL_WINDOW_INPUT_FOCUS instead of SDL_WINDOW_MOUSE_FOCUS.
-// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
-// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
-// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

-// (minor and older changes stripped away, please see git history for details)
-// 2023-11-13: Updated for recent SDL3 API changes.
-// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
-// 2023-05-04: Fixed build on Emscripten/iOS/Android. (#6391)
-// 2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
-// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
-// 2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
-// 2023-02-07: Forked "imgui_impl_sdl2" into "imgui_impl_sdl3". Removed version checks for old feature. Refer to imgui_impl_sdl2.cpp for older changelog.

-// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
-// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]

-// dear imgui: Renderer Backend for Vulkan
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-// [!] Renderer: User texture binding. Use 'VkDescriptorSet' as ImTextureID. Read the FAQ about ImTextureID! See https://github.com/ocornut/imgui/pull/914 for discussions.
-// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
-
-// Important: on 32-bit systems, user texture binding is only supported if your imconfig file has '#define ImTextureID ImU64'.
-// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
-// To build this on 32-bit systems and support texture changes:
-// - [Solution 1] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'ImTextureID=ImU64' (this is what we do in our .vcxproj files)
-// - [Solution 2] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'IMGUI_USER_CONFIG="my_imgui_config.h"' and inside 'my_imgui_config.h' add '#define ImTextureID ImU64' and as many other options as you like.
-// - [Solution 3] IDE/msbuild: edit imconfig.h and add '#define ImTextureID ImU64' (prefer solution 2 to create your own config file!)
-// - [Solution 4] command-line: add '/D ImTextureID=ImU64' to your cl.exe command-line (this is what we do in our batch files)
-
-// The aim of imgui_impl_vulkan.h/.cpp is to be usable in your engine without any modification.
-// IF YOU FEEL YOU NEED TO MAKE ANY CHANGE TO THIS CODE, please share them and your feedback at https://github.com/ocornut/imgui/
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.
-// - Common ImGui_ImplVulkan_XXX functions and structures are used to interface with imgui_impl_vulkan.cpp/.h.
-// You will use those if you want to use this rendering backend in your engine/app.
-// - Helper ImGui_ImplVulkanH_XXX functions and structures are only used by this example (main.cpp) and by
-// the backend itself (imgui_impl_vulkan.cpp), but should PROBABLY NOT be used by your own engine/app code.
-// Read comments in imgui_impl_vulkan.h.
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2024-01-11: Vulkan: Fixed vkMapMemory() calls unnecessarily using full buffer size (#3957). Fixed MinAllocationSize handing (#7189).
-// 2024-01-03: Vulkan: Added MinAllocationSize field in ImGui_ImplVulkan_InitInfo to workaround zealous "best practice" validation layer. (#7189, #4238)
-// 2024-01-03: Vulkan: Stoped creating command pools with VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT as we don't reset them.
-// 2023-11-29: Vulkan: Fixed mismatching allocator passed to vkCreateCommandPool() vs vkDestroyCommandPool(). (#7075)
-// 2023-11-10: *BREAKING CHANGE*: Removed parameter from ImGui_ImplVulkan_CreateFontsTexture(): backend now creates its own command-buffer to upload fonts.
-// *BREAKING CHANGE*: Removed ImGui_ImplVulkan_DestroyFontUploadObjects() which is now unecessary as we create and destroy those objects in the backend.
-// ImGui_ImplVulkan_CreateFontsTexture() is automatically called by NewFrame() the first time.
-// You can call ImGui_ImplVulkan_CreateFontsTexture() again to recreate the font atlas texture.
-// Added ImGui_ImplVulkan_DestroyFontsTexture() but you probably never need to call this.
-// 2023-07-04: Vulkan: Added optional support for VK_KHR_dynamic_rendering. User needs to set init_info->UseDynamicRendering = true and init_info->ColorAttachmentFormat.
-// 2023-01-02: Vulkan: Fixed sampler passed to ImGui_ImplVulkan_AddTexture() not being honored + removed a bunch of duplicate code.
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2022-10-04: Vulkan: Added experimental ImGui_ImplVulkan_RemoveTexture() for api symetry. (#914, #5738).
-// 2022-01-20: Vulkan: Added support for ImTextureID as VkDescriptorSet. User need to call ImGui_ImplVulkan_AddTexture(). Building for 32-bit targets requires '#define ImTextureID ImU64'. (#914).
-// 2021-10-15: Vulkan: Call vkCmdSetScissor() at the end of render a full-viewport to reduce likehood of issues with people using VK_DYNAMIC_STATE_SCISSOR in their app without calling vkCmdSetScissor() explicitly every frame.
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-03-22: Vulkan: Fix mapped memory validation error when buffer sizes are not multiple of VkPhysicalDeviceLimits::nonCoherentAtomSize.
-// 2021-02-18: Vulkan: Change blending equation to preserve alpha in output buffer.
-// 2021-01-27: Vulkan: Added support for custom function load and IMGUI_IMPL_VULKAN_NO_PROTOTYPES by using ImGui_ImplVulkan_LoadFunctions().
-// 2020-11-11: Vulkan: Added support for specifying which subpass to reference during VkPipeline creation.
-// 2020-09-07: Vulkan: Added VkPipeline parameter to ImGui_ImplVulkan_RenderDrawData (default to one passed to ImGui_ImplVulkan_Init).
-// 2020-05-04: Vulkan: Fixed crash if initial frame has no vertices.
-// 2020-04-26: Vulkan: Fixed edge case where render callbacks wouldn't be called if the ImDrawData didn't have vertices.
-// 2019-08-01: Vulkan: Added support for specifying multisample count. Set ImGui_ImplVulkan_InitInfo::MSAASamples to one of the VkSampleCountFlagBits values to use, default is non-multisampled as before.
-// 2019-05-29: Vulkan: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
-// 2019-04-30: Vulkan: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-// 2019-04-04: *BREAKING CHANGE*: Vulkan: Added ImageCount/MinImageCount fields in ImGui_ImplVulkan_InitInfo, required for initialization (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). Added ImGui_ImplVulkan_SetMinImageCount().
-// 2019-04-04: Vulkan: Added VkInstance argument to ImGui_ImplVulkanH_CreateWindow() optional helper.
-// 2019-04-04: Vulkan: Avoid passing negative coordinates to vkCmdSetScissor, which debug validation layers do not like.
-// 2019-04-01: Vulkan: Support for 32-bit index buffer (#define ImDrawIdx unsigned int).
-// 2019-02-16: Vulkan: Viewport and clipping rectangles correctly using draw_data->FramebufferScale to allow retina display.
-// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-// 2018-08-25: Vulkan: Fixed mishandled VkSurfaceCapabilitiesKHR::maxImageCount=0 case.
-// 2018-06-22: Inverted the parameters to ImGui_ImplVulkan_RenderDrawData() to be consistent with other backends.
-// 2018-06-08: Misc: Extracted imgui_impl_vulkan.cpp/.h away from the old combined GLFW+Vulkan example.
-// 2018-06-08: Vulkan: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-// 2018-03-03: Vulkan: Various refactor, created a couple of ImGui_ImplVulkanH_XXX helper that the example can use and that viewport support will use.
-// 2018-03-01: Vulkan: Renamed ImGui_ImplVulkan_Init_Info to ImGui_ImplVulkan_InitInfo and fields to match more closely Vulkan terminology.
-// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback, ImGui_ImplVulkan_Render() calls ImGui_ImplVulkan_RenderDrawData() itself.
-// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-// 2017-05-15: Vulkan: Fix scissor offset being negative. Fix new Vulkan validation warnings. Set required depth member for buffer image copy.
-// 2016-11-13: Vulkan: Fix validation layer warnings and errors and redeclare gl_PerVertex.
-// 2016-10-18: Vulkan: Add location decorators & change to use structs as in/out in glsl, update embedded spv (produced with glslangValidator -x). Null the released resources.
-// 2016-08-27: Vulkan: Fix Vulkan example for use when a depth buffer is active.

-// Internal / Miscellaneous Vulkan Helpers
-// (Used by example's main.cpp. Used by multi-viewport features. PROBABLY NOT used by your own app.)
-//-------------------------------------------------------------------------
-// You probably do NOT need to use or care about those functions.
-// Those functions only exist because:
-// 1) they facilitate the readability and maintenance of the multiple main.cpp examples files.
-// 2) the upcoming multi-viewport feature will need them internally.
-// Generally we avoid exposing any kind of superfluous high-level helpers in the backends,
-// but it is too much code to duplicate everywhere so we exceptionally expose them.
-//
-// Your engine/app will likely _already_ have code to setup all that stuff (swap chain, render pass, frame buffers, etc.).
-// You may read this code to learn about Vulkan, but it is recommended you use you own custom tailored code to do equivalent work.

-// dear imgui: Renderer Backend for Vulkan
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-// [!] Renderer: User texture binding. Use 'VkDescriptorSet' as ImTextureID. Read the FAQ about ImTextureID! See https://github.com/ocornut/imgui/pull/914 for discussions.
-// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
-
-// Important: on 32-bit systems, user texture binding is only supported if your imconfig file has '#define ImTextureID ImU64'.
-// See imgui_impl_vulkan.cpp file for details.
-
-// The aim of imgui_impl_vulkan.h/.cpp is to be usable in your engine without any modification.
-// IF YOU FEEL YOU NEED TO MAKE ANY CHANGE TO THIS CODE, please share them and your feedback at https://github.com/ocornut/imgui/
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.
-// - Common ImGui_ImplVulkan_XXX functions and structures are used to interface with imgui_impl_vulkan.cpp/.h.
-// You will use those if you want to use this rendering backend in your engine/app.
-// - Helper ImGui_ImplVulkanH_XXX functions and structures are only used by this example (main.cpp) and by
-// the backend itself (imgui_impl_vulkan.cpp), but should PROBABLY NOT be used by your own engine/app code.
-// Read comments in imgui_impl_vulkan.h.

-// dear imgui: Renderer for WebGPU
-// This needs to be used along with a Platform Binding (e.g. GLFW)
-// (Please note that WebGPU is currently experimental, will not run on non-beta browsers, and may break.)
-
-// Implemented features:
-// [X] Renderer: User texture binding. Use 'WGPUTextureView' as ImTextureID. Read the FAQ about ImTextureID!
-// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2023-07-13: Use WGPUShaderModuleWGSLDescriptor's code instead of source. use WGPUMipmapFilterMode_Linear instead of WGPUFilterMode_Linear. (#6602)
-// 2023-04-11: Align buffer sizes. Use WGSL shaders instead of precompiled SPIR-V.
-// 2023-04-11: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2023-01-25: Revert automatic pipeline layout generation (see https://github.com/gpuweb/gpuweb/issues/2470)
-// 2022-11-24: Fixed validation error with default depth buffer settings.
-// 2022-11-10: Fixed rendering when a depth buffer is enabled. Added 'WGPUTextureFormat depth_format' parameter to ImGui_ImplWGPU_Init().
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2021-11-29: Passing explicit buffer sizes to wgpuRenderPassEncoderSetVertexBuffer()/wgpuRenderPassEncoderSetIndexBuffer().
-// 2021-08-24: Fixed for latest specs.
-// 2021-05-24: Add support for draw_data->FramebufferScale.
-// 2021-05-19: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-// 2021-05-16: Update to latest WebGPU specs (compatible with Emscripten 2.0.20 and Chrome Canary 92).
-// 2021-02-18: Change blending equation to preserve alpha in output buffer.
-// 2021-01-28: Initial version.

-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
-// 2023-09-25: Inputs: Synthesize key-down event on key-up for VK_SNAPSHOT / ImGuiKey_PrintScreen as Windows doesn't emit it (same behavior as GLFW/SDL).
-// 2023-09-07: Inputs: Added support for keyboard codepage conversion for when application is compiled in MBCS mode and using a non-Unicode window.
-// 2023-04-19: Added ImGui_ImplWin32_InitForOpenGL() to facilitate combining raw Win32/Winapi with OpenGL. (#3218)
-// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen. (#2702)
-// 2023-02-15: Inputs: Use WM_NCMOUSEMOVE / WM_NCMOUSELEAVE to track mouse position over non-client area (e.g. OS decorations) when app is not focused. (#6045, #6162)
-// 2023-02-02: Inputs: Flipping WM_MOUSEHWHEEL (horizontal mouse-wheel) value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
-// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-// 2022-09-28: Inputs: Convert WM_CHAR values with MultiByteToWideChar() when window class was registered as MBCS (not Unicode).
-// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
-// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-// 2022-01-17: Inputs: always update key mods next and before a key event (not in NewFrame) to fix input queue with very low framerates.
-// 2022-01-12: Inputs: Update mouse inputs using WM_MOUSEMOVE/WM_MOUSELEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
-// 2022-01-12: Inputs: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
-// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-// 2021-12-16: Inputs: Fill VK_LCONTROL/VK_RCONTROL/VK_LSHIFT/VK_RSHIFT/VK_LMENU/VK_RMENU for completeness.
-// 2021-08-17: Calling io.AddFocusEvent() on WM_SETFOCUS/WM_KILLFOCUS messages.
-// 2021-08-02: Inputs: Fixed keyboard modifiers being reported when host window doesn't have focus.
-// 2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using TrackMouseEvent() to receive WM_MOUSELEAVE events).
-// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-// 2021-06-08: Fixed ImGui_ImplWin32_EnableDpiAwareness() and ImGui_ImplWin32_GetDpiScaleForMonitor() to handle Windows 8.1/10 features without a manifest (per-monitor DPI, and properly calls SetProcessDpiAwareness() on 8.1).
-// 2021-03-23: Inputs: Clearing keyboard down array when losing focus (WM_KILLFOCUS).
-// 2021-02-18: Added ImGui_ImplWin32_EnableAlphaCompositing(). Non Visual Studio users will need to link with dwmapi.lib (MinGW/gcc: use -ldwmapi).
-// 2021-02-17: Fixed ImGui_ImplWin32_EnableDpiAwareness() attempting to get SetProcessDpiAwareness from shcore.dll on Windows 8 whereas it is only supported on Windows 8.1.
-// 2021-01-25: Inputs: Dynamically loading XInput DLL.
-// 2020-12-04: Misc: Fixed setting of io.DisplaySize to invalid/uninitialized data when after hwnd has been closed.
-// 2020-03-03: Inputs: Calling AddInputCharacterUTF16() to support surrogate pairs leading to codepoint >= 0x10000 (for more complete CJK inputs)
-// 2020-02-17: Added ImGui_ImplWin32_EnableDpiAwareness(), ImGui_ImplWin32_GetDpiScaleForHwnd(), ImGui_ImplWin32_GetDpiScaleForMonitor() helper functions.
-// 2020-01-14: Inputs: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD/IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT.
-// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
-// 2019-05-11: Inputs: Don't filter value from WM_CHAR before calling AddInputCharacter().
-// 2019-01-17: Misc: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created in a different thread or parent.
-// 2019-01-17: Inputs: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages.
-// 2019-01-15: Inputs: Added support for XInput gamepads (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
-// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
-// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
-// 2018-06-10: Inputs: Fixed handling of mouse wheel messages to support fine position messages (typically sent by track-pads).
-// 2018-06-08: Misc: Extracted imgui_impl_win32.cpp/.h away from the old combined DX9/DX10/DX11/DX12 examples.
-// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
-// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
-// 2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
-// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
-// 2018-01-08: Inputs: Added mapping for ImGuiKey_Insert.
-// 2018-01-05: Inputs: Added WM_LBUTTONDBLCLK double-click handlers for window classes with the CS_DBLCLKS flag.
-// 2017-10-23: Inputs: Added WM_SYSKEYDOWN / WM_SYSKEYUP handlers so e.g. the VK_MENU key can be read.
-// 2017-10-23: Inputs: Using Win32 ::SetCapture/::GetCapture() to retrieve mouse positions outside the client area when dragging.
-// 2016-11-12: Inputs: Only call Win32 ::SetCursor(nullptr) when io.MouseDrawCursor is set.

-## Dear ImGui: Backends
-
-**The backends/ folder contains backends for popular platforms/graphics API, which you can use in
-your application or engine to easily integrate Dear ImGui.** Each backend is typically self-contained in a pair of files: imgui_impl_XXXX.cpp + imgui_impl_XXXX.h.
-
-- The 'Platform' backends are in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, and windowing.
- e.g. Windows ([imgui_impl_win32.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_win32.cpp)), GLFW ([imgui_impl_glfw.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_glfw.cpp)), SDL2 ([imgui_impl_sdl2.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_sdl2.cpp)), etc.
-
-- The 'Renderer' backends are in charge of: creating atlas texture, and rendering imgui draw data.
- e.g. DirectX11 ([imgui_impl_dx11.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp)), OpenGL/WebGL ([imgui_impl_opengl3.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_opengl3.cpp)), Vulkan ([imgui_impl_vulkan.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_vulkan.cpp)), etc.
-
-- For some high-level frameworks, a single backend usually handles both 'Platform' and 'Renderer' parts.
- e.g. Allegro 5 ([imgui_impl_allegro5.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_allegro5.cpp)). If you end up creating a custom backend for your engine, you may want to do the same.
-
-An application usually combines one Platform backend + one Renderer backend + main Dear ImGui sources.
-For example, the [example_win32_directx11](https://github.com/ocornut/imgui/tree/master/examples/example_win32_directx11) application combines imgui_impl_win32.cpp + imgui_impl_dx11.cpp. There are 20+ examples in the [examples/](https://github.com/ocornut/imgui/blob/master/examples/) folder. See [EXAMPLES.MD](https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md) for details.
-
-**Once Dear ImGui is setup and running, run and refer to `ImGui::ShowDemoWindow()` in imgui_demo.cpp for usage of the end-user API.**
-
-
-### What are backends?
-
-Dear ImGui is highly portable and only requires a few things to run and render, typically:
-
- - Required: providing mouse/keyboard inputs (fed into the `ImGuiIO` structure).
- - Required: uploading the font atlas texture into graphics memory.
- - Required: rendering indexed textured triangles with a clipping rectangle.
-
- Extra features are opt-in, our backends try to support as many as possible:
-
- - Optional: custom texture binding support.
- - Optional: clipboard support.
- - Optional: gamepad support.
- - Optional: mouse cursor shape support.
- - Optional: IME support.
- - Optional: multi-viewports support.
- etc.
-
-This is essentially what each backend is doing + obligatory portability cruft. Using default backends ensure you can get all those features including the ones that would be harder to implement on your side (e.g. multi-viewports support).
-
-It is important to understand the difference between the core Dear ImGui library (files in the root folder)
-and the backends which we are describing here (backends/ folder).
-
-- Some issues may only be backend or platform specific.
-- You should be able to write backends for pretty much any platform and any 3D graphics API.
- e.g. you can get creative and use software rendering or render remotely on a different machine.

-
-See "Getting Started" section of [EXAMPLES.MD](https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md) for more details.
-
-
-### List of backends
-
-In the [backends/](https://github.com/ocornut/imgui/blob/master/backends) folder:
-
-List of Platforms Backends:

-
-### Recommended Backends
-
-If you are not sure which backend to use, the recommended platform/frameworks for portable applications:
-
-|Library |Website |Backend |Note |
-|--------|--------|--------|-----|
-| GLFW | https://github.com/glfw/glfw | imgui_impl_glfw.cpp | |
-| SDL2 | https://www.libsdl.org | imgui_impl_sdl2.cpp | |
-| Sokol | https://github.com/floooh/sokol | [util/sokol_imgui.h](https://github.com/floooh/sokol/blob/master/util/sokol_imgui.h) | Lower-level than GLFW/SDL |
-
-
-### Using a custom engine?
-
-You will likely be tempted to start by rewrite your own backend using your own custom/high-level facilities...
-Think twice!
-
-If you are new to Dear ImGui, first try using the existing backends as-is.
-You will save lots of time integrating the library.
-You can LATER decide to rewrite yourself a custom backend if you really need to.
-In most situations, custom backends have fewer features and more bugs than the standard backends we provide.
-If you want portability, you can use multiple backends and choose between them either at compile time
-or at runtime.
-
-**Example A**: your engine is built over Windows + DirectX11 but you have your own high-level rendering
-system layered over DirectX11.
-Suggestion: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first.
-Once it works, if you really need it, you can replace the imgui_impl_dx11.cpp code with a
-custom renderer using your own rendering functions, and keep using the standard Win32 code etc.
-
-**Example B**: your engine runs on Windows, Mac, Linux and uses DirectX11, Metal, and Vulkan respectively.
-Suggestion: use multiple generic backends!
-Once it works, if you really need it, you can replace parts of backends with your own abstractions.
-
-**Example C**: your engine runs on platforms we can't provide public backends for (e.g. PS4/PS5, Switch),
-and you have high-level systems everywhere.
-Suggestion: try using a non-portable backend first (e.g. win32 + underlying graphics API) to get
-your desktop builds working first. This will get you running faster and get your acquainted with
-how Dear ImGui works and is setup. You can then rewrite a custom backend using your own engine API...
-
-Generally:
-It is unlikely you will add value to your project by creating your own backend.
-
-Also:
-The [multi-viewports feature](https://github.com/ocornut/imgui/issues/1542) of the 'docking' branch allows
-Dear ImGui windows to be seamlessly detached from the main application window. This is achieved using an
-extra layer to the Platform and Renderer backends, which allows Dear ImGui to communicate platform-specific
-requests such as: "create an additional OS window", "create a render context", "get the OS position of this
-window" etc. See 'ImGuiPlatformIO' for details.
-Supporting the multi-viewports feature correctly using 100% of your own abstractions is more difficult
-than supporting single-viewport.
-If you decide to use unmodified imgui_impl_XXXX.cpp files, you can automatically benefit from
-improvements and fixes related to viewports and platform windows without extra work on your side.

-
-WHEN TO UPDATE?
-
-- Keeping your copy of Dear ImGui updated regularly is recommended.
-- It is generally safe and recommended to sync to the latest commit in 'master' or 'docking'
- branches. The library is fairly stable and regressions tends to be fixed fast when reported.
-
-HOW TO UPDATE?
-
-- Update submodule or copy/overwrite every file.
-- About imconfig.h:
- - You may modify your copy of imconfig.h, in this case don't overwrite it.
- - or you may locally branch to modify imconfig.h and merge/rebase latest.
- - or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to
- specify a custom path for your imconfig.h file and instead not have to modify the default one.
-- Read the `Breaking Changes` section (in imgui.cpp or here in the Changelog).
-- If you have a problem with a missing function/symbols, search for its name in the code, there will likely be a comment about it.
-- If you are copying this repository in your codebase, please leave the demo and documentations files in there, they will be useful.
-- You may diff your previous Changelog with the one you just copied and read that diff.
-- You may enable `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in imconfig.h to forcefully disable legacy names and symbols.
- Doing it every once in a while is a good way to make sure you are not using obsolete symbols. Dear ImGui is in active development,
- and API updates have been a little more frequent lately. They are documented below and in imgui.cpp and should not affect all users.
-- Please report any issue!

------------------------------------------------------------------------
- VERSION 1.90.2 WIP (In Progress)
------------------------------------------------------------------------
-
-Breaking changes:
-
-Other changes:
-
-- Backends: Vulkan: Fixed vkMapMemory() calls unnecessarily using full buffer size. (#3957)
-- Backends: Vulkan: Fixed handling of ImGui_ImplVulkan_InitInfo::MinAllocationSize field. (#7189, #4238)
-
-
------------------------------------------------------------------------
- VERSION 1.90.1 (Released 2024-01-10)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.1
-
-Breaking changes:
-
-- imgui_freetype: commented out ImGuiFreeType::BuildFontAtlas() obsoleted in 1.81.
- Prefer using #define IMGUI_ENABLE_FREETYPE or see commented code for manual calls.
-- Removed CalcListClipping() marked obsolete in 1.86. (#3841)
- Prefer using ImGuiListClipper which can return non-contiguous ranges.
-- Internals, Columns: commented out legacy ImGuiColumnsFlags_XXX symbols redirecting
- to ImGuiOldColumnsFlags_XXX, obsoleted from imgui_internal.h in 1.80.
-- Commented out obsolete ImGuiKey_KeyPadEnter redirection to ImGuiKey_KeypadEnter. (#2625, #7143)
-
-Other changes:
-
-- Windows:
- - BeginChild(): Fixed auto-resizing erroneously limiting size to host viewport
- minus padding. There are no limit to a child width/height. (#7063) [@Devyre]
- - BeginChild(): Resize borders rendered even when ImGuiWindowFlags_NoBackground
- is specified. (#1710, #7194)
- - Fixed some auto-resizing path using style.WindowMinSize.x (instead of x/y)
- for both axises since 1.90. (#7106) [@n0bodysec]
- - Scrolling: internal scrolling value is rounded instead of truncated, as a way to reduce
- speed asymmetry when (incorrectly) attempting to scroll by non-integer amount. (#6677)
-- Navigation (Keyboard/gamepad):
- - Nav, IO: SetNextFrameWantCaptureKeyboard(false) calls are not overridden back to true when
- navigation is enabled. SetNextFrameWantCaptureKeyboard() is always higher priority. (#6997)
- - Nav: Activation can also be performed with Keypad Enter. (#5606)
-- Drag and Drop:
- - Fixed drop target highlight on items temporarily pushing a widened clip rect
- (namely Selectables and Treenodes using SpanAllColumn flag) so the highlight properly covers
- all columns. (#7049, #4281, #3272)
-- InputText:
- - InputTextMultiline: Fixed Tab character input not repeating (1.89.4 regression).
- - InputTextMultiline: Tabbing through a multi-line text editor which allows Tab character inputs
- (using the ImGuiInputTextFlags_AllowTabInput flag) doesn't automatically activate it, in order
- to allow passing through multiple widgets easily. (#3092, #5759, #787)
-- Drags, Sliders, Inputs:
- - DragScalarN, SliderScalarN, InputScalarN: Fixed incorrect pushes into ItemWidth
- stack when number of components is 1. [#7095] [@Nahor]
- - Drags, Sliders, Inputs: removed all attempts to filter non-numerical characters during text
- editing. Invalid inputs not applied to value, visibly reverted after validation. (#6810, #7096)
- - Drags, Sliders, Inputs: removal of filter means that "nan" and "inf" values may be input. (#7096)
- - DragScalarN, SliderScalarN, InputScalarN, PushMultiItemsWidths: improve multi-components
- width computation to better distribute the error. (#7120, #7121) [@Nahor]
-- Menus:
- - Tweaked hover slack logic, adding an extra timeout to avoid situations where a slow vertical
- movements toward another parent BeginMenu() can keep the wrong child menu open. (#6671, #6926)
-- Color Editors:
- - ColorEdit: Layout tweaks for very small sizes. (#7120, #7121)
- - ColorPicker: Fixed saturation/value cursor radius not scaling properly.
-- Tabs: Added ImGuiTabItemFlags_NoAssumedClosure to enable app to react on closure attempt,
- without having to draw an unsaved document marker (ImGuiTabItemFlags_UnsavedDocument sets
- _NoAssumedClosure automatically). (#7084)
-- Debug Tools:
- - Added io.ConfigDebugIsDebuggerPresent option. When enabled, this adds buttons in various
- locations of Metrics/Debugger to manually request a debugger break:
- - Request a debug break in a Begin() call.
- - Request a debug break in a ItemAdd() call via debug log and hovering 0xXXXXXX identifiers.
- - Request a debug break in a BeginTable() call.
- - Request a debug break in a SetShortcutRouting()/Shortcut() call. [Internal]
- - Metrics: Reorganize Tools menu.
- - Added DebugFlashStyleColor() to identify a style color. Added to Style Editor.
- - Debug Log: Hide its own clipper log to reduce noise in the output. (#5855)
- - Debug Log: Clicking any filter with SHIFT held enables it for 2 frames only,
- making it easier when dealing with spammy logs. (#5855)
-- Settings: Fixed an issue marking settings as dirty when merely clicking on a border or resize
- grip without moving it.
-- Misc: Added IMGUI_USER_H_FILENAME to change the path included when using
- IMGUI_INCLUDE_IMGUI_USER_H. (#7039) [@bryceberger]
-- Misc: Rework debug display of texture id in Metrics window to avoid compile-error when
- ImTextureID is defined to be larger than 64-bits. (#7090)
-- Misc: Added extra courtesy ==/!= operators when IMGUI_DEFINE_MATH_OPERATORS is defined.
-- Misc: Fixed text functions fast-path for handling "%s" and "%.*s" to handle null pointers gracefully,
- like most printf implementations. (#7016, #3466, #6846) [@codefrog2002]
-- Misc: Renamed some defines in imstb_textedit.h to avoid conflicts when using unity/jumbo builds
- on a codebase where another copy of the library is used.
-- Misc: During shutdown, check that io.BackendPlatformUserData and io.BackendRendererUserData are NULL
- in order to catch cases where backend was not shut down. (#7175)
-- Misc: Reworked Issue Template to a shinier and better form. (#5927) [@Panquesito7, @PathogenDavid, @ocornut]
-- Backends:
- - GLFW, Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to
- register canvas selector and auto-resize GLFW window. (#6751) [@Traveller23, @ypujante]
- - GLFW: Fixed Windows specific hooks to use Unicode version of WndProc even when
- compiling in MBCS mode. (#7174) [@kimidaisuki22]
- - OpenGL3: Update GL3W based imgui_impl_opengl3_loader.h to load libGL.so variants in
- case of missing symlink. Fix 1.90 regression for some distros. (#6983)
- - Vulkan: Fixed mismatching allocator passed to vkCreateCommandPool() vs
- vkDestroyCommandPool(). (#7075) [@FoonTheRaccoon]
- - Vulkan: Added MinAllocationSize field in ImGui_ImplVulkan_InitInfo to workaround zealous
- "best practice" validation layer. (#7189, #4238) [@philae-ael]
- - Vulkan: Stopped creating command pools with VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT
- as we don't reset them.
- - WebGPU: Fixed wgpuRenderPassEncoderSetScissorRect() crash when rendering modal window's
- dimming layer, which has an unclipped value in ImDrawCmd::ClipRect. (#7191) [@aparis69]
-- Examples:
- - Examples: GLFW+Emscripten: Fixed examples not consistently resizing according to host canvas.
- (#6751) [@Traveller23, @ypujante]
- - Examples: SDL3: Minor fixes following recent SDL3 in-progress development.

------------------------------------------------------------------------
- VERSION 1.90.0 (Released 2023-11-15)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90
-
-Breaking changes:
-
- - BeginChild(): Upgraded 'bool border = false' parameter to 'ImGuiChildFlags flags = 0'.
- Added ImGuiChildFlags_Border value. As with our prior "bool-to-flags" API updates,
- the ImGuiChildFlags_Border value is guaranteed to be == true forever to ensure a
- smoother transition, meaning all existing calls will still work.
- If you want to neatly transition your call sites:
- Before: BeginChild("Name", size, true)
- After: BeginChild("Name", size, ImGuiChildFlags_Border)
- Before: BeginChild("Name", size, false)
- After: BeginChild("Name", size) or BeginChild("Name", 0) or BeginChild("Name", size, ImGuiChildFlags_None)
- Existing code will still work as 'ImGuiChildFlags_Border == true', but you are encouraged to update call sites.
- - BeginChild(): Added child-flag ImGuiChildFlags_AlwaysUseWindowPadding as a replacement for
- the window-flag ImGuiWindowFlags_AlwaysUseWindowPadding: the feature only ever made sense
- for use with BeginChild() anyhow, passing it to Begin() had no effect. Now that we accept
- child-flags we are moving it there. (#462)
- Before: BeginChild("Name", size, 0, ImGuiWindowFlags_AlwaysUseWindowPadding);
- After: BeginChild("Name", size, ImGuiChildFlags_AlwaysUseWindowPadding, 0);
- Kept inline redirection enum (will obsolete later) so existing code will work.
- - BeginChildFrame()/EndChildFrame(): removed functions in favor of using BeginChild() with
- the ImGuiChildFlags_FrameStyle flag. Kept inline redirection function (will obsolete).
- Those functions were merely PushStyle/PopStyle helpers and custom versions are easy to create.
- (The removal isn't so much motivated by needing to add the feature in BeginChild(), but by the
- necessity to avoid BeginChildFrame() signature mismatching BeginChild() signature and features.)
- - Debug Tools: Renamed ShowStackToolWindow() ("Stack Tool") to ShowIDStackToolWindow() ("ID Stack Tool"),
- as earlier name was misleading. Kept inline redirection function. (#4631)
- - IO: Removed io.MetricsActiveAllocations introduced in 1.63, was displayed in Metrics and unlikely to
- be accessed by end-user. Value still visible in the UI and easily to recompute from a delta.
- - Defining IMGUI_DISABLE_OBSOLETE_FUNCTIONS now automatically defines IMGUI_DISABLE_OBSOLETE_KEYIO. (#4921)
- - Removed IM_OFFSETOF() macro in favor of using offsetof() available in C++11. Kept redirection define. (#4537)
- - ListBox, Combo: Changed signature of "name getter" callback in old one-liner ListBox()/Combo() apis.
- Before:
- getter type: bool (*getter)(void* user_data, int idx, const char** out_text)
- function: bool Combo(const char* label, int* current_item, bool (*getter)(void* user_data, int idx, const char** out_text), ...);
- function: bool ListBox(const char* label, int* current_item, bool (*getting)(void* user_data, int idx, const char** out_text), ...);
- After:
- getter type: const char* (*getter)(void* user_data, int idx)
- function: bool Combo(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);
- function: bool ListBox(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);
- Old type was unnecessarily complex and harder to wrap in e.g. a lambda. Kept inline redirection function (will obsolete).
- - Commented out obsolete redirecting enums/functions that were marked obsolete two years ago:
- - GetWindowContentRegionWidth() -> use GetWindowContentRegionMax().x - GetWindowContentRegionMin().x.
- Consider that generally 'GetContentRegionAvail().x' is often more correct and more useful.
- - ImDrawCornerFlags_XXX -> use ImDrawFlags_RoundCornersXXX names.
- Read 1.82 changelog for details + grep commented names in sources.
- - Commented out runtime support for hardcoded ~0 or 0x01..0x0F rounding flags values for
- AddRect()/AddRectFilled()/PathRect()/AddImageRounded(). -> Use ImDrawFlags_RoundCornersXXX flags.
- Read 1.82 changelog for details.
- - Backends: Vulkan: Removed parameter from ImGui_ImplVulkan_CreateFontsTexture(): backend now creates its own
- command-buffer to upload fonts. Removed ImGui_ImplVulkan_DestroyFontUploadObjects() which is now unnecessary.
- No need to call ImGui_ImplVulkan_CreateFontsTexture() as it is done automatically in ImGui_ImplVulkan_NewFrame().
- You can call ImGui_ImplVulkan_CreateFontsTexture() manually if you need to reload the font atlas texture.
- (#6943, #6715, #6327, #3743, #4618)
-
-Other changes:
-
-- Windows:
- - BeginChild(): Added ImGuiChildFlags_ResizeX and ImGuiChildFlags_ResizeY to allow resizing
- child windows from the bottom/right border (toward layout direction). Resized child windows
- settings are saved and persistent in .ini file. (#1710)
- - BeginChild(): Added ImGuiChildFlags_Border as a replacement for 'bool border = true' parameter.
- - BeginChild(): Added ImGuiChildFlags_AutoResizeX and ImGuiChildFlags_AutoResizeY to auto-resize
- on one axis, while generally providing a size on the other axis. (#1666, #1395, #1496, #1710)
- e.g. BeginChild("name", {-FLT_MIN, 0.0f}, ImGuiChildFlags_AutoResizeY);
- - Size is only reevaluated if the child window is within visible boundaries or just appearing.
- This allows coarse clipping to be performed and auto-resizing childs to return false when
- hidden because of being scrolled out.
- - Combining this with also specifying ImGuiChildFlags_AlwaysAutoResize disables
- this optimization, meaning child contents will never be clipped (not recommended).
- - Please be considerate that child are full windows and carry significant overhead:
- combining auto-resizing for both axises to create a non-scrolling child to merely draw
- a border would be better more optimally using BeginGroup(). (see #1496)
- (until we come up with new helpers for framed groups and work-rect adjustments).
- - BeginChild(): made it possible to use SetNextWindowSizeConstraints() rectangle, often
- useful when ImGuiChildFlags_AutoResizeX or ImGuiChildFlags_AutoResizeY. (#1666, #1395, #1496)
- Custom constraint callback are not supported with child window.
- - BeginChild(): Added ImGuiChildFlags_FrameStyle as a replacement for BeginChildFrame(),
- use it to make child window use FrameBg, FrameRounding, FrameBorderSize, FramePadding
- instead of ChildBg, ChildRounding, ChildBorderSize, WindowPadding.
- - Popups: clarified meaning of 'p_open != NULL' in BeginPopupModal() + set back user value
- to false when popup is closed in ways other than clicking the close button. (#6900)
- - Double-clicking lower-left resize grip auto-resize (like lower-right one).
- - Double-clicking bottom or right window border auto-resize on a singles axis.
- - Use relative mouse movement for border resize when the border geometry has moved
- (e.g. resizing a child window triggering parent scroll) in order to avoid resizing
- feedback loops. Unless manually mouse-wheeling while border resizing. (#1710)
-- Separators:
- - Altered end-points to use more standard boundaries. (#205, #4787, #1643)
- Left position is always current cursor X position, right position is always work-rect
- rightmost edge. It effectively means that:
- - A separator in the root of a window will end up a little more distant from edges
- than previously (essentially following WindowPadding instead of clipping edges).
- - A separator inside a table cell end up a little distance from edges instead of
- touching them (essentially following CellPadding instead of clipping edges).
- - Matches tree indentation (was not the case before).
- - Matches SeparatorText(). (#1643)
- - Makes things correct inside groups without specific/hard-coded handling. (#205)
- - Support legacy behavior when used inside old Columns(), as we favored that idiom back then,
- only different is left position follows indentation level, to match calling a Separator()
- inside or outside Columns().
-- Tooltips:
- - Made using SetItemTooltip()/IsItemHovered(ImGuiHoveredFlags_ForTooltip) defaults to
- activate tooltips on disabled items. This is done by adding ImGuiHoveredFlags_AllowWhenDisabled
- to the default value of style.HoverFlagsForTooltipMouse/HoverFlagsForTooltipNav. (#1485)
- - Made is possible to combine ImGuiHoveredFlags_ForTooltip with a ImGuiHoveredFlags_DelayXXX
- override. (#1485)
-- Drag and Drop:
- - Reworked drop target highlight: reduce rectangle to its visible portion, and then expand
- slightly. A full rectangle is always visible and it may protrude slightly. (#4281, #3272)
- - Fixed submitting a tooltip from drop target location when using AcceptDragDropPayload()
- with ImGuiDragDropFlags_AcceptNoPreviewTooltip and submitting a tooltip manually.
-- Tables:
- - Added angled headers support. You need to set ImGuiTableColumnFlags_AngledHeader on selected
- columns and call TableAngledHeadersRow(). Added style.TableAngledHeadersAngle style option.
- - Added ImGuiTableFlags_HighlightHoveredColumn flag, currently highlighting column header.
- - Fixed an edge-case when no columns are visible + table scrollbar is visible + user
- code is always testing return value of TableSetColumnIndex() to coarse clip. With an active
- clipper it would have asserted. Without a clipper, the scrollbar range would be wrong.
- - Request user to submit contents when outer host-window is requesting auto-resize,
- so a scrolling table can contribute to initial window size. (#6510)
- - Fixed subtle drawing overlap between borders in some situations.
- - Fixed bottom-most and right-most outer border offset by one. (#6765, #3752) [@v-ein]
- - Fixed top-most and left-most outer border overlapping inner clip-rect when scrolling. (#6765)
- - Fixed top-most outer border being drawn with both TableBorderLight and TableBorderStrong
- in some situations, causing the earlier to be visible underneath when alpha is not 1.0f.
- - Fixed right-clicking right-most section (past right-most column) from highlighting a column.
- - Fixed an issue with ScrollX enabled where an extraneous draw command would be created.
-- Menus:
- - Menus: Fixed a bug where activating an item in a child-menu and dragging mouse over the
- parent-menu would erroneously close the child-menu. (Regression from 1.88). (#6869)
- - MenuBar: Fixed an issue where layouting an item in the menu-bar would erroneously
- register contents size in a way that would affect the scrolling layer.
- Was most often noticeable when using an horizontal scrollbar. (#6789)
-- InputText:
- - InputTextMultiline: Fixed a crash pressing Down on last empty line of a multi-line buffer.
- (regression from 1.89.2, only happened in some states). (#6783, #6000)
- - InputTextMultiline: Fixed Tabbing cycle leading to a situation where Enter key wouldn't
- be accepted by the widget when navigation highlight is visible. (#6802, #3092, #5759, #787)
-- Nav: Tabbing always enable nav highlight when ImGuiConfigFlags_NavEnableKeyboard is set.
- Previously was inconsistent and only enabled when stepping through a non-input item.
- (#6802, #3092, #5759, #787)
-- TreeNode: Added ImGuiTreeNodeFlags_SpanAllColumns for use in tables. (#3151, #3565, #2451, #2438)
-- TabBar: Fixed position of unsaved document marker (ImGuiTabItemFlags_UnsavedDocument) which was
- accidentally offset in 1.89.9. (#6862) [@alektron]
-- ColorPicker4(): Fixed ImGuiColorEditFlags_NoTooltip not being forwarded to individual DragFloat3
- sub-widgets which have a visible color preview when ImGuiColorEditFlags_NoSidePreview is also set. (#6957)
-- BeginGroup(): Fixed a bug pushing line lower extent too far down when called after a call
- to SameLine() followed by manual cursor manipulation.
-- BeginCombo(): Added ImGuiComboFlags_WidthFitPreview flag. (#6881) [@mpv-enjoyer]
-- BeginListBox(): Fixed not consuming SetNextWindowXXX() data when returning false.
-- Fonts:
- - Argument 'float size_pixels' passed to AddFontXXX() functions is now rounded to lowest integer.
- This is because our layout/font system currently doesn't fully support non-integer sizes. Until
- it does, this has been a common pitfall leading to more or less subtle issues. (#3164, #3309, #6800)
- - Better assert during load when passing truncated font data or wrong data size. (#6822)
- - Ensure calling AddFontXXX function doesn't invalidates ImFont's ConfigData pointers
- prior to building again. (#6825)
- - Added ImFontConfig::RasterizerDensity field to increase texture size of rendered glyphs
- without altering other metrics. Among other things, this makes it easier to have zooming code
- swapping between 2 fonts (e.g. a 100% and a 400% fonts) depending on current scale. (#6925) [@thedmd]
- Important: if you increase this it is expected that you would render the font with a scale of
- similar value or magnitude. Merely increasing this without increasing scale may lower quality.
- - imgui_freetype: Added support for RasterizerDensity. (#6925) [@thedmd]
- - imgui_freetype: Fixed a warning and leak in IMGUI_ENABLE_FREETYPE_LUNASVG support. (#6842, #6591)
-- Inputs: Added IsKeyChordPressed() helper function e.g. IsKeyChordPressed(ImGuiMod_Ctrl | ImGuiKey_S).
- (note that ImGuiMod_Shortcut may be used as an alias for Cmd on OSX and Ctrl on other systems).
-- Misc: Most text functions also treat "%.*s" (along with "%s") specially to bypass formatting. (#3466, #6846)
-- IO: Add extra keys to ImGuiKey enum: ImGuiKey_F13 to ImGuiKey_F24. (#6891, #4921)
-- IO: Add extra keys to ImGuiKey enum: ImGuiKey_AppBack, ImGuiKey_AppForward. (#4921)
-- IO: Setting io.WantSetMousePos ignores incoming MousePos events. (#6837, #228) [@bertaye]
-- Debug Tools: Metrics: Added log of recent alloc/free calls.
-- Debug Tools: Metrics: Added "Show groups rectangles" in tools.
-- ImDrawList: Added AddEllipse(), AddEllipseFilled(), PathEllipticalArcTo(). (#2743) [@Doohl]
-- ImVector: Added find_index() helper.
-- Demo: Added "Drag and Drop -> Tooltip at target location" demo.
-- Demo: Added "Layout -> Child Windows -> Manual-resize" demo. (#1710)
-- Demo: Added "Layout -> Child Windows -> Auto-resize with constraints" demo. (#1666, #1395, #1496, #1710)
-- Demo: Partly fixed "Examples -> Constrained-resizing window" custom constrains demo. (#6210) [@cfillion]
-- Backends: Vulkan: Removed parameter from ImGui_ImplVulkan_CreateFontsTexture(): backend now creates its own
- command-buffer to upload fonts. Removed ImGui_ImplVulkan_DestroyFontUploadObjects() which is now unnecessary.
- No need to call ImGui_ImplVulkan_CreateFontsTexture() as it is done automatically in ImGui_ImplVulkan_NewFrame().
- You can call ImGui_ImplVulkan_CreateFontsTexture() manually if you need to reload font atlas texture.
- Fixed leaks, and added ImGui_ImplVulkan_DestroyFontsTexture() (probably no need to call this directly).

- doesn't emit it (same behavior as GLFW/SDL). (#6859) [@thedmd, @SuperWangKai]
-- Backends: OpenGL3: rename symbols in our internal loader so that LTO compilation with another

------------------------------------------------------------------------
- VERSION 1.89.9 (Released 2023-09-04)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.9
-
-Breaking changes:
-
-- Clipper: Renamed IncludeRangeByIndices(), also called ForceDisplayRangeByIndices()
- before 1.89.6, to IncludeItemsByIndex(). Kept inline redirection function. (#6424, #3841)
-
-Other changes:
-
-- Tables: Made it possible to use SameLine(0,0) after TableNextColumn() or
- TableSetColumnIndex() in order to reuse line pos/height from previous cell. (#3740)
-- Tables: Made it possible to change style.CellPadding.y between rows. (#3740)
-- Nav, TreeNode: Pressing Left with ImGuiTreeNodeFlags_NavLeftJumpsBackHere now goes
- through proper navigation logic: honor scrolling and selection. (#1079, #1131)
-- Sliders: Fixed an integer overflow and div-by-zero in SliderInt() when
- v_max=INT_MAX (#6675, #6679) [@jbarthelmes]
-- Windows: Layout of Close/Collapse buttons uses style.ItemInnerSpacing.x between items,
- stopped incorrectly using FramePadding in a way where hit-boxes could overlap when
- setting large values. (#6749)
-- TabBar, Style: added style.TabBarBorderSize and associated ImGuiStyleVar_TabBarBorderSize.
- Tweaked rendering of that separator to allow thicker values. (#6820, #4859, #5022, #5239)
-- InputFloat, SliderFloat, DragFloat: always turn both '.' and ',' into the current decimal
- point character when using Decimal/Scientific character filter. (#6719, #2278) [@adamsepp]
-- ColorEdit, ColorPicker: Manipulating options popup don't mark item as edited. (#6722)
- (Note that they may still be marked as Active/Hovered.)
-- Clipper: Added IncludeItemByIndex() helper to include a single item. (#6424, #3841)
-- Clipper: Fixed a bug if attempt to force-include a range which matches an already
- included range, clipper would end earlier. (#3841)
-- ImDrawData: Fixed an issue where TotalVtxCount/TotalIdxCount does not match the sum
- of individual ImDrawList's buffer sizes when a dimming/modal background is rendered. (#6716)
-- ImDrawList: Automatically calling ChannelsMerge() if not done after a split.
-- ImDrawList: Fixed OOB access in _CalcCircleAutoSegmentCount when passing excessively
- large radius to AddCircle(). (#6657, #5317) [@EggsyCRO, @jdpatdiscord]
-- IO: Exposed io.PlatformLocaleDecimalPoint to configure decimal point ('.' or ',') for
- languages needing it. Should ideally be set to the value of '*localeconv()->decimal_point'
- but our backends don't do it yet. (#6719, #2278)
-- IO: Fixed io.AddMousePosEvent() and io.AddMouseButtonEvent() writing MouseSource to
- wrong union section. Was semantically incorrect and accidentally had no side-effects
- with default compiler alignment settings. (#6727) [@RickHuang2001]
-- Misc: Made multiple calls to Render() during the same frame early out faster.
-- Debug Tools: Metrics: Fixed "Drawlists" section and per-viewport equivalent
- appearing empty (regression in 1.89.8).
-- Demo: Reorganized "Examples" menu.
-- Demo: Tables: Demonstrate using SameLine() between cells. (#3740)
-- Demo: Tables: Demonstrate altering CellPadding.y between rows. (#3740)
-- Demo: Custom Rendering: Demonstrate out-of-order rendering using ImDrawListSplitter.
-- Backends: SDL2,SDL3: added ImGui_ImplSDL2_InitForOther()/ImGui_ImplSDL3_InitForOther()
- for consistency (matching GLFW backend) and as most initialization paths don't actually
- need to care about rendering backend.
-- Examples: Emscripten+WebGPU: Fixed WGPUInstance creation process + use preferred
- framebuffer format. (#6640, #6748) [@smileorigin]

------------------------------------------------------------------------
- VERSION 1.89.8 (Released 2023-08-01)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.8
-
-Breaking changes:
-
-- IO: Obsoleted io.ClearInputCharacters() (added in 1.47) as it now ambiguous
- and often incorrect/misleading considering the existence of a higher-level
- input queue. This is automatically cleared by io.ClearInputsKeys(). (#4921)
-- ImDrawData: CmdLists[] array is now owned, changed from 'ImDrawList**' to
- 'ImVector'. Majority of users shouldn't be affected, but you
- cannot compare to NULL nor reassign manually anymore.
- Instead use AddDrawList(). Allocation count are identical. (#6406, #4879, #1878)
-
-Other changes:
-
-- Fonts: ImFontConfig::OversampleH now defaults to 2 instead of 3, since the
- quality increase is largely minimal.
-- Fonts, imgui_freetype: Added support to render OpenType SVG fonts using lunasvg.
- Requires enabling IMGUI_ENABLE_FREETYPE_LUNASVG along with IMGUI_ENABLE_FREETYPE,
- and providing headers/libraries for lunasvg. (#6591, #6607) [@sakiodre]
-- ImDrawData: CmdLists[] array is now an ImVector<> owned by ImDrawData rather
- than a pointer to internal state.
- - This makes it easier for user to create their own or append to an existing draw data.
- Added a ImDrawData::AddDrawList() helper function to do that. (#6406, #4879, #1878)
- - This makes it easier to perform a deep-swap instead of a deep-copy, as array
- ownership is now clear. (#6597, #6475, #6167, #5776, #5109, #4763, #3515, #1860)
- - Syntax and allocation count are otherwise identical.
-- Fixed CTRL+Tab dimming background assert when target window has a callback
- in the last ImDrawCmd. (#4857, #5937)
-- IsItemHovered: Fixed ImGuiHoveredFlags_ForTooltip for Keyboard/Gamepad navigation,
- got broken prior to 1.89.7 due to an unrelated change making flags conflict. (#6622, #1485)
-- InputText: Fixed a case where deactivation frame would write to underlying
- buffer or call CallbackResize although unnecessary, in a frame where the
- return value was false.
-- Tables: fixed GetContentRegionAvail().y report not taking account of lower cell
- padding or of using ImGuiTableFlags_NoHostExtendY. Not taking it into account
- would make the idiom of creating vertically bottom-aligned content (e.g. a child
- window) inside a table make the parent window erroneously have a scrollbar. (#6619)
-- Tables: fixed calculation of multi-instance shared decoration/scrollbar width of
- scrolling tables, to avoid flickering width variation when resizing down a table
- hosting a child window. (#5920, #6619)
-- Scrollbar: layout needs to take account of window border size, so a border size
- will slightly reduce scrollbar size. Generally we tried to make it that window
- border size has no incidence on layout but this can't work with thick borders. (#2522)
-- IO: Added io.ClearEventsQueue() to clear incoming inputs events. (#4921)
- May be useful in conjunction with io.ClearInputsKeys() if you need to clear
- both current inputs state and queued events (e.g. when using blocking native
- dialogs such as Windows's ::MessageBox() or ::GetOpenFileName()).
-- IO: Changed io.ClearInputsKeys() specs to also clear current frame character buffer
- (what now obsoleted io.ClearInputCharacters() did), as this is effectively the
- desirable behavior.
-- Misc: Added IMGUI_DISABLE_STB_SPRINTF_IMPLEMENTATION config macro to disable
- stb_sprintf implementation when using IMGUI_USE_STB_SPRINTF. (#6626) [@septag]
-- Misc: Avoid stb_textedit.h reincluding string.h while in a namespace, which
- messes up with building with Clang Modules. (#6653, #4791) [@JohelEGP]
-- Demo: Better showcase use of SetNextItemAllowOverlap(). (#6574, #6512, #3909, #517)
-- Demo: Showcase a few more InputText() flags.
-- Backends: Made all backends sources files support global IMGUI_DISABLE. (#6601)
-- Backends: GLFW: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used
- differently. User may set ImGuiConfigFlags_NoMouse if desired. (#5625, #6609) [@scorpion-26]
-- Backends: WebGPU: Update for changes in Dawn. (#6602, #6188) [@williamhCode]
-- Examples: Vulkan: Creating minimal descriptor pools to fit only what is needed by
- example. (#6642) [@SaschaWillem]

------------------------------------------------------------------------
- VERSION 1.89.7 (Released 2023-07-04)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.7
-
-Breaking changes:
-
-- Moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal.
- As the fields were added in 1.89 and expected to be left unchanged by most users, or only
- tweaked once during app initialisation, we are exceptionally accepting the breakage.
- Majority of users should not even notice.
-- Overlapping items: (#6512, #3909, #517)
- - Added 'SetNextItemAllowOverlap()' (called before an item) as a replacement for using
- 'SetItemAllowOverlap()' (called after an item). This is roughly equivalent to using the
- legacy 'SetItemAllowOverlap()' call (public API) + ImGuiButtonFlags_AllowOverlap (internal).
- - Obsoleted 'SetItemAllowOverlap()': it didn't and couldn't work reliably since 1.89 (2022-11-15),
- and relied on ambiguously defined design. Use 'SetNextItemAllowOverlap()' before item instead.
- - Selectable, TreeNode: When using ImGuiSelectableFlags_AllowOverlap/ImGuiTreeNodeFlags_AllowOverlap
- and holding item held, overlapping widgets won't appear as hovered. (#6512, #3909)
- While this fixes a common small visual issue, it also means that calling IsItemHovered()
- after a non-reactive elements - e.g. Text() - overlapping an active one may fail if you don't
- use IsItemHovered(ImGuiHoveredFlags_AllowWhenBlockedByActiveItem). (#6610)
- - Renamed 'ImGuiTreeNodeFlags_AllowItemOverlap' to 'ImGuiTreeNodeFlags_AllowOverlap'.
- - Renamed 'ImGuiSelectableFlags_AllowItemOverlap' to 'ImGuiSelectableFlags_AllowOverlap'
- - Kept redirecting enums (will obsolete).
-
-Other changes:
-
-- Tooltips/IsItemHovered() related changes:
- - Tooltips: Added SetItemTooltip() and BeginItemTooltip() functions.
- They are shortcuts for the common idiom of using IsItemHovered().
- - SetItemTooltip("Hello") == if (IsItemHovered(ImGuiHoveredFlags_Tooltip)) { SetTooltip("Hello"); }
- - BeginItemTooltip() == IsItemHovered(ImGuiHoveredFlags_Tooltip) && BeginTooltip()
- The newly added ImGuiHoveredFlags_Tooltip is meant to facilitate standardizing
- mouse hovering delays and rules for a given application.
- The previously common idiom of using 'if (IsItemHovered()) { SetTooltip(...); }'
- won't use delay or stationary test.
- - IsItemHovered: Added ImGuiHoveredFlags_Stationary to require mouse being
- stationary when hovering a new item. Added style.HoverStationaryDelay (~0.15 sec).
- Once the mouse has been stationary once the state is preserved for same item. (#1485)
- - IsItemHovered: Added ImGuiHoveredFlags_ForTooltip as a shortcut for pulling flags
- from style.HoverFlagsForTooltipMouse or style.HoverFlagsForTooltipNav depending
- on active inputs (#1485)
- - style.HoverFlagsForTooltipMouse defaults to 'ImGuiHoveredFlags_Stationary | ImGuiHoveredFlags_DelayShort'
- - style.HoverFlagsForTooltipNav defaults to 'ImGuiHoveredFlags_NoSharedDelay | ImGuiHoveredFlags_DelayNormal'.
- - Tooltips: Tweak default offset for non-drag and drop tooltips so underlying items
- isn't covered as much. (Match offset for drag and drop tooltips)
- - IsItemHovered: Tweaked default value of style.HoverDelayNormal from 0.30 to 0.40,
- Tweaked default value of style.HoverDelayShort from 0.10 to 0.15. (#1485)
- - IsItemHovered: Added ImGuiHoveredFlags_AllowWhenOverlappedByWindow to ignore window-overlap only.
- Option ImGuiHoveredFlags_AllowWhenOverlapped now expand into a combination of both
- _AllowWhenOverlappedByWindow + _AllowWhenOverlappedByItem, matching old behavior.
-- Overlapping items: (#6512, #3909, #517)
- - Most item types should now work with SetNextItemAllowOverlap(). (#6512, #3909, #517)
- - Fixed first frame of an overlap highlighting underlying item if previous frame didn't hover anything.
- - IsItemHovered: Changed to return false when querying an item using AllowOverlap mode which
- is being overlapped. Added ImGuiHoveredFlags_AllowWhenOverlappedByItem to opt-out. (#6512, #3909, #517)
-- IsWindowHovered: Added support for ImGuiHoveredFlags_Stationary.
-- IsWindowHovered, IsItemHovered: Assert when passed any unsupported flags.
-- Tables: Fixed a regression in 1.89.6 leading to the first column of tables with either
- ScrollX or ScrollY flags from being impossible to resize. (#6503)
-- CollapsingHeader/TreeNode: Fixed text padding when using _Framed+_Leaf flags. (#6549) [@BobbyAnguelov]
-- InputText: Fixed not returning true when buffer is cleared while using the
- ImGuiInputTextFlags_EscapeClearsAll flag. (#5688, #2620)
-- InputText: Fixed a crash on deactivating a ReadOnly buffer. (#6570, #6292, #4714)
-- InputText: ImGuiInputTextCallbackData::InsertChars() accept (NULL,NULL) range, in order to conform
- to common idioms (e.g. passing .data(), .data() + .size() from a null string). (#6565, #6566, #3615)
-- Combo: Made simple/legacy Combo() function not returns true when picking already selected item.
- This is consistent with other widgets. If you need something else, you can use BeginCombo(). (#1182)
-- Clipper: Rework inner logic to allow functioning with a zero-clear constructor.
- This is order to facilitate usage for language bindings (e.g cimgui or dear_binding)
- where user may not be calling a constructor manually. (#5856)
-- Drag and Drop: Apply default behavior of drag source not reporting itself as hovered
- at lower-level, so DragXXX, SliderXXX, InputXXX, Plot widgets are fulfilling it.
- (Behavior doesn't apply when ImGuiDragDropFlags_SourceNoDisableHover is set).
-- Modals: In the case of nested modal, made sure that focused or appearing windows are
- moved below the lowest blocking modal (rather than the highest one). (#4317)
-- GetKeyName(): Fixed assert with ImGuiMod_XXX values when IMGUI_DISABLE_OBSOLETE_KEYIO is set.
-- Debug Tools: Added 'io.ConfigDebugIniSettings' option to save .ini data with extra
- comments. Currently mainly for inspecting Docking .ini data, but makes saving slower.
-- Demo: Added more developed "Widgets->Tooltips" section. (#1485)
-- Backends: OpenGL3: Fixed support for glBindSampler() backup/restore on ES3. (#6375, #6508) [@jsm174]
-- Backends: OpenGL3: Fixed erroneous use glGetIntegerv(GL_CONTEXT_PROFILE_MASK) on contexts
- lower than 3.2. (#6539, #6333) [@krumelmonster]
-- Backends: Vulkan: Added optional support for VK_KHR_dynamic_rendering (Vulkan 1.3+) in the
- backend for applications using it. User needs to set 'init_info->UseDynamicRendering = true'
- and 'init_info->ColorAttachmentFormat'. RenderPass becomes unused. (#5446, #5037) [@spnda, @cmarcelo]
-- Backends: GLFW: Accept glfwGetTime() not returning a monotonically increasing value.
- This seems to happens on some Windows setup when peripherals disconnect, and is likely
- to also happen on browser+Emscripten. Matches similar 1.89.4 fix in SDL backend. (#6491)
-- Examples: Win32+OpenGL3: Changed DefWindowProc() to DefWindowProcW() to match other examples
- and support the example app being compiled without UNICODE. (#6516, #5725, #5961, #5975) [@yenixing]

- VERSION 1.89.6 (Released 2023-05-31)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.6
-
-Breaking changes:
-
-- Clipper: Commented out obsolete redirection constructor which was marked obsolete in 1.79:
- 'ImGuiListClipper(int items_count, float items_height)' --> Use 'ImGuiListClipper() + clipper.Begin()'.
-- Clipper: Renamed ForceDisplayRangeByIndices() to IncludeRangeByIndices(), kept
- inline redirection function (introduced in 1.86 and rarely used). (#6424, #3841)
-- Commented out obsolete/redirecting functions that were marked obsolete more than two years ago:
- - ListBoxHeader() -> use BeginListBox()
- - ListBoxFooter() -> use EndListBox()
- - Note how two variants of ListBoxHeader() existed. Check commented versions in imgui.h for refeence.
-- Backends: SDL_Renderer: Renamed 'imgui_impl_sdlrenderer.h/cpp' to 'imgui_impl_sdlrenderer2.h/cpp',
- in order to accomodate for upcoming SDL3 and change in its SDL_Renderer API. (#6286)
-- Backends: GLUT: Removed call to ImGui::NewFrame() from ImGui_ImplGLUT_NewFrame().
- It needs to be called from the main app loop, like with every other backends. (#6337) [@GereonV]
-
-Other changes:
-
-- Window: Fixed resizing from upper border when io.ConfigWindowsMoveFromTitleBarOnly is set. (#6390)
-- Tables: Fixed a small miscalculation in TableHeader() leading to an empty tooltip
- showing when a sorting column has no visible name. (#6342) [@lukaasm]
-- Tables: Fixed command merging when compiling with VS2013 (one array on stack was not
- initialized on VS2013. Unsure if due to a bug or UB/standard conformance). (#6377)
-- InputText: Avoid setting io.WantTextInputNextFrame during the deactivation frame.
- (#6341) [@lukaasm]
-- Drag, Sliders: if the format string doesn't contain any %, CTRL+Click to input text will
- use the default format specifier for the type. Allow display/input of raw value when using
- "enums" patterns (display label instead of value) + allow using when value is hidden. (#6405)
-- Nav: Record/restore preferred position on each given axis after a movement on that axis,
- then score movement on the other axis using this as a bias. This allows going up and down
- between e.g. a large header spanning horizontal space and three-ways-columns, landing
- on the same column as before.
-- Nav: Fixed navigation within tables/columns where item boundaries goes beyond columns limits,
- unclipped bounding boxes would interfere with other columns. (#2221) [@zzzyap, @ocornut]
-- Nav: Fixed CTRL+Tab into a root window with only childs with _NavFlattened flags
- erroneously initializing default nav layer to menu layer.
-- Menus: Fixed an issue when opening a menu hierarchy in a given menu-bar would allow
- opening another via simple hovering. (#3496, #4797)
-- Fonts: Fixed crash when merging fonts and the first font has no valid glyph. (#6446) [@JaedanC]
-- Fonts: Fixed crash when manually specifying an EllipsisChar that doesn't exist. (#6480)
-- Misc: Added ImVec2 unary minus operator. (#6368) [@Koostosh]
-- Debug Tools: Debug Log: Fixed not parsing 0xXXXXXXXX values for geo-locating on mouse
- hover hover when the identifier is at the end of the line. (#5855)
-- Debug Tools: Added 'io.ConfigDebugIgnoreFocusLoss' option to disable 'io.AddFocusEvent(false)'
- handling. May facilitate interactions with a debugger when focus loss leads to clearing
- inputs data. (#4388, #4921)
-- Backends: Clear bits sets io.BackendFlags on backend Shutdown(). (#6334, #6335] [@GereonV]
- Potentially this would facilitate switching runtime backend mid-session.
-- Backends: Win32: Added ImGui_ImplWin32_InitForOpenGL() to facilitate combining raw
- Win32/Winapi with OpenGL. (#3218)
-- Backends: OpenGL3: Restore front and back polygon mode separately when supported
- by context (Desktop 3.0, 3.1, or 3.2+ with compat bit). (#6333) [@GereonV]
-- Backends: OpenGL3: Support for glBindSampler() backup/restore on ES3. (#6375) [@jsm174]
-- Backends: SDL3: Fixed build on Emscripten/iOS/Android. (#6391) [@jo-codegirl]
-- Backends: SDLRenderer3: Added SDL_Renderer for SDL3 backend. (#6286) [@Carcons, @ocornut]
-- Examples: Added native Win32+OpenGL3 example. We don't recommend using this setup but we
- provide it for completeness. (#3218, #5170, #6086, #2772, #2600, #2359, #2022, #1553) [@learn-more]
-- Examples: Vulkan: Use integrated GPU if nothing else is available. (#6359) [@kimidaisuki22]
-- Examples: DX9, DX10, DX11: Queue framebuffer resize instead of processing in WM_SIZE,
- as some drivers tends to only cleanup after existing the native resize modal loop. (#6374)
-- Examples: Added SDL3+SDL_Renderer example. (#6286)
-- Examples: Updated all Visual Studio projects and batches to use /utf-8 argument.

- VERSION 1.89.5 (Released 2023-04-13)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.5
-
-Other changes:
-
-- InputText: Reworked prev/next-word behavior to more closely match Visual Studio
- text editor. Include '.' as a delimiter and alter varying subtle behavior with how
- blanks and separators are treated when skipping words. (#6067) [@ajweeks]
-- InputText: Fixed a tricky edge case, ensuring value is always written back on the
- frame where IsItemDeactivated() returns true, in order to allow usage without user
- retaining underlying data. While we don't really want to encourage user not retaining
- underlying data, in the absence of a "late commit" behavior/flag we understand it may
- be desirable to take advantage of this trick. (#4714)
-- Drag, Sliders: Fixed parsing of text input when '+' or '#' format flags are used
- in the format string. (#6259) [@idbrii]
-- Nav: Made Ctrl+Tab/Ctrl+Shift+Tab windowing register ownership to held modifier so
- it doesn't interfere with other code when remapping those actions. (#4828, #3255, #5641)
-- Nav: Made PageUp/PageDown/Home/End navigation also scroll parent windows when
- necessary to make the target location fully visible (same as e.g. arrow keys).
-- ColorEdit: Fixed shading of S/V triangle in Hue Wheel mode. (#5200, #6254) [@jamesthomasgriffin]
-- TabBar: Tab-bars with ImGuiTabBarFlags_FittingPolicyScroll can be scrolled with
- horizontal mouse-wheel (or Shift + WheelY). (#2702)
-- Rendering: Using adaptive tessellation for RadioButton, ColorEdit preview circles,
- Windows Close and Collapse Buttons.
-- ButtonBehavior: Fixed an edge case where changing widget type/behavior while active
- and using same id could lead to an assert. (#6304)
-- Misc: Fixed ImVec2 operator[] violating aliasing rules causing issue with Intel C++
- compiler. (#6272) [@BayesBug]
-- IO: Input queue trickling adjustment for touch screens. (#2702, #4921)
- This fixes single-tapping to move simulated mouse and immediately click on a widget
- that is using the ImGuiButtonFlags_AllowItemOverlap policy.
- - This only works if the backend can distinguish TouchScreen vs Mouse.
- See 'Demo->Tools->Metrics->Inputs->Mouse Source' to verify.
- - Fixed tapping on BeginTabItem() on a touch-screen. (#2702)
- - Fixed tapping on CollapsingHeader() with a close button on a touch-screen.
- - Fixed tapping on TreeNode() using ImGuiTreeNodeFlags_AllowItemOverlap on a touch-screen.
- - Fixed tapping on Selectable() using ImGuiSelectableFlags_AllowItemOverlap on a touch-screen.
- - Fixed tapping on TableHeader() on a touch-screen.
-- IO: Added io.AddMouseSourceEvent() and ImGuiMouseSource enum. This is to allow backend to
- specify actual event source between Mouse/TouchScreen/Pen. (#2702, #2334, #2372, #3453, #5693)
-- IO: Fixed support for calling io.AddXXXX functions from inactive context (wrongly
- advertised as supported in 1.89.4). (#6199, #6256, #5856) [@cfillion]
-- Backends: OpenGL3: Fixed GL loader crash when GL_VERSION returns NULL. (#6154, #4445, #3530)
-- Backends: OpenGL3: Properly restoring "no shader program bound" if it was the case prior to
- running the rendering function. (#6267, #6220, #6224) [@BrunoLevy]
-- Backends: Win32: Added support for io.AddMouseSourceEvent() to discriminate Mouse/TouchScreen/Pen. (#2334, #2702)
-- Backends: SDL2/SDL3: Added support for io.AddMouseSourceEvent() to discriminate Mouse/TouchScreen.
- This is relying on SDL passing SDL_TOUCH_MOUSEID in the event's 'which' field. (#2334, #2702)
-- Backends: SDL2/SDL3: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they actually
- block text input input and don't only pertain to IME. It's unclear exactly what their relation
- is to other IME function such as SDL_SetTextInputRect(). (#6306, #6071, #1953)
-- Backends: GLFW: Added support on Win32 only for io.AddMouseSourceEvent() to discriminate
- Mouse/TouchScreen/Pen. (#2334, #2702)
-- Backends: GLFW: Fixed key modifiers handling on secondary viewports. (#6248, #6034) [@aiekick]
-- Backends: Android: Added support for io.AddMouseSourceEvent() to discriminate Mouse/TouchScreen/Pen.
- (#6315) [@PathogenDavid]
-- Backends: OSX: Added support for io.AddMouseSourceEvent() to discriminate Mouse/Pen.
- (#6314) [@PathogenDavid]
-- Backends: WebGPU: Align buffers. Use WGSL shaders instead of SPIR-V. Add gamma uniform. (#6188) [@eliemichel]
-- Backends: WebGPU: Reorganized to store data in io.BackendRendererUserData like other backends.
-- Examples: Vulkan: Fixed validation errors with newer VulkanSDK by explicitly querying and enabling
- "VK_KHR_get_physical_device_properties2", "VK_KHR_portability_enumeration", and
- VK_INSTANCE_CREATE_ENUMERATE_PORTABILITY_BIT_KHR. (#6109, #6172, #6101)
-- Examples: Windows: Added 'misc/debuggers/imgui.natstepfilter' file to all Visual Studio projects,
- now that VS 2022 17.6 Preview 2 support adding Debug Step Filter spec files into projects.
-- Examples: SDL3: Updated for latest WIP SDL3 branch. (#6243)
-- TestSuite: Added variety of new regression tests and improved/amended existing ones
- in imgui_test_engine/ repo. [@PathogenDavid, @ocornut]

------------------------------------------------------------------------
- VERSION 1.89.4 (Released 2023-03-14)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.4
-
-Breaking Changes:
-
-- Renamed PushAllowKeyboardFocus()/PopAllowKeyboardFocus() to PushTabStop()/PopTabStop().
- Kept inline redirection functions (will obsolete).
-- Moved the optional "courtesy maths operators" implementation from imgui_internal.h in imgui.h.
- Even though we encourage using your own maths types and operators by setting up IM_VEC2_CLASS_EXTRA,
- it has been frequently requested by people to use our own. We had an opt-in define which was
- previously fulfilled by imgui_internal.h. It is now fulfilled by imgui.h. (#6164, #6137, #5966, #2832)
- OK: #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui.h" / #include "imgui_internal.h"
- Error: #include "imgui.h" / #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui_internal.h"
- Added a dedicated compile-time check message to help diagnose this.
-- Tooltips: Added 'bool' return value to BeginTooltip() for API consistency.
- Please only submit contents and call EndTooltip() if BeginTooltip() returns true.
- In reality the function will _currently_ always return true, but further changes down the
- line may change this, best to clarify API sooner. Updated demo code accordingly.
-- Commented out redirecting enums/functions names that were marked obsolete two years ago:
- - ImGuiSliderFlags_ClampOnInput -> use ImGuiSliderFlags_AlwaysClamp
- - ImGuiInputTextFlags_AlwaysInsertMode -> use ImGuiInputTextFlags_AlwaysOverwrite
- - ImDrawList::AddBezierCurve() -> use ImDrawList::AddBezierCubic()
- - ImDrawList::PathBezierCurveTo() -> use ImDrawList::PathBezierCubicCurveTo()
-
-Other changes:
-
-- Nav: Tabbing now cycles through all items when ImGuiConfigFlags_NavEnableKeyboard is set.
- (#3092, #5759, #787)
- While this was generally desired and requested by many, note that its addition means
- that some types of UI may become more fastidious to use TAB key with, if the navigation
- cursor cycles through too many items. You can mark items items as not tab-spottable:
- - Public API: PushTabStop(false) / PopTabStop()
- - Internal: PushItemFlag(ImGuiItemFlags_NoTabStop, true);
- - Internal: Directly pass ImGuiItemFlags_NoTabStop to ItemAdd() for custom widgets.
-- Nav: Tabbing/Shift-Tabbing can more reliably be used to step out of an item that is not
- tab-stoppable. (#3092, #5759, #787)
-- Nav: Made Enter key submit the same type of Activation event as Space key,
- allowing to press buttons with Enter. (#5606)
- (Enter emulates a "prefer text input" activation vs.
- Space emulates a "prefer tweak" activation which is to closer to gamepad controls).
-- Nav: Fixed an issue with Gamepad navigation when the movement lead to a scroll and
- frame time > repeat rate. Triggering a new move request on the same frame as a move
- result lead to an incorrect calculation and loss of navigation id. (#6171)
-- Nav: Fixed SetItemDefaultFocus() from not scrolling when item is partially visible.
- (#2814, #2812) [@DomGries]
-- Tables: Fixed an issue where user's Y cursor movement within a hidden column would
- have side-effects.
-- IO: Lifted constraint to call io.AddEventXXX functions from current context. (#4921, #5856, #6199)
-- InputText: Fixed not being able to use CTRL+Tab while an InputText() using Tab
- for completion or text data is active (regression from 1.89).
-- Drag and Drop: Fixed handling of overlapping targets when smaller one is submitted
- before and can accept the same data type. (#6183).
-- Drag and Drop: Clear drag and drop state as soon as delivery is accepted in order to
- avoid interferences. (#5817, #6183) [@DimaKoltun]
-- Debug Tools: Added io.ConfigDebugBeginReturnValueOnce / io.ConfigDebugBeginReturnValueLoop
- options to simulate Begin/BeginChild returning false to facilitate debugging user behavior.
-- Demo: Updated to test return value of BeginTooltip().
-- Backends: OpenGL3: Fixed restoration of a potentially deleted OpenGL program. If an active
- program was pending deletion, attempting to restore it would error. (#6220, #6224) [@Cyphall]
-- Backends: Win32: Use WM_NCMOUSEMOVE / WM_NCMOUSELEAVE to track mouse positions over
- non-client area (e.g. OS decorations) when app is not focused. (#6045, #6162)
-- Backends: SDL2, SDL3: Accept SDL_GetPerformanceCounter() not returning a monotonically
- increasing value. (#6189, #6114, #3644) [@adamkewley]
-- Backends: GLFW: Avoid using glfwGetError() and glfwGetGamepadState() on Emscripten, which
- recently updated its GLFW emulation layer to GLFW 3.3 without supporting those. (#6240)
-- Examples: Android: Fixed example build for Gradle 8. (#6229, #6227) [@duddel]
-- Examples: Updated all examples application to enable ImGuiConfigFlags_NavEnableKeyboard
- and ImGuiConfigFlags_NavEnableGamepad by default. (#787)
-- Internals: Misc tweaks to facilitate applying an explicit-context patch. (#5856) [@Dragnalith]

- VERSION 1.89.3 (Released 2023-02-14)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.3
-
-Breaking Changes:
-
-- Backends+Examples: SDL2: renamed all unnumbered references to "sdl" to "sdl2".
- This is in prevision for the future release of SDL3 and its associated backend. (#6146)
- - imgui_impl_sdl.cpp -> imgui_impl_sdl2.cpp
- - imgui_impl_sdl.h -> imgui_impl_sdl2.h
- - example_sdl_xxxx/ -> example_sdl2_xxxx/ (folders and projects)
-
-Other changes:
-
-- SeparatorText(): Added SeparatorText() widget. (#1643) [@phed, @ocornut]
- - Added to style: float SeparatorTextBorderSize.
- - Added to style: ImVec2 SeparatorTextAlign, SeparatorTextPadding.
-- Tables: Raised max Columns count from 64 to 512. (#6094, #5305, #4876, #3572)
- The previous limit was due to using 64-bit integers but we moved to bits-array
- and tweaked the system enough to ensure no performance loss.
-- Tables: Solved an ID conflict issue with multiple-instances of a same table,
- due to how unique table instance id was generated. (#6140) [@ocornut, @rodrigorc]
-- Inputs, Scrolling: Made horizontal scroll wheel and horizontal scroll direction consistent
- across backends/os. (#4019, #6096, #1463) [@PathogenDavid, @ocornut, @rokups]
- - Clarified that 'wheel_y > 0.0f' scrolls Up, 'wheel_y > 0.0f' scrolls Down.
- Clarified that 'wheel_x > 0.0f' scrolls Left, 'wheel_x > 0.0f' scrolls Right.
- - Backends: Fixed horizontal scroll direction for Win32 and SDL backends. (#4019)
- - Shift+WheelY support on non-OSX machines was already correct. (#2424, #1463)
- (whereas on OSX machines Shift+WheelY turns into WheelX at the OS level).
- - If you use a custom backend, you should verify horizontal wheel direction.
- - Axises are flipped by OSX for mouse & touch-pad when 'Natural Scrolling' is on.
- - Axises are flipped by Windows for touch-pad when 'Settings->Touchpad->Down motion scrolls up' is on.
- - You can use 'Demo->Tools->Debug Log->IO" to visualize values submitted to Dear ImGui.
- - Known issues remaining with Emscripten:
- - The magnitude of wheeling values on Emscripten was improved but isn't perfect. (#6096)
- - When running the Emscripten app on a Mac with a mouse, SHIFT+WheelY doesn't turn into WheelX.
- This is because we don't know that we are running on Mac and apply our own Shift+swapping
- on top of OSX' own swapping, so wheel axises are swapped twice. Emscripten apps may need
- to find a way to detect this and set io.ConfigMacOSXBehaviors manually (if you know a way
- let us know!), or offer the "OSX-style behavior" option to their user.
-- Window: Avoid rendering shapes for hidden resize grips.
-- Text: Fixed layouting of wrapped-text block skipping successive empty lines,
- regression from the fix in 1.89.2. (#5720, #5919)
-- Text: Fixed clipping of single-character "..." ellipsis (U+2026 or U+0085) when font
- is scaled. Scaling wasn't taken into account, leading to ellipsis character straying
- slightly out of its expected boundaries. (#2775)
-- Text: Tweaked rendering of three-dots "..." ellipsis variant. (#2775, #4269)
-- InputText: Added support for Ctrl+Delete to delete up to end-of-word. (#6067) [@ajweeks]
- (Not adding Super+Delete to delete to up to end-of-line on OSX, as OSX doesn't have it)
-- InputText: On OSX, inhibit usage of Alt key to toggle menu when active (used for work skip).
-- Menus: Fixed layout of MenuItem()/BeginMenu() when label contains a '\n'. (#6116) [@imkcy9]
-- ColorEdit, ColorPicker: Fixed hue/saturation preservation logic from interfering with
- the displayed value (but not stored value) of others widgets instances. (#6155)
-- PlotHistogram, PlotLines: Passing negative sizes honor alignment like other widgets.
-- Combo: Allow SetNextWindowSize() to alter combo popup size. (#6130)
-- Fonts: Assert that in each GlyphRanges[] pairs first is <= second.
-- ImDrawList: Added missing early-out in AddPolyline() and AddConvexPolyFilled() when
- color alpha is zero.
-- Misc: Most text functions treat "%s" as a shortcut to no-formatting. (#3466)
-- Misc: Tolerate zero delta-time under Emscripten as backends are imprecise in their
- values for io.DeltaTime, and browser features such as "privacy.resistFingerprinting=true"
- can exacerbate that. (#6114, #3644)
-- Backends: OSX: Fixed scroll/wheel scaling for devices emitting events with
- hasPreciseScrollingDeltas==false (e.g. non-Apple mices).
-- Backends: Win32: flipping WM_MOUSEHWHEEL horizontal value to match other backends and
- offer consistent horizontal scrolling direction. (#4019)
-- Backends: SDL2: flipping SDL_MOUSEWHEEL horizontal value to match other backends and
- offer consistent horizontal scrolling direction. (#4019)
-- Backends: SDL2: Removed SDL_MOUSEWHEEL value clamping. (#4019, #6096, #6081)
-- Backends: SDL2: Added support for SDL 2.0.18+ preciseX/preciseY mouse wheel data
- for smooth scrolling as reported by SDL. (#4019, #6096)
-- Backends: SDL2: Avoid calling SDL_SetCursor() when cursor has not changed, as the function
- is surprisingly costly on Mac with latest SDL (already fixed in SDL latest trunk). (#6113)
-- Backends: SDL2: Implement IME handler to call SDL_SetTextInputRect()/SDL_StartTextInput().
- It will only works with SDL 2.0.18+ if your code calls 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1")'
- prior to calling SDL_CreateWindow(). Updated all examples accordingly. (#6071, #1953)
-- Backends: SDL3: Added experimental imgui_impl_sdl3.cpp backend. (#6146) [@dovker, @ocornut]
- SDL 3.0.0 has not yet been released, so it is possible that its specs/api will change before
- release. This backend is provided as a convenience for early adopters etc. We don't recommend
- switching to SDL3 before it is released.
-- Backends: GLFW: Registering custom low-level mouse wheel handler to get more accurate
- scrolling impulses on Emscripten. (#4019, #6096) [@ocornut, @wolfpld, @tolopolarity]
-- Backends: GLFW: Added ImGui_ImplGlfw_SetCallbacksChainForAllWindows() to instruct backend
- to chain callbacks even for secondary viewports/windows. User callbacks may need to test
- the 'window' parameter. (#6142)
-- Backends: OpenGL3: Fixed GL loader compatibility with 2.x profiles. (#6154, #4445, #3530) [@grauw]
-- Backends: WebGPU: Fixed building for latest WebGPU specs (remove implicit layout generation).
- (#6117, #4116, #3632) [@tonygrue, @bfierz]
-- Examples: refactored SDL2+GL and GLFW+GL examples to compile with Emscripten.
- (#2492, #2494, #3699, #3705) [@ocornut, @nicolasnoble]
- The dedicated example_emscripten_opengl3/ has been removed.
-- Examples: Added SDL3+GL experimental example. (#6146)
-- Examples: Win32: Fixed examples using RegisterClassW() since 1.89 to also call
- DefWindowProcW() instead of DefWindowProc() so that title text are correctly converted
- when application is compiled without /DUNICODE. (#5725, #5961, #5975) [@markreidvfx]
-- Examples: SDL2+SDL_Renderer: Added call to SDL_RenderSetScale() to fix display on a
- Retina display (albeit lower-res as our other unmodified examples). (#6121, #6065, #5931).

- VERSION 1.89.2 (Released 2023-01-05)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.2
-
-All changes:
-
-- Tables, Nav, Scrolling: fixed scrolling functions and focus tracking with frozen rows and
- frozen columns. Windows now have a better understanding of outer/inner decoration sizes,
- which should later lead us toward more flexible uses of menu/status bars. (#5143, #3692)
-- Tables, Nav: frozen columns are not part of menu layer and can be crossed over. (#5143, #3692)
-- Tables, Columns: fixed cases where empty columns may lead to empty ImDrawCmd. (#4857, #5937)
-- Tables: fixed matching width of synchronized tables (multiple tables with same id) when only
- some instances have a vertical scrollbar and not all. (#5920)
-- Fixed cases where CTRL+Tab or Modal can occasionally lead to the creation of ImDrawCmd with
- zero triangles, which would makes the render loop of some backends assert (e.g. Metal with
- debugging, Allegro). (#4857, #5937)
-- Inputs, IO: reworked ImGuiMod_Shortcut to redirect to Ctrl/Super at runtime instead of
- compile-time, being consistent with our support for io.ConfigMacOSXBehaviors and making it
- easier for bindings generators to process that value. (#5923, #456)
-- Inputs, Scrolling: better selection of scrolling window when hovering nested windows
- and when backend/OS is emitting dual-axis wheeling inputs (typically touch pads on macOS).
- We now select a primary axis based on recent events, and select a target window based on it.
- We expect this behavior to be further improved/tweaked. (#3795, #4559) [@ocornut, @folays]
-- InputText: fixed cursor navigation when pressing Up Arrow on the last character of a
- multiline buffer which doesn't end with a carriage return. (#6000)
-- Text: fixed layouting of wrapped-text block when the last source line is above the
- clipping region. Regression added in 1.89. (#5720, #5919)
-- Misc: added GetItemID() in public API. It is not often expected that you would use this,
- but it is useful for Shortcut() and upcoming owner-aware input functions which wants to
- be implemented with public API.
-- Fonts: imgui_freetype: fixed a packing issue which in some occurrences would prevent large
- amount of glyphs from being packed correctly. (#5788, #5829)
-- Fonts: added a 'void* UserData' field in ImFontAtlas, as a convenience for use by
- applications using multiple font atlases.
-- Demo: simplified "Inputs" section, moved contents to Metrics->Inputs.
-- Debug Tools: Metrics: added "Inputs" section, moved from Demo for consistency.
-- Misc: fixed parameters to IMGUI_DEBUG_LOG() not being dead-stripped when building
- with IMGUI_DISABLE_DEBUG_TOOLS is used. (#5901) [@Teselka]
-- Misc: fixed compile-time detection of SSE features on MSVC 32-bits builds. (#5943) [@TheMostDiligent]
-- Examples: DirectX10, DirectX11: try WARP software driver if hardware driver is not available. (#5924, #5562)
-- Backends: GLFW: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), which
- could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW,
- turns out they are faulty in this specific situation. (#6034)
-- Backends: Allegro5: restoring using al_draw_indexed_prim() when Allegro version is >= 5.2.5. (#5937) [@Espyo]
-- Backends: Vulkan: Fixed sampler passed to ImGui_ImplVulkan_AddTexture() not being honored as we were using
- an immutable sampler. (#5502, #6001, #914) [@martin-ejdestig, @rytisss]

- VERSION 1.89.1 (Released 2022-11-24)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.1
-
-Other changes:
-
-- Scrolling, Focus: fixed SetKeyboardFocusHere()/SetItemDefaultFocus() during a window-appearing
- frame (and associated lower-level functions e.g. ScrollToRectEx()) from not centering item. (#5902)
-- Inputs: fixed moving a window or drag and dropping from preventing input-owner-unaware code
- from accessing keys. (#5888, #4921, #456)
-- Inputs: fixed moving a window or drag and dropping from capturing mods. (#5888, #4921, #456)
-- Layout: fixed End()/EndChild() incorrectly asserting if users manipulates cursor position
- inside a collapsed/culled window and IMGUI_DISABLE_OBSOLETE_FUNCTIONS is enabled. (#5548, #5911)
-- Combo: fixed selected item (marked with SetItemDefaultFocus()) from not being centered when
- the combo window initially appears. (#5902).
-- ColorEdit: fixed label overlapping when using style.ColorButtonPosition == ImGuiDir_Left to
- move the color button on the left side (regression introduced in 1.88 WIP 2022/02/28). (#5912)
-- Drag and Drop: fixed GetDragDropPayload() returning a non-NULL value if a drag source is
- active but a payload hasn't been submitted yet. This is convenient to detect new payload
- from within a drag source handler. (#5910, #143)
-- Backends: GLFW: cancel out errors emitted by glfwGetKeyName() when a name is missing. (#5908)
-- Backends: WebGPU: fixed validation error with default depth buffer settings. (#5869, #5914) [@kdchambers]

-
------------------------------------------------------------------------
- VERSION 1.89 (Released 2022-11-15)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89
-
-Breaking changes:
-
-- Layout: Obsoleted using SetCursorPos()/SetCursorScreenPos() to extend parent window/cell boundaries. (#5548)
- This relates to when moving the cursor position beyond current boundaries WITHOUT submitting an item.
- - Previously this would make the window content size ~200x200:
- Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End();
- - Instead, please submit an item:
- Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End();
- - Alternative:
- Begin(...) + Dummy(ImVec2(200,200)) + End();
- Content size is now only extended when submitting an item.
- With '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will now be detected and assert.
- Without '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will silently be fixed until we obsolete it.
- (This incorrect pattern has been mentioned or suggested in: #4510, #3355, #1760, #1490, #4152, #150,
- threads have been amended to refer to this issue).
-- Inputs: ImGuiKey is now a typed enum, allowing ImGuiKey_XXX symbols to be named in debuggers. (#4921)
- This will require uses of legacy backend-dependent indices to be casted, e.g.
- - with imgui_impl_glfw: IsKeyPressed(GLFW_KEY_A) -> IsKeyPressed((ImGuiKey)GLFW_KEY_A);
- - with imgui_impl_win32: IsKeyPressed('A') -> IsKeyPressed((ImGuiKey)'A')
- - etc. however if you are upgrading code you might as well use the backend-agnostic IsKeyPressed(ImGuiKey_A) now.
-- Renamed and merged keyboard modifiers key enums and flags into a same set: (#4921, #456)
- - ImGuiKey_ModCtrl and ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl
- - ImGuiKey_ModShift and ImGuiModFlags_Shift -> ImGuiMod_Shift
- - ImGuiKey_ModAlt and ImGuiModFlags_Alt -> ImGuiMod_Alt
- - ImGuiKey_ModSuper and ImGuiModFlags_Super -> ImGuiMod_Super
- Kept inline redirection enums (will obsolete).
- This change simplifies a few things, reduces confusion, and will facilitate upcoming
- shortcut/input ownership apis.
- - The ImGuiKey_ModXXX were introduced in 1.87 and mostly used by backends.
- - The ImGuiModFlags_XXX have been exposed in imgui.h but not really used by any public api,
- only by third-party extensions. They were however subject to a recent rename
- (ImGuiKeyModFlags_XXX -> ImGuiModFlags_XXX) and we are exceptionally commenting out
- the older ImGuiKeyModFlags_XXX names ahead of obsolescence schedule to reduce confusion
- and because they were not meant to be used anyway.
-- Removed io.NavInputs[] and ImGuiNavInput enum that were used to feed gamepad inputs.
- Basically 1.87 already obsoleted them from the backend's point of view, but internally
- our navigation code still used this array and enum, so they were still present.
- Not anymore! (#4921, #4858, #787, #1599, #323)
- Transition guide:
- - Official backends from 1.87+ -> no issue.
- - Official backends from 1.60 to 1.86 -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need updating!
- - Custom backends not writing to io.NavInputs[] -> no issue.
- - Custom backends writing to io.NavInputs[] -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need fixing!
- - TL;DR: Backends should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values instead of filling io.NavInput[].
- The ImGuiNavInput enum was essentially 1.60's attempt to combine keyboard and gamepad inputs with named
- semantic, but the additional indirection and copy added complexity and got in the way of other
- incoming work. User's code (other than backends) should not be affected, unless you have custom
- widgets intercepting navigation events via the named enums (in which case you can upgrade your code).
-- DragInt()/SliderInt(): Removed runtime patching of invalid "%f"/"%.0f" types of format strings.
- This was obsoleted in 1.61 (May 2018). See 1.61 changelog for details.
-- Changed signature of ImageButton() function: (#5533, #4471, #2464, #1390)
- - Added 'const char* str_id' parameter + removed 'int frame_padding = -1' parameter.
- - Old signature: bool ImageButton(ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), int frame_padding = -1, ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));
- - used the ImTextureID value to create an ID. This was inconsistent with other functions, led to ID conflicts, and caused problems with engines using transient ImTextureID values.
- - had a FramePadding override which was inconsistent with other functions and made the already-long signature even longer.
- - New signature: bool ImageButton(const char* str_id, ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));
- - requires an explicit identifier. You may still use e.g. PushID() calls and then pass an empty identifier.
- - always uses style.FramePadding for padding, to be consistent with other buttons. You may use PushStyleVar() to alter this.
- - As always we are keeping a redirection function available (will obsolete later).
-- Removed the bizarre legacy default argument for 'TreePush(const void* ptr = NULL)'. (#1057)
- Must always pass a pointer value explicitly, NULL/nullptr is ok but require cast, e.g. TreePush((void*)nullptr);
- If you used TreePush() replace with TreePush((void*)NULL);
-- Removed support for 1.42-era IMGUI_DISABLE_INCLUDE_IMCONFIG_H / IMGUI_INCLUDE_IMCONFIG_H. (#255)
- They only made sense before we could use IMGUI_USER_CONFIG.
-
-Other Changes:
-
-- Popups & Modals: fixed nested Begin() inside a popup being erroneously input-inhibited.
- While it is unusual, you can nest a Begin() inside a popup or modal, it is occasionally
- useful to achieve certain things (e.g. to implement suggestion popups #718, #4461).
-- Inputs: Standard widgets now claim for key/button ownership and test for them.
- - Fixes scenario where e.g. a Popup with a Selectable() reacting on mouse down
- (e.g. double click) closes, and behind it is another window with an item reacting
- on mouse up. Previously this would lead to both items reacting, now the item in the
- window behind won't react on the mouse up since the mouse button ownership has already
- been claimed earlier.
- - Internals: There are MANY more aspects to this changes. Added experimental/internal APIs
- to allow handling input/shorting routing and key ownership. Things will be moved into
- public APIs over time. For now this release is a way to test the solidity of underlying
- systems while letting early adopters adopters toy with internals.
- (#456, #2637, #2620, #2891, #3370, #3724, #4828, #5108, #5242, #5641)
-- Scrolling: Tweak mouse-wheel locked window timer so it is shorter but also gets reset
- whenever scrolling again. Modulate for small (sub-pixel) amounts. (#2604)
-- Scrolling: Mitigated issue where multi-axis mouse-wheel inputs (usually from touch pad
- events) are incorrectly locking scrolling in a parent window. (#4559, #3795, #2604)
-- Scrolling: Exposed SetNextWindowScroll() in public API. Useful to remove a scrolling
- delay in some situations where e.g. windows need to be synched. (#1526)
-- InputText: added experimental io.ConfigInputTextEnterKeepActive feature to make pressing
- Enter keep the input active and select all text.
-- InputText: numerical fields automatically accept full-width characters (U+FF01..U+FF5E)
- by converting them to half-width (U+0021..U+007E).
-- InputText: added ImGuiInputTextFlags_EscapeClearsAll flag: first press on Escape clears
- text if any, second press deactivate the InputText(). (#5688, #2620)
-- InputText: added support for shift+click style selection. (#5619) [@procedural]
-- InputText: clarified that callbacks cannot modify buffer when using the ReadOnly flag.
-- InputText: fixed minor one-frame selection glitch when reverting with Escape.
-- ColorEdit3: fixed id collision leading to an assertion. (#5707)
-- IsItemHovered: Added ImGuiHoveredFlags_DelayNormal and ImGuiHoveredFlags_DelayShort flags,
- allowing to introduce a shared delay for tooltip idioms. The delays are respectively
- io.HoverDelayNormal (default to 0.30f) and io.HoverDelayShort (default to 0.10f). (#1485)
-- IsItemHovered: Added ImGuiHoveredFlags_NoSharedDelay to disable sharing delays between items,
- so moving from one item to a nearby one will requires delay to elapse again. (#1485)
-- Tables: activating an ID (e.g. clicking button inside) column doesn't prevent columns
- output flags from having ImGuiTableColumnFlags_IsHovered set. (#2957)
-- Tables,Columns: fixed a layout issue where SameLine() prior to a row change would set the
- next row in such state where subsequent SameLine() would move back to previous row.
-- Tabs: Fixed a crash when closing multiple windows (possible with docking only) with an
- appended TabItemButton(). (#5515, #3291) [@rokups]
-- Tabs: Fixed shrinking policy leading to infinite loops when fed unrounded tab widths. (#5652)
-- Tabs: Fixed shrinking policy sometimes erroneously making right-most tabs stray a little out
- bar boundaries (bug in 1.88). (#5652).
-- Tabs: Enforcing minimum size of 1.0f, fixed asserting on zero-tab widths. (#5572)
-- Window: Fixed a potential crash when appending to a child window. (#5515, #3496, #4797) [@rokups]
-- Window: Fixed an issue where uncollapsed a window would show a scrollbar for a frame.
-- Window: Auto-fit size takes account of work rectangle (menu bars eating from viewport). (#5843)
-- Window: Fixed position not being clamped while auto-resizing (fixes appearing windows without
- .ini data from moving for a frame when using io.ConfigWindowsMoveFromTitleBarOnly). (#5843)
-- IO: Added ImGuiMod_Shortcut which is ImGuiMod_Super on Mac and ImGuiMod_Ctrl otherwise. (#456)
-- IO: Added ImGuiKey_MouseXXX aliases for mouse buttons/wheel so all operations done on ImGuiKey
- can apply to mouse data as well. (#4921)
-- IO: Filter duplicate input events during the AddXXX() calls. (#5599, #4921)
-- IO: Fixed AddFocusEvent(false) to also clear MouseDown[] state. (#4921)
-- Menus: Fixed incorrect sub-menu parent association when opening a menu by closing another.
- Among other things, it would accidentally break part of the closing heuristic logic when moving
- towards a sub-menu. (#2517, #5614). [@rokups]
-- Menus: Fixed gaps in closing logic which would make child-menu erroneously close when crossing
- the gap between a menu item inside a window and a child-menu in a secondary viewport. (#5614)
-- Menus: Fixed using IsItemHovered()/IsItemClicked() on BeginMenu(). (#5775)
-- Menus, Popups: Experimental fix for issue where clicking on an open BeginMenu() item called from
- a window which is neither a popup neither a menu used to incorrectly close and reopen the menu
- (the fix may have side-effect and is labelld as experimental as we may need to revert). (#5775)
-- Menus, Nav: Fixed keyboard/gamepad navigation occasionally erroneously landing on menu-item
- in parent window when the parent is not a popup. (#5730)
-- Menus, Nav: Fixed not being able to close a menu with Left arrow when parent is not a popup. (#5730)
-- Menus, Nav: Fixed using left/right navigation when appending to an existing menu (multiple
- BeginMenu() call with same names). (#1207)
-- Menus: Fixed a one-frame issue where SetNextWindowXXX data are not consumed by a BeginMenu()
- returning false.
-- Nav: Fixed moving/resizing window with gamepad or keyboard when running at very high framerate.
-- Nav: Pressing Space/GamepadFaceDown on a repeating button uses the same repeating rate as a mouse hold.
-- Nav: Fixed an issue opening a menu with Right key from a non-menu window.
-- Text: Fixed wrapped-text not doing a fast-forward on lines above the clipping region,
- which would result in an abnormal number of vertices created (was slower and more likely to
- asserts with 16-bits ImDrawVtx). (#5720)
-- Fonts: Added GetGlyphRangesGreek() helper for Greek & Coptic glyph range. (#5676, #5727) [@azonenberg]
-- ImDrawList: Not using alloca() anymore, lift single polygon size limits. (#5704, #1811)
- - Note: now using a temporary buffer stored in ImDrawListSharedData.
- This change made it more visible than you cannot append to multiple ImDrawList from multiple
- threads if they share the same ImDrawListSharedData. Previously it was a little more likely
- for this to "accidentally" work, but was already incorrect. (#6167)
-- Platform IME: [Windows] Removed call to ImmAssociateContextEx() leading to freeze on some setups.
- (#2589, #5535, #5264, #4972)
-- Misc: better error reporting for PopStyleColor()/PopStyleVar() + easier to recover. (#1651)
-- Misc: io.Framerate moving average now converge in 60 frames instead of 120. (#5236, #4138)
-- Debug Tools: Debug Log: Visually locate items when hovering a 0xXXXXXXXX value. (#5855)
-- Debug Tools: Debug Log: Added 'IO' and 'Clipper' events logging. (#5855)
-- Debug Tools: Metrics: Visually locate items when hovering a 0xXXXXXXXX value (in most places).
-- Debug Tools: Item Picker: Mouse button can be changed by holding Ctrl+Shift, making it easier
- to use the Item Picker in e.g. menus. (#2673)
-- Docs: Fixed various typos in comments and documentations. (#5649, #5675, #5679) [@tocic, @lessigsx]
-- Demo: Improved "Constrained-resizing window" example, more clearly showcase aspect-ratio. (#5627)
-- Demo: Added more explicit "Center window" mode to "Overlay example". (#5618)
-- Demo: Fixed Log & Console from losing scrolling position with Auto-Scroll when child is clipped. (#5721)
-- Examples: Added all SDL examples to default VS solution.
-- Examples: Win32: Always use RegisterClassW() to ensure windows are Unicode. (#5725)
-- Examples: Android: Enable .ini file loading/saving into application internal data folder. (#5836) [@rewtio]
-- Backends: GLFW: Honor GLFW_CURSOR_DISABLED by not setting mouse position. (#5625) [@scorpion-26]
-- Backends: GLFW: Add glfwGetError() call on GLFW 3.3 to inhibit missing mouse cursor errors. (#5785) [@mitchellh]
-- Backends: SDL: Disable SDL 2.0.22 new "auto capture" which prevents drag and drop across windows
- (e.g. for multi-viewport support) and don't capture mouse when drag and dropping. (#5710)
-- Backends: Win32: Convert WM_CHAR values with MultiByteToWideChar() when window class was
- registered as MBCS (not Unicode). (#5725, #1807, #471, #2815, #1060) [@or75, @ocornut]
-- Backends: OSX: Fixed mouse inputs on flipped views. (#5756) [@Nemirtingas]

-- Backends: OSX: Fixes to support full app creation in C++. (#5403) [@stack]
-- Backends: OpenGL3: Reverted use of glBufferSubData(), too many corruptions issues were reported,
- and old leaks issues seemingly can't be reproed with Intel drivers nowadays (revert earlier changes).
- (#4468, #4504, #3381, #2981, #4825, #4832, #5127).
-- Backends: Metal: Use __bridge for ARC based systems. (#5403) [@stack]
-- Backends: Metal: Add dispatch synchronization. (#5447) [@luigifcruz]
-- Backends: Metal: Update deprecated property 'sampleCount'->'rasterSampleCount'. (#5603) [@dcvz]
-- Backends: Vulkan: Added experimental ImGui_ImplVulkan_RemoveTexture() for api symetry. (#914, #5738).
-- Backends: WebGPU: fixed rendering when a depth buffer is enabled. (#5869) [@brainlag]

------------------------------------------------------------------------
- VERSION 1.88 (Released 2022-06-21)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.88
-
-Breaking changes:
-
-- Renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS for correctness.
- Kept support for old define (will obsolete).
-- Renamed CaptureMouseFromApp() and CaptureKeyboardFromApp() to SetNextFrameWantCaptureMouse()
- and SetNextFrameWantCaptureKeyboard() to clarify purpose, old name was too misleading.
- Kept inline redirection functions (will obsolete).
-- Renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete).
- (This was never used in public API functions but technically present in imgui.h and ImGuiIO).
-- Backends: OSX: Removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend
- automatically handling event capture. Examples that are using the OSX backend have removed
- all the now-unnecessary calls to ImGui_ImplOSX_HandleEvent(), applications can do as well.
- [@stuartcarnie] (#4821)
-- Internals: calling ButtonBehavior() without calling ItemAdd() now requires a KeepAliveID()
- call. This is because the KeepAliveID() call was moved from GetID() to ItemAdd(). (#5181)
-
-Other Changes:
-
-- IO: Fixed backward-compatibility regression introduced in 1.87: (#4921, #4858)
- - Direct accesses to io.KeysDown[] with legacy indices didn't work (with new backends).
- - Direct accesses to io.KeysDown[GetKeyIndex(XXX)] would access invalid data (with old/new backends).
- - Calling IsKeyDown() didn't have those problems, and is recommended as io.KeysDown[] is obsolete.
-- IO: Fixed input queue trickling of interleaved keys/chars events (which are frequent especially
- when holding down a key as OS submits chars repeat events) delaying key presses and mouse movements.
- In particular, using the input system for fast game-like actions (e.g. WASD camera move) would
- typically have been impacted, as well as holding a key while dragging mouse. Constraints have
- been lifted and are now only happening when e.g. an InputText() widget is active. (#4921, #4858)
- Note that even thought you shouldn't need to disable io.ConfigInputTrickleEventQueue, you can
- technically dynamically change its setting based on the context (e.g. disable only when hovering
- or interacting with a game/3D view).
-- IO: Fixed input queue trickling of mouse wheel events: multiple wheel events are merged, while
- a mouse pos followed by a mouse wheel are now trickled. (#4921, #4821)
-- IO: Added io.SetAppAcceptingEvents() to set a master flag for accepting key/mouse/characters
- events (default to true). Useful if you have native dialog boxes that are interrupting your
- application loop/refresh, and you want to disable events being queued while your app is frozen.
-- Windows: Fixed first-time windows appearing in negative coordinates from being initialized
- with a wrong size. This would most often be noticeable in multi-viewport mode (docking branch)
- when spawning a window in a monitor with negative coordinates. (#5215, #3414) [@DimaKoltun]
-- Clipper: Fixed a regression in 1.86 when not calling clipper.End() and late destructing the
- clipper instance. High-level languages (Lua,Rust etc.) would typically be affected. (#4822)
-- Layout: Fixed mixing up SameLine() and SetCursorPos() together from creating situations where line
- height would be emitted from the wrong location (e.g. 'ItemA+SameLine()+SetCursorPos()+ItemB' would
- emit ItemA worth of height from the position of ItemB, which is not necessarily aligned with ItemA).
-- Sliders: An initial click within the knob/grab doesn't shift its position. (#1946, #5328)
-- Sliders, Drags: Fixed dragging when using hexadecimal display format string. (#5165, #3133)
-- Sliders, Drags: Fixed manual input when using hexadecimal display format string. (#5165, #3133)
-- InputScalar: Fixed manual input when using %03d style width in display format string. (#5165, #3133)
-- InputScalar: Automatically allow hexadecimal input when format is %X (without extra flag).
-- InputScalar: Automatically allow scientific input when format is float/double (without extra flag).
-- Nav: Fixed nav movement in a scope with only one disabled item from focusing the disabled item. (#5189)
-- Nav: Fixed issues with nav request being transferred to another window when calling SetKeyboardFocusHere()
- and simultaneous changing window focus. (#4449)
-- Nav: Changed SetKeyboardFocusHere() to not behave if a drag or window moving is in progress.
-- Nav: Fixed inability to cancel nav in modal popups. (#5400) [@rokups]
-- IsItemHovered(): added ImGuiHoveredFlags_NoNavOverride to disable the behavior where the
- return value is overridden by focus when gamepad/keyboard navigation is active.
-- InputText: Fixed pressing Tab emitting two tabs characters because of dual Keys/Chars events being
- trickled with the new input queue (happened on some backends only). (#2467, #1336)
-- InputText: Fixed a one-frame display glitch where pressing Escape to revert after a deletion
- would lead to small garbage being displayed for one frame. Curiously a rather old bug! (#3008)
-- InputText: Fixed an undo-state corruption issue when editing main buffer before reactivating item. (#4947)
-- InputText: Fixed an undo-state corruption issue when editing in-flight buffer in user callback.
- (#4947, #4949] [@JoshuaWebb]
-- Tables: Fixed incorrect border height used for logic when resizing one of several synchronized
- instance of a same table ID, when instances have a different height. (#3955).
-- Tables: Fixed incorrect auto-fit of parent windows when using non-resizable weighted columns. (#5276)
-- Tables: Fixed draw-call merging of last column. Depending on some unrelated settings (e.g. BorderH)
- merging draw-call of the last column didn't always work (regression since 1.87). (#4843, #4844) [@rokups]
-- Inputs: Fixed IsMouseClicked() repeat mode rate being half of keyboard repeat rate.
-- ColorEdit: Fixed text baseline alignment after a SameLine() after a ColorEdit() with visible label.
-- Tabs: BeginTabItem() now reacts to SetNextItemWidth(). (#5262)
-- Tabs: Tweak shrinking policy so that while resizing tabs that don't need shrinking keep their
- initial width more precisely (without the occasional +1 worth of width).
-- Menus: Adjusted BeginMenu() closing logic so hovering void or non-MenuItem() in parent window
- always lead to menu closure. Fixes using items that are not MenuItem() or BeginItem() at the root
- level of a popup with a child menu opened.
-- Menus: Menus emitted from the main/scrolling layer are not part of the same menu-set as menus emitted
- from the menu-bar, avoiding accidental hovering from one to the other. (#3496, #4797) [@rokups]
-- Style: Adjust default value of GrabMinSize from 10.0f to 12.0f.
-- Stack Tool: Added option to copy item path to clipboard. (#4631)
-- Settings: Fixed out-of-bounds read when .ini file on disk is empty. (#5351) [@quantum5]
-- Settings: Fixed some SetNextWindowPos/SetNextWindowSize API calls not marking settings as dirty.
-- DrawList: Fixed PathArcTo() emitting terminating vertices too close to arc vertices. (#4993) [@thedmd]
-- DrawList: Fixed texture-based anti-aliasing path with RGBA textures (#5132, #3245) [@cfillion]
-- DrawList: Fixed divide-by-zero or glitches with Radius/Rounding values close to zero. (#5249, #5293, #3491)
-- DrawList: Circle with a radius smaller than 0.5f won't appear, to be consistent with other primitives. [@thedmd]
-- Debug Tools: Debug Log: Added ShowDebugLogWindow() showing an opt-in synthetic log of principal events
- (focus, popup, active id changes) helping to diagnose issues.
-- Debug Tools: Added DebugTextEncoding() function to facilitate diagnosing issues when not sure about
- whether you have a UTF-8 text encoding issue or a font loading issue. [@LaMarche05, @ocornut]
-- Demo: Add better demo of how to use SetNextFrameWantCaptureMouse()/SetNextFrameWantCaptureKeyboard().
-- Metrics: Added a "UTF-8 Encoding Viewer" section using the aforementioned DebugTextEncoding() function.
-- Metrics: Added "InputText" section to visualize internal state (#4947, #4949).
-- Misc: Fixed calling GetID("label") _before_ a widget emitting this item inside a group (such as InputInt())
- from causing an assertion when closing the group. (#5181).
-- Misc: Fixed IsAnyItemHovered() returning false when using navigation.
-- Misc: Allow redefining IM_COL32_XXX layout macros to facilitate use on big-endian systems. (#5190, #767, #844)
-- Misc: Added IMGUI_STB_SPRINTF_FILENAME to support custom path to stb_sprintf. (#5068, #2954) [@jakubtomsu]
-- Misc: Added constexpr to ImVec2/ImVec4 inline constructors. (#4995) [@Myriachan]
-- Misc: Updated stb_truetype.h from 1.20 to 1.26 (many fixes). (#5075)
-- Misc: Updated stb_textedit.h from 1.13 to 1.14 (our changes so this effectively is a no-op). (#5075)
-- Misc: Updated stb_rect_pack.h from 1.00 to 1.01 (minor). (#5075)
-- Misc: binary_to_compressed_c tool: Added -nostatic option. (#5021) [@podsvirov]
-- ImVector: Fixed erase() with empty range. (#5009) [@thedmd]
-- Backends: Vulkan: Don't use VK_PRESENT_MODE_MAX_ENUM_KHR as specs state it isn't part of the API. (#5254)
-- Backends: GLFW: Fixed a regression in 1.87 which resulted in keyboard modifiers events being
- reported incorrectly on Linux/X11, due to a bug in GLFW. [@rokups]
-- Backends: GLFW: Fixed untranslated keys when pressing lower case letters on OSX (#5260, #5261) [@cpichard]
-- Backends: SDL: Fixed dragging out viewport broken on some SDL setups. (#5012) [@rokups]
-- Backends: SDL: Added support for extra mouse buttons (SDL_BUTTON_X1/SDL_BUTTON_X2). (#5125) [@sgiurgiu]
-- Backends: SDL, OpenGL3: Fixes to facilitate building on AmigaOS4. (#5190) [@afxgroup]
-- Backends: OSX: Monitor NSKeyUp events to catch missing keyUp for key when user press Cmd + key (#5128) [@thedmd]
-- Backends: OSX, Metal: Store backend data in a per-context struct, allowing to use these backends with
- multiple contexts. (#5203, #5221, #4141) [@noisewuwei]
-- Backends: Metal: Fixed null dereference on exit inside command buffer completion handler. (#5363, #5365) [@warrenm]
-- Backends: OpenGL3: Partially revert 1.86 change of using glBufferSubData(): now only done on Windows and
- Intel GPU, based on querying glGetString(GL_VENDOR). Essentially we got report of accumulating leaks on Intel
- with multi-viewports when using simple glBufferData() without orphaning, and report of corruptions on other
- GPUs with multi-viewports when using orphaning and glBufferSubData(), so currently switching technique based
- on GPU vendor, which unfortunately reinforce the cargo-cult nature of dealing with OpenGL drivers.
- Navigating the space of mysterious OpenGL drivers is particularly difficult as they are known to rely on
- application specific whitelisting. (#4468, #3381, #2981, #4825, #4832, #5127).
-- Backends: OpenGL3: Fix state corruption on OpenGL ES 2.0 due to not preserving GL_ELEMENT_ARRAY_BUFFER_BINDING
- and vertex attribute states. [@rokups]
-- Examples: Emscripten+WebGPU: Fix building for latest WebGPU specs. (#3632)
-- Examples: OSX+Metal, OSX+OpenGL: Removed now-unnecessary calls to ImGui_ImplOSX_HandleEvent(). (#4821)

------------------------------------------------------------------------
- VERSION 1.87 (Released 2022-02-07)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.87
-
-Breaking Changes:
-
-- Removed support for pre-C++11 compilers. We'll stop supporting VS2010. (#4537)
-- Reworked IO mouse input API: (#4921, #4858) [@thedmd, @ocornut]
- - Added io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() functions,
- obsoleting writing directly to io.MousePos, io.MouseDown[], io.MouseWheel, etc.
- - This enable input queue trickling to support low framerates. (#2787, #1992, #3383, #2525, #1320)
- - For all calls to IO new functions, the Dear ImGui context should be bound/current.
-- Reworked IO keyboard input API: (#4921, #2625, #3724) [@thedmd, @ocornut]
- - Added io.AddKeyEvent() function, obsoleting writing directly to io.KeyMap[], io.KeysDown[] arrays.
- - For keyboard modifiers, you can call io.AddKeyEvent() with ImGuiKey_ModXXX values,
- obsoleting writing directly to io.KeyCtrl, io.KeyShift etc.
- - Added io.SetKeyEventNativeData() function (optional) to pass native and old legacy indices.
- - Added full range of key enums in ImGuiKey (e.g. ImGuiKey_F1).
- - Added GetKeyName() helper function.
- - Obsoleted GetKeyIndex(): it is now unnecessary and will now return the same value.
- - All keyboard related functions taking 'int user_key_index' now take 'ImGuiKey key':
- - IsKeyDown(), IsKeyPressed(), IsKeyReleased(), GetKeyPressedAmount().
- - Added io.ConfigInputTrickleEventQueue (defaulting to true) to disable input queue trickling.
- - Backward compatibility:
- - All backends updated to use new functions.
- - Old backends populating those arrays should still work!
- - Calling e.g. IsKeyPressed(MY_NATIVE_KEY_XXX) will still work! (for a while)
- - Those legacy arrays will only be disabled if '#define IMGUI_DISABLE_OBSOLETE_KEYIO' is set in your imconfig.
- In a few versions, IMGUI_DISABLE_OBSOLETE_FUNCTIONS will automatically enable IMGUI_DISABLE_OBSOLETE_KEYIO,
- so this will be moved into the regular obsolescence path.
- - BREAKING: If your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A")
- this is a use case that will now assert and be breaking for your old backend.
- - Transition guide:
- - IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX)
- - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX)
- - Backend writing to io.KeyMap[],KeysDown[] -> backend should call io.AddKeyEvent(), if legacy indexing is desired, call io.SetKeyEventNativeData()
- - Basically the trick we took advantage of is that we previously only supported native keycode from 0 to 511,
- so ImGuiKey values can still express a legacy native keycode, and new named keys are all >= 512.
- - This will enable a few things in the future:
- - Access to portable keys allows for backend-agnostic keyboard input code. Until now it was difficult
- to share code using keyboard across project because of this gap. (#2625, #3724)
- - Access to full key ranges will allow us to develop a proper keyboard shortcut system. (#456)
- - io.SetKeyEventNativeData() include native keycode/scancode which may later be exposed. (#3141, #2959)
-- Reworked IO nav/gamepad input API and unifying inputs sources: (#4921, #4858, #787)
- - Added full range of ImGuiKey_GamepadXXXX enums (e.g. ImGuiKey_GamepadDpadUp, ImGuiKey_GamepadR2) to use with
- io.AddKeyEvent(), io.AddKeyAnalogEvent().
- - Added io.AddKeyAnalogEvent() function, obsoleting writing directly to io.NavInputs[] arrays.
-- Renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. (#2625)
-- Removed support for legacy arithmetic operators (+,+-,*,/) when inputing text into a slider/drag. (#4917, #3184)
- This doesn't break any api/code but a feature that was accessible by end-users (which seemingly no one used).
- (Instead you may implement custom expression evaluators to provide a better version of this).
-- Backends: GLFW: backend now uses glfwSetCursorPosCallback().
- - If calling ImGui_ImplGlfw_InitXXX with install_callbacks=true: nothing to do. is already done for you.
- - If calling ImGui_ImplGlfw_InitXXX with install_callbacks=false: you WILL NEED to register the GLFW callback
- using glfwSetCursorPosCallback() and forward it to the backend function ImGui_ImplGlfw_CursorPosCallback().
-- Backends: SDL: Added SDL_Renderer* parameter to ImGui_ImplSDL2_InitForSDLRenderer(), so backend can call
- SDL_GetRendererOutputSize() to obtain framebuffer size valid for hi-dpi. (#4927) [@Clownacy]
-- Commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019)
- - ImGui::SetNextTreeNodeOpen() -> use ImGui::SetNextItemOpen()
- - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x
- - ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing());
- - ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect
- - ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex
-- Removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn() for IME support.
- Because this field was mostly only ever used by Dear ImGui internally, not by backends nor the vast majority
- of user code, this should only affect a very small fraction for users who are already very IME-aware.
-- Obsoleted 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
- This removes an incompatibility between 'master' and 'multi-viewports' backends and toward enabling
- better support for IME. Updated backends accordingly. Because the old field is set by existing backends,
- we are keeping it (marked as obsolete).
-
-Other Changes:
-
-- IO: Added event based input queue API, which now trickles events to support low framerates. [@thedmd, @ocornut]
- Previously the most common issue case (button presses in low framerates) was handled by backend. This is now
- handled by core automatically for all kind of inputs. (#4858, #2787, #1992, #3383, #2525, #1320)
- - New IO functions for keyboard/gamepad: AddKeyEvent(), AddKeyAnalogEvent().
- - New IO functions for mouse: AddMousePosEvent(), AddMouseButtonEvent(), AddMouseWheelEvent().
-- IO: Unified key enums allow using key functions on key mods and gamepad values.
-- Fixed CTRL+Tab into an empty window causing artifacts on the highlight rectangle due to bad reordering on ImDrawCmd.
-- Fixed a situation where CTRL+Tab or Modal can occasionally lead to the creation of ImDrawCmd with zero triangles,
- which would makes the draw operation of some backends assert (e.g. Metal with debugging). (#4857)
-- Popups: Fixed a regression crash when a new window is created after a modal on the same frame. (#4920) [@rokups]
-- Popups: Fixed an issue when reopening a same popup multiple times would offset them by 1 pixel on the right. (#4936)

------------------------------------------------------------------------
- VERSION 1.86 (Released 2021-12-22)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.86
-
-Breaking Changes:
-
-- Removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges.
- Please open an issue if you think you really need this function. (#3841)
-- Backends: OSX: Added NSView* parameter to ImGui_ImplOSX_Init(). (#4759) [@stuartcarnie]
-- Backends: Marmalade: Removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example app. (#368, #375)
- Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings
-
-Other Changes:
-
-- Added an assertion for the common user mistake of using "" as an identifier at the root level of a window
- instead of using "##something". Empty identifiers are valid and useful in a very small amount of cases,
- but 99.9% of the time if you need an empty label you should use "##something". (#1414, #2562, #2807, #4008,
- #4158, #4375, #4548, #4657, #4796). READ THE FAQ ABOUT HOW THE ID STACK WORKS -> https://dearimgui.com/faq
-- Added GetMouseClickedCount() function, returning the number of successive clicks. (#3229) [@kudaba]
- (so IsMouseDoubleClicked(ImGuiMouseButton_Left) is same as GetMouseClickedCount(ImGuiMouseButton_Left) == 2,
- but it allows testing for triple clicks and more).
-- Modals: fixed issue hovering popups inside a child windows inside a modal. (#4676, #4527)
-- Modals, Popups, Windows: changes how appearing windows are interrupting popups and modals. (#4317) [@rokups]
- - appearing windows created from within the begin stack of a popup/modal will no longer close it.
- - appearing windows created not within the begin stack of a modal will no longer close the modal,
- and automatically appear behind it.
-- Fixed IsWindowFocused()/IsWindowHovered() issues with child windows inside popups. (#4676)
-- Nav: Ctrl+tabbing to cycle through windows is now enabled regardless of using the _NavEnableKeyboard
- configuration flag. This is part of an effort to generalize the use of keyboard inputs. (#4023, #787).
- Note that while this is active you can also moving windows (with arrow) and resize (shift+arrows).
-- Nav: tabbing now cycles through clipped items and scroll accordingly. (#4449)
-- Nav: pressing PageUp/PageDown/Home/End when in Menu layer automatically moves back to Main layer.
-- Nav: fixed resizing window from borders setting navigation to Menu layer.
-- Nav: prevent child from clipping items when using _NavFlattened and parent has a pending request.
-- Nav: pressing Esc to exit a child window reactivates the Nav highlight if it was disabled by mouse.
-- Nav: with ImGuiConfigFlags_NavEnableSetMousePos enabled: Fixed absolute mouse position when using
- Home/End leads to scrolling. Fixed not setting mouse position when a failed move request (e.g. when
- already at edge) reactivates the navigation highlight.
-- Menus: fixed closing a menu inside a popup/modal by clicking on the popup/modal. (#3496, #4797)
-- Menus: fixed closing a menu by clicking on its menu-bar item when inside a popup. (#3496, #4797) [@xndcn]
-- Menus: fixed menu inside a popup/modal not inhibiting hovering of items in the popup/modal. (#3496, #4797)
-- Menus: fixed sub-menu items inside a popups from closing the popup.
-- Menus: fixed top-level menu from not consistently using style.PopupRounding. (#4788)
-- InputText, Nav: fixed repeated calls to SetKeyboardFocusHere() preventing to use InputText(). (#4682)
-- Inputtext, Nav: fixed using SetKeyboardFocusHere() on InputTextMultiline(). (#4761)
-- InputText: made double-click select word, triple-line select line. Word delimitation logic differs
- slightly from the one used by CTRL+arrows. (#2244)
-- InputText: fixed ReadOnly flag preventing callbacks from receiving the text buffer. (#4762) [@actondev]
-- InputText: fixed Shift+Delete from not cutting into clipboard. (#4818, #1541) [@corporateshark]
-- InputTextMultiline: fixed incorrect padding when FrameBorder > 0. (#3781, #4794)
-- InputTextMultiline: fixed vertical tracking with large values of FramePadding.y. (#3781, #4794)
-- Separator: fixed cover all columns while called inside a table. (#4787)
-- Clipper: currently focused item is automatically included in clipper range.
- Fixes issue where e.g. drag and dropping an item and scrolling ensure the item source location is
- still submitted. (#3841, #1725) [@GamingMinds-DanielC, @ocornut]
-- Clipper: added ForceDisplayRangeByIndices() to force a given item (or several) to be stepped out
- during a clipping operation. (#3841) [@GamingMinds-DanielC]
-- Clipper: rework so gamepad/keyboard navigation doesn't create spikes in number of items requested
- by the clipper to display. (#3841)
-- Clipper: fixed content height declaration slightly mismatching the value of when not using a clipper.
- (an additional ItemSpacing.y was declared, affecting scrollbar range).
-- Clipper: various and incomplete changes to tame down scrolling and precision issues on very large ranges.
- Passing an explicit height to the clipper now allows larger ranges. (#3609, #3962).
-- Clipper: fixed invalid state when number of frozen table row is smaller than ItemCount.
-- Drag and Drop: BeginDragDropSource() with ImGuiDragDropFlags_SourceAllowNullID doesn't lose
- tooltip when scrolling. (#143)
-- Fonts: fixed infinite loop in ImFontGlyphRangesBuilder::AddRanges() when passing UINT16_MAX or UINT32_MAX
- without the IMGUI_USE_WCHAR32 compile-time option. (#4802) [@SlavicPotato]
-- Metrics: Added a node showing windows in submission order and showing the Begin() stack.
-- Misc: Added missing ImGuiMouseCursor_NotAllowed cursor for software rendering (when the
- io.MouseDrawCursor flag is enabled). (#4713) [@nobody-special666]
-- Misc: Fixed software mouse cursor being rendered multiple times if Render() is called more than once.
-- Misc: Fix MinGW DLL build issue (when IMGUI_API is defined). [@rokups]
-- CI: Add MinGW DLL build to test suite. [@rokups]
-- Backends: Vulkan: Call vkCmdSetScissor() at the end of render with a full-viewport to reduce
- likehood of issues with people using VK_DYNAMIC_STATE_SCISSOR in their app without calling
- vkCmdSetScissor() explicitly every frame. (#4644)
-- Backends: OpenGL3: Using buffer orphaning + glBufferSubData(), seems to fix leaks with multi-viewports
- with some Intel HD drivers, and perhaps improve performances. (#4468, #4504, #2981, #3381) [@parbo]
-- Backends: OpenGL2, Allegro5, Marmalade: Fixed mishandling of the ImDrawCmd::IdxOffset field.
- This is an old bug, but due to the way we created drawlists, it never had any visible side-effect before.
- The new code for handling Modal and CTRL+Tab dimming/whitening recently made the bug surface. (#4790)
-- Backends: Win32: Store left/right variants of Ctrl/Shift/Alt mods in KeysDown[] array. (#2625) [@thedmd]
-- Backends: DX12: Fixed DRAW_EMPTY_SCISSOR_RECTANGLE warnings. (#4775)
-- Backends: SDL_Renderer: Added support for large meshes (64k+ vertices) with 16-bit indices,
- enabling 'ImGuiBackendFlags_RendererHasVtxOffset' in the backend. (#3926) [@rokups]
-- Backends: SDL_Renderer: Fix for SDL 2.0.19+ RenderGeometryRaw() API signature change. (#4819) [@sridenour]
-- Backends: OSX: Generally fix keyboard support. Keyboard arrays indexed using kVK_* codes, e.g.
- ImGui::IsKeyPressed(kVK_Space). Don't set mouse cursor shape unconditionally. Handle two fingers scroll
- cancel event. (#4759, #4253, #1873) [@stuartcarnie]
-- Backends: OSX: Add Game Controller support (need linking GameController framework) (#4759) [@stuartcarnie]
-- Backends: WebGPU: Passing explicit buffer sizes to wgpuRenderPassEncoderSetVertexBuffer() and
- wgpuRenderPassEncoderSetIndexBuffer() functions as validation layers appears to not do what the
- in-flux specs says. (#4766) [@meshula]

------------------------------------------------------------------------
- VERSION 1.85 (Released 2021-10-12)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.85
-
-This is the last release officially supporting C++03 and Visual Studio 2008/2010. (#4537)
-We expect that the next release will require a subset of the C++11 language (VS 2012~, GCC 4.8.1, Clang 3.3).
-We may use some C++11 language features but we will not use any C++ library headers.
-If you are stuck on ancient compiler you may need to stay at this version onward.
-
-Breaking Changes:
-
-- Removed GetWindowContentRegionWidth() function. Kept inline redirection helper.
- Can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead but it's not
- very useful in practice, and the only use of it in the demo was illfit.
- Using 'GetContentRegionAvail().x' is generally a better choice.
-
-Other Changes:
-
-- Debug: Stack Tool: Added "Stack Tool" available in "Demo->Tools->Stack Tool", "Metrics->Tools",
- or by calling the ShowStackToolWindow() function. The tool run queries on hovered id to display
- details about individual components that were hashed to create an ID. It helps understanding
- the ID stack system and debugging potential ID collisions. (#4631) [@ocornut, @rokups]
-- Windows: Fixed background order of overlapping childs submitted sequentially. (#4493)
-- IsWindowFocused: Added ImGuiFocusedFlags_NoPopupHierarchy flag allowing to exclude child popups
- from the tested windows when combined with _ChildWindows.
-- IsWindowHovered: Added ImGuiHoveredFlags_NoPopupHierarchy flag allowing to exclude child popups
- from the tested windows when combined with _ChildWindows.
-- InputTextMultiline: Fixed label size not being included into window contents rect unless
- the whole widget is clipped.
-- InputText: Allow activating/cancelling/validating input with gamepad nav events. (#2321, #4552)
-- InputText: Fixed selection rectangle appearing one frame late when selecting all.
-- TextUnformatted: Accept null ranges including (NULL,NULL) without asserting, in order to conform
- to common idioms (e.g. passing .data(), .data() + .size() from a null string). (#3615)
-- Disabled: Added assert guard for mismatching BeginDisabled()/EndDisabled() blocks. (#211)
-- Nav: Fixed using SetKeyboardFocusHere() on non-visible/clipped items. It now works and will scroll
- toward the item. When called during a frame where the parent window is appearing, scrolling will
- aim to center the item in the window. When calling during a frame where the parent window is already
- visible, scrolling will aim to scroll as little as possible to make the item visible. We will later
- expose scroll functions and flags in public API to select those behaviors. (#343, #4079, #2352)
-- Nav: Fixed using SetKeyboardFocusHere() from activating a different item on the next frame if
- submitted items have changed during that frame. (#432)
-- Nav: Fixed toggling menu layer with Alt or exiting menu layer with Esc not moving mouse when
- the ImGuiConfigFlags_NavEnableSetMousePos config flag is set.
-- Nav: Fixed a few widgets from not setting reference keyboard/gamepad navigation ID when
- activated with mouse. More specifically: BeginTabItem(), the scrolling arrows of BeginTabBar(),
- the arrow section of TreeNode(), the +/- buttons of InputInt()/InputFloat(), Selectable() with
- ImGuiSelectableFlags_SelectOnRelease. More generally: any direct use of ButtonBehavior() with
- the PressedOnClick/PressedOnDoubleClick/PressedOnRelease button policy.
-- Nav: Fixed an issue with losing focus on docked windows when pressing Alt while keyboard navigation
- is disabled. (#4547, #4439) [@PathogenDavid]
-- Nav: Fixed vertical scoring offset when wrapping on Y in a decorated window.
-- Nav: Improve scrolling behavior when navigating to an item larger than view.
-- TreePush(): removed unnecessary/inconsistent legacy behavior where passing a NULL value to
- the TreePush(const char*) and TreePush(const void*) functions would use an hard-coded replacement.
- The only situation where that change would make a meaningful difference is TreePush((const char*)NULL)
- (_explicitly_ casting a null pointer to const char*), which is unlikely and will now crash.
- You may replace it with anything else.
-- ColorEdit4: Fixed not being able to change hue when saturation is 0. (#4014) [@rokups]
-- ColorEdit4: Fixed hue resetting to 0 when it is set to 255. [@rokups]
-- ColorEdit4: Fixed hue value jitter when source color is stored as RGB in 32-bit integer and perform
- RGB<>HSV round trips every frames. [@rokups]
-- ColorPicker4: Fixed picker being unable to select exact 1.0f color when dragging toward the edges
- of the SV square (previously picked 0.999989986f). (#3517) [@rokups]
-- Menus: Fixed vertical alignments of MenuItem() calls within a menu bar (broken in 1.84). (#4538)
-- Menus: Improve closing logic when moving diagonally in empty between between parent and child menus to
- accommodate for varying font size and dpi.
-- Menus: Fixed crash when navigating left inside a child window inside a sub-menu. (#4510).
-- Menus: Fixed an assertion happening in some situations when closing nested menus (broken in 1.83). (#4640)
-- Drag and Drop: Fixed using BeginDragDropSource() inside a BeginChild() that returned false. (#4515)
-- PlotHistogram: Fixed zero-line position when manually specifying min<0 and max>0. (#4349) [@filippocrocchini]
-- Misc: Added asserts for missing PopItemFlag() calls.
-- Misc: Fixed printf-style format checks on Clang+MinGW. (#4626, #4183, #3592) [@guusw]
-- IO: Added 'io.WantCaptureMouseUnlessPopupClose' alternative to `io.WantCaptureMouse'. (#4480)
- This allows apps to receive the click on void when that click is used to close popup (by default,
- clicking on a void when a popup is open will close the popup but not release io.WantCaptureMouse).
-- Fonts: imgui_freetype: Fixed crash when FT_Render_Glyph() fails to render a glyph and returns NULL
- (which apparently happens with Freetype 2.11). (#4394, #4145?).
-- Fonts: Fixed ImFontAtlas::ClearInputData() marking atlas as not built. (#4455, #3487)
-- Backends: Added more implicit asserts to detect invalid/redundant calls to Shutdown functions. (#4562)
-- Backends: OpenGL3: Fixed our custom GL loader conflicting with user using GL3W. (#4445) [@rokups]
-- Backends: WebGPU: Fixed for latest specs. (#4472, #4512) [@Kangz, @bfierz]
-- Backends: SDL_Renderer: Added SDL_Renderer backend compatible with upcoming SDL 2.0.18. (#3926) [@1bsyl]
-- Backends: Metal: Fixed a crash when clipping rect larger than framebuffer is submitted via
- a direct unclipped PushClipRect() call. (#4464)
-- Backends: OSX: Use mach_absolute_time as CFAbsoluteTimeGetCurrent can jump backwards. (#4557, #4563) [@lfnoise]
-- Backends: All renderers: Normalize clipping rect handling across backends. (#4464)
-- Examples: Added SDL + SDL_Renderer example in "examples/example_sdl_sdlrenderer/" folder. (#3926) [@1bsyl]

-
-- Disabled: Fixed nested BeginDisabled()/EndDisabled() calls. (#211, #4452, #4453, #4462) [@Legulysse]

------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.84
-
-Breaking Changes:
-
-- Commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019):
- - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList()
- - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder
-- Backends: OpenGL3: added a third source file "imgui_impl_opengl3_loader.h". (#4445) [@rokups]
-- Backends: GLFW: backend now uses glfwSetCursorEnterCallback(). (#3751, #4377, #2445)
-- Backends: GLFW: backend now uses glfwSetWindowFocusCallback(). (#4388) [@thedmd]
- - If calling ImGui_ImplGlfw_InitXXX with install_callbacks=true: this is already done for you.
- - If calling ImGui_ImplGlfw_InitXXX with install_callbacks=false: you WILL NEED to register the GLFW callbacks
- and forward them to the backend:
- - Register glfwSetCursorEnterCallback, forward events to ImGui_ImplGlfw_CursorEnterCallback().
- - Register glfwSetWindowFocusCallback, forward events to ImGui_ImplGlfw_WindowFocusCallback().
-- Backends: SDL2: removed unnecessary SDL_Window* parameter from ImGui_ImplSDL2_NewFrame(). (#3244) [@funchal]
- Kept inline redirection function (will obsolete).
-- Backends: SDL2: backend needs to set 'SDL_SetHint(SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH, "1")' in order to
- receive mouse clicks events on window focus, otherwise SDL doesn't emit the event. (#3751, #4377, #2445)
- This is unfortunately a global SDL setting, so enabling it _might_ have a side-effect on your application.
- It is unlikely to make a difference, but if your app absolutely needs to ignore the initial on-focus click:
- you can ignore SDL_MOUSEBUTTONDOWN events coming right after a SDL_WINDOWEVENT_FOCUS_GAINED event).
-- Internals: (for custom widgets): because disabled items now sets HoveredId, if you want custom widgets to
- not react as hovered when disabled, in the majority of use cases it is preferable to check the "hovered"
- return value of ButtonBehavior() rather than (HoveredId == id).
-
-Other Changes:
-
-- IO: Added io.AddFocusEvent() api for backend to tell when host window has gained/lost focus. (#4388) [@thedmd]
- If you use a custom backend, consider adding support for this!
-- Disabled: added BeginDisabled()/EndDisabled() api to create a scope where interactions are disabled. (#211)
- - Added style.DisabledAlpha (default to 0.60f) and ImGuiStyleVar_DisabledAlpha. (#211)
- - Unlike the internal-and-undocumented-but-somehow-known PushItemFlag(ImGuiItemFlags_Disabled), this also alters
- visuals. Currently this is done by lowering alpha of all widgets. Future styling system may do that differently.
- - Disabled items set HoveredId, allowing e.g. HoveredIdTimer to run. (#211, #3419) [@rokups]
- - Disabled items more consistently release ActiveId if the active item got disabled. (#211)
- - Nav: Fixed disabled items from being candidate for default focus. (#211, #787)
- - Fixed Selectable() selection not showing when disabled. (#211)
- - Fixed IsItemHovered() returning true on disabled item when navigated to. (#211)
- - Fixed IsItemHovered() when popping disabled state after item, or when using Selectable_Disabled. (#211)
-- Windows: ImGuiWindowFlags_UnsavedDocument/ImGuiTabItemFlags_UnsavedDocument displays a dot instead of a '*' so it
- is independent from font style. When in a tab, the dot is displayed at the same position as the close button.
- Added extra comments to clarify the purpose of this flag in the context of docked windows.
-- Tables: Added ImGuiTableColumnFlags_Disabled acting a master disable over (hidden from user/context menu). (#3935)
-- Tables: Clarified that TableSetColumnEnabled() requires the table to use the ImGuiTableFlags_Hideable flag,
- because it manipulates the user-accessible show/hide state. (#3935)
-- Tables: Added ImGuiTableColumnFlags_NoHeaderLabel to request TableHeadersRow() to not submit label for a column.
- Convenient for some small columns. Name will still appear in context menu. (#4206).
-- Tables: Fixed columns order on TableSetupScrollFreeze() if previous data got frozen columns out of their section.
-- Tables: Fixed invalid data in TableGetSortSpecs() when SpecsDirty flag is unset. (#4233)
-- Tabs: Fixed using more than 32 KB-worth of tab names. (#4176)
-- InputInt/InputFloat: When used with Steps values and _ReadOnly flag, the step button look disabled. (#211)
-- InputText: Fixed named filtering flags disabling newline or tabs in multiline inputs (#4409, #4410) [@kfsone]
-- Drag and Drop: drop target highlight doesn't try to bypass host clipping rectangle. (#4281, #3272)
-- Drag and Drop: Fixed using AcceptDragDropPayload() with ImGuiDragDropFlags_AcceptNoPreviewTooltip. [@JeffM2501]
-- Menus: MenuItem() and BeginMenu() are not affected/overlapping when style.SelectableTextAlign is altered.
-- Menus: Fixed hovering a disabled menu or menu item not closing other menus. (#211)
-- Popups: Fixed BeginPopup/OpenPopup sequence failing when there are no focused windows. (#4308) [@rokups]
-- Nav: Alt doesn't toggle menu layer if other modifiers are held. (#4439)
-- Fixed printf-style format checks on non-MinGW flavors. (#4183, #3592)
-- Fonts: Functions with a 'float size_pixels' parameter can accept zero if it is set in ImFontSize::SizePixels.
-- Fonts: Prefer using U+FFFD character for fallback instead of '?', if available. (#4269)
-- Fonts: Use U+FF0E dot character to construct an ellipsis if U+002E '.' is not available. (#4269)
-- Fonts: Added U+FFFD ("replacement character") to default asian glyphs ranges. (#4269)
-- Fonts: Fixed calling ClearTexData() (clearing CPU side font data) triggering an assert in NewFrame(). (#3487)
-- DrawList: Fixed AddCircle/AddCircleFilled() with auto-tesselation not using accelerated paths for small circles.
- Fixed AddCircle/AddCircleFilled() with 12 segments which had a broken edge. (#4419, #4421) [@thedmd]
-- Demo: Fixed requirement in 1.83 to link with imgui_demo.cpp if IMGUI_DISABLE_METRICS_WINDOW is not set. (#4171)
- Normally the right way to disable compiling the demo is to set IMGUI_DISABLE_DEMO_WINDOWS, but we want to avoid
- implying that the file is required.
-- Metrics: Fixed a crash when inspecting the individual draw command of a foreground drawlist. [@rokups]
-- Backends: Reorganized most backends (Win32, SDL, GLFW, OpenGL2/3, DX9/10/11/12, Vulkan, Allegro) to pull their
- data from a single structure stored inside the main Dear ImGui context. This facilitate/allow usage of standard
- backends with multiple-contexts BUT is only partially tested and not well supported. It is generally advised to
- instead use the multi-viewports feature of docking branch where a single Dear ImGui context can be used across
- multiple windows. (#586, #1851, #2004, #3012, #3934, #4141)
-- Backends: Win32: Rework to handle certain Windows 8.1/10 features without a manifest. (#4200, #4191)
- - ImGui_ImplWin32_GetDpiScaleForMonitor() will handle per-monitor DPI on Windows 10 without a manifest.
- - ImGui_ImplWin32_EnableDpiAwareness() will call SetProcessDpiAwareness() fallback on Windows 8.1 without a manifest.
-- Backends: Win32: IME functions are disabled by default for non-Visual Studio compilers (MinGW etc.). Enable with
- '#define IMGUI_ENABLE_WIN32_DEFAULT_IME_FUNCTIONS' for those compilers. Undo change from 1.82. (#2590, #738, #4185, #4301)
-- Backends: Win32: Mouse position is correctly reported when the host window is hovered but not focused. (#2445, #2696, #3751, #4377)
-- Backends: Win32, SDL2, GLFW, OSX, Allegro: now calling io.AddFocusEvent() on focus gain/loss. (#4388) [@thedmd]
- This allow us to ignore certain inputs on focus loss (previously relied on mouse loss but backends are now
- reporting mouse even when host window is unfocused, as per #2445, #2696, #3751, #4377)
-- Backends: Fixed keyboard modifiers being reported when host window doesn't have focus. (#2622)
-- Backends: GLFW: Mouse position is correctly reported when the host window is hovered but not focused. (#3751, #4377, #2445)
- (backend now uses glfwSetCursorEnterCallback(). If you called ImGui_ImplGlfw_InitXXX with install_callbacks=false, you will
- need to install this callback and forward the data to the backend via ImGui_ImplGlfw_CursorEnterCallback).
-- Backends: SDL2: Mouse position is correctly reported when the host window is hovered but not focused. (#3751, #4377, #2445)
- (enabled with SDL 2.0.5+ as SDL_GetMouseFocus() is only usable with SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH).
-- Backends: DX9: Explicitly disable texture state stages after >= 1. (#4268) [@NZJenkins]
-- Backends: DX12: Fix texture casting crash on 32-bit systems (introduced on 2021/05/19 and v1.83) + added comments
- about building on 32-bit systems. (#4225) [@kingofthebongo2008]
-- Backends: OpenGL3: Embed our own minimal GL headers/loader (imgui_impl_opengl3_loader.h) based on gl3w.
- Reduces the frequent issues and confusion coming from having to support multiple loaders and requiring users to use and
- initialize the same loader as the backend. (#4445) [@rokups]
- Removed support for gl3w, glew, glad, glad2, glbinding2, glbinding3 (all now unnecessary).
-- Backends: OpenGL3: Handle GL_CLIP_ORIGIN on <4.5 contexts if "GL_ARB_clip_control" extension is detected. (#4170, #3998)
-- Backends: OpenGL3: Destroy vertex/fragment shader objects right after they are linked into main shader. (#4244) [@Crowbarous]
-- Backends: OpenGL3: Use OES_vertex_array extension on Emscripten + backup/restore current state. (#4266, #4267) [@harry75369]
-- Backends: GLFW: Installing and exposed ImGui_ImplGlfw_MonitorCallback() for forward compatibility with docking branch.
-- Backends: OSX: Added a fix for shortcuts using CTRL key instead of CMD key. (#4253) [@rokups]
-- Examples: DX12: Fixed handling of Alt+Enter in example app (using swapchain's ResizeBuffers). (#4346) [@PathogenDavid]
-- Examples: DX12: Removed unnecessary recreation of backend-owned device objects when window is resized. (#4347) [@PathogenDavid]
-- Examples: OpenGL3+GLFW,SDL: Remove include cruft to support variety of GL loaders (no longer necessary). [@rokups]
-- Examples: OSX+OpenGL2: Fix event forwarding (fix key remaining stuck when using shortcuts with Cmd/Super key).
- Other OSX examples were not affected. (#4253, #1873) [@rokups]
-- Examples: Updated all .vcxproj to VS2015 (toolset v140) to facilitate usage with vcpkg.
-- Examples: SDL2: Accommodate for vcpkg install having headers in SDL2/SDL.h vs SDL.h.

-
-Breaking Changes:
-
-- Backends: Obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID(). (#3761) [@thedmd]
- - If you are using official backends from the source tree: you have nothing to do.
- - If you copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID().
- Why are we doing this?
- - This change will be required in the future when adding support for incremental texture atlas updates.
- - Please note this won't break soon, but we are making the change ahead of time.
-

- VERSION 1.82 (Released 2021-02-15)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.82
-
-Breaking Changes:
-
-- Removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018):
- - ImGui::SetScrollHere() --> use ImGui::SetScrollHereY()
-- ImDrawList: upgraded AddPolyline()/PathStroke()'s "bool closed" parameter to use "ImDrawFlags flags".
- - bool closed = false --> use ImDrawFlags_None, or 0
- - bool closed = true --> use ImDrawFlags_Closed
- The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
- Difference may not be noticeable for most but zealous type-checking tools may report a need to change.
-- ImDrawList: upgraded AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags.
- - ImDrawCornerFlags_TopLeft --> use ImDrawFlags_RoundCornersTopLeft
- - ImDrawCornerFlags_BotRight --> use ImDrawFlags_RoundCornersBottomRight
- - ImDrawCornerFlags_None --> use ImDrawFlags_RoundCornersNone etc.
- Flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API.
- IMPORTANT: The default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners":
- - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use)
- - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use)
- - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use)
- - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use)!
- - this ONLY matters for hardcoded use of 0 with rounding > 0.0f.
- - fix by using named ImDrawFlags_RoundCornersNone or rounding == 0.0f!
- - this is technically the only real breaking change which we can't solve automatically (it's also uncommon).
- The old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners"
- and we sometimes encouraged using them as shortcuts. As a result the legacy path still support use of hardcoded ~0
- or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise).
- Courtesy of legacy untangling commity: [@rokups, @ocornut, @thedmd]
-- ImDrawList: clarified that PathArcTo()/PathArcToFast() won't render with radius < 0.0f. Previously it sorts
- of accidentally worked but would lead to counter-clockwise paths which and have an effect on anti-aliasing.
-- InputText: renamed ImGuiInputTextFlags_AlwaysInsertMode to ImGuiInputTextFlags_AlwaysOverwrite, old name was an
- incorrect description of behavior. Was ostly used by memory editor. Kept inline redirection function. (#2863)
-- Moved 'misc/natvis/imgui.natvis' to 'misc/debuggers/imgui.natvis' as we will provide scripts for other debuggers.
-- Style: renamed rarely used style.CircleSegmentMaxError (old default = 1.60f)
- to style.CircleTessellationMaxError (new default = 0.30f) as its meaning changed. (#3808) [@thedmd]
-- Win32+MinGW: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly
- disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their
- imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'. (#2590, #738) [@actboy168]
- *EDIT* Undid in 1.84.
-- Backends: Win32: Pragma linking with dwmapi.lib (Vista-era, ~9 kb). MinGW users will need to link with -ldwmapi.
-
-Other Changes:
-
-- Window, Nav: Fixed crash when calling SetWindowFocus(NULL) at the time a new window appears. (#3865) [@nem0]
-- Window: Shrink close button hit-testing region when it covers an abnormally high portion of the window visible
- area (e.g. when window is collapsed + moved in a corner) to facilitate moving the window away. (#3825)
-- Nav: Various fixes for losing gamepad/keyboard navigation reference point when a window reappears or
- when it appears while gamepad/keyboard are not being used. (#787)
-- Drags: Fixed crash when using DragScalar() directly (not via common wrapper like DragFloat() etc.)
- with ImGuiSliderFlags_AlwaysClamp + only one of either p_min or p_max set. (#3824) [@harry75369]
-- Drags, Sliders: Fixed a bug where editing value would use wrong number if there were digits right after
- format specifier (e.g. using "%f123" as a format string). [@rokups]
-- Drags, Sliders: Fixed a bug where using custom formatting flags (',$,_) supported by stb_sprintf.h
- would cause incorrect value to be displayed. (#3604) [@rokups]
-- Drags, Sliders: Support ImGuiSliderFlags_Logarithmic flag with integers. Because why not? (#3786)
-- Tables: Fixed unaligned accesses when using TableSetBgColor(ImGuiTableBgTarget_CellBg). (#3872)
-- IsItemHovered(): fixed return value false positive when used after EndChild(), EndGroup() or widgets using
- either of them, when the hovered location is located within a child window, e.g. InputTextMultiline().
- This is intended to have no side effects, but brace yourself for the possible comeback.. (#3851, #1370)
-- Drag and Drop: can use BeginDragDropSource() for other than the left mouse button as long as the item
- has an ID (for ID-less items will add new functionalities later). (#1637, #3885)
-- ImFontAtlas: Added 'bool TexPixelsUseColors' output to help backend decide of underlying texture format. (#3369)
- This can currently only ever be set by the Freetype renderer.
-- imgui_freetype: Added ImGuiFreeTypeBuilderFlags_Bitmap flag to request Freetype loading bitmap data.
- This may have an effect on size and must be called with correct size values. (#3879) [@metarutaiga]
-- ImDrawList: PathArcTo() now supports "int num_segments = 0" (new default) and adaptively tessellate.
- The adaptive tessellation uses look up tables, tends to be faster than old PathArcTo() while maintaining
- quality for large arcs (tessellation quality derived from "style.CircleTessellationMaxError") (#3491) [@thedmd]
-- ImDrawList: PathArcToFast() also adaptively tessellate efficiently. This means that large rounded corners
- in e.g. hi-dpi settings will generally look better. (#3491) [@thedmd]
-- ImDrawList: AddCircle, AddCircleFilled(): Tweaked default segment count calculation to honor MaxError
- with more accuracy. Made default segment count always even for better looking result. (#3808) [@thedmd]
-- Misc: Added GetAllocatorFunctions() to facilitate sharing allocators across DLL boundaries. (#3836)
-- Misc: Added 'debuggers/imgui.gdb' and 'debuggers/imgui.natstepfilter' (along with existing 'imgui.natvis')
- scripts to configure popular debuggers into skipping trivial functions when using StepInto. [@rokups]
-- Backends: Android: Added native Android backend. (#3446) [@duddel]
-- Backends: Win32: Added ImGui_ImplWin32_EnableAlphaCompositing() to facilitate experimenting with
- alpha compositing and transparent windows. (#2766, #3447 etc.).
-- Backends: OpenGL, Vulkan, DX9, DX10, DX11, DX12, Metal, WebGPU, Allegro: Rework blending equation to
- preserve alpha in output buffer (using SrcBlendAlpha = ONE, DstBlendAlpha = ONE_MINUS_SRC_ALPHA consistently
- accross all backends), facilitating compositing of the output buffer with another buffer.
- (#2693, #2764, #2766, #2873, #3447, #3813, #3816) [@ocornut, @thedmd, @ShawnM427, @Ubpa, @aiekick]
-- Backends: DX9: Fix to support IMGUI_USE_BGRA_PACKED_COLOR. (#3844) [@Xiliusha]
-- Backends: DX9: Fix to support colored glyphs, using newly introduced 'TexPixelsUseColors' info. (#3844)
-- Examples: Android: Added Android + GL ES3 example. (#3446) [@duddel]
-- Examples: Reworked setup of clear color to be compatible with transparent values.
-- CI: Use a dedicated "scheduled" workflow to trigger scheduled builds. Forks may disable this workflow if
- scheduled builds builds are not required. [@rokups]
-- Log/Capture: Added LogTextV, a va_list variant of LogText. [@PathogenDavid]

------------------------------------------------------------------------
- VERSION 1.81 (Released 2021-02-10)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.81
-
-Breaking Changes:
-
-- ListBox helpers:
- - Renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox().
- - Renamed ListBoxFooter() to EndListBox().
- - Removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size.
- In the redirection function, made vertical padding consistent regardless of (items_count <= height_in_items) or not.
- - Kept inline redirection function for all threes (will obsolete).
-- imgui_freetype:
- - Removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function.
- Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too.
- - The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags.
- - Renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags.
- - Renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API.
-
-Other Changes:
-
-- Viewports Added ImGui::GetMainViewport() as a way to get the bounds and work area of the host display. (#3789, #1542)
- - In 'master' branch or without multi-viewports feature enabled:
- - GetMainViewport()->Pos is always == (0,0)
- - GetMainViewport()->Size is always == io.DisplaySize
- - In 'docking' branch and with the multi-viewports feature enabled:
- - GetMainViewport() will return information from your host Platform Window.
- - In the future, we will support a "no main viewport" mode and this may return bounds of your main monitor.
- - For forward compatibility with multi-viewports/multi-monitors:
- - Code using (0,0) as a way to signify "upper-left of the host window" should use GetMainViewport()->Pos.
- - Code using io.DisplaySize as a way to signify "size of the host window" should use GetMainViewport()->Size.
- - We are also exposing a work area in ImGuiViewport ('WorkPos', 'WorkSize' vs 'Pos', 'Size' for full area):
- - For a Platform Window, the work area is generally the full area minus space used by menu-bars.
- - For a Platform Monitor, the work area is generally the full area minus space used by task-bars.
- - All of this has been the case in 'docking' branch for a long time. What we've done is merely merging
- a small chunk of the multi-viewport logic into 'master' to standardize some concepts ahead of time.
-- Tables: Fixed PopItemWidth() or multi-components items not restoring per-colum ItemWidth correctly. (#3760)
-- Window: Fixed minor title bar text clipping issue when FramePadding is small/zero and there are no
- close button in the window. (#3731)
-- SliderInt: Fixed click/drag when v_min==v_max from setting the value to zero. (#3774) [@erwincoumans]
- Would also repro with DragFloat() when using ImGuiSliderFlags_Logarithmic with v_min==v_max.
-- Menus: Fixed an issue with child-menu auto sizing (issue introduced in 1.80 on 2021/01/25) (#3779)
-- InputText: Fixed slightly off ScrollX tracking, noticeable with large values of FramePadding.x. (#3781)
-- InputText: Multiline: Fixed padding/cliprect not precisely matching single-line version. (#3781)
-- InputText: Multiline: Fixed FramePadding.y worth of vertical offset when aiming with mouse.
-- ListBox: Tweaked default height calculation.
-- Fonts: imgui_freetype: Facilitated using FreeType integration: [@Xipiryon, @ocornut]
- - Use '#define IMGUI_ENABLE_FREETYPE' in imconfig.h should make it work with no other modifications
- other than compiling misc/freetype/imgui_freetype.cpp and linking with FreeType.
- - Use '#define IMGUI_ENABLE_STB_TRUETYPE' if you somehow need the stb_truetype rasterizer to be
- compiled in along with the FreeType one, otherwise it is enabled by default.
-- Fonts: imgui_freetype: Added support for colored glyphs as supported by Freetype 2.10+ (for .ttf using CPAL/COLR
- tables only). Enable the ImGuiFreeTypeBuilderFlags_LoadColor on a given font. Atlas always output directly
- as RGBA8 in this situation. Likely to make sense with IMGUI_USE_WCHAR32. (#3369) [@pshurgal]
-- Fonts: Fixed CalcTextSize() width rounding so it behaves more like a ceil. This is in order for text wrapping
- to have enough space when provided width precisely calculated with CalcTextSize().x. (#3776)
- Note that the rounding of either positions and widths are technically undesirable (e.g. #3437, #791) but
- variety of code is currently on it so we are first fixing current behavior before we'll eventually change it.
-- Log/Capture: Fix various new line/spacing issue when logging widgets. [@Xipiryon, @ocornut]
-- Log/Capture: Improved the ASCII look of various widgets, making large dumps more easily human readable.
-- ImDrawList: Fixed AddCircle()/AddCircleFilled() with (rad > 0.0f && rad < 1.0f && num_segments == 0). (#3738)
- Would lead to a buffer read overflow.
-- ImDrawList: Clarified PathArcTo() need for a_min <= a_max with an assert.
-- ImDrawList: Fixed PathArcToFast() handling of a_min > a_max.
-- Metrics: Back-ported "Viewports" debug visualizer from 'docking' branch.
-- Demo: Added 'Examples->Fullscreen Window' demo using GetMainViewport() values. (#3789)
-- Demo: 'Simple Overlay' demo now moves under main menu-bar (if any) using GetMainViewport()'s work area.
-- Backends: Win32: Dynamically loading XInput DLL instead of linking with it, facilitate compiling with
- old WindowSDK versions or running on Windows 7. (#3646, #3645, #3248, #2716) [@Demonese]
-- Backends: Vulkan: Add support for custom Vulkan function loader and VK_NO_PROTOTYPES. (#3759, #3227) [@Hossein-Noroozpour]
- User needs to call ImGui_ImplVulkan_LoadFunctions() with their custom loader prior to other functions.
-- Backends: Metal: Fixed texture storage mode when building on Mac Catalyst. (#3748) [@Belinsky-L-V]
-- Backends: OSX: Fixed mouse position not being reported when mouse buttons other than left one are down. (#3762) [@rokups]
-- Backends: WebGPU: Added enderer backend for WebGPU support (imgui_impl_wgpu.cpp) (#3632) [@bfierz]
- Please note that WebGPU is currently experimental, will not run on non-beta browsers, and may break.
-- Examples: WebGPU: Added Emscripten+WebGPU example. (#3632) [@bfierz]
-- Backends: GLFW: Added ImGui_ImplGlfw_InitForOther() initialization call to use with non OpenGL API. (#3632)

- - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X was value for decimal_precision.
- - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter.
-- Removed redirecting functions/enums names that were marked obsolete in 1.63 (August 2018):
- - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit().
- - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg
- - ImGuiInputTextCallback -> use ImGuiTextEditCallback
- - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData
-- If you were still using the old names, while you are cleaning up, considering enabling
- IMGUI_DISABLE_OBSOLETE_FUNCTIONS in imconfig.h even temporarily to have a pass at finding
- and removing up old API calls, if any remaining.
-- Internals: Columns: renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* to reduce
- confusion with Tables API. Keep redirection enums (will obsolete). (#125, #513, #913, #1204, #1444, #2142, #2707)
-- Renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature now applies
- to other data structures. (#2636)
-
-Other Changes:
-
-- Tables: added new Tables Beta API as a replacement for old Columns. (#3740, #2957, #125)
- Check out 'Demo->Tables' for many demos.
- Read API comments in imgui.h for details. Read extra commentary in imgui_tables.cpp.
- - Added 16 functions:
- - BeginTable(), EndTable()
- - TableNextRow(), TableNextColumn(), TableSetColumnIndex()
- - TableSetupColumn(), TableSetupScrollFreeze()
- - TableHeadersRow(), TableHeader()
- - TableGetRowIndex(), TableGetColumnCount(), TableGetColumnIndex(), TableGetColumnName(), TableGetColumnFlags()
- - TableGetSortSpecs(), TableSetBgColor()
- - Added 3 flags sets:
- - ImGuiTableFlags (29 flags for: features, decorations, sizing policies, padding, clipping, scrolling, sorting etc.)
- - ImGuiTableColumnFlags (24 flags for: width policies, default settings, sorting options, indentation options etc.)
- - ImGuiTableRowFlags (1 flag for: header row)
- - Added 2 structures: ImGuiTableSortSpecs, ImGuiTableColumnSortSpecs
- - Added 2 enums: ImGuiSortDirection, ImGuiTableBgTarget
- - Added 1 style variable: ImGuiStyleVar_CellPadding
- - Added 5 style colors: ImGuiCol_TableHeaderBg, ImGuiCol_TableBorderStrong, ImGuiCol_TableBorderLight, ImGuiCol_TableRowBg, ImGuiCol_TableRowBgAlt.
-- Tabs: Made it possible to append to an existing tab bar by calling BeginTabBar()/EndTabBar() again.
-- Tabs: Fixed using more than 128 tabs in a tab bar (scrolling policy recommended).
-- Tabs: Do not display a tooltip if the name already fits over a given tab. (#3521)
-- Tabs: Fixed minor/unlikely bug skipping over a button when scrolling left with arrows.
-- Tabs: Requested ideal content size (for auto-fit) doesn't affect horizontal scrolling. (#3414)
-- Drag and Drop: Fix losing drop source ActiveID (and often source tooltip) when opening a TreeNode()
- or CollapsingHeader() while dragging. (#1738)
-- Drag and Drop: Fix drag and drop to tie same-size drop targets by chosen the later one. Fixes dragging
- into a full-window-sized dockspace inside a zero-padded window. (#3519, #2717) [@Black-Cat]
-- Checkbox: Added CheckboxFlags() helper with int* type (internals have a template version, not exposed).
-- Clipper: Fixed incorrect end-list positioning when using ImGuiListClipper with 1 item (bug in 1.79). (#3663) [@nyorain]
-- InputText: Fixed updating cursor/selection position when a callback altered the buffer in a way
- where the byte count is unchanged but the decoded character count changes. (#3587) [@gqw]
-- InputText: Fixed switching from single to multi-line while preserving same ID.
-- Combo: Fixed using IsItemEdited() after Combo() not matching the return value from Combo(). (#2034)
-- DragFloat, DragInt: very slightly increased mouse drag threshold + expressing it as a factor of default value.
-- DragFloat, DragInt: added experimental io.ConfigDragClickToInputText feature to enable turning DragXXX widgets
- into text input with a simple mouse click-release (without moving). (#3737)
-- Nav: Fixed IsItemFocused() from returning false when Nav highlight is hidden because mouse has moved.
- It's essentially been always the case but it doesn't make much sense. Instead we will aim at exposing
- feedback and control of keyboard/gamepad navigation highlight and mouse hover disable flag. (#787, #2048)
-- Metrics: Fixed mishandling of ImDrawCmd::VtxOffset in wireframe mesh renderer.
-- Metrics: Rebranded as "Dear ImGui Metrics/Debugger" to clarify its purpose.
-- ImDrawList: Added ImDrawList::AddQuadBezierCurve(), ImDrawList::PathQuadBezierCurveTo() quadratic bezier
- helpers. (#3127, #3664, #3665) [@aiekick]
-- Fonts: Updated GetGlyphRangesJapanese() to include a larger 2999 ideograms selection of Joyo/Jinmeiyo
- kanjis, from the previous 1946 ideograms selection. This will consume a some more memory but be generally
- much more fitting for Japanese display, until we switch to a more dynamic atlas. (#3627) [@vaiorabbit]
-- Log/Capture: fix capture to work on clipped child windows.
-- Misc: Made the ItemFlags stack shared, so effectively the ButtonRepeat/AllowKeyboardFocus states
- (and others exposed in internals such as PushItemFlag) are inherited by stacked Begin/End pairs,
- vs previously a non-child stacked Begin() would reset those flags back to zero for the stacked window.
-- Misc: Replaced UTF-8 decoder with one based on branchless one by Christopher Wellons. [@rokups]
- Super minor fix handling incomplete UTF-8 contents: if input does not contain enough bytes, decoder
- returns IM_UNICODE_CODEPOINT_INVALID and consume remaining bytes (vs old decoded consumed only 1 byte).
-- Misc: Fix format warnings when using gnu printf extensions in a setup that supports them (gcc/mingw). (#3592)
-- Misc: Made EndFrame() assertion for key modifiers being unchanged during the frame (added in 1.76) more
- lenient, allowing full mid-frame releases. This is to accommodate the use of mid-frame modal native
- windows calls, which leads backends such as GLFW to send key clearing events on focus loss. (#3575)
-- Style: Changed default style.WindowRounding value to 0.0f (matches default for multi-viewports).
-- Style: Reduced the size of the resizing grip, made alpha less prominent.
-- Style: Classic: Increase the default alpha value of WindowBg to be closer to other styles.
-- Demo: Clarify usage of right-aligned items in Demo>Layout>Widgets Width.
-- Backends: OpenGL3: Use glGetString(GL_VERSION) query instead of glGetIntegerv(GL_MAJOR_VERSION, ...)
- when the later returns zero (e.g. Desktop GL 2.x). (#3530) [@xndcn]
-- Backends: OpenGL2: Backup and restore GL_SHADE_MODEL and disable GL_NORMAL_ARRAY state to increase
- compatibility with legacy code. (#3671)
-- Backends: OpenGL3: Backup and restore GL_PRIMITIVE_RESTART state. (#3544) [@Xipiryon]
-- Backends: OpenGL2, OpenGL3: Backup and restore GL_STENCIL_TEST enable state. (#3668)
-- Backends: Vulkan: Added support for specifying which sub-pass to reference during VkPipeline creation. (@3579) [@bdero]
-- Backends: DX12: Improve Windows 7 compatibility (for D3D12On7) by loading d3d12.dll dynamically. (#3696) [@Mattiwatti]
-- Backends: Win32: Fix setting of io.DisplaySize to invalid/uninitialized data after hwnd has been closed.
-- Backends: OSX: Fix keypad-enter key not working on MacOS. (#3554) [@rokups, @lfnoise]
-- Examples: Apple+Metal: Consolidated/simplified to get closer to other examples. (#3543) [@warrenm]
-- Examples: Apple+Metal: Forward events down so OS key combination like Cmd+Q can work. (#3554) [@rokups]
-- Examples: Emscripten: Renamed example_emscripten/ to example_emscripten_opengl3/. (#3632)
-- Examples: Emscripten: Added 'make serve' helper to spawn a web-server on localhost. (#3705) [@Horki]
-- Examples: DirectX12: Move ImGui::Render() call above the first barrier to clarify its lack of effect on the graphics pipe.
-- CI: Fix testing for Windows DLL builds. (#3603, #3601) [@iboB]
-- Docs: Improved the wiki and added a https://github.com/ocornut/imgui/wiki/Useful-Widgets page. [@Xipiryon]
- [2021/05/20: moved to https://github.com/ocornut/imgui/wiki/Useful-Extensions]
-- Docs: Split examples/README.txt into docs/BACKENDS.md and docs/EXAMPLES.md, and improved them.
-- Docs: Consistently renamed all occurrences of "binding" and "back-end" to "backend" in comments and docs.

------------------------------------------------------------------------
- VERSION 1.79 (Released 2020-10-08)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.79
-
-Breaking Changes:
-
-- Fonts: Removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied
- after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font.
- It was also getting in the way of better font scaling, so let's get rid of it now!
- If you used DisplayOffset it was probably in association to rasterizing a font at a specific size,
- in which case the corresponding offset may be reported into GlyphOffset. (#1619)
- If you scaled this value after calling AddFontDefault(), this is now done automatically.
-- ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using
- the ImGuiListClipper::Begin() function, with misleading edge cases. Always use ImGuiListClipper::Begin()!
- Kept inline redirection function (will obsolete).
- (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed).
-- Style: Renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton.
-- Renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete).
-- Renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), REVERTED CHANGE FROM 1.77.
- For variety of reason this is more self-explanatory and less error-prone. Kept inline redirection function.
-- Removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it
- is inconsistent with other popups API and makes others misleading. It's also and unnecessary: you can
- use IsWindowAppearing() after BeginPopup() for a similar result.
-
-Other Changes:
-
-- Window: Fixed using non-zero pivot in SetNextWindowPos() when the window is collapsed. (#3433)
-- Nav: Fixed navigation resuming on first visible item when using gamepad. [@rokups]
-- Nav: Fixed using Alt to toggle the Menu layer when inside a Modal window. (#787)
-- Scrolling: Fixed SetScrollHere(0) functions edge snapping when called during a frame where
- ContentSize is changing (issue introduced in 1.78). (#3452).
-- InputText: Added support for Page Up/Down in InputTextMultiline(). (#3430) [@Xipiryon]
-- InputText: Added selection helpers in ImGuiInputTextCallbackData().
-- InputText: Added ImGuiInputTextFlags_CallbackEdit to modify internally owned buffer after an edit.
- (note that InputText() already returns true on edit, the callback is useful mainly to manipulate the
- underlying buffer while focus is active).
-- InputText: Fixed using ImGuiInputTextFlags_Password with InputTextMultiline(). (#3427, #3428)
- It is a rather unusual or useless combination of features but no reason it shouldn't work!
-- InputText: Fixed minor scrolling glitch when erasing trailing lines in InputTextMultiline().
-- InputText: Fixed cursor being partially covered after using Ctrl+End key.
-- InputText: Fixed callback's helper DeleteChars() function when cursor is inside the deleted block. (#3454)
-- InputText: Made pressing Down arrow on the last line when it doesn't have a carriage return not move to
- the end of the line (so it is consistent with Up arrow, and behave same as Notepad and Visual Studio.
- Note that some other text editors instead would move the cursor to the end of the line). [@Xipiryon]
-- DragFloat, DragScalar: Fixed ImGuiSliderFlags_ClampOnInput not being honored in the special case
- where v_min == v_max. (#3361)
-- SliderInt, SliderScalar: Fixed reaching of maximum value with inverted integer min/max ranges, both
- with signed and unsigned types. Added reverse Sliders to Demo. (#3432, #3449) [@rokups]
-- Text: Bypass unnecessary formatting when using the TextColored()/TextWrapped()/TextDisabled() helpers
- with a "%s" format string. (#3466)
-- CheckboxFlags: Display mixed-value/tristate marker when passed flags that have multiple bits set and
- stored value matches neither zero neither the full set.
-- BeginMenuBar: Fixed minor bug where CursorPosMax gets pushed to CursorPos prior to calling BeginMenuBar(),
- so e.g. calling the function at the end of a window would often add +ItemSpacing.y to scrolling range.
-- TreeNode, CollapsingHeader: Made clicking on arrow toggle toggle the open state on the Mouse Down event
- rather than the Mouse Down+Up sequence, even if the _OpenOnArrow flag isn't set. This is standard behavior
- and amends the change done in 1.76 which only affected cases were _OpenOnArrow flag was set.
- (This is also necessary to support full multi/range-select/drag and drop operations.)
-- Tabs: Added TabItemButton() to submit tab that behave like a button. (#3291) [@Xipiryon]
-- Tabs: Added ImGuiTabItemFlags_Leading and ImGuiTabItemFlags_Trailing flags to position tabs or button
- at either end of the tab bar. Those tabs won't be part of the scrolling region, and when reordering cannot
- be moving outside of their section. Most often used with TabItemButton(). (#3291) [@Xipiryon]
-- Tabs: Added ImGuiTabItemFlags_NoReorder flag to disable reordering a given tab.
-- Tabs: Keep tab item close button visible while dragging a tab (independent of hovering state).
-- Tabs: Fixed a small bug where closing a tab that is not selected would leave a tab hole for a frame.
-- Tabs: Fixed a small bug where scrolling buttons (with ImGuiTabBarFlags_FittingPolicyScroll) would
- generate an unnecessary extra draw call.
-- Tabs: Fixed a small bug where toggling a tab bar from Reorderable to not Reorderable would leave
- tabs reordered in the tab list popup. [@Xipiryon]
-- Columns: Fix inverted ClipRect being passed to renderer when using certain primitives inside of
- a fully clipped column. (#3475) [@szreder]
-- Popups, Tooltips: Fix edge cases issues with positioning popups and tooltips when they are larger than
- viewport on either or both axises. [@Rokups]
-- Fonts: AddFontDefault() adjust its vertical offset based on floor(size/13) instead of always +1.
- Was previously done by altering DisplayOffset.y but wouldn't work for DPI scaled font.
-- Metrics: Various tweaks, listing windows front-to-back, greying inactive items when possible.
-- Demo: Add simple InputText() callbacks demo (aside from the more elaborate ones in 'Examples->Console').
-- Backends: OpenGL3: Fix to avoid compiling/calling glBindSampler() on ES or pre 3.3 contexts which have
- the defines set by a loader. (#3467, #1985) [@jjwebb]
-- Backends: Vulkan: Some internal refactor aimed at allowing multi-viewport feature to create their
- own render pass. (#3455, #3459) [@FunMiles]
-- Backends: DX12: Clarified that imgui_impl_dx12 can be compiled on 32-bit systems by redefining
- the ImTextureID to be 64-bit (e.g. '#define ImTextureID ImU64' in imconfig.h). (#301)
-- Backends: DX12: Fix debug layer warning when scissor rect is zero-sized. (#3472, #3462) [@StoneWolf]
-- Examples: Vulkan: Reworked buffer resize handling, fix for Linux/X11. (#3390, #2626) [@RoryO]
-- Examples: Vulkan: Switch validation layer to use "VK_LAYER_KHRONOS_validation" instead of
- "VK_LAYER_LUNARG_standard_validation" which is deprecated (#3459) [@FunMiles]
-- Examples: DX12: Enable breaking on any warning/error when debug interface is enabled.
-- Examples: DX12: Added '#define ImTextureID ImU64' in project and build files to also allow building
- on 32-bit systems. Added project to default Visual Studio solution file. (#301)

------------------------------------------------------------------------
- VERSION 1.78 (Released 2020-08-18)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.78
-
-Breaking Changes:
-
-- Obsoleted use of the trailing 'float power=1.0f' parameter for those functions: [@Shironekoben, @ocornut]
- - DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN()
- - SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN()
- - VSliderFloat(), VSliderScalar()
- Replaced the final 'float power=1.0f' argument with ImGuiSliderFlags defaulting to 0 (as with all our flags).
- Worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected.
- In short, when calling those functions:
- - If you omitted the 'power' parameter (likely!), you are not affected.
- - If you set the 'power' parameter to 1.0f (same as previous default value):
- - Your compiler may warn on float>int conversion.
- - Everything else will work (but will assert if IMGUI_DISABLE_OBSOLETE_FUNCTIONS is defined).
- - You can replace the 1.0f value with 0 to fix the warning, and be technically correct.
- - If you set the 'power' parameter to >1.0f (to enable non-linear editing):
- - Your compiler may warn on float>int conversion.
- - Code will assert at runtime for IM_ASSERT(power == 1.0f) with the following assert description:
- "Call Drag function with ImGuiSliderFlags_Logarithmic instead of using the old 'float power' function!".
- - In case asserts are disabled, the code will not crash and enable the _Logarithmic flag.
- - You can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert
- and get a _similar_ effect as previous uses of power >1.0f.
- See https://github.com/ocornut/imgui/issues/3361 for all details.
- For shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.
- Kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar().
- For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used.
-- DragInt, DragFloat, DragScalar: Obsoleted use of v_min > v_max to lock edits (introduced in 1.73, this was not
- demoed nor documented much, will be replaced a more generic ReadOnly feature).
-
-Other Changes:
-
-- Nav: Fixed clicking on void (behind any windows) from not clearing the focused window.
- This would be problematic e.g. in situation where the application relies on io.WantCaptureKeyboard
- flag being cleared accordingly. (bug introduced in 1.77 WIP on 2020/06/16) (#3344, #2880)
-- Window: Fixed clicking over an item which hovering has been disabled (e.g inhibited by a popup)
- from marking the window as moved.
-- Drag, Slider: Added ImGuiSliderFlags parameters.
- - For float functions they replace the old trailing 'float power=1.0' parameter.
- (See #3361 and the "Breaking Changes" block above for all details).
- - Added ImGuiSliderFlags_Logarithmic flag to enable logarithmic editing
- (generally more precision around zero), as a replacement to the old 'float power' parameter
- which was obsoleted. (#1823, #1316, #642) [@Shironekoben, @AndrewBelt]
- - Added ImGuiSliderFlags_ClampOnInput flag to force clamping value when using
- CTRL+Click to type in a value manually. (#1829, #3209, #946, #413).
- [note: RENAMED to ImGuiSliderFlags_AlwaysClamp in 1.79].
- - Added ImGuiSliderFlags_NoRoundToFormat flag to disable rounding underlying
- value to match precision of the display format string. (#642)
- - Added ImGuiSliderFlags_NoInput flag to disable turning widget into a text input
- with CTRL+Click or Nav Enter.
-- Nav, Slider: Fix using keyboard/gamepad controls with certain logarithmic sliders where
- pushing a direction near zero values would be cancelled out. [@Shironekoben]
-- DragFloatRange2, DragIntRange2: Fixed an issue allowing to drag out of bounds when both
- min and max value are on the same value. (#1441)
-- InputText, ImDrawList: Fixed assert triggering when drawing single line of text with more
- than ~16 KB characters. (Note that current code is going to show corrupted display if after
- clipping, more than 16 KB characters are visible in the same low-level ImDrawList::RenderText()
- call. ImGui-level functions such as TextUnformatted() are not affected. This is quite rare
- but it will be addressed later). (#3349)
-- Selectable: Fixed highlight/hit extent when used with horizontal scrolling (in or outside columns).
- Also fixed related text clipping when used in a column after the first one. (#3187, #3386)
-- Scrolling: Avoid SetScroll, SetScrollFromPos functions from snapping on the edge of scroll
- limits when close-enough by (WindowPadding - ItemPadding), which was a tweak with too many
- side-effects. The behavior is still present in SetScrollHere functions as they are more explicitly
- aiming at making widgets visible. May later be moved to a flag.
-- Tabs: Allow calling SetTabItemClosed() after a tab has been submitted (will process next frame).
-- InvisibleButton: Made public a small selection of ImGuiButtonFlags (previously in imgui_internal.h)
- and allowed to pass them to InvisibleButton(): ImGuiButtonFlags_MouseButtonLeft/Right/Middle.
- This is a small but rather important change because lots of multi-button behaviors could previously
- only be achieved using lower-level/internal API. Now also available via high-level InvisibleButton()
- with is a de-facto versatile building block to creating custom widgets with the public API.
-- Fonts: Fixed ImFontConfig::GlyphExtraSpacing and ImFontConfig::PixelSnapH settings being pulled
- from the merged/target font settings when merging fonts, instead of being pulled from the source
- font settings.
-- ImDrawList: Thick anti-aliased strokes (> 1.0f) with integer thickness now use a texture-based
- path, reducing the amount of vertices/indices and CPU/GPU usage. (#3245) [@Shironekoben]
- - This change will facilitate the wider use of thick borders in future style changes.
- - Requires an extra bit of texture space (~64x64 by default), relies on GPU bilinear filtering.
- - Set `io.AntiAliasedLinesUseTex = false` to disable rendering using this method.
- - Clear `ImFontAtlasFlags_NoBakedLines` in ImFontAtlas::Flags to disable baking data in texture.
-- ImDrawList: changed AddCircle(), AddCircleFilled() default num_segments from 12 to 0, effectively
- enabling auto-tessellation by default. Tweak tessellation in Style Editor->Rendering section, or
- by modifying the 'style.CircleSegmentMaxError' value. [@ShironekoBen]
-- ImDrawList: Fixed minor bug introduced in 1.75 where AddCircle() with 12 segments would generate
- an extra vertex. (This bug was mistakenly marked as fixed in earlier 1.77 release). [@ShironekoBen]
-- Demo: Improved "Custom Rendering"->"Canvas" demo with a grid, scrolling and context menu.
- Also showcase using InvisibleButton() with multiple mouse buttons flags.
-- Demo: Improved "Layout & Scrolling" -> "Clipping" section.
-- Demo: Improved "Layout & Scrolling" -> "Child Windows" section.
-- Style Editor: Added preview of circle auto-tessellation when editing the corresponding value.
-- Backends: OpenGL3: Added support for glad2 loader. (#3330) [@moritz-h]
-- Backends: Allegro 5: Fixed horizontal scrolling direction with mouse wheel / touch pads (it seems
- like Allegro 5 reports it differently from GLFW and SDL). (#3394, #2424, #1463) [@nobody-special666]
-- Examples: Vulkan: Fixed GLFW+Vulkan and SDL+Vulkan clear color not being set. (#3390) [@RoryO]
-- CI: Emscripten has stopped their support for their fastcomp backend, switching to latest sdk [@Xipiryon]

------------------------------------------------------------------------
- VERSION 1.77 (Released 2020-06-29)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.77
-
-Breaking Changes:
-
-- Removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular() function. Please
- note that this is a Beta api and will likely be reworked in order to support multi-DPI across
- multiple monitors.
-- Renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete).
- [NOTE: THIS WAS REVERTED IN 1.79]
-- Removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor
- of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.
- Kept inline redirection function (will obsolete).
-- Removed obsoleted CalcItemRectClosestPoint() entry point (has been asserting since December 2017).
-
-Other Changes:
-
-- TreeNode: Fixed bug where BeginDragDropSource() failed when the _OpenOnDoubleClick flag is
- enabled (bug introduced in 1.76, but pre-1.76 it would also fail unless the _OpenOnArrow
- flag was also set, and _OpenOnArrow is frequently set along with _OpenOnDoubleClick).
-- TreeNode: Fixed bug where dragging a payload over a TreeNode() with either _OpenOnDoubleClick
- or _OpenOnArrow would open the node. (#143)
-- Windows: Fix unintended feedback loops when resizing windows close to main viewport edges. [@rokups]
-- Tabs: Added style.TabMinWidthForUnselectedCloseButton settings:
- - Set to 0.0f (default) to always make a close button appear on hover (same as Chrome, VS).
- - Set to FLT_MAX to only display a close button when selected (merely hovering is not enough).
- - Set to an intermediary value to toggle behavior based on width (same as Firefox).
-- Tabs: Added a ImGuiTabItemFlags_NoTooltip flag to disable the tooltip for individual tab item
- (vs ImGuiTabBarFlags_NoTooltip for entire tab bar). [@Xipiryon]
-- Popups: All functions capable of opening popups (OpenPopup*, BeginPopupContext*) now take a new
- ImGuiPopupFlags sets of flags instead of a mouse button index. The API is automatically backward
- compatible as ImGuiPopupFlags is guaranteed to hold mouse button index in the lower bits.
-- Popups: Added ImGuiPopupFlags_NoOpenOverExistingPopup for OpenPopup*/BeginPopupContext* functions
- to first test for the presence of another popup at the same level.
-- Popups: Added ImGuiPopupFlags_NoOpenOverItems for BeginPopupContextWindow() - similar to testing
- for !IsAnyItemHovered() prior to doing an OpenPopup().
-- Popups: Added ImGuiPopupFlags_AnyPopupId and ImGuiPopupFlags_AnyPopupLevel flags for IsPopupOpen(),
- allowing to check if any popup is open at the current level, if a given popup is open at any popup
- level, if any popup is open at all.
-- Popups: Fix an edge case where programmatically closing a popup while clicking on its empty space
- would attempt to focus it and close other popups. (#2880)
-- Popups: Fix BeginPopupContextVoid() when clicking over the area made unavailable by a modal. (#1636)
-- Popups: Clarified some of the comments and function prototypes.
-- Modals: BeginPopupModal() doesn't set the ImGuiWindowFlags_NoSavedSettings flag anymore, and will
- not always be auto-centered. Note that modals are more similar to regular windows than they are to
- popups, so api and behavior may evolve further toward embracing this. (#915, #3091)
- Enforce centering using e.g. SetNextWindowPos(io.DisplaySize * 0.5f, ImGuiCond_Appearing, ImVec2(0.5f,0.5f)).
-- Metrics: Added a "Settings" section with some details about persistent ini settings.
-- Nav, Menus: Fix vertical wrap-around in menus or popups created with multiple appending calls to
- BeginMenu()/EndMenu() or BeginPopup(0/EndPopup(). (#3223, #1207) [@rokups]
-- Drag and Drop: Fixed unintended fallback "..." tooltip display during drag operation when
- drag source uses _SourceNoPreviewTooltip flags. (#3160) [@rokups]
-- Columns: Lower overhead on column switches and switching to background channel.
- Benefits Columns but was primarily made with Tables in mind!
-- Fonts: Fix GetGlyphRangesKorean() end-range to end at 0xD7A3 (instead of 0xD79D). (#348, #3217) [@marukrap]
-- ImDrawList: Fixed an issue where draw command merging or primitive unreserve while crossing the
- VtxOffset boundary would lead to draw commands with wrong VtxOffset. (#3129, #3163, #3232, #2591)
- [@thedmd, @Shironekoben, @sergeyn, @ocornut]
-- ImDrawList, ImDrawListSplitter, Columns: Fixed an issue where changing channels with different
- TextureId, VtxOffset would incorrectly apply new settings to draw channels. (#3129, #3163)
- [@ocornut, @thedmd, @Shironekoben]
-- ImDrawList, ImDrawListSplitter, Columns: Fixed an issue where starting a split when current
- VtxOffset was not zero would lead to draw commands with wrong VtxOffset. (#2591)
-- ImDrawList, ImDrawListSplitter, Columns: Fixed an issue where starting a split right after
- a callback draw command would incorrectly override the callback draw command.
-- Misc, Freetype: Fix for rare case where FT_Get_Char_Index() succeeds but FT_Load_Glyph() fails.
-- Docs: Improved and moved font documentation to docs/FONTS.md so it can be readable on the web.
- Updated various links/wiki accordingly. Added FAQ entry about DPI. (#2861) [@ButternCream, @ocornut]
-- CI: Added CI test to verify we're never accidentally dragging libstdc++ (on some compiler setups,
- static constructors for non-pod data seems to drag in libstdc++ due to thread-safety concerns).
- Fixed a static constructor which led to this dependency on some compiler setups. [@rokups]
-- Backends: Win32: Support for #define NOGDI, won't try to call GetDeviceCaps(). (#3137, #2327)
-- Backends: Win32: Fix _WIN32_WINNT < 0x0600 (MinGW defaults to 0x502 == Windows 2003). (#3183)
-- Backends: SDL: Report a zero display-size when window is minimized, consistent with other backends,
- making more render/clipping code use an early out path.
-- Backends: OpenGL: Fixed handling of GL 4.5+ glClipControl(GL_UPPER_LEFT) by inverting the
- projection matrix top and bottom values. (#3143, #3146) [@u3shit]
-- Backends: OpenGL: On OSX, if unspecified by app, made default GLSL version 150. (#3199) [@albertvaka]
-- Backends: OpenGL: Fixed loader auto-detection to not interfere with ES2/ES3 defines. (#3246) [@funchal]
-- Backends: Vulkan: Fixed error in if initial frame has no vertices. (#3177)
-- Backends: Vulkan: Fixed edge case where render callbacks wouldn't be called if the ImDrawData
- structure didn't have any vertices. (#2697) [@kudaba]
-- Backends: OSX: Added workaround to avoid fast mouse clicks. (#3261, #1992, #2525) [@nburrus]
-- Examples: GLFW+Vulkan, SDL+Vulkan: Fix for handling of minimized windows. (#3259)
-- Examples: Apple: Fixed example_apple_metal and example_apple_opengl2 using imgui_impl_osx.mm
- not forwarding right and center mouse clicks. (#3260) [@nburrus]

- VERSION 1.76 (Released 2020-04-12)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.76
-
-Other Changes:
-
-- Drag and Drop, Nav: Disabling navigation arrow keys when drag and drop is active. In the docking
- branch pressing arrow keys while dragging a window from a tab could trigger an assert. (#3025)
-- BeginMenu: Using same ID multiple times appends content to a menu. (#1207) [@rokups]
-- BeginMenu: Fixed a bug where SetNextWindowXXX data before a BeginMenu() would not be cleared
- when the menu is not open. (#3030)
-- InputText: Fixed password fields displaying ASCII spaces as blanks instead of using the '*'
- glyph. (#2149, #515)
-- Selectable: Fixed honoring style.SelectableTextAlign with unspecified size. (#2347, #2601)
-- Selectable: Allow using ImGuiSelectableFlags_SpanAllColumns in other columns than first. (#125)
-- TreeNode: Made clicking on arrow with _OpenOnArrow toggle the open state on the Mouse Down
- event rather than the Mouse Down+Up sequence (this is rather standard behavior).
-- ColorButton: Added ImGuiColorEditFlags_NoBorder flag to remove the border normally enforced
- by default for standalone ColorButton.
-- Nav: Fixed interactions with ImGuiListClipper, so e.g. Home/End result would not clip the
- landing item on the landing frame. (#787)
-- Nav: Fixed currently focused item from ever being clipped by ItemAdd(). (#787)
-- Scrolling: Fixed scrolling centering API leading to non-integer scrolling values and initial
- cursor position. This would often get fixed after the fix item submission, but using the
- ImGuiListClipper as the first thing after Begin() could largely break size calculations. (#3073)
-- Added optional support for Unicode plane 1-16 (#2538, #2541, #2815) [@cloudwu, @samhocevar]
- - Compile-time enable with '#define IMGUI_USE_WCHAR32' in imconfig.h.
- - More onsistent handling of unsupported code points (0xFFFD).
- - Surrogate pairs are supported when submitting UTF-16 data via io.AddInputCharacterUTF16(),
- allowing for more complete CJK input.
- - sizeof(ImWchar) goes from 2 to 4. IM_UNICODE_CODEPOINT_MAX goes from 0xFFFF to 0x10FFFF.
- - Various structures such as ImFont, ImFontGlyphRangesBuilder will use more memory, this
- is currently not particularly efficient.
-- Columns: undid the change in 1.75 were Columns()/BeginColumns() were preemptively limited
- to 64 columns with an assert. (#3037, #125)
-- Window: Fixed a bug with child window inheriting ItemFlags from their parent when the child
- window also manipulate the ItemFlags stack. (#3024) [@Stanbroek]
-- Font: Fixed non-ASCII space occasionally creating unnecessary empty looking polygons.
-- Misc: Added an explicit compile-time test for non-scoped IM_ASSERT() macros to redirect users
- to a solution rather than encourage people to add braces in the codebase.
-- Misc: Added additional checks in EndFrame() to verify that io.KeyXXX values have not been
- tampered with between NewFrame() and EndFrame().
-- Misc: Made default clipboard handlers for Win32 and OSX use a buffer inside the main context
- instead of a static buffer, so it can be freed properly on Shutdown. (#3110)
-- Misc, Freetype: Fixed support for IMGUI_STB_RECT_PACK_FILENAME compile time directive
- in imgui_freetype.cpp (matching support in the regular code path). (#3062) [@DonKult]
-- Metrics: Made Tools section more prominent. Showing wire-frame mesh directly hovering the ImDrawCmd
- instead of requiring to open it. Added options to disable bounding box and mesh display.
- Added notes on inactive/gc-ed windows.
-- Demo: Added black and white and color gradients to Demo>Examples>Custom Rendering.
-- CI: Added more tests on the continuous-integration server: extra warnings for Clang/GCC, building
- SDL+Metal example, building imgui_freetype.cpp, more compile-time imconfig.h settings: disabling
- obsolete functions, enabling 32-bit ImDrawIdx, enabling 32-bit ImWchar, disabling demo. [@rokups]
-- Backends: OpenGL3: Fixed version check mistakenly testing for GL 4.0+ instead of 3.2+ to enable
- ImGuiBackendFlags_RendererHasVtxOffset, leaving 3.2 contexts without it. (#3119, #2866) [@wolfpld]
-- Backends: OpenGL3: Added include support for older glbinding 2.x loader. (#3061) [@DonKult]
-- Backends: Win32: Added ImGui_ImplWin32_EnableDpiAwareness(), ImGui_ImplWin32_GetDpiScaleForHwnd(),
- ImGui_ImplWin32_GetDpiScaleForMonitor() helpers functions (backported from the docking branch).
- Those functions makes it easier for example apps to support hi-dpi features without setting up
- a manifest.
-- Backends: Win32: Calling AddInputCharacterUTF16() from WM_CHAR message handler in order to support
- high-plane surrogate pairs. (#2815) [@cloudwu, @samhocevar]
-- Backends: SDL: Added ImGui_ImplSDL2_InitForMetal() for API consistency (even though the function
- currently does nothing).
-- Backends: SDL: Fixed mapping for ImGuiKey_KeyPadEnter. (#3031) [@Davido71]
-- Examples: Win32+DX12: Fixed resizing main window, enabled debug layer. (#3087, #3115) [@sergeyn]
-- Examples: SDL+DX11: Fixed resizing main window. (#3057) [@joeslay]
-- Examples: Added SDL+Metal example application. (#3017) [@coding-jackalope]

------------------------------------------------------------------------
- VERSION 1.75 (Released 2020-02-10)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.75
-
-Breaking Changes:
-
-- Removed redirecting functions/enums names that were marked obsolete in 1.53 (December 2017):
- - ShowTestWindow() -> use ShowDemoWindow()
- - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow)
- - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)
- - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f)
- - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing()
- - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg
- - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding
- - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap
- - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS
- If you were still using the old names, while you are cleaning up, considering enabling
- IMGUI_DISABLE_OBSOLETE_FUNCTIONS in imconfig.h even temporarily to have a pass at finding
- and removing up old API calls, if any remaining.
-- Removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent
- with other mouse functions (none of the other functions have it).
-- Obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely
- documented and rarely if ever used). Instead we added an explicit PrimUnreserve() API
- which can be implemented faster. Also clarified pre-existing constraints which weren't
- documented (can only unreserve from the last reserve call). If you suspect you ever
- used that feature before (very unlikely, but grep for call to PrimReserve in your code),
- you can #define IMGUI_DEBUG_PARANOID in imconfig.h to catch existing calls. [@ShironekoBen]
-- ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius.
-- Limiting Columns()/BeginColumns() api to 64 columns with an assert. While the current code
- technically supports it, future code may not so we're putting the restriction ahead.
- [Undid that change in 1.76]
-- imgui_internal.h: changed ImRect() default constructor initializes all fields to 0.0f instead
- of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by
- adding points into it without explicit initialization, you may need to fix your initial value.
-
-Other Changes:
-
-- Inputs: Added ImGuiMouseButton enum for convenience (e.g. ImGuiMouseButton_Right=1).
- We forever guarantee that the existing value will not changes so existing code is free to use 0/1/2.
-- Nav: Fixed a bug where the initial CTRL-Tab press while in a child window sometimes selected
- the current root window instead of always selecting the previous root window. (#787)
-- ColorEdit: Fix label alignment when using ImGuiColorEditFlags_NoInputs. (#2955) [@rokups]
-- ColorEdit: In HSV display of a RGB stored value, attempt to locally preserve Saturation
- when Value==0.0 (similar to changes done in 1.73 for Hue). Removed Hue editing lock since
- those improvements in 1.73 makes them unnecessary. (#2722, #2770). [@rokups]
-- ColorEdit: "Copy As" context-menu tool shows hex values with a '#' prefix instead of '0x'.
-- ColorEdit: "Copy As" content-menu tool shows hex values both with/without alpha when available.
-- InputText: Fix corruption or crash when executing undo after clearing input with ESC, as a
- byproduct we are allowing to later undo the revert with a CTRL+Z. (#3008).
-- InputText: Fix using a combination of _CallbackResize (e.g. for std::string binding), along with the
- _EnterReturnsTrue flag along with the rarely used property of using an InputText without persisting
- user-side storage. Previously if you had e.g. a local unsaved std::string and reading result back
- from the widget, the user string object wouldn't be resized when Enter key was pressed. (#3009)
-- MenuBar: Fix minor clipping issue where occasionally a menu text can overlap the right-most border.
-- Window: Fix SetNextWindowBgAlpha(1.0f) failing to override alpha component. (#3007) [@Albog]
-- Window: When testing for the presence of the ImGuiWindowFlags_NoBringToFrontOnFocus flag we
- test both the focused/clicked window (which could be a child window) and the root window.
-- ImDrawList: AddCircle(), AddCircleFilled() API can now auto-tessellate when provided a segment
- count of zero. Alter tessellation quality with 'style.CircleSegmentMaxError'. [@ShironekoBen]
-- ImDrawList: Add AddNgon(), AddNgonFilled() API with a guarantee on the explicit segment count.
- In the current branch they are essentially the same as AddCircle(), AddCircleFilled() but as
- we will rework the circle rendering functions to use textures and automatic segment count
- selection, those new api can fill a gap. [@ShironekoBen]
-- Columns: ImDrawList::Channels* functions now work inside columns. Added extra comments to
- suggest using user-owned ImDrawListSplitter instead of ImDrawList functions. [@rokups]
-- Misc: Added ImGuiMouseCursor_NotAllowed enum so it can be used by more shared widgets. [@rokups]
-- Misc: Added IMGUI_DISABLE compile-time definition to make all headers and sources empty.
-- Misc: Disable format checks when using stb_printf, to allow using extra formats.
- Made IMGUI_USE_STB_SPRINTF a properly documented imconfig.h flag. (#2954) [@loicmolinari]
-- Misc: Added misc/single_file/imgui_single_file.h, We use this to validate compiling all *.cpp
- files in a same compilation unit. Actual users of that technique (also called "Unity builds")
- can generally provide this themselves, so we don't really recommend you use this. [@rokups]
-- CI: Added PVS-Studio static analysis on the continuous-integration server. [@rokups]
-- Backends: GLFW, SDL, Win32, OSX, Allegro: Added support for ImGuiMouseCursor_NotAllowed. [@rokups]
-- Backends: GLFW: Added support for the missing mouse cursors newly added in GLFW 3.4+. [@rokups]
-- Backends: SDL: Wayland: use SDL_GetMouseState (because there is no global mouse state available
- on Wayland). (#2800, #2802) [@NeroBurner]
-- Backends: GLFW, SDL: report Windows key (io.KeySuper) as always released. Neither GLFW nor SDL can
- correctly report the key release in every cases (e.g. when using Win+V) causing problems with some
- widgets. The next release of GLFW (3.4+) will have a fix for it. However since it is both difficult
- and discouraged to make use of this key for Windows application anyway, we just hide it. (#2976)
-- Backends: Win32: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD to disable all
- XInput using code, and IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT to disable linking with XInput,
- the later may be problematic if compiling with recent Windows SDK and you want your app to run
- on Windows 7. You can instead try linking with Xinput9_1_0.lib instead. (#2716)
-- Backends: Glut: Improved FreeGLUT support for MinGW. (#3004) [@podsvirov]
-- Backends: Emscripten: Avoid forcefully setting IMGUI_DISABLE_FILE_FUNCTIONS. (#3005) [@podsvirov]
-- Examples: OpenGL: Explicitly adding -DIMGUI_IMPL_OPENGL_LOADER_GL3W to Makefile to match linking
- settings (otherwise if another loader such as Glew is accessible, the OpenGL3 backend might
- automatically use it). (#2919, #2798)
-- Examples: OpenGL: Added support for glbinding OpenGL loader. (#2870) [@rokups]
-- Examples: Emscripten: Demonstrating embedding fonts in Makefile and code. (#2953) [@Oipo]
-- Examples: Metal: Wrapped main loop in @autoreleasepool block to ensure allocations get freed
- even if underlying system event loop gets paused due to app nap. (#2910, #2917) [@bear24rw]

------------------------------------------------------------------------
- VERSION 1.74 (Released 2019-11-25)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.74
-
-Breaking Changes:
-
-- Removed redirecting functions/enums names that were marked obsolete in 1.52 (October 2017):
- - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed
- - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)
- - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding()
- - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f)
- - ImFont::Glyph -> use ImFontGlyph
- If you were still using the old names, read "API Breaking Changes" section of imgui.cpp to find out
- the new names or equivalent features, or see how they were implemented until 1.73.
-- Inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used
- by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function.
- If you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can
- add +io.KeyRepeatDelay to it to compensate for the fix.
- The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0).
- Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay).
- Fixed the code and altered default io.KeyRepeatRate,Delay from 0.250,0.050 to 0.300,0.050 to compensate.
- If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you.
-- Misc: Renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS. (#1038)
-- Misc: Renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS.
-- Fonts: ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to
- conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert.
-- Backends: DX12: Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
- The value is unused in master branch but will be used by the multi-viewport feature. (#2851) [@obfuscate]
-
-Other Changes:
-
-- InputText, Nav: Fixed Home/End key broken when activating Keyboard Navigation. (#787)
-- InputText: Filter out ASCII 127 (DEL) emitted by low-level OSX layer, as we are using the Key value. (#2578)
-- Layout: Fixed a couple of subtle bounding box vertical positioning issues relating to the handling of text
- baseline alignment. The issue would generally manifest when laying out multiple items on a same line,
- with varying heights and text baseline offsets.
- Some specific examples, e.g. a button with regular frame padding followed by another item with a
- multi-line label and no frame padding, such as: multi-line text, small button, tree node item, etc.
- The second item was correctly offset to match text baseline, and would interact/display correctly,
- but it wouldn't push the contents area boundary low enough.
-- Scrollbar: Fixed an issue where scrollbars wouldn't display on the frame following a frame where
- all child window contents would be culled.
-- ColorPicker: Fixed SV triangle gradient to block (broken in 1.73). (#2864, #2711). [@lewa-j]
-- TreeNode: Fixed combination of ImGuiTreeNodeFlags_SpanFullWidth and ImGuiTreeNodeFlags_OpenOnArrow
- incorrectly locating the arrow hit position to the left of the frame. (#2451, #2438, #1897)
-- TreeNode: The collapsing arrow accepts click even if modifier keys are being held, facilitating
- interactions with custom multi-selections patterns. (#2886, #1896, #1861)
-- TreeNode: Added IsItemToggledOpen() to explicitly query if item was just open/closed, facilitating
- interactions with custom multi-selections patterns. (#1896, #1861)
-- DragScalar, SliderScalar, InputScalar: Added p_ prefix to parameter that are pointers to the data
- to clarify how they are used, and more comments redirecting to the demo code. (#2844)
-- Error handling: Assert if user mistakenly calls End() instead of EndChild() on a child window. (#1651)
-- Misc: Optimized storage of window settings data (reducing allocation count).
-- Misc: Windows: Do not use _wfopen() if IMGUI_DISABLE_WIN32_FUNCTIONS is defined. (#2815)
-- Misc: Windows: Disabled win32 function by default when building with UWP. (#2892, #2895)
-- Misc: Using static_assert() when using C++11, instead of our own construct (avoid zealous Clang warnings).
-- Misc: Added IMGUI_DISABLE_FILE_FUNCTIONS/IMGUI_DISABLE_DEFAULT_FILE_FUNCTION to nullify or disable
- default implementation of ImFileXXX functions linking with fopen/fclose/fread/fwrite. (#2734)
-- Docs: Improved and moved FAQ to docs/FAQ.md so it can be readable on the web. [@ButternCream, @ocornut]
-- Docs: Moved misc/fonts/README.txt to docs/FONTS.txt.
-- Docs: Added permanent redirect from https://www.dearimgui.com/faq to FAQ page.
-- Demo: Added simple item reordering demo in Widgets -> Drag and Drop section. (#2823, #143) [@rokups]
-- Metrics: Show wire-frame mesh and approximate surface area when hovering ImDrawCmd. [@ShironekoBen]
-- Metrics: Expose basic details of each window key/value state storage.
-- Examples: DX12: Using IDXGIDebug1::ReportLiveObjects() when DX12_ENABLE_DEBUG_LAYER is enabled.
-- Examples: Emscripten: Removed BINARYEN_TRAP_MODE=clamp from Makefile which was removed in Emscripten 1.39.0
- but required prior to 1.39.0, making life easier for absolutely no-one. (#2877, #2878) [@podsvirov]
-- Backends: OpenGL2: Explicitly backup, setup and restore GL_TEXTURE_ENV to increase compatibility with
- legacy OpenGL applications. (#3000)
-- Backends: OpenGL3: Fix building with pre-3.2 GL loaders which do not expose glDrawElementsBaseVertex(),
- using runtime GL version to decide if we set ImGuiBackendFlags_RendererHasVtxOffset. (#2866, #2852) [@dpilawa]
-- Backends: OSX: Fix using Backspace key. (#2578, #2817, #2818) [@DiligentGraphics]
-- Backends: GLFW: Previously installed user callbacks are now restored on shutdown. (#2836) [@malte-v]
-- CI: Set up a bunch of continuous-integration tests using GitHub Actions. We now compile many of the example
- applications on Windows, Linux, MacOS, iOS, Emscripten. Removed Travis integration. (#2865) [@rokups]

------------------------------------------------------------------------
- VERSION 1.73 (Released 2019-09-24)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.73
-
-Other Changes:
-
-- Nav, Scrolling: Added support for Home/End key. (#787)
-- ColorEdit: Disable Hue edit when Saturation==0 instead of letting Hue values jump around.
-- ColorEdit, ColorPicker: In HSV display of a RGB stored value, attempt to locally preserve Hue
- when Saturation==0, which reduces accidentally lossy interactions. (#2722, #2770) [@rokups]
-- ColorPicker: Made rendering aware of global style alpha of the picker can be faded out. (#2711)
- Note that some elements won't accurately fade down with the same intensity, and the color wheel
- when enabled will have small overlap glitches with (style.Alpha < 1.0).
-- Tabs: Fixed single-tab not shrinking their width down.
-- Tabs: Fixed clicking on a tab larger than tab-bar width creating a bouncing feedback loop.
-- Tabs: Feed desired width (sum of unclipped tabs width) into layout system to allow for auto-resize. (#2768)
- (before 1.71 tab bars fed the sum of current width which created feedback loops in certain situations).
-- Tabs: Improved shrinking for large number of tabs to avoid leaving extraneous space on the right side.
- Individuals tabs are given integer-rounded width and remainder is spread between tabs left-to-right.
-- Columns, Separator: Fixed a bug where non-visible separators within columns would alter the next row position
- differently than visible ones.
-- SliderScalar: Improved assert when using U32 or U64 types with a large v_max value. (#2765) [@loicmouton]
-- DragInt, DragFloat, DragScalar: Using (v_min > v_max) allows locking any edits to the value.
-- DragScalar: Fixed dragging of unsigned values on ARM cpu (float to uint cast is undefined). (#2780) [@dBagrat]
-- TreeNode: Added ImGuiTreeNodeFlags_SpanAvailWidth flag. (#2451, #2438, #1897) [@Melix19, @PathogenDavid]
- This extends the hit-box to the right-most edge, even if the node is not framed.
- (Note: this is not the default in order to allow adding other items on the same line. In the future we will
- aim toward refactoring the hit-system to be front-to-back, allowing more natural overlapping of items,
- and then we will be able to make this the default.)
-- TreeNode: Added ImGuiTreeNodeFlags_SpanFullWidth flag. This extends the hit-box to both the left-most and
- right-most edge of the working area, bypassing indentation.
-- CollapsingHeader: Added support for ImGuiTreeNodeFlags_Bullet and ImGuiTreeNodeFlags_Leaf on framed nodes,
- mostly for consistency. (#2159, #2160) [@goran-w]
-- Selectable: Added ImGuiSelectableFlags_AllowItemOverlap flag in public api (was previously internal only).
-- Style: Allow style.WindowMenuButtonPosition to be set to ImGuiDir_None to hide the collapse button. (#2634, #2639)
-- Font: Better ellipsis ("...") drawing implementation. Instead of drawing three pixel-ey dots (which was glaringly
- unfitting with many types of fonts) we first attempt to find a standard ellipsis glyphs within the loaded set.
- Otherwise we render ellipsis using '.' from the font from where we trim excessive spacing to make it as narrow
- as possible. (#2775) [@rokups]
-- ImDrawList: Clarified the name of many parameters so reading the code is a little easier. (#2740)
-- ImDrawListSplitter: Fixed merging channels if the last submitted draw command used a different texture. (#2506)
-- Using offsetof() when available in C++11. Avoids Clang sanitizer complaining about old-style macros. (#94)
-- ImVector: Added find(), find_erase(), find_erase_unsorted() helpers.
-- Added a mechanism to compact/free the larger allocations of unused windows (buffers are compacted when
- a window is unused for 60 seconds, as per io.ConfigWindowsMemoryCompactTimer = 60.0f). Note that memory
- usage has never been reported as a problem, so this is merely a touch of overzealous luxury. (#2636)
-- Documentation: Various tweaks and improvements to the README page. [@ker0chan]
-- Backends: OpenGL3: Tweaked initialization code allow application calling ImGui_ImplOpenGL3_CreateFontsTexture()
- before ImGui_ImplOpenGL3_NewFrame(), which sometimes can be convenient.
-- Backends: OpenGL3: Attempt to automatically detect default GL loader by using __has_include. (#2798) [@o-micron]
-- Backends: DX11: Fixed GSGetShader() call not passing an initialized instance count, which would
- generally make the DX11 debug layer complain (bug added in 1.72).
-- Backends: Vulkan: Added support for specifying multisample count. Set 'ImGui_ImplVulkan_InitInfo::MSAASamples' to
- one of the VkSampleCountFlagBits values to use, default is non-multisampled as before. (#2705, #2706) [@vilya]
-- Examples: OSX: Fix example_apple_opengl2/main.mm not forwarding mouse clicks and drags correctly. (#1961, #2710)
- [@intonarumori, @ElectricMagic]
-- Misc: Updated stb_rect_pack.h from 0.99 to 1.00 (fixes by @rygorous: off-by-1 bug in best-fit heuristic,
- fix handling of rectangles too large to fit inside texture). (#2762) [@tido64]

- VERSION 1.72b (Released 2019-07-31)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.72b
-
-Other Changes:
-
-- Nav, Scrolling: Fixed programmatic scroll leading to a slightly incorrect scroll offset when
- the window has decorations or a menu-bar (broken in 1.71). This was mostly noticeable when
- a keyboard/gamepad movement led to scrolling the view, or using e.g. SetScrollHereY() function.
-- Nav: Made hovering non-MenuItem Selectable not re-assign the source item for keyboard navigation.
-- Nav: Fixed an issue with NavFlattened window flag (beta) where widgets not entirely fitting
- in child window (often selectables because of their protruding sides) would be not considered
- as entry points to to navigate toward the child window. (#787)

------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.72
-
-Breaking Changes:
-
-- Removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017):
- - ImGuiCol_Column*, ImGuiSetCond_* enums.
- - IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow() functions.
- - IMGUI_ONCE_UPON_A_FRAME macro.
- If you were still using the old names, read "API Breaking Changes" section of imgui.cpp to find out
- the new names or equivalent features.
-- Renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete).
-- Removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()).
- Kept redirection function (will obsolete). (#581, #324)
-
-Other Changes:
-
-- Scrolling: Made mouse-wheel scrolling lock the underlying window until the mouse is moved again or
- until a short delay expires (~2 seconds). This allow uninterrupted scroll even if child windows are
- passing under the mouse cursor. (#2604)
-- Scrolling: Made it possible for mouse wheel and navigation-triggered scrolling to override a call to
- SetScrollX()/SetScrollY(), making it possible to use a simpler stateless pattern for auto-scrolling:
- // (Submit items..)
- if (ImGui::GetScrollY() >= ImGui::GetScrollMaxY()) // If scrolling at the already at the bottom..
- ImGui::SetScrollHereY(1.0f); // ..make last item fully visible
-- Scrolling: Added SetScrollHereX(), SetScrollFromPosX() for completeness. (#1580) [@kevreco]
-- Scrolling: Mouse wheel scrolling while hovering a child window is automatically forwarded to parent window
- if ScrollMax is zero on the scrolling axis.
- Also still the case if ImGuiWindowFlags_NoScrollWithMouse is set (not new), but previously the forwarding
- would be disabled if ImGuiWindowFlags_NoScrollbar was set on the child window, which is not the case
- any more. Forwarding can still be disabled by setting ImGuiWindowFlags_NoInputs. (amend #1502, #1380).
-- Window: Fixed InnerClipRect right-most coordinates using wrong padding setting (introduced in 1.71).
-- Window: Fixed old SetWindowFontScale() api value from not being inherited by child window. Added
- comments about the right way to scale your UI (load a font at the right side, rebuild atlas, scale style).
-- Scrollbar: Avoid overlapping the opposite side when window (often a child window) is forcibly too small.
-- Combo: Hide arrow when there's not enough space even for the square button.
-- InputText: Testing for newly added ImGuiKey_KeyPadEnter key. (#2677, #2005) [@amc522]
-- Tabs: Fixed unfocused tab bar separator color (was using ImGuiCol_Tab, should use ImGuiCol_TabUnfocusedActive).
-- Columns: Fixed a regression from 1.71 where the right-side of the contents rectangle within each column
- would wrongly use a WindowPadding.x instead of ItemSpacing.x like it always did. (#125, #2666)
-- Columns: Made the right-most edge reaches up to the clipping rectangle (removing half of WindowPadding.x
- worth of asymmetrical/extraneous padding, note that there's another half that conservatively has to offset
- the right-most column, otherwise it's clipping width won't match the other columns). (#125, #2666)
-- Columns: Improved honoring alignment with various values of ItemSpacing.x and WindowPadding.x. (#125, #2666)
-- Columns: Made GetColumnOffset() and GetColumnWidth() behave when there's no column set, consistently with
- other column functions. (#2683)
-- InputTextMultiline: Fixed vertical scrolling tracking glitch.
-- Word-wrapping: Fixed overzealous word-wrapping when glyph edge lands exactly on the limit. Because
- of this, auto-fitting exactly unwrapped text would make it wrap. (fixes initial 1.15 commit, 78645a7d).
-- Style: Attenuated default opacity of ImGuiCol_Separator in Classic and Light styles.
-- Style: Added style.ColorButtonPosition (left/right, defaults to ImGuiDir_Right) to move the color button
- of ColorEdit3/ColorEdit4 functions to either side of the inputs.
-- IO: Added ImGuiKey_KeyPadEnter and support in various backends (previously backends would need to
- specifically redirect key-pad keys to their regular counterpart). This is a temporary attenuating measure
- until we actually refactor and add whole sets of keys into the ImGuiKey enum. (#2677, #2005) [@amc522]
-- Misc: Made Button(), ColorButton() not trigger an "edited" event leading to IsItemDeactivatedAfterEdit()
- returning true. This also effectively make ColorEdit4() not incorrect trigger IsItemDeactivatedAfterEdit()
- when clicking the color button to open the picker popup. (#1875)
-- Misc: Added IMGUI_DISABLE_METRICS_WINDOW imconfig.h setting to explicitly compile out ShowMetricsWindow().
-- Debug Tools: Added "Metrics->Tools->Item Picker" tool which allow clicking on a widget to break in the
- debugger within the item code. The tool calls IM_DEBUG_BREAK() which can be redefined in imconfig.h.
-- ImDrawList: Fixed CloneOutput() helper crashing. (#1860) [@gviot]
-- ImDrawList::ChannelsSplit(), ImDrawListSplitter: Fixed an issue with merging draw commands between
- channel 0 and 1. (#2624)
-- ImDrawListSplitter: Fixed memory leak when using low-level split api (was not affecting ImDrawList api,
- also this type was added in 1.71 and not advertised as a public-facing feature).
-- Fonts: binary_to_compressed_c.cpp: Display an error message if failing to open/read the input font file.
-- Demo: Log, Console: Using a simpler stateless pattern for auto-scrolling.
-- Demo: Widgets: Showing how to use the format parameter of Slider/Drag functions to display the name
- of an enum value instead of the underlying integer value.
-- Demo: Renamed the "Help" menu to "Tools" (more accurate).
-- Backends: DX10/DX11: Backup, clear and restore Geometry Shader is any is bound when calling renderer.
-- Backends: DX11: Clear Hull Shader, Domain Shader, Compute Shader before rendering. Not backing/restoring them.
-- Backends: OSX: Disabled default native Mac clipboard copy/paste implementation in core library (added in 1.71),
- because it needs application to be linked with '-framework ApplicationServices'. It can be explicitly
- enabled back by using '#define IMGUI_ENABLE_OSX_DEFAULT_CLIPBOARD_FUNCTIONS' in imconfig.h. Re-added
- equivalent using NSPasteboard api in the imgui_impl_osx.mm experimental backend. (#2546)
-- Backends: SDL2: Added ImGui_ImplSDL2_InitForD3D() function to make D3D support more visible.
- (#2482, #2632) [@josiahmanson]
-- Examples: Added SDL2+DirectX11 example application. (#2632, #2612, #2482) [@vincenthamm]

------------------------------------------------------------------------
- VERSION 1.71 (Released 2019-06-12)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.71
-
-Breaking Changes:
-
-- IO: changed AddInputCharacter(unsigned short c) signature to AddInputCharacter(unsigned int c).
-- Renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
-- Window: rendering of child windows outer decorations (e.g. bg color, border, scrollbars) is now
- performed as part of their parent window, avoiding the creation of an extraneous draw commands.
- If you have overlapping child windows with decorations, and relied on their relative z-order to be
- mapped to submission their order, this will affect your rendering. The optimization is disabled
- if the parent window has no visual output because it appears to be the most common situation leading
- to the creation of overlapping child windows. Please reach out if you are affected by this change!
-
-Other Changes:
-
-- Window: clarified behavior of SetNextWindowContentSize(). Content size is defined as the size available
- after removal of WindowPadding on each sides. So SetNextWindowContentSize(ImVec2(100,100)) + auto-resize
- will always allow submitting a 100x100 item without creating a scrollbar, regarding of WindowPadding.
- The exact meaning of ContentSize for decorated windows was previously ill-defined.
-- Window: Fixed auto-resize with AlwaysVerticalScrollbar or AlwaysHorizontalScrollbar flags.
-- Window: Fixed one case where auto-resize by double-clicking the resize grip would make either scrollbar
- appear for a single frame after the resize.
-- Separator: Revert 1.70 "Declare its thickness (1.0f) to the layout" change. It's not incorrect
- but it breaks existing some layout patterns. Will return back to it when we expose Separator flags.
-- Fixed InputScalar, InputScalarN, SliderScalarN, DragScalarN with non-visible label from inserting
- style.ItemInnerSpacing.x worth of trailing spacing.
-- Fixed InputFloatX, SliderFloatX, DragFloatX functions erroneously reporting IsItemEdited() multiple
- times when the text input doesn't match the formatted output value (e.g. input "1" shows "1.000").
- It wasn't much of a problem because we typically use the return value instead of IsItemEdited() here.
-- Fixed uses of IsItemDeactivated(), IsItemDeactivatedAfterEdit() on multi-components widgets and
- after EndGroup(). (#2550, #1875)
-- Fixed crash when appending with BeginMainMenuBar() more than once and no other window are showing. (#2567)
-- ColorEdit: Fixed the color picker popup only displaying inputs as HSV instead of showing multiple
- options. (#2587, broken in 1.69 by #2384).
-- CollapsingHeader: Better clipping when a close button is enabled and it overlaps the label. (#600)
-- Scrollbar: Minor bounding box adjustment to cope with various border size.
-- Scrollbar, Style: Changed default style.ScrollbarSize from 16 to 14.
-- Combo: Fixed rounding not applying with the ImGuiComboFlags_NoArrowButton flag. (#2607) [@DucaRii]
-- Nav: Fixed gamepad/keyboard moving of window affecting contents size incorrectly, sometimes leading
- to scrollbars appearing during the movement.
-- Nav: Fixed rare crash when e.g. releasing Alt-key while focusing a window with a menu at the same
- frame as clearing the focus. This was in most noticeable in backends such as Glfw and SDL which
- emits key release events when focusing another viewport, leading to Alt+clicking on void on another
- viewport triggering the issue. (#2609)
-- TreeNode, CollapsingHeader: Fixed highlight frame not covering horizontal area fully when using
- horizontal scrolling. (#2211, #2579)
-- Tabs: Fixed BeginTabBar() within a window with horizontal scrolling from creating a feedback
- loop with the horizontal contents size.
-- Columns: Fixed Columns() within a window with horizontal scrolling from not covering the full
- horizontal area (previously only worked with an explicit contents size). (#125)
-- Columns: Fixed Separator from creating an extraneous draw command. (#125)
-- Columns: Fixed Selectable with SpanAllColumns flag from creating an extraneous draw command. (#125)
-- Style: Added style.WindowMenuButtonPosition (left/right, defaults to ImGuiDir_Left) to move the
- collapsing/docking button to the other side of the title bar.
-- Style: Made window close button cross slightly smaller.
-- Log/Capture: Fixed BeginTabItem() label not being included in a text log/capture.
-- ImDrawList: Added ImDrawCmd::VtxOffset value to support large meshes (64k+ vertices) using 16-bit indices.
- The renderer backend needs to set 'io.BackendFlags |= ImGuiBackendFlags_RendererHasVtxOffset' to enable
- this, and honor the ImDrawCmd::VtxOffset field. Otherwise the value will always be zero. (#2591)
- This has the advantage of preserving smaller index buffers and allowing to execute on hardware that do not
- support 32-bit indices. Most examples backends have been modified to support the VtxOffset field.
-- ImDrawList: Added ImDrawCmd::IdxOffset value, equivalent to summing element count for each draw command.
- This is provided for convenience and consistency with VtxOffset. (#2591)
-- ImDrawCallback: Allow to override the signature of ImDrawCallback by #define-ing it. This is meant to
- facilitate custom rendering backends passing local render-specific data to the draw callback.
-- ImFontAtlas: FreeType: Added RasterizerFlags::Monochrome flag to disable font anti-aliasing. Combine
- with RasterizerFlags::MonoHinting for best results. (#2545) [@HolyBlackCat]
-- ImFontGlyphRangesBuilder: Fixed unnecessarily over-sized buffer, which incidentally was also not
- fully cleared. Fixed edge-case overflow when adding character 0xFFFF. (#2568). [@NIKE3500]
-- Demo: Added full "Dear ImGui" prefix to the title of "Dear ImGui Demo" and "Dear ImGui Metrics" windows.
-- Backends: Add native Mac clipboard copy/paste default implementation in core library to match what we are
- dealing with Win32, and to facilitate integration in custom engines. (#2546) [@andrewwillmott]
-- Backends: OSX: imgui_impl_osx: Added mouse cursor support. (#2585, #1873) [@actboy168]
-- Examples/Backends: DirectX9/10/11/12, Metal, Vulkan, OpenGL3 (Desktop GL only): Added support for large meshes
- (64k+ vertices) with 16-bit indices, enable 'ImGuiBackendFlags_RendererHasVtxOffset' in those backends. (#2591)
-- Examples/Backends: Don't filter characters under 0x10000 before calling io.AddInputCharacter(),
- the filtering is done in io.AddInputCharacter() itself. This is in prevision for fuller Unicode
- support. (#2538, #2541)
-

------------------------------------------------------------------------
- VERSION 1.70 (Released 2019-05-06)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.70
-
-Breaking Changes:
-
-- ImDrawList: Improved algorithm for mitre joints on thick lines, preserving correct thickness
- up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines,
- they will appear a little thicker now. (#2518) [@rmitton]
-- Obsoleted GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead.
- Kept inline redirection function.
-- Examples: Vulkan: Added MinImageCount/ImageCount fields in ImGui_ImplVulkan_InitInfo, required
- during initialization to specify the number of in-flight image requested by swap chains.
- (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). (#2071, #1677) [@nathanvoglsam]
-- Examples: Vulkan: Tidying up the demo/internals helpers (most engine/app should not rely
- on them but it is possible you have!).
-
-Other Changes:
-
-- ImDrawList: Added ImDrawCallback_ResetRenderState, a special ImDrawList::AddCallback() value
- to request the renderer backend to reset its render state. (#2037, #1639, #2452)
- Examples: Added support for ImDrawCallback_ResetRenderState in all renderer backends. Each
- renderer code setting up initial render state has been moved to a function so it could be
- called at the start of rendering and when a ResetRenderState is requested. [@ocornut, @bear24rw]
-- InputText: Fixed selection background rendering one frame after the cursor movement when
- first transitioning from no-selection to has-selection. (Bug in 1.69) (#2436) [@Nazg-Gul]
-- InputText: Work-around for buggy standard libraries where isprint('\t') returns true. (#2467, #1336)
-- InputText: Fixed ImGuiInputTextFlags_AllowTabInput leading to two tabs characters being inserted
- if the backend provided both Key and Character input. (#2467, #1336)
-- Layout: Added SetNextItemWidth() helper to avoid using PushItemWidth/PopItemWidth() for single items.
- Note that SetNextItemWidth() currently only affect the same subset of items as PushItemWidth(),
- generally referred to as the large framed+labeled items. Because the new SetNextItemWidth()
- function is explicit we may later extend its effect to more items.
-- Layout: Fixed PushItemWidth(-width) for right-side alignment laying out some items (button, listbox, etc.)
- with negative sizes if the 'width' argument was smaller than the available width at the time of item
- submission.
-- Window: Fixed window with the AlwaysAutoResize flag unnecessarily extending their hovering boundaries
- by a few pixels (this is used to facilitate resizing from borders when available for a given window).
- One of the noticeable minor side effect was that navigating menus would have had a tendency to disable
- highlight from parent menu items earlier than necessary while approaching the child menu.
-- Window: Close button is horizontally aligned with style.FramePadding.x.
-- Window: Fixed contents region being off by WindowBorderSize amount on the right when scrollbar is active.
-- Window: Fixed SetNextWindowSizeConstraints() with non-rounded positions making windows drift. (#2067, #2530)
-- Popups: Closing a popup restores the focused/nav window in place at the time of the popup opening,
- instead of restoring the window that was in the window stack at the time of the OpenPopup call. (#2517)
- Among other things, this allows opening a popup while no window are focused, and pressing Escape to
- clear the focus again.
-- Popups: Fixed right-click from closing all popups instead of aiming at the hovered popup level
- (regression in 1.67).
-- Selectable: With ImGuiSelectableFlags_AllowDoubleClick doesn't return true on the mouse button release
- following the double-click. Only first mouse release + second mouse down (double-click) returns true.
- Likewise for internal ButtonBehavior() with both _PressedOnClickRelease | _PressedOnDoubleClick. (#2503)
-- GetMouseDragDelta(): also returns the delta on the mouse button released frame. (#2419)
-- GetMouseDragDelta(): verify that mouse positions are valid otherwise returns zero.
-- Inputs: Also add support for horizontal scroll with Shift+Mouse Wheel. (#2424, #1463) [@LucaRood]
-- PlotLines, PlotHistogram: Ignore NaN values when calculating min/max bounds. (#2485)
-- Columns: Fixed boundary of clipping being off by 1 pixel within the left column. (#125)
-- Separator: Declare its thickness (1.0f) to the layout, making items around separator more symmetrical.
-- Combo, Slider, Scrollbar: Improve rendering in situation when there's only a few pixels available (<3 pixels).
-- Nav: Fixed Drag/Slider functions going into text input mode when keyboard CTRL is held while pressing NavActivate.
-- Drag and Drop: Fixed drag source with ImGuiDragDropFlags_SourceAllowNullID and null ID from receiving click
- regardless of being covered by another window (it didn't honor correct hovering rules). (#2521)
-- ImDrawList: Improved algorithm for mitre joints on thick lines, preserving correct thickness up to 90 degrees
- angles, also faster to output. (#2518) [@rmitton]
-- Misc: Added IM_MALLOC/IM_FREE macros mimicking IM_NEW/IM_DELETE so user doesn't need to revert
- to using the ImGui::MemAlloc()/MemFree() calls directly.
-- Misc: Made IMGUI_CHECKVERSION() macro also check for matching size of ImDrawIdx.
-- Metrics: Added "Show windows rectangles" tool to visualize the different rectangles.
-- Demo: Improved trees in columns demo.
-- Examples: OpenGL: Added a test GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized
- GL function loaders early, and help users understand what they are missing. (#2421)
-- Examples: SDL: Added support for SDL_GameController gamepads (enable with ImGuiConfigFlags_NavEnableGamepad). (#2509) [@DJLink]
-- Examples: Emscripten: Added Emscripten+SDL+GLES2 example. (#2494, #2492, #2351, #336) [@nicolasnoble, @redblobgames]
-- Examples: Metal: Added Glfw+Metal example. (#2527) [@bear24rw]
-- Examples: OpenGL3: Minor tweaks + not calling glBindBuffer more than necessary in the render loop.
-- Examples: Vulkan: Fixed in-flight buffers issues when using multi-viewports. (#2461, #2348, #2378, #2097)
-- Examples: Vulkan: Added missing support for 32-bit indices (#define ImDrawIdx unsigned int).
-- Examples: Vulkan: Avoid passing negative coordinates to vkCmdSetScissor, which debug validation layers do not like.
-- Examples: Vulkan: Added ImGui_ImplVulkan_SetMinImageCount() to change min image count at runtime. (#2071) [@nathanvoglsam]
-- Examples: DirectX9: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects(). (#2454)
-- Examples: DirectX10/11/12, Allegro, Marmalade: Render functions early out when display size is zero (minimized). (#2496)
-- Examples: GLUT: Fixed existing FreeGLUT example to work with regular GLUT. (#2465) [@andrewwillmott]
-- Examples: GLUT: Renamed imgui_impl_freeglut.cpp/.h to imgui_impl_glut.cpp/.h. (#2465) [@andrewwillmott]
-- Examples: GLUT: Made io.DeltaTime always > 0. (#2430)
-- Examples: Visual Studio: Updated default platform toolset+sdk in vcproj files from v100+sdk7 (vs2010)
- to v110+sdk8 (vs2012). This is mostly so we can remove reliance on DXSDK_DIR for the DX10/DX11 example,
- which if existing and when switching to recent SDK ends up conflicting and creating warnings.

------------------------------------------------------------------------
- VERSION 1.69 (Released 2019-03-13)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.69
-
-Breaking Changes:
-
-- Renamed ColorEdit/ColorPicker's ImGuiColorEditFlags_RGB/_HSV/_HEX flags to respectively
- ImGuiColorEditFlags_DisplayRGB/_DisplayHSV/_DisplayHex. This is because the addition of
- new flag ImGuiColorEditFlags_InputHSV makes the earlier one ambiguous.
- Kept redirection enum values (will obsolete). (#2384) [@haldean]
-- Renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). (#2391)
-
-Other Changes:
-
-- Added GetBackgroundDrawList() helper to quickly get access to a ImDrawList that will be rendered
- behind every other windows. (#2391, #545)
-- DragScalar, InputScalar, SliderScalar: Added support for u8/s8/u16/s16 data types (ImGuiDataType_S8, etc.)
- We are reusing function instances of larger types to reduce code size. (#643, #320, #708, #1011)
-- Added InputTextWithHint() to display a description/hint in the text box when no text
- has been entered. (#2400) [@Organic-Code, @ocornut]
-- Nav: Fixed a tap on AltGR (e.g. German keyboard) from navigating to the menu layer.
-- Nav: Fixed Ctrl+Tab keeping active InputText() of a previous window active after the switch. (#2380)
-- Fixed IsItemDeactivated()/IsItemDeactivatedAfterEdit() from not correctly returning true
- when tabbing out of a focusable widget (Input/Slider/Drag) in most situations. (#2215, #1875)
-- InputInt, InputFloat, InputScalar: Fix to keep the label of the +/- buttons centered when
- style.FramePadding.x is abnormally larger than style.FramePadding.y. Since the buttons are
- meant to be square (to align with e.g. color button) we always use FramePadding.y. (#2367)
-- InputInt, InputScalar: +/- buttons now respects the natural type limits instead of
- overflowing or underflowing the value.
-- InputText: Fixed an edge case crash that would happen if another widget sharing the same ID
- is being swapped with an InputText that has yet to be activated.
-- InputText: Fixed various display corruption related to swapping the underlying buffer while
- a input widget is active (both for writable and read-only paths). Often they would manifest
- when manipulating the scrollbar of a multi-line input text.
-- ColorEdit, ColorPicker, ColorButton: Added ImGuiColorEditFlags_InputHSV to manipulate color
- values encoded as HSV (in order to avoid HSV<>RGB round trips and associated singularities).
- (#2383, #2384) [@haldean]
-- ColorPicker: Fixed a bug/assertion when displaying a color picker in a collapsed window
- while dragging its title bar. (#2389)
-- ColorEdit: Fixed tooltip not honoring the ImGuiColorEditFlags_NoAlpha contract of never
- reading the 4th float in the array (value was read and discarded). (#2384) [@haldean]
-- MenuItem, Selectable: Fixed disabled widget interfering with navigation (fix c2db7f63 in 1.67).
-- Tabs: Fixed a crash when using many BeginTabBar() recursively (didn't affect docking). (#2371)
-- Tabs: Added extra mis-usage error recovery. Past the assert, common mis-usage don't lead to
- hard crashes any more, facilitating integration with scripting languages. (#1651)
-- Tabs: Fixed ImGuiTabItemFlags_SetSelected being ignored if the tab is not visible (with
- scrolling policy enabled) or if is currently appearing.
-- Tabs: Fixed Tab tooltip code making drag and drop tooltip disappear during the frame where
- the drag payload activate a tab.
-- Tabs: Reworked scrolling policy (when ImGuiTabBarFlags_FittingPolicyScroll is set) to
- teleport the view when aiming at a tab far away the visible section, and otherwise accelerate
- the scrolling speed to cap the scrolling time to 0.3 seconds.
-- Text: Fixed large Text/TextUnformatted calls not feeding their size into layout when starting
- below the lower point of the current clipping rectangle. This bug has been there since v1.0!
- It was hardly noticeable but would affect the scrolling range, which in turn would affect
- some scrolling request functions when called during the appearing frame of a window.
-- Plot: Fixed divide-by-zero in PlotLines() when passing a count of 1. (#2387) [@Lectem]
-- Log/Capture: Fixed LogXXX functions emitting extraneous leading carriage return.
-- Log/Capture: Fixed an issue when empty string on a new line would not emit a carriage return.
-- Log/Capture: Fixed LogXXX functions 'auto_open_depth' parameter being treated as an absolute
- tree depth instead of a relative one.
-- Log/Capture: Fixed CollapsingHeader trailing ascii representation being "#" instead of "##".
-- ImFont: Added GetGlyphRangesVietnamese() helper. (#2403)
-- Misc: Asserting in NewFrame() if style.WindowMinSize is zero or smaller than (1.0f,1.0f).
-- Demo: Using GetBackgroundDrawList() and GetForegroundDrawList() in "Custom Rendering" demo.
-- Demo: InputText: Demonstrating use of ImGuiInputTextFlags_CallbackResize. (#2006, #1443, #1008).
-- Examples: GLFW, SDL: Preserve DisplayFramebufferScale when main viewport is minimized.
- (This is particularly useful for the viewport branch because we are not supporting per-viewport
- frame-buffer scale. It fixes windows not refreshing when main viewport is minimized.) (#2416)
-- Examples: OpenGL: Fix to be able to run on ES 2.0 / WebGL 1.0. [@rmitton, @gabrielcuvillier]
-- Examples: OpenGL: Fix for OSX not supporting OpenGL 4.5, we don't try to read GL_CLIP_ORIGIN
- even if the OpenGL headers/loader happens to define the value. (#2366, #2186)
-- Examples: Allegro: Added support for touch events (emulating mouse). (#2219) [@dos1]
-- Examples: DirectX9: Minor changes to match the other DirectX examples more closely. (#2394)

------------------------------------------------------------------------
- VERSION 1.68 (Released 2019-02-19)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.68
-
-Breaking Changes:
-
-- Removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).
-- Made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame).
- If for some reason your time step calculation gives you a zero value, replace it with a arbitrarily small value!
-
-Other Changes:
-
-- Added .editorconfig file for text editors to standardize using spaces. (#2038) [@kudaba]
-- ImDrawData: Added FramebufferScale field (currently a copy of the value from io.DisplayFramebufferScale).
- This is to allow render functions being written without pulling any data from ImGuiIO, allowing incoming
- multi-viewport feature to behave on Retina display and with multiple displays.
- If you are not using a custom backend, please update your render function code ahead of time,
- and use draw_data->FramebufferScale instead of io.DisplayFramebufferScale. (#2306, #1676)
-- Added IsItemActivated() as an extension to the IsItemDeactivated/IsItemDeactivatedAfterEdit functions
- which are useful to implement variety of undo patterns. (#820, #956, #1875)
-- InputText: Fixed a bug where ESCAPE would not restore the initial value in all situations. (#2321) [@relick]
-- InputText: Fixed a bug where ESCAPE would be first captured by the Keyboard Navigation code. (#2321, #787)
-- InputText: Fixed redo buffer exhaustion handling (rare) which could corrupt the undo character buffer. (#2333)
- The way the redo/undo buffers work would have made it generally unnoticeable to the user.
-- Fixed range-version of PushID() and GetID() not honoring the ### operator to restart from the seed value.
-- Fixed CloseCurrentPopup() on a child-menu of a modal incorrectly closing the modal. (#2308)
-- Tabs: Added ImGuiTabBarFlags_TabListPopupButton flag to show a popup button on manual tab bars. (#261, #351)
-- Tabs: Removed ImGuiTabBarFlags_NoTabListPopupButton which was available in 1.67 but actually had zero use.
-- Tabs: Fixed a minor clipping glitch when changing style's FramePadding from frame to frame.
-- Tabs: Fixed border (when enabled) so it is aligned correctly mid-pixel and appears as bright as other borders.
-- Style, Selectable: Added ImGuiStyle::SelectableTextAlign and ImGuiStyleVar_SelectableTextAlign. (#2347) [@haldean]
-- Menus: Tweaked horizontal overlap between parent and child menu (to help convey relative depth)
- from using style.ItemSpacing.x to style.ItemInnerSpacing.x, the later being expected to be smaller. (#1086)
-- RadioButton: Fixed label horizontal alignment to precisely match Checkbox().
-- Window: When resizing from an edge, the border is more visible and better follow the rounded corners.
-- Window: Fixed initial width of collapsed windows not taking account of contents width (broken in 1.67). (#2336, #176)
-- Scrollbar: Fade out and disable interaction when too small, in order to facilitate using the resize grab on very
- small window, as well as reducing visual noise/overlap.
-- ListBox: Better optimized when clipped / non-visible.
-- InputTextMultiline: Better optimized when clipped / non-visible.
-- Font: Fixed high-level ImGui::CalcTextSize() used by most widgets from erroneously subtracting 1.0f*scale to
- calculated text width. Among noticeable side-effects, it would make sequences of repeated Text/SameLine calls
- not align the same as a single call, and create mismatch between high-level size calculation and those performed
- with the lower-level ImDrawList api. (#792) [@SlNPacifist]
-- Font: Fixed building atlas when specifying duplicate/overlapping ranges within a same font. (#2353, #2233)
-- ImDrawList: Fixed AddCircle(), AddCircleFilled() angle step being off, which was visible when drawing a "circle"
- with a small number of segments (e.g. an hexagon). (#2287) [@baktery]
-- ImGuiTextBuffer: Added append() function (unformatted).
-- ImFontAtlas: Added 0x2000-0x206F general punctuation range to default ChineseFull/ChineseSimplifiedCommon ranges. (#2093)
-- ImFontAtlas: FreeType: Added support for imgui allocators + custom FreeType only SetAllocatorFunctions. (#2285) [@Vuhdo]
-- ImFontAtlas: FreeType: Fixed using imgui_freetype.cpp in unity builds. (#2302)
-- Demo: Fixed "Log" demo not initializing properly, leading to the first line not showing before a Clear. (#2318) [@bluescan]
-- Demo: Added "Auto-scroll" option in Log/Console demos. (#2300) [@nicolasnoble, @ocornut]
-- Examples: Metal, OpenGL2, OpenGL3, Vulkan: Fixed offsetting of clipping rectangle with ImDrawData::DisplayPos != (0,0)
- when the display frame-buffer scale scale is not (1,1). While this doesn't make a difference when using master branch,
- this is effectively fixing support for multi-viewport with Mac Retina Displays on those examples. (#2306) [@rasky, @ocornut]
- Also using ImDrawData::FramebufferScale instead of io.DisplayFramebufferScale.
-- Examples: Clarified the use the ImDrawData::DisplayPos to offset clipping rectangles.
-- Examples: Win32: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created
- in a different thread or parent. (#1951, #2087, #2156, #2232) [many people]
-- Examples: SDL: Using the SDL_WINDOW_ALLOW_HIGHDPI flag. (#2306, #1676) [@rasky]
-- Examples: Win32: Added support for XInput gamepads (if ImGuiConfigFlags_NavEnableGamepad is enabled).
-- Examples: Win32: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages. (#2264)
-- Examples: DirectX9: Explicitly disable fog (D3DRS_FOGENABLE) before drawing in case user state has it set. (#2288, #2230)
-- Examples: OpenGL2: Added #define GL_SILENCE_DEPRECATION to cope with newer XCode warnings.
-- Examples: OpenGL3: Using GLSL 4.10 shaders for any GLSL version over 410 (e.g. 430, 450). (#2329) [@BrutPitt]

- VERSION 1.67 (Released 2019-01-14)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.67
-
-Breaking Changes:
-
-- Made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable
- side-effect because the window would have ID zero. In particular it is causing problems in viewport/docking branches.
-- Renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges and removed its [Beta] mark.
- The addition of new configuration options in the Docking branch is pushing for a little reorganization of those names.
-- Renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete).
-
-Other Changes:
-- Added BETA api for Tab Bar/Tabs widgets: (#261, #351)
- - Added BeginTabBar(), EndTabBar(), BeginTabItem(), EndTabItem(), SetTabItemClosed() API.
- - Added ImGuiTabBarFlags flags for BeginTabBar().
- - Added ImGuiTabItemFlags flags for BeginTabItem().
- - Style: Added ImGuiCol_Tab, ImGuiCol_TabHovered, ImGuiCol_TabActive, ImGuiCol_TabUnfocused, ImGuiCol_TabUnfocusedActive colors.
- - Demo: Added Layout->Tabs demo code.
- - Demo: Added "Documents" example app showcasing possible use for tabs.
- This feature was merged from the Docking branch in order to allow the use of regular tabs in your code.
- (It does not provide the docking/splitting/merging of windows available in the Docking branch)
-- Added ImGuiWindowFlags_UnsavedDocument window flag to append '*' to title without altering the ID, as a convenience
- to avoid using the ### operator. In the Docking branch this also has an effect on tab closing behavior.
-- Window, Focus, Popup: Fixed an issue where closing a popup by clicking another window with the _NoMove flag would refocus
- the parent window of the popup instead of the newly clicked window.
-- Window: Contents size is preserved while a window collapsed. Fix auto-resizing window losing their size for one frame when uncollapsed.
-- Window: Contents size is preserved while a window contents is hidden (unless it is hidden for resizing purpose).
-- Window: Resizing windows from edge is now enabled by default (io.ConfigWindowsResizeFromEdges=true). Note that
- it only works _if_ the backend sets ImGuiBackendFlags_HasMouseCursors, which the standard backends do.
-- Window: Added io.ConfigWindowsMoveFromTitleBarOnly option. This is ignored by window with no title bars (often popups).
- This affects clamping window within the visible area: with this option enabled title bars need to be visible. (#899)
-- Window: Fixed using SetNextWindowPos() on a child window (which wasn't really documented) position the cursor as expected
- in the parent window, so there is no mismatch between the layout in parent and the position of the child window.
-- InputFloat: When using ImGuiInputTextFlags_ReadOnly the step buttons are disabled. (#2257)
-- DragFloat: Fixed broken mouse direction change with power!=1.0. (#2174, #2206) [@Joshhua5]
-- Nav: Fixed an keyboard issue where holding Activate/Space for longer than two frames on a button would unnecessary
- keep the focus on the parent window, which could steal it from newly appearing windows. (#787)
-- Nav: Fixed animated window titles from being updated when displayed in the CTRL+Tab list. (#787)
-- Error recovery: Extraneous/undesired calls to End() are now being caught by an assert in the End() function closer
- to the user call site (instead of being reported in EndFrame). Past the assert, they don't lead to crashes any more. (#1651)
- Missing calls to End(), past the assert, should not lead to crashes or to the fallback Debug window appearing on screen.
- Those changes makes it easier to integrate dear imgui with a scripting language allowing, given asserts are redirected
- into e.g. an error log and stopping the script execution.
-- ImFontAtlas: Stb and FreeType: Atlas width is now properly based on total surface rather than glyph count (unless overridden with TexDesiredWidth).
-- ImFontAtlas: Stb and FreeType: Fixed atlas builder so missing glyphs won't influence the atlas texture width. (#2233)
-- ImFontAtlas: Stb and FreeType: Fixed atlas builder so duplicate glyphs (when merging fonts) won't be included in the rasterized atlas.
-- ImFontAtlas: FreeType: Fixed abnormally high atlas height.
-- ImFontAtlas: FreeType: Fixed support for any values of TexGlyphPadding (not just only 1).
-- ImDrawList: Optimized some of the functions for performance of debug builds where non-inline function call cost are non-negligible.
- (Our test UI scene on VS2015 Debug Win64 with /RTC1 went ~5.9 ms -> ~4.9 ms. In Release same scene stays at ~0.3 ms.)
-- IO: Added BackendPlatformUserData, BackendRendererUserData, BackendLanguageUserData void* for storage use by backends.
-- IO: Renamed InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!
-- IO: AddInputCharacter() goes into a queue which can receive as many characters as needed during the frame. This is useful
- for automation to not have an upper limit on typing speed. Will later transition key/mouse to use the event queue later.
-- Style: Tweaked default value of style.DisplayWindowPadding from (20,20) to (19,19) so the default style as a value
- which is the same as the title bar height.
-- Demo: "Simple Layout" and "Style Editor" are now using tabs.
-- Demo: Added a few more things under "Child windows" (changing ImGuiCol_ChildBg, positioning child, using IsItemHovered after a child).
-- Examples: DirectX10/11/12: Made imgui_impl_dx10/dx11/dx12.cpp link d3dcompiler.lib from the .cpp file to ease integration.
-- Examples: Allegro 5: Properly destroy globals on shutdown to allow for restart. (#2262) [@DomRe]

- VERSION 1.66b (Released 2018-12-01)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.66b
-
-Other Changes:
-
-- Fixed a text rendering/clipping bug introduced in 1.66 (on 2018-10-12, commit ede3a3b9) that affect single ImDrawList::AddText()
- calls with single strings larger than 10k. Text/TextUnformatted() calls were not affected, but e.g. InputText() was. [@pdoane]
-- When the focused window become inactive don't restore focus to a window with the ImGuiWindowFlags_NoInputs flag. (#2213) [@zzzyap]
-- Separator: Fixed Separator() outputting an extraneous empty line when captured into clipboard/text/file.
-- Demo: Added ShowAboutWindow() call, previously was only accessible from the demo window.
-- Demo: ShowAboutWindow() now display various Build/Config Information (compiler, os, etc.) that can easily be copied into bug reports.
-- Fixed build issue with osxcross and macOS. (#2218) [@dos1]
-- Examples: Setting up 'io.BackendPlatformName'/'io.BackendRendererName' fields to the current backend can be displayed in the About window.
-- Examples: SDL: changed the signature of ImGui_ImplSDL2_ProcessEvent() to use a const SDL_Event*. (#2187)

------------------------------------------------------------------------
- VERSION 1.66 (Released 2018-11-22)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.66
-
-Breaking Changes:
-
-- Renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).
-- Renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. (#2035, #2096)
-
-Other Changes:
-
-- Fixed calling SetNextWindowSize()/SetWindowSize() with non-integer values leading to
- accidental alteration of window position. We now round the provided size. (#2067)
-- Fixed calling DestroyContext() always saving .ini data with the current context instead
- of the supplied context pointer. (#2066)
-- Nav, Focus: Fixed ImGuiWindowFlags_NoBringToFrontOnFocus windows not being restoring focus
- properly after the main menu bar or last focused window is deactivated.
-- Nav: Fixed an assert in certain circumstance (mostly when using popups) when mouse positions stop being valid. (#2168)
-- Nav: Fixed explicit directional input not re-highlighting current nav item if there is a single item in the window
- and highlight has been previously disabled by the mouse. (#787)
-- DragFloat: Fixed a situation where dragging with value rounding enabled or with a power curve
- erroneously wrapped the value to one of the min/max edge. (#2024, #708, #320, #2075).
-- DragFloat: Disabled using power curve when one edge is FLT_MAX (broken in 1.61). (#2024)
-- DragFloat: Disabled setting a default drag speed when one edge is FLT_MAX. (#2024)
-- SliderAngle: Added optional format argument to alter precision or localize the string. (#2150) [@podsvirov]
-- Window: Resizing from edges (with io.ConfigResizeWindowsFromEdges Beta flag) extends the hit region
- of root floating windows outside the window, making it easier to resize windows. Resize grips are also
- extended accordingly so there are no discontinuity when hovering between borders and corners. (#1495, #822)
-- Window: Added ImGuiWindowFlags_NoBackground flag to avoid rendering window background. This is mostly to allow
- the creation of new flag combinations, as we could already use SetNextWindowBgAlpha(0.0f). (#1660) [@biojppm, @ocornut]
-- Window: Added ImGuiWindowFlags_NoDecoration helper flag which is essentially NoTitleBar+NoResize+NoScrollbar+NoCollapse.
-- Window: Added ImGuiWindowFlags_NoMouseInputs which is basically the old ImGuiWindowFlags_NoInputs (essentially
- we have renamed ImGuiWindowFlags_NoInputs to ImGuiWindowFlags_NoMouseInputs). Made the new ImGuiWindowFlags_NoInputs
- encompass both NoMouseInputs+NoNav, which is consistent with its description. (#1660, #787)
-- Window, Inputs: Fixed resizing from edges when io.MousePos is not pixel-rounded by rounding mouse position input. (#2110)
-- BeginChild(): Fixed BeginChild(const char*, ...) variation erroneously not applying the ID stack
- to the provided string to uniquely identify the child window. This was undoing an intentional change
- introduced in 1.50 and broken in 1.60. (#1698, #894, #713).
-- TextUnformatted(): Fixed a case where large-text path would read bytes past the text_end marker depending
- on the position of new lines in the buffer (it wasn't affecting the output but still not the right thing to do!)
-- ListBox(): Fixed frame sizing when items_count==1 unnecessarily showing a scrollbar. (#2173) [@luk1337, @ocornut]
-- ListBox(): Tweaked frame sizing so list boxes will look more consistent when FramePadding is far from ItemSpacing.
-- RenderText(): Some optimization for very large text buffers, useful for non-optimized builds.
-- BeginMenu(): Fixed menu popup horizontal offset being off the item in the menu bar when WindowPadding=0.0f.
-- ArrowButton(): Fixed arrow shape being horizontally misaligned by (FramePadding.y-FramePadding.x) if they are different.
-- Demo: Split the contents of ShowDemoWindow() into smaller functions as it appears to speed up link time with VS. (#2152)
-- Drag and Drop: Added GetDragDropPayload() to peek directly into the payload (if any) from anywhere. (#143)
-- ImGuiTextBuffer: Avoid heap allocation when empty.
-- ImDrawList: Fixed AddConvexPolyFilled() undefined behavior when passing points_count smaller than 3,
- in particular, points_count==0 could lead to a memory stomp if the draw list was previously empty.
-- Examples: DirectX10, DirectX11: Removed seemingly unnecessary calls to invalidate and recreate device objects
- in the WM_SIZE handler. (#2088) [@ice1000]
-- Examples: GLFW: User previously installed GLFW callbacks are now saved and chain-called by the default callbacks. (#1759)
-- Examples: OpenGL3: Added support for GL 4.5's glClipControl(GL_UPPER_LEFT). (#2186)
-- Examples: OpenGL3+GLFW: Fixed error condition when using the GLAD loader. (#2157) [@blackball]
-- Examples: OpenGL3+GLFW/SDL: Made main.cpp compile with IMGUI_IMPL_OPENGL_LOADER_CUSTOM (may be missing init). (#2178) [@doug-moen]
-- Examples: SDL2+Vulkan: Fixed application shutdown which could deadlock on Linux + Xorg. (#2181) [@eRabbit0]

- VERSION 1.65 (Released 2018-09-06)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.65
-
-Breaking Changes:
-
-- Renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and
- stb_rect_pack.h to imstb_rectpack.h. If you were conveniently using the imgui copy of those
- STB headers in your project, you will have to update your include paths. (#1718, #2036)
- The reason for this change is to avoid conflicts for projects that may also be importing
- their own copy of the STB libraries. Note that imgui's copy of stb_textedit.h is modified.
-- Renamed io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
-
-Other Changes:
-
-- This is a minor release following the 1.64 refactor, with a little more shuffling of code.
-- Clarified and improved the source code sectioning in all files (easier to search or browse sections).
-- Nav: Removed the [Beta] tag from various descriptions of the gamepad/keyboard navigation system.
- Although it is not perfect and will keep being improved, it is fairly functional and used by many. (#787)
-- Fixed a build issue with non-Cygwin GCC under Windows.
-- Demo: Added a "Configuration" block to make io.ConfigFlags/io.BackendFlags more prominent.
-- Examples: OpenGL3+SDL2: Fixed error condition when using the GLAD loader. (#2059, #2002) [@jiri]
-
-
------------------------------------------------------------------------
- VERSION 1.64 (Released 2018-08-31)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.64
-
-Changes:
-
-- Moved README, CHANGELOG and TODO files to the docs/ folder.
- If you are updating dear imgui by copying files, take the chance to delete the old files.
-- Added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp.
- Re-ordered some of the code remaining in imgui.cpp.
- NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTIONS HAS BEEN MOVED.
- Because of this, any local modifications to imgui.cpp will likely conflict when you update.
- If you have any modifications to imgui.cpp, it is suggested that you first update to 1.63, then
- isolate your patches. You can peak at imgui_widgets.cpp from 1.64 to get a sense of what is included in it,
- then separate your changes into several patches that can more easily be applied to 1.64 on a per-file basis.
- What I found worked nicely for me, was to open the diff of the old patches in an interactive merge/diff tool,
- search for the corresponding function in the new code and apply the chunks manually.
-- As a reminder, if you have any change to imgui.cpp it is a good habit to discuss them on the github,
- so a solution applicable on the Master branch can be found. If your company has changes that you cannot
- disclose you may also contact me privately.

------------------------------------------------------------------------
- VERSION 1.63 (Released 2018-08-29)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.63
-
-Breaking Changes:
-
-- Style: Renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features.
- Kept redirection enum (will obsolete).
-- Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecision over time.
-- Removed per-window ImGuiWindowFlags_ResizeFromAnySide Beta flag in favor `io.ConfigResizeWindowsFromEdges=true` to
- enable the feature globally. (#1495)
- The feature is not currently enabled by default because it is not satisfying enough, but will eventually be.
-- InputText: Renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData
- for consistency. Kept redirection types (will obsolete).
-- InputText: Removed ImGuiTextEditCallbackData::ReadOnly because it is a duplication of (::Flags & ImGuiInputTextFlags_ReadOnly).
-- Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API.
- Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
-- Renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to
- io.ConfigMacOSXBehaviors for consistency. (#1427, #473)
-- Removed obsolete redirection functions: CollapsingHeader() variation with 2 bools - marked obsolete in v1.49, May 2016.
-
-Other Changes:
-
-- ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat).
-- ArrowButton: Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly.
-- Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. The change is motivated by upcoming
- Docking features. (#787)
-- Nav: Made CTRL+TAB skip menus + skip the current navigation window if is has the ImGuiWindow_NoNavFocus set. (#787)
- While it was previously possible, you won't be able to CTRL-TAB out and immediately back in a window with the
- ImGuiWindow_NoNavFocus flag.
-- Window: Allow menu and popups windows from ignoring the style.WindowMinSize values so short menus/popups are not padded. (#1909)
-- Window: Added global io.ConfigResizeWindowsFromEdges option to enable resizing windows from their edges and from
- the lower-left corner. (#1495)
-- Window: Collapse button shows hovering highlight + clicking and dragging on it allows to drag the window as well.
-- Added IsItemEdited() to query if the last item modified its value (or was pressed). This is equivalent to the bool
- returned by most widgets.
- It is useful in some situation e.g. using InputText() with ImGuiInputTextFlags_EnterReturnsTrue. (#2034)
-- InputText: Added support for buffer size/capacity changes via the ImGuiInputTextFlags_CallbackResize flag. (#2006, #1443, #1008).
-- InputText: Fixed not tracking the cursor horizontally when modifying the text buffer through a callback.
-- InputText: Fixed minor off-by-one issue when submitting a buffer size smaller than the initial zero-terminated buffer contents.
-- InputText: Fixed a few pathological crash cases on single-line InputText widget with multiple millions characters worth of contents.
- Because the current text drawing function reserve for a worst-case amount of vertices and how we handle horizontal clipping,
- we currently just avoid displaying those single-line widgets when they are over a threshold of 2 millions characters,
- until a better solution is found.
-- Drag and Drop: Fixed an incorrect assert when dropping a source that is submitted after the target (bug introduced with 1.62 changes
- related to the addition of IsItemDeactivated()). (#1875, #143)
-- Drag and Drop: Fixed ImGuiDragDropFlags_SourceNoDisableHover to affect hovering state prior to calling IsItemHovered() + fixed description. (#143)
-- Drag and Drop: Calling BeginTooltip() between a BeginDragSource()/EndDragSource() or BeginDropTarget()/EndDropTarget() uses adjusted tooltip
- settings matching the one created when calling BeginDragSource() without the ImGuiDragDropFlags_SourceNoPreviewTooltip flag. (#143)
-- Drag and Drop: Payload stays available and under the mouse if the source stops being submitted, however the tooltip is replaced by "...". (#1725)
-- Drag and Drop: Added ImGuiDragDropFlags_SourceAutoExpirePayload flag to force payload to expire if the source stops being submitted. (#1725, #143).
-- IsItemHovered(): Added ImGuiHoveredFlags_AllowWhenDisabled flag to query hovered status on disabled items. (#1940, #211)
-- Selectable: Added ImGuiSelectableFlags_Disabled flag in the public API. (#211)
-- ColorEdit4: Fixed a bug when text input or drag and drop leading to unsaturated HSV values would erroneously alter the resulting color. (#2050)
-- Misc: Added optional misc/stl/imgui_stl.h wrapper to use with STL types (e.g. InputText with std::string). (#2006, #1443, #1008)
- [*EDIT* renamed to misc/std/imgui_stdlib.h in 1.66]
-- Misc: Added IMGUI_VERSION_NUM for easy compile-time testing. (#2025)
-- Misc: Added ImGuiMouseCursor_Hand cursor enum + corresponding software cursor. (#1913, 1914) [@aiekick, @ocornut]
-- Misc: Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors.
-- Made assertion more clear when trying to call Begin() outside of the NewFrame()..EndFrame() scope. (#1987)
-- Fixed assertion when transitioning from an active ID to another within a group, affecting ColorPicker (broken in 1.62). (#2023, #820, #956, #1875).
-- Fixed PushID() from keeping alive the new ID Stack top value (if a previously active widget shared the ID it would be erroneously kept alive).
-- Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502)
-- Fixed a include build issue for Cygwin in non-POSIX (Win32) mode. (#1917, #1319, #276)
-- ImDrawList: Improved handling for worst-case vertices reservation policy when large amount of text (e.g. 1+ million character strings)
- are being submitted in a single call. It would typically have crashed InputTextMultiline(). (#200)
-- OS/Windows: Fixed missing ImmReleaseContext() call in the default Win32 IME handler. (#1932) [@vby]
-- Metrics: Changed io.MetricsActiveWindows to reflect the number of active windows (!= from visible windows), which is useful
- for lazy/idle render mechanisms as new windows are typically not visible for one frame.
-- Metrics: Added io.MetricsRenderWindow to reflect the number of visible windows.
-- Metrics: Added io.MetricsActiveAllocations, moving away from the cross-context global counters than we previously used. (#1565, #1599, #586)
-- Demo: Added basic Drag and Drop demo. (#143)
-- Demo: Modified the Console example to use InsertChars() in the input text callback instead of poking directly into the buffer.
- Although this won't make a difference in the example itself, using InsertChars() will honor the resizing callback properly. (#2006, #1443, #1008).
-- Demo: Clarified the use of IsItemHovered()/IsItemActive() right after being in the "Active, Focused, Hovered & Focused Tests" section.
-- Examples: Tweaked the main.cpp of each example.
-- Examples: Metal: Added Metal rendering backend. (#1929, #1873) [@warrenm]
-- Examples: OSX: Added early raw OSX platform backend. (#1873) [@pagghiu, @itamago, @ocornut]
-- Examples: Added mac OSX & iOS + Metal example in example_apple_metal/. (#1929, #1873) [@warrenm]
-- Examples: Added mac OSX + OpenGL2 example in example_apple_opengl2/. (#1873)
-- Examples: OpenGL3: Added shaders more versions of GLSL. (#1938, #1941, #1900, #1513, #1466, etc.)
-- Examples: OpenGL3: Tweaked the imgui_impl_opengl3.cpp to work as-is with Emscripten + WebGL 2.0. (#1941). [@o-micron]
-- Examples: OpenGL3: Made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac.
-- Examples: OpenGL3: Added error output when shaders fail to compile/link.
-- Examples: OpenGL3: Added support for glew and glad OpenGL loaders out of the box. (#2001, #2002) [@jdumas]
-- Examples: OpenGL2: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications. (#1996)
-- Examples: DirectX10, DirectX11: Fixed unreleased resources in Init and Shutdown functions. (#1944)
-- Examples: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility. (#1989) [@matt77hias]
-- Examples: Vulkan: Fixed handling of VkSurfaceCapabilitiesKHR::maxImageCount = 0 case. Tweaked present mode selections.
-- Examples: Win32, Glfw, SDL: Added support for the ImGuiMouseCursor_Hand cursor.

- VERSION 1.62 (Released 2018-06-22)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.62
-
-Breaking Changes:
-
-- TreeNodeEx(): The helper ImGuiTreeNodeFlags_CollapsingHeader flag now include ImGuiTreeNodeFlags_NoTreePushOnOpen.
- The flag was already set by CollapsingHeader().
- The only difference is if you were using TreeNodeEx() manually with ImGuiTreeNodeFlags_CollapsingHeader and without
- ImGuiTreeNodeFlags_NoTreePushOnOpen. In this case you can remove the ImGuiTreeNodeFlags_NoTreePushOnOpen flag from
- your call (ImGuiTreeNodeFlags_CollapsingHeader & ~ImGuiTreeNodeFlags_NoTreePushOnOpen). (#1864)
- This also apply if you were using internal's TreeNodeBehavior() with the ImGuiTreeNodeFlags_CollapsingHeader flag directly.
-- ImFontAtlas: Renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish new smaller variants and
- discourage using the full set. (#1859)
-
-Other Changes:
-
-- Examples backends have been refactored to separate the platform code (e.g. Win32, Glfw, SDL2) from the renderer code (e.g. DirectX11, OpenGL3, Vulkan).
- The "Platform" backends are in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, etc.
- The "Renderer" backends are in charge of: creating the main font texture, rendering imgui draw data.
- before: imgui_impl_dx11.cpp --> after: imgui_impl_win32.cpp + imgui_impl_dx11.cpp
- before: imgui_impl_dx12.cpp --> after: imgui_impl_win32.cpp + imgui_impl_dx12.cpp
- before: imgui_impl_glfw_gl3.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_opengl2.cpp
- before: imgui_impl_glfw_vulkan.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_vulkan.cpp
- before: imgui_impl_sdl_gl3.cpp --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl2.cpp
- before: imgui_impl_sdl_gl3.cpp --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl3.cpp etc.
- - The idea is what we can now easily combine and maintain backends and reduce code redundancy. Individual files are
- smaller and more reusable. Integration of imgui into a new/custom engine may also be easier as there is less overlap
- between "windowing / inputs" and "rendering" code, so you may study or grab one half of the code and not the other.
- - This change was motivated by the fact that adding support for the upcoming multi-viewport feature requires more work
- from the Platform and Renderer backends, and the amount of redundancy across files was becoming too difficult to
- maintain. If you use default backends, you'll benefit from an easy update path to support multi-viewports later
- (for future ImGui 1.7x).
- - This is not strictly a breaking change if you keep your old backends, but when you'll want to fully update your backends,
- expect to have to reshuffle a few things.
- - Each example still has its own main.cpp which you may refer you to understand how to initialize and glue everything together.
- - Some frameworks (such as the Allegro, Marmalade) handle both the "platform" and "rendering" part, and your custom engine may as well.
- - Read examples/README.txt for details.
-- Added IsItemDeactivated() to query if the last item was active previously and isn't anymore. Useful for Undo/Redo patterns. (#820, #956, #1875)
-- Added IsItemDeactivatedAfterChange() [*EDIT* renamed to IsItemDeactivatedAfterEdit() in 1.63] if the last item was active previously,
- is not anymore, and during its active state modified a value. Note that you may still get false positive (e.g. drag value and while
- holding return on the same value). (#820, #956, #1875)
-- Nav: Added support for PageUp/PageDown (explorer-style: first aim at bottom/top most item, when scroll a page worth of contents). (#787)
-- Nav: To keep the navigated item in view we also attempt to scroll the parent window as well as the current window. (#787)
-- ColorEdit3, ColorEdit4, ColorButton: Added ImGuiColorEditFlags_NoDragDrop flag to disable ColorEditX as drag target and ColorButton as drag source. (#1826)
-- BeginDragDropSource(): Offset tooltip position so it is off the mouse cursor, but also closer to it than regular tooltips,
- and not clamped by viewport. (#1739)
-- BeginDragDropTarget(): Added ImGuiDragDropFlags_AcceptNoPreviewTooltip flag to request hiding the drag source tooltip
- from the target site. (#143)
-- BeginCombo(), BeginMainMenuBar(), BeginChildFrame(): Temporary style modification are restored at the end of BeginXXX
- instead of EndXXX, to not affect tooltips and child windows.
-- Popup: Improved handling of (erroneously) repeating calls to OpenPopup() to not close the popup's child popups. (#1497, #1533, #1865).
-- InputTextMultiline(): Fixed double navigation highlight when scrollbar is active. (#787)
-- InputText(): Fixed Undo corruption after pasting large amount of text (Redo will still fail when undo buffers are exhausted,
- but text won't be corrupted).
-- SliderFloat(): When using keyboard/gamepad and a zero precision format string (e.g. "%.0f"), always step in integer units. (#1866)
-- ImFontConfig: Added GlyphMinAdvanceX/GlyphMaxAdvanceX settings useful to make a font appears monospaced, particularly useful
- for icon fonts. (#1869)
-- ImFontAtlas: Added GetGlyphRangesChineseSimplifiedCommon() helper that returns a list of ~2500 most common Simplified Chinese
- characters. (#1859) [@JX-Master, @ocornut]
-- Examples: OSX: Added imgui_impl_osx.mm backend to be used along with e.g. imgui_impl_opengl2.cpp. (#281, #1870) [@pagghiu, @itamago, @ocornut]
-- Examples: GLFW: Made it possible to Shutdown/Init the backend again (by resetting the time storage properly). (#1827) [@ice1000]
-- Examples: Win32: Fixed handling of mouse wheel messages to support sub-unit scrolling messages (typically sent by track-pads). (#1874) [@zx64]
-- Examples: SDL+Vulkan: Added SDL+Vulkan example.
-- Examples: Allegro5: Added support for ImGuiConfigFlags_NoMouseCursorChange flag. Added clipboard support.
-- Examples: Allegro5: Unindexing buffers ourselves as Allegro indexed drawing primitives are buggy in the DirectX9 backend
- (will be fixed in Allegro 5.2.5+).
-- Examples: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from ImGui_ImplDX12_NewFrame() to ImGui_ImplDX12_RenderDrawData() which makes a lots more sense. (#301)
-- Examples: Vulkan: Reordered parameters ImGui_ImplVulkan_RenderDrawData() to be consistent with other backends,
- a good occasion since we refactored the code.
-- Examples: FreeGLUT: Added FreeGLUT backends. Added FreeGLUT+OpenGL2 example. (#801)
-- Examples: The functions in imgui_impl_xxx.cpp are prefixed with IMGUI_IMPL_API (which defaults to IMGUI_API) to facilitate
- some uses. (#1888)
-- Examples: Fixed backends to use ImGuiMouseCursor_COUNT instead of old name ImGuiMouseCursor_Count_ so they can compile
- with IMGUI_DISABLE_OBSOLETE_FUNCTIONS. (#1887)
-- Misc: Updated stb_textedit from 1.09 + patches to 1.12 + minor patches.
-- Internals: PushItemFlag() flags are inherited by BeginChild().

- VERSION 1.61 (Released 2018-05-14)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.61
-
-Breaking Changes:
-
-- DragInt(): The default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally
- any more. If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
- To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d,
- giving time to users to upgrade their code.
- If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your
- codebase for e.g. "DragInt.*%f" to you find them.
-- InputFloat(): Obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more
- flexible "const char* format", consistent with other functions. Kept redirection functions (will obsolete).
-- Misc: IM_DELETE() helper function added in 1.60 doesn't set the input pointer to NULL, more consistent with standard
- expectation and allows passing r-values.
-
-Other Changes:
-
-- Added DragScalar, DragScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011)
-- Added InputScalar, InputScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011)
-- Added SliderScalar, SliderScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011)
-- Window: Fixed pop-ups/tooltips/menus not honoring style.DisplaySafeAreaPadding as well as it should have (part of menus
- displayed outside the safe area, etc.).
-- Window: Fixed windows using the ImGuiWindowFlags_NoSavedSettings flag from not using the same default position as other windows. (#1760)
-- Window: Relaxed the internal stack size checker to allow Push/Begin/Pop/.../End patterns to be used with PushStyleColor, PushStyleVar, PushFont without causing a false positive assert. (#1767)
-- Window: Fixed the default proportional item width lagging by one frame on resize.
-- Columns: Fixed a bug introduced in 1.51 where columns would affect the contents size of their container, often creating
- feedback loops when ImGuiWindowFlags_AlwaysAutoResize was used. (#1760)
-- Settings: Fixed saving an empty .ini file if CreateContext/DestroyContext are called without a single call to NewFrame(). (#1741)
-- Settings: Added LoadIniSettingsFromDisk(), LoadIniSettingsFromMemory(), SaveIniSettingsToDisk(), SaveIniSettingsToMemory()
- to manually load/save .ini settings. (#923, #993)
-- Settings: Added io.WantSaveIniSettings flag, which is set to notify the application that e.g. SaveIniSettingsToMemory()
- should be called. (#923, #993)
-- Scrolling: Fixed a case where using SetScrollHere(1.0f) at the bottom of a window on the same frame the window height
- has been growing would have the scroll clamped using the previous height. (#1804)
-- MenuBar: Made BeginMainMenuBar() honor style.DisplaySafeAreaPadding so the text can be made visible on TV settings that
- don't display all pixels. (#1439) [@dougbinks]
-- InputText: On Mac OS X, filter out characters when the CMD modifier is held. (#1747) [@sivu]
-- InputText: On Mac OS X, support CMD+SHIFT+Z for Redo. CMD+Y is also supported as major apps seems to default to support both. (#1765) [@lfnoise]
-- InputText: Fixed returning true when edition is cancelled with ESC and the current buffer matches the initial value.
-- InputFloat,InputFloat2,InputFloat3,InputFloat4: Added variations taking a more flexible and consistent optional
- "const char* format" parameter instead of "int decimal_precision". This allow using custom formats to display values
- in scientific notation, and is generally more consistent with other API.
- Obsoleted functions using the optional "int decimal_precision" parameter. (#648, #712)
-- DragFloat, DragInt: Cancel mouse tweak when current value is initially past the min/max boundaries and mouse is pushing
- in the same direction (keyboard/gamepad version already did this).
-- DragFloat, DragInt: Honor natural type limits (e.g. INT_MAX, FLT_MAX) instead of wrapping around. (#708, #320)
-- DragFloat, SliderFloat: Fixes to allow input of scientific notation numbers when using CTRL+Click to input the value. (~#648, #1011)
-- DragFloat, SliderFloat: Rounding-on-write uses the provided format string instead of parsing the precision from the string,
- which allows for finer uses of %e %g etc. (#648, #642)
-- DragFloat: Improved computation when using the power curve. Improved lost of input precision with very small steps.
- Added an assert than power-curve requires a min/max range. (~#642)
-- DragFloat: The 'power' parameter is only honored if the min/max parameter are also setup.
-- DragInt, SliderInt: Fixed handling of large integers (we previously passed data around internally as float, which reduced
- the range of valid integers).
-- ColorEdit: Fixed not being able to pass the ImGuiColorEditFlags_NoAlpha or ImGuiColorEditFlags_HDR flags to SetColorEditOptions().
-- Nav: Fixed hovering a Selectable() with the mouse so that it update the navigation cursor (as it happened in the pre-1.60 navigation branch). (#787)
-- Style: Changed default style.DisplaySafeAreaPadding values from (4,4) to (3,3) so it is smaller than FramePadding and has no effect on main menu bar on a computer. (#1439)
-- Fonts: When building font atlas, glyphs that are missing in the fonts are not using the glyph slot to render the default glyph. Saves space and allow merging fonts with
- overlapping font ranges such as FontAwesome5 which split out the Brands separately from the Solid fonts. (#1703, #1671)
-- Misc: Added IMGUI_CHECKVERSION() macro to compare version string and data structure sizes in order to catch issues with mismatching compilation unit settings. (#1695, #1769)
-- Misc: Added IMGUI_DISABLE_MATH_FUNCTIONS in imconfig.h to make it easier to redefine wrappers for std/crt math functions.
-- Misc: Fix to allow compiling in unity builds where stb_rectpack/stb_truetype may be already included in the same compilation unit.
-- Demo: Simple Overlay: Added a context menu item to enable freely moving the window.
-- Demo: Added demo for DragScalar(), InputScalar(), SliderScalar(). (#643)
-- Examples: Calling IMGUI_CHECKVERSION() in the main.cpp of every example application.
-- Examples: Allegro 5: Added support for 32-bit indices setup via defining ImDrawIdx, to avoid an unnecessary conversion (Allegro 5 doesn't support 16-bit indices).
-- Examples: Allegro 5: Renamed backend from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
-- Examples: DirectX 9: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud. (#1790, #1687) [@sr-tream]
-- Examples: SDL: Fixed clipboard paste memory leak in the SDL backend code. (#1803) [@eliasdaler]
-- Various minor fixes, tweaks, refactoring, comments.

------------------------------------------------------------------------
- VERSION 1.60 (Released 2018-04-07)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.60
-
-The gamepad/keyboard navigation branch (which has been in the work since July 2016) has been merged.
-Gamepad/keyboard navigation is still marked as Beta and has to be enabled explicitly.
-Various internal refactoring have also been done, as part of the navigation work and as part of the upcoming viewport/docking work.
-
-Breaking Changes:
-
-- Obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render().
- e.g. with example backends, call ImDrawData* draw_data = ImGui::GetDrawData(); ImGui_ImplXXXX_RenderDrawData(draw_data).
-- Reorganized context handling to be more explicit: (#1599)
- - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
- - removed Shutdown() function, as DestroyContext() serve this purpose. If you are using an old backend from the examples/ folder, remove the line that calls Shutdown().
- - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance.
- - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
- - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
-- Renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
-- Fonts: Moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
-- Fonts: Changed ImFont::DisplayOffset.y to defaults to 0 instead of +1. Fixed vertical rounding of Ascent/Descent to match TrueType renderer.
- If you were adding or subtracting (not assigning) to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. (#1619)
-- BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
-- Obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
-- Obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
-- Renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, not used by core, and honored by some backend ahead of merging the Nav branch).
-- Removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered style colors as the closing cross uses regular button colors now.
-- Renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
-- Removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it should be easy to replicate on your side (you can find the code in 1.53).
-- [EDITED] Window: BeginChild() with an explicit name doesn't include the hash within the internal window name. (#1698)
- This change was erroneously introduced, undoing the change done for #894, #713, and not documented properly in the original
- 1.60 release Changelog. It was fixed on 2018-09-28 (1.66) and I wrote this paragraph the same day.
-
-Other Changes:
-
-- Doc: Added a Changelog file in the repository to ease comparing versions (it goes back to dear imgui 1.48), until now it was only on GitHub.
-- Navigation: merged in the gamepad/keyboard navigation (about a million changes!). (#787, #323)
- The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
-- To use Gamepad Navigation:
- - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
- - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame(). Read imgui.cpp for more details.
- - See https://github.com/ocornut/imgui/issues/1599 for recommended gamepad mapping or download PNG/PSD at http://goo.gl/9LgVZW
- - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. Read imgui.cpp for more details.
-- To use Keyboard Navigation:
- - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable. NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays.
- - Basic controls: arrows to navigate, Alt to enter menus, Space to activate item, Enter to edit text, Escape to cancel/close, Ctrl-Tab to focus windows, etc.
- - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag will be set.
- For more advanced uses, you may want to read from io.NavActive or io.NavVisible. Read imgui.cpp for more details.
-- Navigation: SetItemDefaultFocus() sets the navigation position in addition to scrolling. (#787)
-- Navigation: Added IsItemFocused(), added IsAnyItemFocused(). (#787)
-- Navigation: Added window flags: ImGuiWindowFlags_NoNav (== ImGuiWindowFlags_NoNavInputs | ImGuiWindowFlags_NoNavFocus).
-- Navigation: Style: Added ImGuiCol_NavHighlight, ImGuiCol_NavWindowingHighlight colors. (#787)
-- Navigation: TreeNode: Added ImGuiTreeNodeFlags_NavLeftJumpsBackHere flag to allow Nav Left direction to jump back to parent tree node from any of its child. (#1079)
-- Navigation: IO: Added io.ConfigFlags (input), io.NavActive (output), io.NavVisible (output). (#787)
-- Context: Removed the default global context and font atlas instances, which caused various problems to users of multiple contexts and DLL users. (#1565, #1599)
- YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. Existing apps will assert/crash without it.
-- Context: Added SetAllocatorFunctions() to rewire memory allocators (as a replacement to previous parameters to CreateContext()). Allocators are shared by all contexts and imgui helpers. (#1565, #586, #992, #1007, #1558)
-- Context: You may pass a ImFontAtlas to CreateContext() to specify a font atlas to share. Shared font atlas are not owned by the context and not destroyed along with it. (#1599)
-- Context: Added IMGUI_DISABLE_DEFAULT_ALLOCATORS to disable linking with malloc/free. (#1565, #586, #992, #1007, #1558)
-- IO: Added io.ConfigFlags for user application to store settings for imgui and for the backend:
- - ImGuiConfigFlags_NavEnableKeyboard: Enable keyboard navigation.
- - ImGuiConfigFlags_NavEnableGamepad: Enable gamepad navigation (provided ImGuiBackendFlags_HasGamepad is also set by backend).
- - ImGuiConfigFlags_NavEnableSetMousePos: Instruct navigation to move the mouse cursor. May be useful on TV/console systems where moving a virtual mouse is awkward.
- - ImGuiConfigFlags_NoMouseCursorChange: Instruct backend to not alter mouse cursor shape and visibility (by default the example backend use mouse cursor API of the platform when available)
- - ImGuiConfigFlags_NoMouse: Instruct imgui to clear mouse position/buttons in NewFrame(). This allows ignoring the mouse information passed by the backend.
- - ImGuiConfigFlags_IsSRGB, ImGuiConfigFlags_IsTouchScreen: Flags for general application use.
-- IO: Added io.BackendFlags for backend to store its capabilities (currently: _HasGamepad, _HasMouseCursors, _HasSetMousePos). This will be used more in the next version.
-- IO: Added ImGuiKey_Insert, ImGuiKey_Space keys. Setup in all example backends. (#1541)
-- IO: Added Horizontal Mouse Wheel support for horizontal scrolling. (#1463) [@tseeker]
-- IO: Added IsAnyMouseDown() helper which is helpful for backends to handle mouse capturing.
-- Window: Clicking on a window with the ImGuiWIndowFlags_NoMove flags takes an ActiveId so we can't hover something else when dragging afterwards. (#1381, #1337)
-- Window: IsWindowHovered(): Added ImGuiHoveredFlags_AnyWindow, ImGuiFocusedFlags_AnyWindow flags (See Breaking Changes). Added to demo. (#1382)
-- Window: Added SetNextWindowBgAlpha() helper. Particularly helpful since the legacy 5-parameters version of Begin() has been marked as obsolete in 1.53. (#1567)
-- Window: Fixed SetNextWindowContentSize() with 0.0f on Y axis (or SetNextWindowContentWidth()) overwriting the contents size. Got broken on Dec 10 (1.53). (#1363)
-- ArrowButton: Added ArrowButton() given a cardinal direction (e.g. ImGuiDir_Left).
-- InputText: Added alternative clipboard shortcuts: Shift+Delete (cut), CTRL+Insert (copy), Shift+Insert (paste). (#1541)
-- InputText: Fixed losing Cursor X position when clicking outside on an item that's submitted after the InputText(). It was only noticeable when restoring focus programmatically. (#1418, #1554)
-- InputText: Added ImGuiInputTextFlags_CharsScientific flag to also allow 'e'/'E' for input of values using scientific notation. Automatically used by InputFloat.
-- Style: Default style is now StyleColorsDark(), instead of the old StyleColorsClassic(). (#707)
-- Style: Enable window border by default. (#707)
-- Style: Exposed ImGuiStyleVar_WindowTitleAlign, ImGuiStyleVar_ScrollbarSize, ImGuiStyleVar_ScrollbarRounding, ImGuiStyleVar_GrabRounding + added an assert to reduce accidental breakage. (#1181)
-- Style: Added style.MouseCursorScale help when using the software mouse cursor facility. (#939).
-- Style: Close button nows display a cross before hovering. Fixed cross positioning being a little off. Uses button colors for highlight when hovering. (#707)
-- Popup: OpenPopup() Always reopen existing pop-ups. (Removed imgui_internal.h's OpenPopupEx() which was used for this.) (#1497, #1533).
-- Popup: BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick() all react on mouse release instead of mouse press. (~#439)
-- Popup: Better handling of user mistakenly calling OpenPopup() every frame (with reopen_existing option). The error will now be more visible and easier to understand. (#1497)
-- Popup: BeginPopup(): Exposed extra_flags parameter that are passed through to Begin(). (#1533)
-- Popup: BeginPopupModal: fixed the conditional test for SetNextWindowPos() which was polling the wrong window, which in practice made the test succeed all the time.
-- Tooltip: BeginTooltip() sets ImGuiWindowFlags_NoInputs flag.
-- Scrollbar: Fixed ScrollbarY enable test after ScrollbarX has been enabled being a little off (small regression from Nov 2017). (#1574)
-- Scrollbar: Fixed ScrollbarX enable test subtracting WindowPadding.x (this has been there since the addition of horizontal scroll bar!).
-- Columns: Clear offsets data when columns count changed. (#1525)
-- Columns: Fixed a memory leak of ImGuiColumnsSet's Columns vector. (#1529) [@unprompted]
-- Columns: Fixed resizing a window very small breaking some columns positioning (broken in 1.53).
-- Columns: The available column extent takes consideration of the right-most clipped pixel, so the right-most column may look a little wider but will contain the same amount of visible contents.
-- MenuBar: Fixed menu bar pushing a clipping rect outside of its allocated bound (usually unnoticeable).
-- TreeNode: nodes with the ImGuiTreeNodeFlags_Leaf flag correctly disable highlight when DragDrop is active. (#143, #581)
-- Drag and Drop: Increased payload type string to 32 characters instead of 8. (#143)
-- Drag and Drop: TreeNode as drop target displays rectangle over full frame. (#1597, #143)
-- DragFloat: Fix/workaround for backends which do not preserve a valid mouse position when dragged out of bounds. (#1559)
-- InputFloat: Allow inputing value using scientific notation e.g. "1e+10".
-- InputDouble: Added InputDouble() function. We use a format string instead of a decimal_precision parameter to also for "%e" and variants. (#1011)
-- Slider, Combo: Use ImGuiCol_FrameBgHovered color when hovered. (#1456) [@stfx]
-- Combo: BeginCombo(): Added ImGuiComboFlags_NoArrowButton to disable the arrow button and only display the wide value preview box.
-- Combo: BeginCombo(): Added ImGuiComboFlags_NoPreview to disable the preview and only display a square arrow button.
-- Combo: Arrow button isn't displayed over frame background so its blended color matches other buttons. Left side of the button isn't rounded.
-- PlotLines: plot a flat line if scale_min==scale_max. (#1621)
-- Fonts: Changed DisplayOffset.y to defaults to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer.
- If you were adding or subtracting (not assigning) to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. (#1619)
-- Fonts: Updated stb_truetype from 1.14 to stb_truetype 1.19. (w/ include fix from some platforms #1622)
-- Fonts: Added optional FreeType rasterizer in misc/freetype. Moved from imgui_club repo. (#618) [@Vuhdo, @mikesart, @ocornut]
-- Fonts: Moved extra_fonts/ to misc/fonts/.
-- ImFontAtlas: Fixed cfg.MergeMode not reusing existing glyphs if available (always overwrote).
-- ImFontAtlas: Handle stb_truetype stbtt_InitFont() and stbtt_PackBegin() possible failures more gracefully, GetTexDataAsRGBA32() won't crash during conversion. (#1527)
-- ImFontAtlas: Moved mouse cursor data out of ImGuiContext, fix drawing them with multiple contexts. Also remove the last remaining undesirable dependency on ImGui in imgui_draw.cpp. (#939)
-- ImFontAtlas: Added ImFontAtlasFlags_NoPowerOfTwoHeight flag to disable padding font height to nearest power of two. (#1613)
-- ImFontAtlas: Added ImFontAtlasFlags_NoMouseCursors flag to disable baking software mouse cursors, mostly to save texture memory on very low end hardware. (#1613)
-- ImDrawList: Fixed AddRect() with anti-aliasing disabled (lower-right corner pixel was often missing, rounding looks a little better.) (#1646)
-- ImDrawList: Added CloneOutput() helper to facilitate the cloning of ImDrawData or ImDrawList for multi-threaded rendering.
-- Misc: Functions passed to libc qsort are explicitly marked cdecl to support compiling with vectorcall as the default calling convention. (#1230, #1611) [@RandyGaul]
-- Misc: ImVec2: added [] operator. This is becoming desirable for some code working of either axes independently. Better adding it sooner than later.
-- Misc: NewFrame(): Added an assert to detect incorrect filling of the io.KeyMap[] array earlier. (#1555)
-- Misc: Added IM_OFFSETOF() helper in imgui.h (previously was in imgui_internal.h)
-- Misc: Added IM_NEW(), IM_DELETE() helpers in imgui.h (previously were in imgui_internal.h)
-- Misc: Added obsolete redirection function GetItemsLineHeightWithSpacing() (which redirects to GetFrameHeightWithSpacing()), as intended and stated in docs of 1.53.
-- Misc: Added misc/natvis/imgui.natvis for visual studio debugger users to easily visualize imgui internal types. Added to examples projects.
-- Misc: Added IMGUI_USER_CONFIG to define a custom configuration filename. (#255, #1573, #1144, #41)
-- Misc: Added IMGUI_STB_TRUETYPE_FILENAME and IMGUI_STB_RECT_PACK_FILENAME compile time directives to use another version of the stb_ files.
-- Misc: Updated stb_rect_pack from 0.10 to 0.11 (minor changes).
- (Those flags are not used by ImGui itself, they only exists to make it easy for the engine/backend to pass information to the application in a standard manner.)
-- Metrics: Added display of Columns state.
-- Demo: Improved Selectable() examples. (#1528)
-- Demo: Tweaked the Child demos, added a menu bar to the second child to test some navigation functions.
-- Demo: Console: Using ImGuiCol_Text to be more friendly to color changes.
-- Demo: Using IM_COL32() instead of ImColor() in ImDrawList centric contexts. Trying to phase out use of the ImColor helper whenever possible.
-- Examples: Files in examples/ now include their own changelog so it is easier to occasionally update your backends if needed.
-- Examples: Using Dark theme by default. (#707). Tweaked demo code.
-- Examples: Added support for horizontal mouse wheel for API that allows it. (#1463) [@tseeker]
-- Examples: All examples now setup the io.BackendFlags to signify they can honor mouse cursors, gamepad, etc.
-- Examples: DirectX10: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) in every other backends. (#1733)
-- Examples: DirectX12: Added DirectX 12 example. (#301) [@jdm3]
-- Examples: OpenGL3+GLFW,SDL: Changed GLSL shader version from 330 to 150. (#1466, #1504)
-- Examples: OpenGL3+GLFW,SDL: Added a way to override the GLSL version string in the Init function. (#1466, #1504).
-- Examples: OpenGL3+GLFW,SDL: Creating VAO in the render function so it can be more easily used by multiple shared OpenGL contexts. (#1217)
-- Examples: OpenGL3+GLFW: Using 3.2 context instead of 3.3. (#1466)
-- Examples: OpenGL: Setting up glPixelStorei() explicitly before uploading texture.
-- Examples: OpenGL: Calls to glPolygonMode() are casting parameters as GLEnum to not fail with more strict backends. (#1628) [@ilia-glushchenko]
-- Examples: Win32 (DirectX9,10,11,12): Added support for mouse cursor shapes. (#1495)
-- Examples: Win32 (DirectX9,10,11,12: Support for windows using the CS_DBLCLKS class flag by handling the double-click messages (WM_LBUTTONDBLCLK etc.). (#1538, #754) [@ndandoulakis]
-- Examples: Win32 (DirectX9,10,11,12): Made the Win32 proc handlers not assert if there is no active context yet, to be more flexible with creation order. (#1565)
-- Examples: GLFW: Added support for mouse cursor shapes (the diagonal resize cursors are unfortunately not supported by GLFW at the moment. (#1495)
-- Examples: GLFW: Don't attempt to change the mouse cursor input mode if it is set to GLFW_CURSOR_DISABLED by the application. (#1202) [@PhilCK]
-- Examples: SDL: Added support for mouse cursor shapes. (#1626) [@olls]
-- Examples: SDL: Using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging (SDL 2.0.4+ only, otherwise using SDL_WINDOW_INPUT_FOCUS instead of previously SDL_WINDOW_MOUSE_FOCUS). (#1559)
-- Examples: SDL: Enabled vsync by default so people don't come at us when the examples are running at 2000 FPS and burning a CPU core.
-- Examples: SDL: Using SDL_GetPerformanceCounter() / SDL_GetPerformanceFrequency() to handle frame-rate over 1000 FPS properly. (#996)
-- Examples: SDL: Using scan-code exclusively instead of a confusing mixture of scan-codes and key-codes.
-- Examples: SDL: Visual Studio: Added .vcxproj file. Using %SDL2_DIR% in the default .vcxproj and build files instead of %SDL_DIR%, the earlier being more standard.
-- Examples: Vulkan: Visual Studio: Added .vcxproj file.
-- Examples: Apple: Fixed filenames in OSX xcode project. Various other Mac friendly fixes. [@gerryhernandez etc.]
-- Examples: Visual Studio: Disabled extraneous function-level check in Release build.
-- Various fixes, tweaks, internal refactoring, optimizations, comments.

------------------------------------------------------------------------
- VERSION 1.53 (Released 2017-12-25)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.53
-
-Breaking Changes:
-
-- Renamed the emblematic `ShowTestWindow()` function to `ShowDemoWindow()`. Kept redirection function (will obsolete).
-- Renamed `GetItemsLineHeightWithSpacing()` to `GetFrameHeightWithSpacing()` for consistency. Kept redirection function (will obsolete).
-- Renamed `ImGuiTreeNodeFlags_AllowOverlapMode` flag to `ImGuiTreeNodeFlags_AllowItemOverlap`. Kept redirection enum (will obsolete).
-- Obsoleted `IsRootWindowFocused()` in favor of using `IsWindowFocused(ImGuiFocusedFlags_RootWindow)`. Kept redirection function (will obsolete). (#1382)
-- Obsoleted `IsRootWindowOrAnyChildFocused()` in favor of using `IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)`. Kept redirection function (will obsolete). (#1382)
-- Obsoleted `IsRootWindowOrAnyChildHovered()` in favor of using `IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)`. Kept redirection function (will obsolete). (#1382)
-- Obsoleted `SetNextWindowContentWidth() in favor of using `SetNextWindowContentSize()`. Kept redirection function (will obsolete).
-- Renamed `ImGuiTextBuffer::append()` helper to `appendf()`, and `appendv()` to `appendfv()` for consistency. If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
-- ImDrawList: Removed 'bool anti_aliased = true' final parameter of `ImDrawList::AddPolyline()` and `ImDrawList::AddConvexPolyFilled()`. Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
-- Style, ImDrawList: Renamed `style.AntiAliasedShapes` to `style.AntiAliasedFill` for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags.
-- Style, Begin: Removed `ImGuiWindowFlags_ShowBorders` window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. `style.FrameBorderSize`, `style.WindowBorderSize`, `style.PopupBorderSize`).
- Use `ImGui::ShowStyleEditor()` to look them up.
- Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time.
- It is recommended that you use the `StyleColorsClassic()`, `StyleColorsDark()`, `StyleColorsLight()` functions. Also see `ShowStyleSelector()`.
-- Style: Removed `ImGuiCol_ComboBg` in favor of combo boxes using `ImGuiCol_PopupBg` for consistency. Combo are normal pop-ups.
-- Style: Renamed `ImGuiCol_ChildWindowBg` to `ImGuiCol_ChildBg`.
-- Style: Renamed `style.ChildWindowRounding` to `style.ChildRounding`, `ImGuiStyleVar_ChildWindowRounding` to `ImGuiStyleVar_ChildRounding`.
-- Removed obsolete redirection functions: SetScrollPosHere() - marked obsolete in v1.42, July 2015.
-- Removed obsolete redirection functions: GetWindowFont(), GetWindowFontSize() - marked obsolete in v1.48, March 2016.
-
-Other Changes:
-
-- Added `io.OptCursorBlink` option to allow disabling cursor blinking. (#1427) [renamed to io.ConfigCursorBlink in 1.63]
-- Added `GetOverlayDrawList()` helper to quickly get access to a ImDrawList that will be rendered in front of every windows.
-- Added `GetFrameHeight()` helper which returns `(FontSize + style.FramePadding.y * 2)`.
-- Drag and Drop: Added Beta API to easily use drag and drop patterns between imgui widgets.
- - Setup a source on a widget with `BeginDragDropSource()`, `SetDragDropPayload()`, `EndDragDropSource()` functions.
- - Receive data with `BeginDragDropTarget()`, `AcceptDragDropPayload()`, `EndDragDropTarget()`.
- - See ImGuiDragDropFlags for various options.
- - The ColorEdit4() and ColorButton() widgets now support Drag and Drop.
- - The API is tagged as Beta as it still may be subject to small changes.
-- Drag and Drop: When drag and drop is active, tree nodes and collapsing header can be opened by hovering on them for 0.7 seconds.
-- Renamed io.OSXBehaviors to io.OptMacOSXBehaviors. Should not affect users as the compile-time default is usually enough. (#473, #650)
-- Style: Added StyleColorsDark() style. (#707) [@dougbinks]
-- Style: Added StyleColorsLight() style. Best used with frame borders + thicker font than the default font. (#707)
-- Style: Added style.PopupRounding setting. (#1112)
-- Style: Added style.FrameBorderSize, style.WindowBorderSize, style.PopupBorderSize. Removed ImGuiWindowFlags_ShowBorders window flag!
- Borders are now fully set up in the ImGuiStyle structure. Use ImGui::ShowStyleEditor() to look them up. (#707, fix #819, #1031)
-- Style: Various small changes to the classic style (most noticeably, buttons are now using blue shades). (#707)
-- Style: Renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
-- Style: Renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
-- Style: Removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. (#707)
-- Style: Made the ScaleAllSizes() helper rounds down every values so they are aligned on integers.
-- Focus: Added SetItemDefaultFocus(), which in the current (master) branch behave the same as doing `if (IsWindowAppearing()) SetScrollHere()`.
- In the navigation branch this will also set the default focus. Prefer using this when creating combo boxes with `BeginCombo()` so your code will be forward-compatible with gamepad/keyboard navigation features. (#787)
-- Combo: Pop-up grows horizontally to accommodate for contents that is larger then the parent combo button.
-- Combo: Added BeginCombo()/EndCombo() API which allows use to submit content of any form and manage your selection state without relying on indices.
-- Combo: Added ImGuiComboFlags_PopupAlignLeft flag to BeginCombo() to prioritize keeping the pop-up on the left side (for small-button-looking combos).
-- Combo: Added ImGuiComboFlags_HeightSmall, ImGuiComboFlags_HeightLarge, ImGuiComboFlags_HeightLargest to easily provide desired pop-up height.
-- Combo: You can use SetNextWindowSizeConstraints() before BeginCombo() to specify specific pop-up width/height constraints.
-- Combo: Offset popup position by border size so that a double border isn't so visible. (#707)
-- Combo: Recycling windows by using a stack number instead of a unique id, wasting less memory (like menus do).
-- InputText: Added ImGuiInputTextFlags_NoUndoRedo flag. (#1506, #1508) [@ibachar]
-- Window: Fixed auto-resize allocating too much space for scrollbar when SizeContents is bigger than maximum window size (fixes c0547d3). (#1417)
-- Window: Child windows with MenuBar use regular WindowPadding.y so layout look consistent as child or as a regular window.
-- Window: Begin(): Fixed appending into a child window with a second Begin() from a different window stack querying the wrong window for the window->Collapsed test.
-- Window: Calling IsItemActive(), IsItemHovered() etc. after a call to Begin() provides item data for the title bar, so you can easily test if the title bar is being hovered, etc. (#823)
-- Window: Made it possible to use SetNextWindowPos() on a child window.
-- Window: Fixed a one frame glitch. When an appearing window claimed the focus themselves, the title bar wouldn't use the focused color for one frame.
-- Window: Added ImGuiWindowFlags_ResizeFromAnySide flag to resize from any borders or from the lower-left corner of a window. This requires your backend to honor GetMouseCursor() requests for full usability. (#822)
-- Window: Sizing fixes when using SetNextWindowSize() on individual axises.
-- Window: Hide new window for one frame until they calculate their size. Also fixes SetNextWindowPos() given a non-zero pivot. (#1694)
-- Window: Made mouse wheel scrolling accommodate better to windows that are smaller than the scroll step.
-- Window: SetNextWindowContentSize() adjust for the size of decorations (title bar/menu bar), but _not_ for borders are we consistently make borders not affect layout.
- If you need a non-child window of an exact size with border enabled but zero window padding, you'll need to accommodate for the border size yourself.
-- Window: Using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. (#1380, #1502)
-- Window: Active Modal window always set the WantCaptureKeyboard flag. (#744)
-- Window: Moving window doesn't use accumulating MouseDelta so straying out of imgui boundaries keeps moved imgui window at the same cursor-relative position.
-- IsWindowFocused(): Added ImGuiFocusedFlags_ChildWindows flag to include child windows in the focused test. (#1382).
-- IsWindowFocused(): Added ImGuiFocusedFlags_RootWindow flag to start focused test from the root (top-most) window. Obsolete IsRootWindowFocused(). (#1382)
-- IsWindowHovered(): Added ImGuiHoveredFlags_ChildWindows flag to include child windows in the hovered test. (#1382).
-- IsWindowHovered(): Added ImGuiHoveredFlags_RootWindow flag to start hovered test from the root (top-most) window. The combination of both flags obsoletes IsRootWindowOrAnyChildHovered(). (#1382)
-- IsWindowHovered(): Fixed return value when an item is active to use the same logic as IsItemHovered(). (#1382, #1404)
-- IsWindowHovered(): Always return true when current window is being moved. (#1382)
-- Scrollbar: Fixed issues with vertical scrollbar flickering/appearing, typically when manually resizing and using a pattern of filling available height (e.g. full sized BeginChild).
-- Scrollbar: Minor graphical fix for when scrollbar don't have enough visible space to display the full grab.
-- Scrolling: Fixed padding and scrolling asymmetry where lower/right sides of a window wouldn't use WindowPadding properly + causing minor scrolling glitches.
-- Tree: TreePush with zero arguments was ambiguous. Resolved by making it call TreePush(const void*). [@JasonWilkins]
-- Tree: Renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. (#600, #1330)
-- MenuBar: Fixed minor rendering issues on the right size when resizing a window very small and using rounded window corners.
-- MenuBar: better software clipping to handle small windows, in particular child window don't have minimum constraints so we need to render clipped menus better.
-- BeginMenu(): Tweaked the Arrow/Triangle displayed on child menu items.
-- Columns: Clipping columns borders on Y axis on CPU because some Linux GPU drivers appears to be unhappy with triangle spanning large regions. (#125)
-- Columns: Added ImGuiColumnsFlags_GrowParentContentsSize to internal API to restore old content sizes behavior (may be obsolete). (#1444, #125)
-- Columns: Columns width is no longer lost when dragging a column to the right side of the window, until releasing the mouse button you have a chance to save them. (#1499, #125). [@ggtucker]
-- Columns: Fixed dragging when using a same of columns multiple times in the frame. (#125)
-- Indent(), Unindent(): Allow passing negative values.
-- ColorEdit4(): Made IsItemActive() return true when picker pop-up is active. (#1489)
-- ColorEdit4(): Tweaked tooltip so that the color button aligns more correctly with text.
-- ColorEdit4(): Support drag and drop. Color buttons can be used as drag sources, and ColorEdit widgets as drag targets. (#143)
-- ColorPicker4(): Fixed continuously returning true when holding mouse button on the sat/value/alpha locations. We only return true on value change. (#1489)
-- NewFrame(): using literal strings in the most-frequently firing IM_ASSERT expressions to increase the odd of programmers seeing them (especially those who don't use a debugger).
-- NewFrame() now asserts if neither Render or EndFrame have been called. Exposed EndFrame(). Made it legal to call EndFrame() more than one. (#1423)
-- ImGuiStorage: Added BuildSortByKey() helper to rebuild storage from scratch.
-- ImFont: Added GetDebugName() helper.
-- ImFontAtlas: Added missing Thai punctuation in the GetGlyphRangesThai() ranges. (#1396) [@nProtect]
-- ImDrawList: Removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Anti-aliasing is controlled via the regular style.AntiAliased flags.
-- ImDrawList: Added ImDrawList::AddImageRounded() helper. (#845) [@thedmd]
-- ImDrawList: Refactored to make ImDrawList independent of ImGui. Removed static variable in PathArcToFast() which caused linking issues to some.
-- ImDrawList: Exposed ImDrawCornerFlags, replaced occurrences of ~0 with an explicit ImDrawCornerFlags_All. NB: Inversed BotLeft (prev 1<<3, now 1<<2) and BotRight (prev 1<<2, now 1<<3).
-- ImVector: Added ImVector::push_front() helper.
-- ImVector: Added ImVector::contains() helper.
-- ImVector: insert() uses grow_capacity() instead of using grow policy inconsistent with push_back().
-- Internals: Remove requirement to define IMGUI_DEFINE_PLACEMENT_NEW to use the IM_PLACEMENT_NEW macro. (#1103)
-- Internals: ButtonBehavior: Fixed ImGuiButtonFlags_NoHoldingActiveID flag from incorrectly setting the ActiveIdClickOffset field.
- This had no known effect within imgui code but could have affected custom drag and drop patterns. And it is more correct this way! (#1418)
-- Internals: ButtonBehavior: Fixed ImGuiButtonFlags_AllowOverlapMode to avoid temporarily activating widgets on click before they have been correctly double-hovered. (#319, #600)
-- Internals: Added SplitterBehavior() helper. (#319)
-- Internals: Added IM_NEW(), IM_DELETE() helpers. (#484, #504, #1517)
-- Internals: Basic refactor of the settings API which now allows external elements to be loaded/saved.
-- Demo: Added ShowFontSelector() showing loaded fonts.
-- Demo: Added ShowStyleSelector() to select among default styles. (#707)
-- Demo: Renamed the emblematic ShowTestWindow() function to ShowDemoWindow().
-- Demo: Style Editor: Added a "Simplified settings" sections with check-boxes for border size and frame rounding. (#707, #1019)
-- Demo: Style Editor: Added combo box to select stock styles and select current font when multiple are loaded. (#707)
-- Demo: Style Editor: Using local storage so Save/Revert button makes more sense without code passing its storage. Added horizontal scroll bar. Fixed Save/Revert button to be always accessible. (#1211)
-- Demo: Console: Fixed context menu issue. (#1404)
-- Demo: Console: Fixed incorrect positioning which was hidden by a minor scroll issue (this would affect people who copied the Console code as is).
-- Demo: Constrained Resize: Added more test cases. (#1417)
-- Demo: Custom Rendering: Fixed clipping rectangle extruding out of parent window.
-- Demo: Layout: Removed unnecessary and misleading BeginChild/EndChild calls.
-- Demo: The "Color Picker with Palette" demo supports drag and drop. (#143)
-- Demo: Display better mouse cursor info for debugging backends.
-- Demo: Stopped using rand() function in demo code.
-- Examples: Added a handful of extra comments (about fonts, third-party libraries used in the examples, etc.).
-- Examples: DirectX9: Handle loss of D3D9 device (D3DERR_DEVICELOST). (#1464)
-- Examples: Added null_example/ which is helpful for quick testing on multiple compilers/settings without relying on graphics library.
-- Fix for using alloca() in "Clang with Microsoft Codechain" mode.
-- Various fixes, optimizations, comments.

------------------------------------------------------------------------
- VERSION 1.52 (2017-10-27)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.52
-
-Breaking Changes:
-
-- IO: `io.MousePos` needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing, instead of ImVec2(-1,-1) as previously) This is needed so we can clear `io.MouseDelta` field when the mouse is made available again.
-- Renamed `AlignFirstTextHeightToWidgets()` to `AlignTextToFramePadding()`. Kept inline redirection function (will obsolete).
-- Obsoleted the legacy 5 parameters version of Begin(). Please avoid using it. If you need a transparent window background, uses `PushStyleColor()`. The old size parameter there was also misleading and equivalent to calling `SetNextWindowSize(size, ImGuiCond_FirstTimeEver)`. Kept inline redirection function (will obsolete).
-- Obsoleted `IsItemHoveredRect()`, `IsMouseHoveringWindow()` in favor of using the newly introduced flags of `IsItemHovered()` and `IsWindowHovered()`. Kept inline redirection function (will obsolete). (#1382)
-- Obsoleted 'SetNextWindowPosCenter()' in favor of using 1SetNextWindowPos()` with a pivot value which allows to do the same and more. Keep inline redirection function.
-- Removed `IsItemRectHovered()`, `IsWindowRectHovered()` recently introduced in 1.51 which were merely the more consistent/correct names for the above functions which are now obsolete anyway. (#1382)
-- Changed `IsWindowHovered()` default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. (#1382)
-- Renamed imconfig.h's `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS` to `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS` for consistency.
-- Renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete).
-
-Other Changes:
-
-- ProgressBar: fixed rendering when straddling rounded area. (#1296)
-- SliderFloat, DragFloat: Using scientific notation e.g. "%.1e" in the displayed format string doesn't mistakenly trigger rounding of the value. [@MomentsInGraphics]
-- Combo, InputFloat, InputInt: Made the small button on the right side align properly with the equivalent colored button of ColorEdit4().
-- IO: Tweaked logic for `io.WantCaptureMouse` so it now outputs false when e.g. hovering over void while an InputText() is active. (#621) [@pdoane]
-- IO: Fixed `io.WantTextInput` from mistakenly outputting true when an activated Drag or Slider was previously turned into an InputText(). (#1317)
-- Misc: Added flags to `IsItemHovered()`, `IsWindowHovered()` to access advanced hovering-test behavior. Generally useful for pop-ups and drag and drop behaviors: (relates to ~#439, #1013, #143, #925)
- - `ImGuiHoveredFlags_AllowWhenBlockedByPopup`
- - `ImGuiHoveredFlags_AllowWhenBlockedByActiveItem`
- - `ImGuiHoveredFlags_AllowWhenOverlapped`
- - `ImGuiHoveredFlags_RectOnly`
-- Input: Added `IsMousePosValid()` helper.
-- Input: Added `GetKeyPressedAmount()` to easily measure press count when the repeat rate is faster than the frame rate.
-- Input/Focus: Disabled TAB and Shift+TAB when CTRL key is held.
-- CheckBox: Now rendering a tick mark instead of a full square.
-- ColorEdit4: Added "Copy as..." option in context menu. (#346)
-- ColorPicker: Improved ColorPicker hue wheel color interpolation. (#1313) [@thevaber]
-- ColorButton: Reduced bordering artifact that would be particularly visible with an opaque Col_FrameBg and FrameRounding enabled.
-- ColorButton: Fixed rendering color button with a checkerboard if the transparency comes from the global style.Alpha and not from the actual source color.
-- TreeNode: Added `ImGuiTreeNodeFlags_FramePadding` flag to conveniently create a tree node with full padding at the beginning of a line, without having to call `AlignTextToFramePadding()`.
-- Trees: Fixed calling `SetNextTreeNodeOpen()` on a collapsed window leaking to the first tree node item of the next frame.
-- Layout: Horizontal layout is automatically enforced in a menu bar, so you can use non-MenuItem elements without calling SameLine().
-- Separator: Output a vertical separator when used inside a menu bar (or in general when horizontal layout is active, but that isn't exposed yet!).
-- Window: Added `IsWindowAppearing()` helper (helpful e.g. as a condition before initializing some of your own things.).
-- Window: Added pivot parameter to `SetNextWindowPos()`, making it possible to center or right align a window. Obsoleted `SetNextWindowPosCenter()`.
-- Window: Fixed title bar color of top-most window under a modal window.
-- Window: Fixed not being able to move a window by clicking on one of its child window. (#1337, #635)
-- Window: Fixed `Begin()` auto-fit calculation code that predict the presence of a scrollbar so it works better when window size constraints are used.
-- Window: Fixed calling `Begin()` more than once per frame setting `window_just_activated_by_user` which in turn would set enable the Appearing condition for that frame.
-- Window: The implicit "Debug" window now uses a "Debug##Default" identifier instead of "Debug" to allow user creating a window called "Debug" without losing their custom flags.
-- Window: Made the `ImGuiWindowFlags_NoMove` flag properly inherited from parent to child. In a setup with ParentWindow (no flag) -> Child (NoMove) -> SubChild (no flag), the user won't be able to move the parent window by clicking on SubChild. (#1381)
-- Popups: Pop-ups can be closed with a right-click anywhere, without altering focus under the pop-up. (~#439)
-- Popups: `BeginPopupContextItem()`, `BeginPopupContextWindow()` are now setup to allow reopening a context menu by right-clicking again. (~#439)
-- Popups: `BeginPopupContextItem()` now supports a NULL string identifier and uses the last item ID if available.
-- Popups: Added `OpenPopupOnItemClick()` helper which mimic `BeginPopupContextItem()` but doesn't do the BeginPopup().
-- MenuItem: Only activating on mouse release. [@Urmeli0815] (was already fixed in nav branch).
-- MenuItem: Made tick mark thicker (thick mark?).
-- MenuItem: Tweaks to be usable inside a menu bar (nb: it looks like a regular menu and thus is misleading, prefer using Button() and regular widgets in menu bar if you need to). (#1387)
-- ImDrawList: Fixed a rare draw call merging bug which could lead to undisplayed triangles. (#1172, #1368)
-- ImDrawList: Fixed a rare bug in `ChannelsMerge()` when all contents has been clipped, leading to an extraneous draw call being created. (#1172, #1368)
-- ImFont: Added `AddGlyph()` building helper for use by custom atlas builders.
-- ImFontAtlas: Added support for CustomRect API to submit custom rectangles to be packed into the atlas. You can map them as font glyphs, or use them for custom purposes.
- After the atlas is built you can query the position of your rectangles in the texture and then copy your data there. You can use this features to create e.g. full color font-mapped icons.
-- ImFontAtlas: Fixed fall-back handling when merging fonts, if a glyph was missing from the second font input it could have used a glyph from the first one. (#1349) [@inolen]
-- ImFontAtlas: Fixed memory leak on build failure case when stbtt_InitFont failed (generally due to incorrect or supported font type). (#1391) (@Moka42)
-- ImFontConfig: Added `RasterizerMultiply` option to alter the brightness of individual fonts at rasterization time, which may help increasing readability for some.
-- ImFontConfig: Added `RasterizerFlags` to pass options to custom rasterizer (e.g. the [imgui_freetype](https://github.com/ocornut/imgui_club/tree/master/imgui_freetype) rasterizer in imgui_club has such options).
-- ImVector: added resize() variant with initialization value.
-- Misc: Changed the internal name formatting of child windows identifier to use slashes (instead of dots) as separator, more readable.
-- Misc: Fixed compilation with `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` defined.
-- Misc: Marked all format+va_list functions with format attribute so GCC/Clang can warn about misuses.
-- Misc: Fixed compilation on NetBSD due to missing alloca.h (#1319) [@RyuKojiro]
-- Misc: Improved warnings compilation for newer versions of Clang. (#1324) (@waywardmonkeys)
-- Misc: Added `io.WantMoveMouse flags` (from Nav branch) and honored in Examples applications. Currently unused but trying to spread Examples applications code that supports it.
-- Misc: Added `IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS` support in imconfig.h to allow user reimplementing the `ImFormatString()` functions e.g. to use stb_printf(). (#1038)
-- Misc: [Windows] Fixed default Win32 `SetClipboardText()` handler leaving the Win32 clipboard handler unclosed on failure. [@pdoane]
-- Style: Added `ImGuiStyle::ScaleAllSizes(float)` helper to make it easier to have application transition e.g. from low to high DPI with a matching style.
-- Metrics: Draw window bounding boxes when hovering Pos/Size; List all draw layers; Trimming empty commands like Render() does.
-- Examples: OpenGL3: Save and restore sampler state. (#1145) [@nlguillemot]
-- Examples: OpenGL2, OpenGL3: Save and restore polygon mode. (#1307) [@JJscott]
-- Examples: DirectX11: Allow creating device with feature level 10 since we don't really need much for that example. (#1333)
-- Examples: DirectX9/10/12: Using the Win32 SetCapture/ReleaseCapture API to read mouse coordinates when they are out of bounds. (#1375) [@Gargaj, @ocornut]
-- Tools: Fixed binary_to_compressed_c tool to return 0 when successful. (#1350) [@benvanik]
-- Internals: Exposed more helpers and unfinished features in imgui_internal.h. (use at your own risk!).
-- Internals: A bunch of internal refactoring, hopefully haven't broken anything! Merged a bunch of internal changes from the upcoming Navigation branch.
-- Various tweaks, fixes and documentation changes.
-
-Beta Navigation Branch:
-(Lots of work has been done toward merging the Beta Gamepad/Keyboard Navigation branch (#787) in master.)
-(Please note that this branch is always kept up to date with master. If you are using the navigation branch, some of the changes include:)
-- Nav: Added `#define IMGUI_HAS_NAV` in imgui.h to ease sharing code between both branches. (#787)
-- Nav: MainMenuBar now releases focus when user gets out of the menu layer. (#787)
-- Nav: When applying focus to a window with only menus, the menu layer is automatically activated. (#787)
-- Nav: Added `ImGuiNavInput_KeyMenu` (~Alt key) aside from ImGuiNavInput_PadMenu input as it is one differentiator of pad vs keyboard that was detrimental to the keyboard experience. Although isn't officially supported, it makes the current experience better. (#787)
-- Nav: Move requests now wrap vertically inside Menus and Pop-ups. (#787)
-- Nav: Allow to collapse tree nodes with NavLeft and open them with NavRight. (#787, #1079).
-- Nav: It's now possible to navigate sibling of a menu-bar while navigating inside one of their child. If a Left<>Right navigation request fails to find a match we forward the request to the root menu. (#787, #126)
-- Nav: Fixed `SetItemDefaultFocus` from stealing default focus when we are initializing default focus for a menu bar layer. (#787)
-- Nav: Support for fall-back horizontal scrolling with PadLeft/PadRight (nb: fall-back scrolling is only used to navigate windows that have no interactive items). (#787)
-- Nav: Fixed tool-tip from being selectable in the window selection list. (#787)
-- Nav: `CollapsingHeader(bool*)` variant: fixed for `IsItemHovered()` not working properly in the nav branch. (#600, #787)
-- Nav: InputText: Fixed using Up/Down history callback feature when Nav is enabled. (#787)
-- Nav: InputTextMultiline: Fixed navigation/selection. Disabled selecting all when activating a multi-line text editor. (#787)
-- Nav: More consistently drawing a (thin) navigation rectangle hover filled frames such as tree nodes, collapsing header, menus. (#787)
-- Nav: Various internal refactoring.

- VERSION 1.51 (2017-08-24)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.51
-
-Breaking Changes:
-
-Work on dear imgui has been gradually resuming. It means that fixes and new features should be tackled at a faster rate than last year. However, in order to move forward with the library and get rid of some cruft, I have taken the liberty to be a little bit more aggressive than usual with API breaking changes. Read the details below and search for those names in your code! In the grand scheme of things, those changes are small and should not affect everyone, but this is technically our most aggressive release so far in term of API breakage. If you want to be extra forward-facing, you can enable `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h to disable the obsolete names/redirection.
-
-- Renamed `IsItemHoveredRect()` to `IsItemRectHovered()`. Kept inline redirection function (will obsolete).
-- Renamed `IsMouseHoveringWindow()` to `IsWindowRectHovered()` for consistency. Kept inline redirection function (will obsolete).
-- Renamed `IsMouseHoveringAnyWindow()` to `IsAnyWindowHovered()` for consistency. Kept inline redirection function (will obsolete).
-- Renamed `ImGuiCol_Columns***` enums to `ImGuiCol_Separator***`. Kept redirection enums (will obsolete).
-- Renamed `ImGuiSetCond***` types and enums to `ImGuiCond***`. Kept redirection enums (will obsolete).
-- Renamed `GetStyleColName()` to `GetStyleColorName()` for consistency. Unlikely to be used by end-user!
-- Added `PushStyleColor(ImGuiCol idx, ImU32 col)` overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicitly to fix.
-- Marked the weird `IMGUI_ONCE_UPON_A_FRAME` helper macro as obsolete. Prefer using the more explicit `ImGuiOnceUponAFrame`.
-- Changed `ColorEdit4(const char* label, float col[4], bool show_alpha = true)` signature to `ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)`, where flags 0x01 is a safe no-op (hello dodgy backward compatibility!). The new `ColorEdit4`/`ColorPicker4` functions have lots of available flags! Check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
-- Changed signature of `ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)` to `ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))`. This function was rarely used and was very dodgy (no explicit ID!).
-- Changed `BeginPopupContextWindow(bool also_over_items=true, const char* str_id=NULL, int mouse_button=1)` signature to `(const char* str_id=NULL, int mouse_button=1, bool also_over_items=true)`. This is perhaps the most aggressive change in this update, but note that the majority of users relied on default parameters completely, so this will affect only a fraction of users of this already rarely used function.
-- Removed `IsPosHoveringAnyWindow()`, which was partly broken and misleading. In the vast majority of cases, people using that function wanted to use `io.WantCaptureMouse` flag. Replaced with IM_ASSERT + comment redirecting user to `io.WantCaptureMouse`. (#1237)
-- Removed the old `ValueColor()` helpers, they are equivalent to calling `Text(label)` + `SameLine()` + `ColorButton()`.
-- Removed `ColorEditMode()` and `ImGuiColorEditMode` type in favor of `ImGuiColorEditFlags` and parameters to the various Color*() functions. The `SetColorEditOptions()` function allows to initialize default but the user can still change them with right-click context menu. Commenting out your old call to `ColorEditMode()` may just be fine!
-
-Other Changes:
-
-- Added flags to `ColorEdit3()`, `ColorEdit4()`. The color edit widget now has a context-menu and access to the color picker. (#346)
-- Added flags to `ColorButton()`. (#346)
-- Added `ColorPicker3()`, `ColorPicker4()`. The API along with those of the updated `ColorEdit4()` was designed so you may use them in various situation and hopefully compose your own picker if required. There are a bunch of available flags, check the Demo window and comment for `ImGuiColorEditFlags_`. Some of the options it supports are: two color picker types (hue bar + sat/val rectangle, hue wheel + rotating sat/val triangle), display as u8 or float, lifting 0.0..1.0 constraints (currently rgba only), context menus, alpha bar, background checkerboard options, preview tooltip, basic revert. For simple use, calling the existing `ColorEdit4()` function as you did before will be enough, as you can now open the color picker from there. (#346) [@r-lyeh, @nem0, @thennequin, @dariomanesku and @ocornut]
-- Added `SetColorEditOptions()` to set default color options (e.g. if you want HSV over RGBA, float over u8, select a default picker mode etc. at startup time without a user intervention. Note that the user can still change options with the context menu unless disabled with `ImGuiColorFlags_NoOptions` or explicitly enforcing a display type/picker mode etc.).
-- Added user-facing `IsPopupOpen()` function. (#891) [@mkeeter]
-- Added `GetColorU32(u32)` variant that perform the style alpha multiply without a floating-point round trip, and helps makes code more consistent when using ImDrawList APIs.
-- Added `PushStyleColor(ImGuiCol idx, ImU32 col)` overload.
-- Added `GetStyleColorVec4(ImGuiCol idx)` which is equivalent to accessing `ImGui::GetStyle().Colors[idx]` (aka return the raw style color without alpha alteration).
-- ImFontAtlas: Added `GlyphRangesBuilder` helper class, which makes it easier to build custom glyph ranges from your app/game localization data, or add into existing glyph ranges.
-- ImFontAtlas: Added `TexGlyphPadding` option. (#1282) [@jadwallis]
-- ImFontAtlas: Made it possible to override size of AddFontDefault() (even if it isn't really recommended!).
-- ImDrawList: Added `GetClipRectMin()`, `GetClipRectMax()` helpers.
-- Fixed Ini saving crash if the ImGuiWindowFlags_NoSavedSettings gets removed from a window after its creation (unlikely!). (#1000)
-- Fixed `PushID()`/`PopID()` from marking parent window as Accessed (which needlessly woke up the root "Debug" window when used outside of a regular window). (#747)
-- Fixed an assert when calling `CloseCurrentPopup()` twice in a row. [@nem0]
-- Window size can be loaded from .ini data even if ImGuiWindowFlags_NoResize flag is set. (#1048, #1056)
-- Columns: Added `SetColumnWidth()`. (#913) [@ggtucker]
-- Columns: Dragging a column preserve its width by default. (#913) [@ggtucker]
-- Columns: Fixed first column appearing wider than others. (#1266)
-- Columns: Fixed allocating space on the right-most side with the assumption of a vertical scrollbar. The space is only allocated when needed. (#125, #913, #893, #1138)
-- Columns: Fixed the right-most column from registering its content width to the parent window, which led to various issues when using auto-resizing window or e.g. horizontal scrolling. (#519, #125, #913)
-- Columns: Refactored some of the columns code internally toward a better API (not yet exposed) + minor optimizations. (#913) [@ggtucker, @ocornut]
-- Popups: Most pop-ups windows can be moved by the user after appearing (if they don't have explicit positions provided by caller, or e.g. sub-menu pop-up). The previous restriction was totally arbitrary. (#1252)
-- Tooltip: `SetTooltip()` is expanded immediately into a window, honoring current font / styling setting. Add internal mechanism to override tooltips. (#862)
-- PlotHistogram: bars are drawn based on zero-line, so negative values are going under. (#828)
-- Scrolling: Fixed return values of `GetScrollMaxX()`, `GetScrollMaxY()` when both scrollbars were enabled. Tweak demo to display more data. (#1271) [@degracode]
-- Scrolling: Fixes for Vertical Scrollbar not automatically getting enabled if enabled Horizontal Scrollbar straddle the vertical limit. (#1271, #246)
-- Scrolling: `SetScrollHere()`, `SetScrollFromPosY()`: Fixed Y scroll aiming when Horizontal Scrollbar is enabled. (#665).
-- [Windows] Clipboard: Fixed not closing Win32 clipboard on early open failure path. (#1264)
-- Removed an unnecessary dependency on int64_t which failed on some older compilers.
-- Demo: Rearranged everything under Widgets in a more consistent way.
-- Demo: Columns: Added Horizontal Scrolling demo. Tweaked another Columns demo. (#519, #125, #913)
-- Examples: OpenGL: Various makefiles for MINGW, Linux. (#1209, #1229, #1209) [@fr500, @acda]
-- Examples: Enabled vsync by default in example applications, so it doesn't confuse people that the sample run at 2000+ fps and waste an entire CPU. (#1213, #1151).
-- Various other small fixes, tweaks, comments, optimizations.

- VERSION 1.50 (2017-06-02)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.50
-
-Breaking Changes:
-
-- Added a void* user_data parameter to Clipboard function handlers. (#875)
-- SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal.
-- Renamed ImDrawList::PathFill() - rarely used directly - to ImDrawList::PathFillConvex() for clarity and consistency.
-- Removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
-- Style: style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
-- BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild().

-- Word-wrapping: Fixed a bug where we never wrapped after a 1 character word. [@sronsse]
-- Word-wrapping: Fixed TextWrapped() overriding wrap position if one is already set. (#690)

------------------------------------------------------------------------
- VERSION 1.49 (2016-05-09)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.49
-
-Breaking Changes:
-
-- Renamed `SetNextTreeNodeOpened()` to `SetNextTreeNodeOpen()` for consistency, no redirection.
-- Removed confusing set of `GetInternalState()`, `GetInternalStateSize()`, `SetInternalState()` functions. Now using `CreateContext()`, `DestroyContext()`, `GetCurrentContext()`, `SetCurrentContext()`. If you were using multiple contexts the change should be obvious and trivial.
-- Obsoleted old signature of `CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false)`, as extra parameters were badly designed and rarely used. Most uses were using 1 parameter and shouldn't affect you. You can replace the "default_open = true" flag in new API with `CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen)`.
-- Changed `ImDrawList::PushClipRect(ImVec4 rect)` to `ImDraw::PushClipRect(ImVec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false)`. Note that higher-level `ImGui::PushClipRect()` is preferable because it will clip at logic/widget level, whereas `ImDrawList::PushClipRect()` only affect your renderer.
-- Title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore (see #655). If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you. However if your TitleBg/TitleBgActive alpha was <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
- This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color. (Or If this is confusing, just pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.)
-
- ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col)
- {
- float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w));
- float k = title_bg_col.w / new_a;
- return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a);
- }
-
-Other changes:
-
-- New version of ImGuiListClipper helper calculates item height automatically. See comments and demo code. (#662, #661, #660)
-- Added SetNextWindowSizeConstraints() to enable basic min/max and programmatic size constraints on window. Added demo. (#668)

-- Added ImGuiTreeNodeFlags_Bullet flag, to add a bullet to Leaf node or replace Arrow with a bullet.
-- Added TreeAdvanceToLabelPos(), GetTreeNodeToLabelSpacing() helpers. (#581, #324)
-- Added CreateContext()/DestroyContext()/GetCurrentContext()/SetCurrentContext(). Obsoleted nearly identical GetInternalState()/SetInternalState() functions. (#586, #269)
-- Added NewLine() to undo a SameLine() and as a shy reminder that horizontal layout support hasn't been implemented yet.
-- Added IsItemClicked() helper. (#581)
-- Added CollapsingHeader() variant with close button. (#600)
-- Fixed MenuBar missing lower border when borders are enabled.
-- InputText(): Fixed clipping of cursor rendering in case it gets out of the box (which can be forced w/ ImGuiInputTextFlags_NoHorizontalScroll. (#601)
-- Style: Changed default IndentSpacing from 22 to 21. (#581, #324)
-- Style: Fixed TitleBg/TitleBgActive color being rendered above WindowBg color, which was inconsistent and causing visual artifact. (#655)
- This broke the meaning of TitleBg and TitleBgActive. Only affect values where Alpha<1.0f. Fixed default theme. Read comments in "API BREAKING CHANGES" section to convert.
-- Relative rendering of order of Child windows creation is preserved, to allow more control with overlapping children. (#595)
-- Fixed GetWindowContentRegionMax() being off by ScrollbarSize amount when explicit SizeContents is set.
-- Indent(), Unindent(): optional non-default indenting width. (#324, #581)
-- Bullet(), BulletText(): Slightly bigger. Less polygons.
-- ButtonBehavior(): fixed subtle old bug when a repeating button would also return true on mouse release (barely noticeable unless RepeatRate is set to be very slow). (#656)
-- BeginMenu(): a menu that becomes disabled while open gets closed down, facilitate user's code. (#126)
-- BeginGroup(): fixed using within Columns set. (#630)
-- Fixed a lag in reading the currently hovered window when dragging a window. (#635)
-- Obsoleted 4 parameters version of CollapsingHeader(). Refactored code into TreeNodeBehavior. (#600, #579)
-- Scrollbar: minor fix for top-right rounding of scrollbar background when window has menu bar but no title bar.
-- MenuItem(): the check mark renders in disabled color when menu item is disabled.
-- Fixed clipping rectangle floating point representation to ensure renderer-side float point operations yield correct results in typical DirectX/GL settings. (#582, 597)
-- Fixed GetFrontMostModalRootWindow(), fixing missing fade-out when a combo pop was used stacked over a modal window. (#604)
-- ImDrawList: Added AddQuad(), AddQuadFilled() helpers.
-- ImDrawList: AddText() refactor, moving some code to ImFont, reserving less unused vertices when large vertical clipping occurs.
-- ImFont: Added RenderChar() helper.
-- ImFont: Added AddRemapChar() helper. (#609)
-- ImFontConfig: Clarified persistence requirement of GlyphRanges array. (#651)
-- ImGuiStorage: Added bool helper functions for completeness.
-- AddFontFromMemoryCompressedTTF(): Fix ImFontConfig propagation. (#587)
-- Renamed majority of use of the word "opened" to "open" for clarity. Renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(). (#625, #579)
-- Examples: OpenGL3: Saving/restoring glActiveTexture() state. (#602)
-- Examples: DirectX9: save/restore all device state.
-- Examples: DirectX9: Removed dependency on d3dx9.h, d3dx9.lib, dxguid.lib so it can be used in a DirectXMath.h only environment. (#611)

- VERSION 1.48 (2016-04-09)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.48
-
-Breaking Changes:
-
-- Consistently honoring exact width passed to PushItemWidth() (when positive), previously it would add extra FramePadding.x*2 over that width. Some hand-tuned layout may be affected slightly. (#346)
-- Style: removed `style.WindowFillAlphaDefault` which was confusing and redundant, baked alpha into `ImGuiCol_WindowBg` color. If you had a custom WindowBg color but didn't change WindowFillAlphaDefault, multiply WindowBg alpha component by 0.7. Renamed `ImGuiCol_TooltipBg` to `ImGuiCol_PopupBG`, applies to other types of pop-ups. `bg_alpha` parameter of 5-parameters version of Begin() is an override. (#337)
-- InputText(): Added BufTextLen field in ImGuiTextEditCallbackData. Requesting user to update it if the buffer is modified in the callback. Added a temporary length-check assert to minimize panic for the 3 people using the callback. (#541)
-- Renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). (#340)
-
-Other Changes:
-
-- Consistently honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. Some hand-tuned layout may be affected slightly. (#346)
-- Fixed clipping of child windows within parent not taking account of child outer clipping boundaries (including scrollbar, etc.). (#506)
-- TextUnformatted(): Fixed rare crash bug with large blurb of text (2k+) not finished with a '\n' and fully above the clipping Y line. (#535)
-- IO: Added 'KeySuper' field to hold CMD keyboard modifiers for OS X. Updated all examples accordingly. (#473)

-- Added GetFontTexUvWhitePixel() helper, convenient for direct use of ImDrawList api.
-- Selectable(): Added ImGuiSelectableFlags_AllowDoubleClick flag to allow user reacting on double-click. (@zapolnov) (#516)
-- Begin(): made the close button explicitly set the boolean to false instead of toggling it. (#499)
-- BeginChild()/EndChild(): fixed incorrect layout to allow widgets submitted after an auto-fitted child window. (#540)
-- BeginChild(): Added ImGuiWindowFlags_AlwaysUseWindowPadding flag to ensure non-bordered child window uses window padding. (#462)
-- Fixed InputTextMultiLine(), ListBox(), BeginChildFrame(), ProgressBar(): outer frame not honoring bordering. (#462, #503)
-- Fixed Image(), ImageButtion() rendering a rectangle 1 px too large on each axis. (#457)
-- SetItemAllowOverlap(): Promoted from imgui_internal.h to public imgui.h api. (#517)
-- Combo(): Right-most button stays highlighted when pop-up is open.
-- Combo(): Display pop-up above if there's isn't enough space below / or select largest side. (#505)
-- DragFloat(), SliderFloat(), InputFloat(): fixed cases of erroneously returning true repeatedly after a text input modification (e.g. "0.0" --> "0.000" would keep returning true). (#564)
-- DragFloat(): Always apply value when mouse is held/widget active, so that an always-resetting variable (e.g. non saved local) can be passed.
-- InputText(): OS X friendly behaviors: Word movement uses ALT key; Shortcuts uses CMD key; Double-clicking text select a single word; Jumping to next word sets cursor to end of current word instead of beginning of current word. (@zhiayang), (#473)
-- InputText(): Added BufTextLen in ImGuiTextEditCallbackData. Requesting user to maintain it if buffer is modified. Zero-ing structure properly before use. (#541)
-- CheckboxFlags(): Added support for testing/setting multiple flags at the same time. (@DMartinek) (#555)
-- TreeNode(), CollapsingHeader() fixed not being able to use "##" sequence in a formatted label.
-- ColorEdit4(): Empty label doesn't add InnerSpacing.x, matching behavior of other widgets. (#346)
-- ColorEdit4(): Removed unnecessary calls to scanf() when idle in hexadecimal edit mode.
-- BeginPopupContextItem(), BeginPopupContextWindow(): added early out optimization.
-- CaptureKeyboardFromApp() / CaptureMouseFromApp(): added argument to allow clearing the capture flag. (#533)
-- ImDrawList: Fixed index-overflow check broken by AddText() casting current index back to ImDrawIdx. (#514)
-- ImDrawList: Fixed incorrect removal of trailing draw command if it is a callback command.
-- ImDrawList: Allow windows with only a callback only to be functional. (#524)
-- ImDrawList: Fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. (#457)

- VERSION 1.45 (2015-09-01)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.45
-
-Breaking Changes:
-
-- With the addition of better horizontal scrolling primitives I had to make some consistency fixes.
- `GetCursorPos()` `SetCursorPos()` `GetContentRegionMax()` `GetWindowContentRegionMin()` `GetWindowContentRegionMax()`
- are now incorporating the scrolling amount. They were incorrectly not incorporating this amount previously.
- It PROBABLY shouldn't break anything, but that depends on how you used them. Namely:
- - If you always used SetCursorPos() with values relative to GetCursorPos() there shouldn't be a problem.
- However if you used absolute coordinates, note that SetCursorPosY(100.0f) will put you at +100 from the initial Y position (which may be scrolled out of the view), NOT at +100 from the window top border. Since there wasn't any official scrolling value on X axis (past just manually moving the cursor) this can only affect you if you used to set absolute coordinates on the Y axis which is hopefully rare/unlikely, and trivial to fix.
- - The value of GetWindowContentRegionMax() isn't necessarily close to GetWindowWidth() if horizontally scrolling.
- Previously they were roughly interchangeable (roughly because the content region exclude window padding).
-
-Other Changes:
-
-- Added Horizontal Scrollbar via ImGuiWindowFlags_HorizontalScroll (#246).
-- Added GetScrollX(), GetScrollX(), GetScrollMaxX() apis (#246).
-- Added SetNextWindowContentSize(), SetNextWindowContentWidth() to explicitly set the content size of a window, which
- define the range of scrollbar. When set explicitly it also define the base value from which widget width are derived.
-- Added IO.WantTextInput telling when ImGui is expecting text input, so that e.g. OS on-screen keyboard can be enabled.
-- Added printf attribute to printf-like text formatting functions (Clang/GCC).
-- Added GetMousePosOnOpeningCurrentPopup() helper.
-- Added GetContentRegionAvailWidth() helper.
-- Malformed UTF-8 data don't terminate string, output 0xFFFD instead (#307).
-- ImDrawList: Added AddBezierCurve(), PathBezierCurveTo() API for cubic bezier curves (#311).
-- ImDrawList: Allow to override ImDrawIdx type (#292).
-- ImDrawList: Added an assert on overflowing index value (#292).
-- ImDrawList: Fixed issues with channels split/merge. Now functional without manually adding a draw cmd. Added comments.
-- ImDrawData: Added ScaleClipRects() helper useful when rendering scaled. (#287).
-- Fixed Bullet() inconsistent layout behaviour when clipped.
-- Fixed IsWindowHovered() not taking account of window hoverability (may be disabled because of a popup).
-- Fixed InvisibleButton() not honoring negative size consistently with other widgets that do so.
-- Fixed OpenPopup() accessing current window, effectively opening "Debug" when called from an empty window stack.
-- TreeNode(): Fixed IsItemHovered() result being inconsistent with interaction visuals (#282).
-- TreeNode(): Fixed mouse interaction padding past the node label being accounted for in layout (#282).
-- BeginChild(): Passing a ImGuiWindowFlags_NoMove inhibits moving parent window from this child.
-- BeginChild() fixed missing rounding for child sizes which leaked into layout and have items misaligned.
-- Begin(): Removed default name = "Debug" parameter. We already have a "Debug" window pushed to the stack in the first place so it's not really a useful default.
-- Begin(): Minor fixes with windows main clipping rectangle (e.g. child window with border).
-- Begin(): Window flags are only read on the first call of the frame. Subsequent calls ignore flags, which allows appending to a window without worryin about flags.
-- InputText(): ignore character input when ctrl/alt are held. (Normally those text input are ignored by most wrappers.) (#279).
-- Demo: Fixed incorrectly formed string passed to Combo (#298).
-- Demo: Added simple Log demo.
-- Demo: Added horizontal scrolling example + enabled in console, log and child examples (#246).
-- Style: made scrollbars rounded by default. Because nice. Minor menu bar background alpha tweak. (#246)
-- Metrics: display indices along with triangles count (#299) and some internal state.
-- ImGuiTextFilter::PassFilter() supports string range. Added [] helper to ImGuiTextBuffer.
-- ImGuiTextFilter::Draw() default parameter width=0.0f for no override, allow override with negative values.
-- Examples: OpenGL2/OpenGL3: fix for retina displays. Default font current lack crispness.
-- Examples: OpenGL2/OpenGL3: save/restore more GL state correctly.
-- Examples: DirectX9/DirectX11: resizing buffers dynamically (#299).
-- Examples: DirectX9/DirectX11: added missing middle mouse button to Windows event handler.
-- Examples: DirectX11: fix for Visual Studio 2015 presumably shipping with an updated version of DX11.
-- Examples: iOS: fixed missing files in project.

- VERSION 1.44 (2015-08-08)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.44
-
-Breaking Changes:
-
-- imgui.cpp has been split intro extra files: imgui_demo.cpp, imgui_draw.cpp, imgui_internal.h.
- Add the two extra .cpp to your project or #include them from another .cpp file. (#219)
-
-Other Changes:
-
-- Internal data structure and several useful functions are now exposed in imgui_internal.h. This should make it easier
- and more natural to extend ImGui. However please note that none of the content in imgui_internal.h is guaranteed
- for forward-compatibility and code using those types/functions may occasionally break. (#219)
-- All sample code is in imgui_demo.cpp. Please keep this file in your project and consider allowing your code to call
- the ShowTestWindow() function as de-facto guide to ImGui features. It will be stripped out by the linker when unused.
-- Added GetContentRegionAvail() helper (basically GetContentRegionMax() - GetCursorPos()).
-- Added ImGuiWindowFlags_NoInputs for totally input-passthru window.
-- Button(): honor negative size consistently with other widgets that do so (width -100 to align the button 100 pixels
- before the right-most position of the contents region).
-- InputTextMultiline(): honor negative size consistently with other widgets that do so.
-- Combo() clamp popup to lower edge of visible area.
-- InputInt(): value doesn't pass through an int>float>int casting chain, fix handling lost of precision with "large" integer.
-- InputInt() allow hexadecimal input (awkwardly via ImGuiInputTextFlags_CharsHexadecimal but we will allow format
- string in InputInt* later).
-- Checkbox(), RadioButton(): fixed scaling of checkbox and radio button for the filling of "active" visual.
-- Columns: never assume horizontal space for scrollbar if NoScrollbar flag is explicitly set.
-- Slider: fixed using FramePadding between frame and grab visual. Scaling that spacing would look odd.
-- Fixed lower-right resize grip hit box not scaling along with its rendered size (#287)
-- ImDrawList: Fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (v1.43) being off by an extra PI for no reason.
-- ImDrawList: Added ImDrawList::AddText() shorthand helper.
-- ImDrawList: Add missing support for anti-aliased thick-lines (#133, also ref #288)
-- ImFontAtlas: Added AddFontFromMemoryCompressedBase85TTF() to load base85 encoded font string. Default font encoded
- as base85 saves ~100 lines / 26 KB of source code. Added base85 output to the binary_to_compressed_c tool.
-- Build fix for MinGW (#276).
-- Examples: OpenGL3: Fixed running on script core profiles for OSX (#277).
-- Examples: OpenGL3: Simplified code using glBufferData for vertices as well (#277, #278)
-- Examples: DirectX11: Clear font texture view to ensure Release() doesn't get called twice (#290).
-- Updated to stb_truetype 1.07 (back to vanilla version as our minor changes are now in master & fix unlikely assert
- with odd fonts (#280)
-
-
------------------------------------------------------------------------
- VERSION 1.43 (2015-07-17)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.43
-
-Breaking Changes:
-
-- This is a rather important release and we unfortunately had to break the rendering API.
- ImGui now requires you to render indexed vertices instead of non-indexed ones. The fix should be very easy.
- Sorry for that! This change is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
- Each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles
- using indices from the index buffer.
-- If you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update
- your copy and you can ignore the rest.
-- The signature of the io.RenderDrawListsFn handler has changed
- From: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
- To: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data)
- With: argument 'cmd_lists' -> 'draw_data->CmdLists'
- argument 'cmd_lists_count' -> 'draw_data->CmdListsCount'
- ImDrawList 'commands' -> 'CmdBuffer'
- ImDrawList 'vtx_buffer' -> 'VtxBuffer'
- ImDrawList n/a -> 'IdxBuffer' (new)
- ImDrawCmd 'vtx_count' -> 'ElemCount'
- ImDrawCmd 'clip_rect' -> 'ClipRect'
- ImDrawCmd 'user_callback' -> 'UserCallback'
- ImDrawCmd 'texture_id' -> 'TextureId'
-- If you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index
- the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
- Refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. Please upgrade!
-
-Other Changes:
-
-- Added anti-aliasing on lines and shapes based on primitives by @MikkoMononen (#133).
- Between the use of indexed-rendering and the fact that the entire rendering codebase has been optimized and massaged
- enough, with anti-aliasing enabled ImGui 1.43 is now running FASTER than 1.41.
- Made some extra effort in making the code run faster in your typical Debug build.
-- Anti-aliasing can be disabled in the ImGuiStyle structure via the AntiAliasedLines/AntiAliasedShapes fields for further gains.
-- ImDrawList: Added AddPolyline(), AddConvexPolyFilled() with optional anti-aliasing.
-- ImDrawList: Added stateful path building and stroking API. PathLineTo(), PathArcTo(), PathRect(), PathFill(), PathStroke()
- with optional anti-aliasing.
-- ImDrawList: Added AddRectFilledMultiColor() helper.
-- ImDrawList: Added multi-channel rendering so out of order elements can be rendered in separate channels and then merged
- back together (used by columns).
-- ImDrawList: Fixed merging draw commands when equal clip rectangles are in the two first commands.
-- ImDrawList: Fixed window draw lists not destructed properly on Shutdown().
-- ImDrawData: Added DeIndexAllBuffers() helper.
-- Added lots of new font options ImFontAtlas::AddFont() and the new ImFontConfig structure.
- - Added support for oversampling (ImFontConfig: OversampleH, OversampleV) and sub-pixel positioning (ImFontConfig: PixelSnapH).
- Oversampling allows sub-pixel positioning but can also be used as a way to get some leeway with scaling fonts without re-rasterizing.
- - Added GlyphExtraSpacing option to add extra horizontal spacing between characters (#242).
- - Added MergeMode option to merge glyphs from different font inputs into a same font (#182, #232).
- - Added FontDataOwnedByAtlas option to keep ownership from the TTF data buffer and request the atlas to make a copy (#220).
-- Updated to stb_truetype 1.06 (+ minor mods) with better font rasterization.
-- InputText: Added ImGuiInputTextFlags_NoHorizontalScroll flag.
-- InputText: Added ImGuiInputTextFlags_AlwaysInsertMode flag.
-- InputText: Added HasSelection() helper in ImGuiTextEditCallbackData as a clarification.
-- InputText: Fix for using END key on a multi-line text editor (#275)
-- Columns: Dispatch render of each column in a sub-draw list and merge on closure, saving a lot of draw calls! (#125)
-- Popups: Fixed Combo boxes inside menus. (#272)
-- Style: Added GrabRounding setting to make the sliders etc. grabs rounded.
-- Changed SameLine() parameters from int to float.
-- Fixed incorrect assert triggering when code stole ActiveID from user moving a window by calling e.g. SetKeyboardFocusHere().
-- Fixed CollapsingHeader() label rendering outside its frame in columns context where ClipRect max isn't aligned with the
- right-side of the header.
-- Metrics window: calculate bounding box of actual vertices when hovering a draw list.
-- Examples: Showing more information in the Fonts section.
-- Examples: Added a gratuitous About window.
-- Examples: Updated all examples code (OpenGL/DX9/DX11/SDL/Allegro/iOS) to use indexed rendering.
-- Examples: Fixed the SDL2 example to support Unicode text input (#274).

- VERSION 1.42 (2015-07-08)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.42
-
-Breaking Changes:
-
-- Renamed SetScrollPosHere() to SetScrollHere(). Kept inline redirection function (will obsolete).
-- Renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion and make scrolling API consistent,
- because positions (e.g. cursor position) are not equivalent to scrolling amount.
-- Removed obsolete GetDefaultFontData() function that would assert anyway.
- If you are updating from <1.30 you'll get a compile error instead of an assertion. (obsoleted 2015/01/11)
-
-Other Changes:
-
-- Added SDL2 example application (courtesy of @CedricGuillemet)
-- Added iOS example application (courtesy of @joeld42)
-- Added Allegro 5 example application (courtesy of @bggd)
-- Added TitleBgActive color in style so focused window is made visible. (#253)
-- Added CaptureKeyboardFromApp() / CaptureMouseFromApp() to manually enforce inputs capturing.
-- Added DragFloatRange2() DragIntRange2() helpers. (#76)
-- Added a Y centering ratio to SetScrollFromCursorPos() which can be used to aim the top or bottom of the window. (#150)
-- Added SetScrollY(), SetScrollFromPos(), GetCursorStartPos() for manual scrolling manipulations. (#150).
-- Added GetKeyIndex() helper for converting from ImGuiKey_\* enum to user's keycodes. Basically pulls from io.KeysMap[].
-- Added missing ImGuiKey_PageUp, ImGuiKey_PageDown so more UI code can be written without referring to implementation-side keycodes.
-- MenuItem() can be activated on release. (#245)
-- Allowing NewFrame() with DeltaTime==0.0f to not assert.
-- Fixed IsMouseDragging(). (#260)
-- Fixed PlotLines(), PlotHistogram() using incorrect hovering test so they would show their tooltip even when there is
- a popup between mouse and the graph.
-- Fixed window padding being reported incorrectly for child windows with borders when parent have no borders.
-- Fixed a bug with TextUnformatted() clipping of long text blob when clipping y1 line sits on the first line of text. (#257)
-- Fixed text baseline alignment of small button (no padding) after regular buttons.
-- Fixed ListBoxHeader() not honoring negative sizes the same way as BeginChild() or BeginChildFrame(). (#263)
-- Fixed warnings for more pedantic compiler settings (#258).
-- ImVector<> cannot be re-defined anymore, cannot be replaced with std::vector<>. Allowed us to clean up and optimize
- lots of code. Yeah! (#262)
-- ImDrawList: store pointer to their owner name for easier auditing/debugging.
-- Examples: added scroll tracking example with SetScrollFromCursorPos().
-- Examples: metrics windows render clip rectangle when hovering over a draw call.
-- Lots of small optimization (particularly to run faster on unoptimized builds) and tidying up.
-- Added font links in extra_fonts/ + instructions for using compressed fonts in C array.

- VERSION 1.41 (2015-06-26)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.41
-
-Breaking Changes:
-
-- Changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent).
- Only makes a difference when texture have transparency.
-- Changed Selectable() API from (label, selected, size) to (label, selected, flags, size).
- Size override should be used very rarely so hopefully it doesn't affect many people. Sorry!
-
-Other Changes:
-
-- Added InputTextMultiline() multi-line text editor, vertical scrolling, selection, optimized enough to handle rather
- big chunks of text in stateless context (thousands of lines are ok), option for allowing Tab to be input, option
- for validating with Return or Ctrl+Return (#200).
-- Added modal window API, BeginPopupModal(), follows the popup api scheme. Modal windows can be closed by clicking
- outside. By default the rest of the screen is dimmed (using ImGuiCol_ModalWindowDarkening). Modal windows can be stacked.
-- Added GetGlyphRangesCyrillic() helper (#237).
-- Added SetNextWindowPosCenter() to center a window prior to knowing its size. (#249)
-- Added IsWindowHovered() helper.
-- Added IsMouseReleased(), IsKeyReleased() helpers to allow to user to avoid tracking them. (#248)
-- Allow Set*WindowSize() calls to be used with popups.
-- Window: AutoFit can be triggered on each axis separately via SetNextWindowSize(), etc.
-- Window: fixed scrolling with mouse wheel while window was collapsed.
-- Window: fixed mouse wheel scroll issues.
-- DragFloat(), SliderFloat(): Fixed rounding of negative numbers which sometime made the negative lower bound unreachable.
-- InputText(): lifted character count limit.
-- InputText(): fixes in case of using per-window font scaling.
-- Selectable(), MenuItem(): do not use frame rounding for hovering/selection.
-- Selectable(): Added flag ImGuiSelectableFlags_DontClosePopups.
-- Selectable(): Added flag ImGuiSelectableFlags_SpanAllColumns (#125).
-- Combo(): Fixed issue with activating a Combo() not taking active id (#241).
-- ColorButton(), ColorEdit4(): fix to ensure that the colored square stays square when non-default padding settings are used.
-- BeginChildFrame(): returns bool like BeginChild() for clipping.
-- SetScrollPosHere(): takes account of item height + more accurate centering + fixed precision issue.
-- ImFont: ignoring '\r'.
-- ImFont: added GetCharAdvance() helper. Exposed font Ascent and font Descent.
-- ImFont: additional rendering optimizations.
-- Metrics windows display storage size.

- VERSION 1.40 (2015-05-31)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.40
-
-Breaking Changes:
-
-- The BeginPopup() API (introduced in 1.37) had to be changed to allow for stacked popups and menus.
- Use OpenPopup() to toggle the opened state and BeginPopup() to append.**
-- The third parameter of Button(), 'repeat_if_held' has been removed. While it's been very rarely used,
- some code will possibly break if you didn't rely on the default parameter.
- Use PushButtonRepeat()/PopButtonRepeat() to configure repeat.
-- Renamed IsRectClipped() to !IsRectVisible() for consistency (opposite return value!). Kept inline redirection function (will obsolete)
-- Renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline indirection function (will obsolete).
-
-Other Changes:
-
-- Menus: Added a menu system! Menus are typically populated with menu items and sub-menus, but you can add any sort of
- widgets in them (buttons, text inputs, sliders, etc.). (#126)
-- Menus: Added MenuItem() to append a menu item. Optional shortcut display, acts a button & toggle with checked/unchecked state,
- disabled mode. Menu items can be used in any window.
-- Menus: Added BeginMenu() to append a sub-menu. Note that you generally want to add sub-menu inside a popup or a menu-bar.
- They will work inside a normal window but it will be a bit unusual.
-- Menus: Added BeginMenuBar() to append to window menu-bar (set ImGuiWindowFlags_MenuBar to enable).
-- Menus: Added BeginMainMenuBar() helper to append to a fullscreen main menu-bar.
-- Popups: Support for stacked popups. Each popup level inhibit inputs to lower levels. The menus system is based on this. (#126).
-- Popups: Added BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid() to create a popup window on mouse-click.
-- Popups: Popups have borders by default (#197), attenuated border alpha in default theme.
-- Popups & Tooltip: Fit within display. Handling various positioning/sizing/scrolling edge cases. Better hysteresis when moving
- in corners. Tooltip always tries to stay away from mouse-cursor.
-- Added ImGuiStorage::GetVoidPtrRef() for manipulating stored void*.
-- Added IsKeyDown() IsMouseDown() as convenience and for consistency with existing functions (instead of reading them from IO structures).
-- Added Dummy() helper to advance layout by a given size. Unlike InvisibleButton() this doesn't catch any click.
-- Added configurable io.KeyRepeatDelay, io.KeyRepeatRate keyboard and mouse repeat rate.
-- Added PushButtonRepeat() / PopButtonRepeat() to enable hold-button-to-repeat press on any button.
-- Removed the third 'repeat' parameter of Button().
-- Added IsAnyItemHovered() helper.
-- Added GetItemsLineHeightWithSpacing() helper.
-- Added ImGuiListClipper helper for clipping large list of evenly sized items, to avoid using CalcListClipping() directly.
-- Separator: within group start on group horizontal offset. (#205)
-- InputText: Fixed incorrect edit state after text buffer is appended to by user via the callback. (#206)
-- InputText: CTRL+letter-key shortcuts (e.g. CTRL+C/V/X) makes sure only CTRL is pressed. (#214)
-- InputText: Fixed cursor generating a zero-width wire-frame rectangle turning into a division by zero (would go unnoticed
- unless you trapped exceptions).
-- InputFloatN/InputIntN: Flags parameter added to match scalar versions. (#218)
-- Selectable: Horizontal filling not declared to ItemSize() so Selectable(),SameLine() works and we can better auto-fit the window.
-- Selectable: Handling text baseline alignment for line that aren't of text height.
-- Combo: Empty label doesn't add ItemInnerSpacing alignment, matching other widgets.
-- EndGroup: Carries the text base offset from the last line of the group (sort of incorrect but better than nothing,
- should use the first line of the group, will implement in the future).
-- Columns: distinguish columns-set ID from other widgets as a convenience, added asserts and sailors.
-- ListBox: ListBox() function only use public API to encourage creating custom versions. ListBoxHeader() can return false.
-- ListBox: Uses ImGuiListClipper and assume items of matching height, so large lists can be handled.
-- Plot: overlay label clipped within frame when not fitting.
-- Window: Added ImGuiSetCond_Appearing to test the hidden->visible transition in SetWindow***/SetNextWindow*** functions.
-- Window: Auto-fitting cancel out one worth of vertical spacing for vertical symmetry (like what group and tooltip do).
-- Window: Default item width for auto-resizing windows expressed as a factor of font height, scales better with different font.
-- Window: Fixed auto-fit calculation mismatch of whether a scrollbar will be added by maximum height clamping. Also honor NoScrollBar in the case of height clamping, not adding extra horizontal space.
-- Window: Hovering require to hover same child window. Reverted 860cf57 (December 3). Might break something if you have
- child overlapping items in parent window.
-- Window: Fixed appending multiple times to an existing child via multiple BeginChild/EndChild calls to same child name.
- Allows a simple form of out-of-order appending.
-- Window: Fixed auto-filling child window using WindowMinSize at their minimum size, irrelevant.
-- Metrics: Added io.MetricsActiveWindows counter. (#213.
-- Metrics: Added io.MetricsAllocs counter (number of active memory allocations).
-- Metrics: ShowMetricsWindow() shows popups stack, allocations.
-- Style: Added style.DisplayWindowPadding to prevent windows from reaching edges of display (similar to style.DisplaySafeAreaPadding which is still in effect and also affect popups/tooltips).
-- Style: Removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
-- Style: Added style.ScrollbarRounding. (#212)
-- Style: Added ImGuiCol_TextDisabled for disabled text. Added TextDisabled() helper.
-- Style: Added style.WindowTitleAlign alignment options, to e.g. center title on windows. (#222)
-- ImVector: tweak growth strategy, matches vector from VS2010.
-- ImFontAtlas: Added ClearFonts(), making the different clear funcs more explicit. (#224)
-- ImFontAtlas: Fixed appending new fonts without clearing existing fonts. Clearing input data left to application. (#224)
-- ImDrawList: Merge draw command better, cases of multiple Begin/End gets merged properly.
-- Store common stacked settings contiguously in memory to avoid heap allocation for unused features, and reduce cache misses.
-- Shutdown() tests for g.IO.Fonts not being NULL to ease use of multiple ImGui contexts. (#207)

-- Examples: Added Menu-bar example.
-- Examples: Added Simple Layout example.
-- Examples: AutoResize demo doesn't use TextWrapped().
-- Examples: Console example uses standard malloc/free, makes more sense as a copy & pastable example.

-- Examples: DirectX9/11: hide OS cursor if ImGui is drawing it. (#155)
-- Examples: DirectX11: explicitly set rasterizer state.
-- Examples: OpenGL3: Add conditional compilation of forward compat as required by glfw on OSX. (#229)

-- InputText: cursor/selection/undo stack persist when using other widgets and getting back to same (#134).
-- InputText: fix effective buffer size being smaller than necessary by 1 byte (so if you give 3 bytes you can input 2 ascii chars + zero terminator, which is correct).
-- Added IsAnyItemActive().
-- Child window explicitly inherit collapse state from parent (so if user keeps submitting items even thought Begin has returned 'false' the child items will be clipped faster).
-- BeginChild() return a bool the same way Begin() does. if true you can skip submitting content.

- VERSION 1.30 (2015-02-01)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.30
-
-Breaking Changes:
-
-- Big update! Initialisation had to be changed. You don't need to load PNG data anymore. The new system gives you uncompressed texture data.
- - This sequence:
- const void* png_data;
- unsigned int png_size;
- ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size);
- //
- - Became:
- unsigned char* pixels;
- int width, height;
- // io.Fonts->AddFontFromFileTTF("myfontfile.ttf", 24.0f); // Optionally load another font
- io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
- //
- io.Fonts->TexID = (your_texture_identifier);
- - PixelCenterOffset has been removed and isn't a necessary setting anymore. Offset your projection matrix by 0.5 if you have rendering problems.
-
-Other Changes:
-
-- Loading TTF files with stb_truetype.h.
-- We still embed a compressed pixel-perfect TTF version of ProggyClean for convenience.
-- Runtime font rendering is a little faster than previously.
-- You can load multiple fonts with multiple size inside the font atlas. Rendering with multiple fonts are still merged into a single draw call whenever possible.
-- The system handles UTF-8 and provide ranges to easily load e.g. characters for Japanese display.
-- Added PushFont() / PopFont().
-- Added Image() and ImageButton() to display your own texture data.
-- Added callback system in command-list. This can be used if you want to do your own rendering (e.g. render a 3D scene) inside ImGui widgets.
-- Added IsItemActive() to tell if last widget is being held / modified (as opposed to just being hovered). Useful for custom dragging behaviors.
-- Style: Added FrameRounding setting for a more rounded look (default to 0 for now).
-- Window: Fixed using multiple Begin/End pair on the same wnidow.
-- Window: Fixed style.WindowMinSize not being honored properly.
-- Window: Added SetCursorScreenPos() helper (WindowPos+CursorPos = ScreenPos).
-- ColorEdit3: clicking on color square change the edition. The toggle button is hidden by default.
-- Clipboard: Fixed logging to clipboard on architectures where va_list are passed by reference to vsnprintf.
-- Clipboard: Improve memory reserve policy for Clipboard / ImGuiTextBuffer.
-- Tooltip: Always auto-resize.
-- Tooltip: Fixed TooltigBg color not being honored properly.
-- Tooltip: Allow SetNextWindowPos() to be used on tooltips.
-- Added io.DisplayVisibleMin / io.DisplayVisibleMax to ease integration of virtual / scrolling display.
-- Added Set/GetVoidPtr in ImGuiStorage.
-- Added ColorConvertHSVtoRGB, ColorConvertRGBtoHSV, ColorConvertFloat4ToU32 helpers.
-- Added ImColor() inline helper to easily convert colors to packed 4x1 byte or 4x1 float formats.
-- Added io.MouseDrawCursor option to draw a mouse cursor for now (on systems that don't have one)
-- Examples: Added custom drawing app example for using ImDrawList api.
-- Lots of others fixes, tweaks and comments!

-- Examples: Added DirectX11 example application.
-- Examples: Created single .sln solution for all example projects.
-- Examples: Fixed DirectX9 example window initially showing an hourglass cursor.
-- Examples: Removed Microsoft IME handler in examples, too niche/confusing. Moved equivalent code to imgui.cpp instruction block.

- VERSION 1.09 (2014-08-28)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.09
-
-Breaking Changes:
-
-- The behaviour of PixelCenterOffset changed! You may need to change your value if you had set it to non-default in your code and/or offset your projection matrix by 0.5 pixels.

-
-Other Changes:
-
-- Various minor render tweaks and fixes. Better support for renderers using multisampling.
-- Moved IMGUI_FONT_TEX_UV_FOR_WHITE #define to a variable in the IO structure so font can be changed at runtime.

-## Getting Started & General Advice
-
-- Article: [How To Ask Good Questions](https://bit.ly/3nwRnx1).
-- Please browse the [Wiki](https://github.com/ocornut/imgui/wiki) to find code snippets, links and other resources (e.g. [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started), [Useful extensions](https://github.com/ocornut/imgui/wiki/Useful-Extensions)).
-- Please read [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) if your question relates to setting up Dear ImGui.
-- Please read [docs/FAQ.md](https://github.com/ocornut/imgui/blob/master/docs/FAQ.md).
-- Please read [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) if your question relates to fonts or text.
-- Please run `ImGui::ShowDemoWindow()` to explore the demo and its sources.
-- Please use the search function of your IDE to search for symbols and comments related to your situation.
-- Please use the search function of GitHub to look for similar topics (always include 'Closed' issues/pr in your search).
-- You may [browse issues by Labels](https://github.com/ocornut/imgui/labels).
-- Please use a web search engine to look for similar issues.
-- If you get a crash or assert, use a debugger to locate the line triggering it and read the comments around.
-- Please don't be a [Help Vampire](https://slash7.com/2006/12/22/vampires/).
-
-## 'Issues' vs 'Discussions'
-
-We are happy to use 'Issues' for many type of open-ended questions. We are encouraging 'Issues' becoming an enormous, centralized and cross-referenced database of Dear ImGui contents.
-
-Only if you:
-- Cannot BUILD or LINK examples.
-- Cannot BUILD, or LINK, or RUN Dear ImGui in your application or custom engine.
-- Cannot LOAD a font.
-
-Then please [use the Discussions forums](https://github.com/ocornut/imgui/discussions) instead of opening an issue.
-
-If Dear ImGui is successfully showing in your app and you have used Dear ImGui before, you can open an Issue. Any form of discussions is welcome as a new issue.
-
-## How to open an issue
-
-You may use the Issue Tracker to submit bug reports, feature requests or suggestions. You may ask for help or advice as well. But **PLEASE CAREFULLY READ THIS WALL OF TEXT. ISSUES IGNORING THOSE GUIDELINES MAY BE CLOSED. USERS IGNORING THOSE GUIDELINES MIGHT BE BLOCKED.**
-
-Please do your best to clarify your request. The amount of incomplete or ambiguous requests due to people not following those guidelines is often overwhelming. Issues created without the requested information may be closed prematurely. Exceptionally entitled, impolite, or lazy requests may lead to bans.
-
-**PLEASE UNDERSTAND THAT OPEN-SOURCE SOFTWARE LIVES OR DIES BY THE AMOUNT OF ENERGY MAINTAINERS CAN SPARE. WE HAVE LOTS OF STUFF TO DO. THIS IS AN ATTENTION ECONOMY AND MANY LAZY OR MINOR ISSUES ARE HOGGING OUR ATTENTION AND DRAINING ENERGY, TAKING US AWAY FROM MORE IMPORTANT WORK.**
-
-Steps:
-
-- Article: [How To Ask Good Questions](https://bit.ly/3nwRnx1).
-- **PLEASE DO FILL THE REQUESTED NEW ISSUE TEMPLATE.** Including Dear ImGui version number, branch name, platform/renderer back-ends (imgui_impl_XXX files), operating system.
-- **Try to be explicit with your GOALS, your EXPECTATIONS and what you have tried**. Be mindful of [The XY Problem](http://xyproblem.info/). What you have in mind or in your code is not obvious to other people. People frequently discuss problems and suggest incorrect solutions without first clarifying their goals. When requesting a new feature, please describe the usage context (how you intend to use it, why you need it, etc.). If you tried something and it failed, show us what you tried.
-- **Please INCLUDE CODE. Provide a Minimal, Complete, and Verifiable Example ([MCVE](https://stackoverflow.com/help/mcve)) to demonstrate your problem**. An ideal submission includes a small piece of code that anyone can paste into one of the examples applications (examples/../main.cpp) or demo (imgui_demo.cpp) to understand and reproduce it. **Narrowing your problem to its shortest and purest form is the easiest way to understand it, explain it and fix it**. Please test your shortened code to ensure it exhibits the problem. **Often while creating the MCVE you will solve the problem!** Many questions that are missing a standalone verifiable example are missing the actual cause of their issue in the description, which ends up wasting everyone's time.
-- **Attach screenshots (or GIF/video) to clarify the context**. They often convey useful information that is omitted by the description. You can drag pictures/files in the message edit box. Avoid using 3rd party image hosting services, prefer the long-term longevity of GitHub attachments (you can drag pictures into your post). On Windows, you can use [ScreenToGif](https://www.screentogif.com/) to easily capture .gif files.
-- **If you are discussing an assert or a crash, please provide a debugger callstack**. Never state "it crashes" without additional information. If you don't know how to use a debugger and retrieve a callstack, learning about it will be useful.
-- **Please make sure that your project has asserts enabled.** Calls to IM_ASSERT() are scattered in the code to help catch common issues. When an assert is triggered read the comments around it. By default IM_ASSERT() calls the standard assert() function. To verify that your asserts are enabled, add the line `IM_ASSERT(false);` in your main() function. Your application should display an error message and abort. If your application doesn't report an error, your asserts are disabled.
-- Please state if you have made substantial modifications to your copy of Dear ImGui or the back-end.
-- If you are not calling Dear ImGui directly from C++, please provide information about your Language and the wrapper/binding you are using.
-- Be mindful that messages are being sent to the mailbox of "Watching" users. Try to proofread your messages before sending them. Edits are not seen by those users unless they browse the site.
-
-**Some unfortunate words of warning**
-- If you are involved in cheating schemes (e.g. DLL injection) for competitive online multiplayer games, please don't post here. We won't answer and you will be blocked. It doesn't matter if your question relates to said project. We've had too many of you and need to project our time and sanity.
-- Due to frequent abuse of this service from the aforementioned users, if your GitHub account is anonymous and was created five minutes ago please understand that your post will receive more scrutiny and incomplete questions will be harshly dismissed.
-
-If you have been using Dear ImGui for a while or have been using C/C++ for several years or have demonstrated good behavior here, it is ok to not fulfill every item to the letter. Those are guidelines and experienced users or members of the community will know which information is useful in a given context.
-
-## How to open a Pull Request
-
-- **Please understand that by submitting a PR you are also submitting a request for the maintainer to review your code and then take over its maintenance.** PR should be crafted both in the interest of the end-users and also to ease the maintainer into understanding and accepting it.
-- Many PRs are useful to demonstrate a need and a possible solution but aren't adequate for merging (causing other issues, not seeing other aspects of the big picture, etc.). In doubt, don't hesitate to push a PR because that is always the first step toward pointing toward a problem, and finding the mergeable solution! Even if a PR stays unmerged for a long time, its presence can be useful for other users and helps toward finding a general solution.
-- **When adding a feature,** please describe the usage context (how you intend to use it, why you need it, etc.). Be mindful of [The XY Problem](http://xyproblem.info/).
-- **When fixing a warning or compilation problem,** please post the compiler log and specify the compiler version and platform you are using.
-- **Attach screenshots (or GIF/video) to clarify the context and demonstrate the feature at a glance.** You can drag pictures/files in the message edit box. Prefer the long-term longevity of GitHub attachments over 3rd party hosting (you can drag pictures into your post).
-- **Make sure your code follows the coding style already used in the codebase:** 4 spaces indentations (no tabs), `local_variable`, `FunctionName()`, `MemberName`, `// Text Comment`, `//CodeComment();`, C-style casts, etc.. We don't use modern C++ idioms and tend to use only a minimum of C++11 features. The applications under examples/ are generally less consistent because they sometimes try to mimic the coding style often adopted by a certain ecosystem (e.g. DirectX-related code tend to use the style of their sample).
-- **Make sure you create a branch dedicated to the pull request**. In Git, 1 PR is associated to 1 branch. If you keep pushing to the same branch after you submitted the PR, your new commits will appear in the PR (we can still cherry-pick individual commits).

-## Dear ImGui: Examples
-
-**The [examples/](https://github.com/ocornut/imgui/blob/master/examples) folder example applications (standalone, ready-to-build) for variety of
-platforms and graphics APIs.** They all use standard backends from the [backends/](https://github.com/ocornut/imgui/blob/master/backends) folder (see [BACKENDS.md](https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md)).
-
-The purpose of Examples is to showcase integration with backends, let you try Dear ImGui, and guide you toward
-integrating Dear ImGui in your own application/game/engine.
-**Once Dear ImGui is setup and running, run and refer to `ImGui::ShowDemoWindow()` in imgui_demo.cpp for usage of the end-user API.**
-
-You can find Windows binaries for some of those example applications at:
- https://www.dearimgui.com/binaries
-
-
-### Getting Started
-
-Integration in a typical existing application, should take <20 lines when using standard backends.
-
-```cpp
-At initialization:
- call ImGui::CreateContext()
- call ImGui_ImplXXXX_Init() for each backend.
-
-At the beginning of your frame:
- call ImGui_ImplXXXX_NewFrame() for each backend.
- call ImGui::NewFrame()
-
-At the end of your frame:
- call ImGui::Render()
- call ImGui_ImplXXXX_RenderDrawData() for your Renderer backend.
-
-At shutdown:
- call ImGui_ImplXXXX_Shutdown() for each backend.
- call ImGui::DestroyContext()
-```
-
-Example (using [backends/imgui_impl_win32.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_win32.cpp) + [backends/imgui_impl_dx11.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp)):
-
-```cpp
-// Create a Dear ImGui context, setup some options
-ImGui::CreateContext();
-ImGuiIO& io = ImGui::GetIO();
-io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard; // Enable some options
-
-// Initialize Platform + Renderer backends (here: using imgui_impl_win32.cpp + imgui_impl_dx11.cpp)
-ImGui_ImplWin32_Init(my_hwnd);
-ImGui_ImplDX11_Init(my_d3d_device, my_d3d_device_context);
-
-// Application main loop
-while (true)
-{
- // Beginning of frame: update Renderer + Platform backend, start Dear ImGui frame
- ImGui_ImplDX11_NewFrame();
- ImGui_ImplWin32_NewFrame();
- ImGui::NewFrame();
-
- // Any application code here
- ImGui::Text("Hello, world!");
-
- // End of frame: render Dear ImGui
- ImGui::Render();
- ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());
-
- // Swap
- g_pSwapChain->Present(1, 0);
-}
-
-// Shutdown
-ImGui_ImplDX11_Shutdown();
-ImGui_ImplWin32_Shutdown();
-ImGui::DestroyContext();
-```
-
-Please read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
-Please read the comments and instruction at the top of each file.
-Please read FAQ at https://www.dearimgui.com/faq
-
-If you are using any of the backends provided here, you can add the backends/imgui_impl_xxxx(.cpp,.h)
-files to your project and use as-in. Each imgui_impl_xxxx.cpp file comes with its own individual
-Changelog, so if you want to update them later it will be easier to catch up with what changed.

-### Examples Applications
-
-[example_allegro5/](https://github.com/ocornut/imgui/blob/master/examples/example_allegro5/)
-Allegro 5 example.
-= main.cpp + imgui_impl_allegro5.cpp
-
-[example_android_opengl3/](https://github.com/ocornut/imgui/blob/master/examples/example_android_opengl3/)
-Android + OpenGL3 (ES) example.
-= main.cpp + imgui_impl_android.cpp + imgui_impl_opengl3.cpp
-
-[example_apple_metal/](https://github.com/ocornut/imgui/blob/master/examples/example_metal/)
-OSX & iOS + Metal example.
-= main.m + imgui_impl_osx.mm + imgui_impl_metal.mm
-It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
-(NB: imgui_impl_osx.mm is currently not as feature complete as other platforms backends.
-You may prefer to use the GLFW Or SDL backends, which will also support Windows and Linux.)
-
-[example_apple_opengl2/](https://github.com/ocornut/imgui/blob/master/examples/example_apple_opengl2/)
-OSX + OpenGL2 example.
-= main.mm + imgui_impl_osx.mm + imgui_impl_opengl2.cpp
-(NB: imgui_impl_osx.mm is currently not as feature complete as other platforms backends.
- You may prefer to use the GLFW Or SDL backends, which will also support Windows and Linux.)
-
-[example_emscripten_wgpu/](https://github.com/ocornut/imgui/blob/master/examples/example_emscripten_wgpu/)
-Emcripten + GLFW + WebGPU example.
-= main.cpp + imgui_impl_glfw.cpp + imgui_impl_wgpu.cpp
-Note that the 'example_glfw_opengl3' and 'example_sdl2_opengl3' examples also supports Emscripten!
-
-[example_glfw_metal/](https://github.com/ocornut/imgui/blob/master/examples/example_glfw_metal/)
-GLFW (Mac) + Metal example.
-= main.mm + imgui_impl_glfw.cpp + imgui_impl_metal.mm

-[example_glfw_opengl2/](https://github.com/ocornut/imgui/blob/master/examples/example_glfw_opengl2/)
-GLFW + OpenGL2 example (legacy, fixed pipeline).
-= main.cpp + imgui_impl_glfw.cpp + imgui_impl_opengl2.cpp
-**DO NOT USE THIS IF YOUR CODE/ENGINE IS USING MODERN GL or WEBGL (SHADERS, VBO, VAO, etc.)**
-This code is mostly provided as a reference to learn about Dear ImGui integration, because it is shorter.
-If your code is using GL3+ context or any semi modern GL calls, using this renderer is likely to
-make things more complicated, will require your code to reset many GL attributes to their initial
-state, and might confuse your GPU driver. One star, not recommended.
-
-[example_glfw_opengl3/](https://github.com/ocornut/imgui/blob/master/examples/example_glfw_opengl3/)

-### Miscellaneous
-
-**Building**
-
-Unfortunately nowadays it is still tedious to create and maintain portable build files using external
-libraries (the kind we're using here to create a window and render 3D triangles) without relying on
-third party software and build systems. For most examples here we choose to provide:
- - Makefiles for Linux/OSX
- - Batch files for Visual Studio 2008+
- - A .sln project file for Visual Studio 2012+
- - Xcode project files for the Apple examples
-Please let us know if they don't work with your setup!
-You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
-directly with a command-line compiler.
-
-If you are interested in using Cmake to build and links examples, see:
- https://github.com/ocornut/imgui/pull/1713 and https://github.com/ocornut/imgui/pull/3027
-
-**About mouse cursor latency**
-
-Dear ImGui has no particular extra lag for most behaviors,
-e.g. the last value passed to 'io.AddMousePosEvent()' before NewFrame() will result in windows being moved
-to the right spot at the time of EndFrame()/Render(). At 60 FPS your experience should be pleasant.
-
-However, consider that OS mouse cursors are typically drawn through a very specific hardware accelerated
-path and will feel smoother than the majority of contents rendered via regular graphics API (including,
-but not limited to Dear ImGui windows). Because UI rendering and interaction happens on the same plane
-as the mouse, that disconnect may be jarring to particularly sensitive users.
-You may experiment with enabling the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor
-using the regular graphics API, to help you visualize the difference between a "hardware" cursor and a
-regularly rendered software cursor.
-However, rendering a mouse cursor at 60 FPS will feel sluggish so you likely won't want to enable that at
-all times. It might be beneficial for the user experience to switch to a software rendered cursor _only_
-when an interactive drag is in progress.
-
-Note that some setup or GPU drivers are likely to be causing extra display lag depending on their settings.
-If you feel that dragging windows feels laggy and you are not sure what the cause is: try to build a simple
-drawing a flat 2D shape directly under the mouse cursor!

-# Q&A: Basics
-
-### Q: Where is the documentation?
-
-**This library is poorly documented at the moment and expects the user to be acquainted with C/C++.**
-- The [Wiki](https://github.com/ocornut/imgui/wiki) is a hub to many resources and links.
-- Handy [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) guide to integrate Dear ImGui in an existing application.
-- 20+ standalone example applications using e.g. OpenGL/DirectX are provided in the [examples/](https://github.com/ocornut/imgui/blob/master/examples/) folder to explain how to integrate Dear ImGui with your own engine/application. You can run those applications and explore them.
-- See demo code in [imgui_demo.cpp](https://github.com/ocornut/imgui/blob/master/imgui_demo.cpp) and particularly the `ImGui::ShowDemoWindow()` function. The demo covers most features of Dear ImGui, so you can read the code and see its output.
-- See documentation: [Backends](https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md), [Examples](https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md), [Fonts](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).
-- See documentation and comments at the top of [imgui.cpp](https://github.com/ocornut/imgui/blob/master/imgui.cpp) + general API comments in [imgui.h](https://github.com/ocornut/imgui/blob/master/imgui.h).
-- The [Glossary](https://github.com/ocornut/imgui/wiki/Glossary) page may be useful.
-- The [Issues](https://github.com/ocornut/imgui/issues) and [Discussions](https://github.com/ocornut/imgui/discussions) sections can be searched for past questions and issues.
-- Your programming IDE is your friend, find the type or function declaration to find comments associated with it.
-- The `ImGui::ShowMetricsWindow()` function exposes lots of internal information and tools. Although it is primarily designed as a debugging tool, having access to that information tends to help understands concepts.

-
-### Q. What is this library called?
-
-**This library is called Dear ImGui**. Please refer to it as Dear ImGui (not ImGui, not IMGUI).
-
-(The library misleadingly started its life in 2014 as "ImGui" due to the fact that I didn't give it a proper name when I released 1.0, and had no particular expectation that it would take off. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations e.g. Unity uses it own implementation of the IMGUI paradigm. To reduce the ambiguity without affecting existing code bases, I have decided in December 2015 a fully qualified name "Dear ImGui" for this library.

-
-### Q: Which version should I get?
-I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported.
-
-You may use the [docking](https://github.com/ocornut/imgui/tree/docking) branch which includes:
-- [Docking features](https://github.com/ocornut/imgui/issues/2109)
-- [Multi-viewport features](https://github.com/ocornut/imgui/issues/1542)
-
-Many projects are using this branch and it is kept in sync with master regularly.

-# Q&A: Integration
-
-### Q: How to get started?
-
-Read [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started).
-Read [EXAMPLES.md](https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md).
-Read [BACKENDS.md](https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md).
-Read `PROGRAMMER GUIDE` section of [imgui.cpp](https://github.com/ocornut/imgui/blob/master/imgui.cpp).
-The [Wiki](https://github.com/ocornut/imgui/wiki) is a hub to many resources and links.
-
-For first-time users having issues compiling/linking/running or issues loading fonts, please use [GitHub Discussions](https://github.com/ocornut/imgui/discussions).

-
-### Q: How can I tell whether to dispatch mouse/keyboard to Dear ImGui or my application?
-
-You can read the `io.WantCaptureMouse`, `io.WantCaptureKeyboard` and `io.WantTextInput` flags from the ImGuiIO structure.
-- When `io.WantCaptureMouse` is set, you need to discard/hide the mouse inputs from your underlying application.
-- When `io.WantCaptureKeyboard` is set, you need to discard/hide the keyboard inputs from your underlying application.
-- When `io.WantTextInput` is set, you can notify your OS/engine to popup an on-screen keyboard, if available (e.g. on a mobile phone, or console OS).
-
-Important: you should always pass your mouse/keyboard inputs to Dear ImGui, regardless of the value `io.WantCaptureMouse`/`io.WantCaptureKeyboard`. This is because e.g. we need to detect that you clicked in the void to unfocus its own windows, and other reasons.
-
-```cpp
-void MyLowLevelMouseButtonHandler(int button, bool down)
-{
- // (1) ALWAYS forward mouse data to ImGui! This is automatic with default backends. With your own backend:
- ImGuiIO& io = ImGui::GetIO();
- io.AddMouseButtonEvent(button, down);
-
- // (2) ONLY forward mouse data to your underlying app/game.
- if (!io.WantCaptureMouse)
- my_game->HandleMouseData(...);
-}
-```
-
-**Note:** The `io.WantCaptureMouse` is more correct that any manual attempt to "check if the mouse is hovering a window" (don't do that!). It handles mouse dragging correctly (both dragging that started over your application or over a Dear ImGui window) and handle e.g. popup and modal windows blocking inputs.
-
-**Note:** Text input widget releases focus on the "KeyDown" event of the Return key, so the subsequent "KeyUp" event that your application receive will typically have `io.WantCaptureKeyboard == false`. Depending on your application logic it may or not be inconvenient to receive that KeyUp event. You might want to track which key-downs were targeted for Dear ImGui, e.g. with an array of bool, and filter out the corresponding key-ups.)

-
-### Q: How can I enable keyboard or gamepad controls?
-- The gamepad/keyboard navigation is fairly functional and keeps being improved. The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable. Gamepad support is particularly useful to use Dear ImGui on a game console (e.g. PS4, Switch, XB1) without a mouse connected!
-- Keyboard: set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard` to enable.
-- Gamepad: set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad` to enable (with a supporting backend).
-- See [Control Sheets for Gamepads](https://www.dearimgui.com/controls_sheets) (reference PNG/PSD for PS4, XB1, Switch gamepads).
-- See `USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS` section of [imgui.cpp](https://github.com/ocornut/imgui/blob/master/imgui.cpp) for more details.

-
-### Q: How can I use this on a machine without mouse, keyboard or screen? (input share, remote display)
-- You can share your computer mouse seamlessly with your console/tablet/phone using solutions such as [Synergy](https://symless.com/synergy)
-This is the preferred solution for developer productivity.
-In particular, the [micro-synergy-client repository](https://github.com/symless/micro-synergy-client) has simple
-and portable source code (uSynergy.c/.h) for a small embeddable client that you can use on any platform to connect
-to your host computer, based on the Synergy 1.x protocol. Make sure you download the Synergy 1 server on your computer.
-Console SDK also sometimes provide equivalent tooling or wrapper for Synergy-like protocols.
-- Game console users: consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
-- You may also use a third party solution such as [netImgui](https://github.com/sammyfreg/netImgui), [Remote ImGui](https://github.com/JordiRos/remoteimgui) or [imgui-ws](https://github.com/ggerganov/imgui-ws) which sends the vertices to render over the local network, allowing you to use Dear ImGui even on a screen-less machine. See [Wiki](https://github.com/ocornut/imgui/wiki) index for most details.
-- For touch inputs, you can increase the hit box of widgets (via the `style.TouchPadding` setting) to accommodate for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimizing for screen real-estate and precision.

-### Q: I integrated Dear ImGui in my engine and little squares are showing instead of text...
-Your renderer backend is not using the font texture correctly or it hasn't been uploaded to the GPU.
-- If this happens using the standard backends: A) have you modified the font atlas after `ImGui_ImplXXX_NewFrame()`? B) maybe the texture failed to upload, which **can if your texture atlas is too big**. Also see [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).
-- If this happens with a custom backend: make sure you have uploaded the font texture to the GPU, that all shaders are rendering states are setup properly (e.g. texture is bound). Compare your code to existing backends and use a graphics debugger such as [RenderDoc](https://renderdoc.org) to debug your rendering states.

-### Q: I integrated Dear ImGui in my engine and some elements are clipping or disappearing when I move windows around...
-### Q: I integrated Dear ImGui in my engine and some elements are displaying outside their expected windows boundaries...
-You are probably mishandling the clipping rectangles in your render function.
-Each draw command needs the triangle rendered using the clipping rectangle provided in the ImDrawCmd structure (`ImDrawCmd->CllipRect`).
-Rectangles provided by Dear ImGui are defined as
-`(x1=left,y1=top,x2=right,y2=bottom)`
-and **NOT** as
-`(x1,y1,width,height)`.
-Refer to rendering backends in the [backends/](https://github.com/ocornut/imgui/tree/master/backends) folder for references of how to handle the `ClipRect` field.
-For example, the [DirectX11 backend](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp) does this:
-```cpp
-// Project scissor/clipping rectangles into framebuffer space
-ImVec2 clip_off = draw_data->DisplayPos;
-ImVec2 clip_min(pcmd->ClipRect.x - clip_off.x, pcmd->ClipRect.y - clip_off.y);
-ImVec2 clip_max(pcmd->ClipRect.z - clip_off.x, pcmd->ClipRect.w - clip_off.y);
-if (clip_max.x <= clip_min.x || clip_max.y <= clip_min.y)
- continue;
-
-// Apply scissor/clipping rectangle
-const D3D11_RECT r = { (LONG)clip_min.x, (LONG)clip_min.y, (LONG)clip_max.x, (LONG)clip_max.y };
-ctx->RSSetScissorRects(1, &r);

-# Q&A: Usage
-
-### Q: About the ID Stack system...
-### Q: Why is my widget not reacting when I click on it?
-### Q: How can I have widgets with an empty label?
-### Q: How can I have multiple widgets with the same label?
-### Q: How can I have multiple windows with the same label?
-
-A primer on labels and the ID Stack...
-
-Dear ImGui internally needs to uniquely identify UI elements.
-Elements that are typically not clickable (such as calls to the Text functions) don't need an ID.
-Interactive widgets (such as calls to Button buttons) need a unique ID.
-
-**Unique IDs are used internally to track active widgets and occasionally associate state to widgets.
-Unique IDs are implicitly built from the hash of multiple elements that identify the "path" to the UI element.**
-
-Since Dear ImGui 1.85, you can use `Demo>Tools>ID Stack Tool` or call `ImGui::ShowIDStackToolWindow()`. The tool display intermediate values leading to the creation of a unique ID, making things easier to debug and understand.
-
-
-
-- Unique ID are often derived from a string label and at minimum scoped within their host window:
-```cpp
-Begin("MyWindow");
-Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "OK")
-Button("Cancel"); // Label = "Cancel", ID = hash of ("MyWindow", "Cancel")
-End();
-```
-- Other elements such as tree nodes, etc. also pushes to the ID stack:
-```cpp
-Begin("MyWindow");
-if (TreeNode("MyTreeNode"))
-{
- Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "MyTreeNode", "OK")
- TreePop();
-}
-End();
-```
-- Two items labeled "OK" in different windows or different tree locations won't collide:
-```cpp
-Begin("MyFirstWindow");
-Button("OK"); // Label = "OK", ID = hash of ("MyFirstWindow", "OK")
-End();
-Begin("MyOtherWindow");
-Button("OK"); // Label = "OK", ID = hash of ("MyOtherWindow", "OK")
-End();
-```
-
-- If you have a same ID twice in the same location, you'll have a conflict:
-```cpp
-Begin("MyWindow");
-Button("OK");
-Button("OK"); // ERROR: ID collision with the first button! Interacting with either button will trigger the first one.
-Button(""); // ERROR: ID collision with Begin("MyWindow")!
-End();
-```
-Fear not! This is easy to solve and there are many ways to solve it!
-
-- Solving ID conflict in a simple/local context:
-When passing a label you can optionally specify extra ID information within the string itself.
-Use "##" to pass a complement to the ID that won't be visible to the end-user.
-This helps solve the simple collision cases when you know e.g. at compilation time which items
-are going to be created:
-```cpp
-Begin("MyWindow");
-Button("Play"); // Label = "Play", ID = hash of ("MyWindow", "Play")
-Button("Play##foo1"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo1") // Different from other buttons
-Button("Play##foo2"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo2") // Different from other buttons
-Button("##foo"); // Label = "", ID = hash of ("MyWindow", "##foo") // Different from window
-End();
-```
-- If you want to completely hide the label, but still need an ID:
-```cpp
-Checkbox("##On", &b); // Label = "", ID = hash of (..., "##On") // No visible label, just a checkbox!
-```
-- Occasionally/rarely you might want to change a label while preserving a constant ID. This allows
-you to animate labels. For example, you may want to include varying information in a window title bar,
-but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID:
-```cpp
-Button("Hello###ID"); // Label = "Hello", ID = hash of (..., "###ID")
-Button("World###ID"); // Label = "World", ID = hash of (..., "###ID") // Same ID, different label
-
-sprintf(buf, "My game (%f FPS)###MyGame", fps);
-Begin(buf); // Variable title, ID = hash of "MyGame"
-```
-- Solving ID conflict in a more general manner:
-Use `PushID()` / `PopID()` to create scopes and manipulate the ID stack, as to avoid ID conflicts
-within the same window. This is the most convenient way of distinguishing ID when iterating and
-creating many UI elements programmatically.
-You can push a pointer, a string, or an integer value into the ID stack.
-Remember that IDs are formed from the concatenation of _everything_ pushed into the ID stack.
-At each level of the stack, we store the seed used for items at this level of the ID stack.
-```cpp
-Begin("Window");
-for (int i = 0; i < 100; i++)
-{
- PushID(i); // Push i to the id tack
- Button("Click"); // Label = "Click", ID = hash of ("Window", i, "Click")
- PopID();
-}
-for (int i = 0; i < 100; i++)
-{
- MyObject* obj = Objects[i];
- PushID(obj);
- Button("Click"); // Label = "Click", ID = hash of ("Window", obj pointer, "Click")
- PopID();
-}
-for (int i = 0; i < 100; i++)
-{
- MyObject* obj = Objects[i];
- PushID(obj->Name);
- Button("Click"); // Label = "Click", ID = hash of ("Window", obj->Name, "Click")
- PopID();
-}
-End();
-```
-- You can stack multiple prefixes into the ID stack:
-```cpp
-Button("Click"); // Label = "Click", ID = hash of (..., "Click")
-PushID("node");
- Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click")
- PushID(my_ptr);
- Button("Click"); // Label = "Click", ID = hash of (..., "node", my_ptr, "Click")
- PopID();
-PopID();
-```
-- Tree nodes implicitly create a scope for you by calling `PushID()`:
-```cpp
-Button("Click"); // Label = "Click", ID = hash of (..., "Click")
-if (TreeNode("node")) // <-- this function call will do a PushID() for you (unless instructed not to, with a special flag)
-{
- Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click")
- TreePop();
-}
-```
-
-When working with trees, IDs are used to preserve the open/close state of each tree node.
-Depending on your use cases you may want to use strings, indices, or pointers as ID.
-- e.g. when following a single pointer that may change over time, using a static string as ID
-will preserve your node open/closed state when the targeted object change.
-- e.g. when displaying a list of objects, using indices or pointers as ID will preserve the
-node open/closed state differently. See what makes more sense in your situation!

-### Q: How can I display an image? What is ImTextureID, how does it work?
-
-Short explanation:
-- Refer to [Image Loading and Displaying Examples](https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples) on the [Wiki](https://github.com/ocornut/imgui/wiki).
-- You may use functions such as `ImGui::Image()`, `ImGui::ImageButton()` or lower-level `ImDrawList::AddImage()` to emit draw calls that will use your own textures.
-- Actual textures are identified in a way that is up to the user/engine. Those identifiers are stored and passed as ImTextureID (void*) value.
-- Loading image files from the disk and turning them into a texture is not within the scope of Dear ImGui (for a good reason).
-
-**Please read documentations or tutorials on your graphics API to understand how to display textures on the screen before moving onward.**
-
-Long explanation:
-- Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. At the end of the frame, those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code to render them is generally fairly short (a few dozen lines). In the examples/ folder, we provide functions for popular graphics APIs (OpenGL, DirectX, etc.).
-- Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API.
- We carry the information to identify a "texture" in the ImTextureID type.
-ImTextureID is nothing more than a void*, aka 4/8 bytes worth of data: just enough to store one pointer or integer of your choice.
-Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely passes ImTextureID values until they reach your rendering function.
-- In the [examples/](https://github.com/ocornut/imgui/tree/master/examples) backends, for each graphics API we decided on a type that is likely to be a good representation for specifying an image from the end-user perspective. This is what the _examples_ rendering functions are using:
-```cpp
-OpenGL:
-- ImTextureID = GLuint
-- See ImGui_ImplOpenGL3_RenderDrawData() function in imgui_impl_opengl3.cpp
-```
-```cpp
-DirectX9:
-- ImTextureID = LPDIRECT3DTEXTURE9
-- See ImGui_ImplDX9_RenderDrawData() function in imgui_impl_dx9.cpp
-```
-```cpp
-DirectX11:
-- ImTextureID = ID3D11ShaderResourceView*
-- See ImGui_ImplDX11_RenderDrawData() function in imgui_impl_dx11.cpp
-```
-```cpp
-DirectX12:
-- ImTextureID = D3D12_GPU_DESCRIPTOR_HANDLE
-- See ImGui_ImplDX12_RenderDrawData() function in imgui_impl_dx12.cpp
-```
-For example, in the OpenGL example backend we store raw OpenGL texture identifier (GLuint) inside ImTextureID.
-Whereas in the DirectX11 example backend we store a pointer to ID3D11ShaderResourceView inside ImTextureID, which is a higher-level structure tying together both the texture and information about its format and how to read it.
-
-- If you have a custom engine built over e.g. OpenGL, instead of passing GLuint around you may decide to use a high-level data type to carry information about the texture as well as how to display it (shaders, etc.). The decision of what to use as ImTextureID can always be made better by knowing how your codebase is designed. If your engine has high-level data types for "textures" and "material" then you may want to use them.
-If you are starting with OpenGL or DirectX or Vulkan and haven't built much of a rendering engine over them, keeping the default ImTextureID representation suggested by the example backends is probably the best choice.
-(Advanced users may also decide to keep a low-level type in ImTextureID, use ImDrawList callback and pass information to their renderer)
-
-User code may do:
-```cpp
-// Cast our texture type to ImTextureID / void*
-MyTexture* texture = g_CoffeeTableTexture;
-ImGui::Image((void*)texture, ImVec2(texture->Width, texture->Height));
-```
-The renderer function called after ImGui::Render() will receive that same value that the user code passed:
-```cpp
-// Cast ImTextureID / void* stored in the draw command as our texture type
-MyTexture* texture = (MyTexture*)pcmd->GetTexID();
-MyEngineBindTexture2D(texture);
-```
-Once you understand this design, you will understand that loading image files and turning them into displayable textures is not within the scope of Dear ImGui.
-This is by design and is a good thing because it means your code has full control over your data types and how you display them.
-If you want to display an image file (e.g. PNG file) on the screen, please refer to documentation and tutorials for the graphics API you are using.
-
-Refer to [Image Loading and Displaying Examples](https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples) on the [Wiki](https://github.com/ocornut/imgui/wiki) to find simplified examples for loading textures with OpenGL, DirectX9 and DirectX11.
-
-C/C++ tip: a void* is pointer-sized storage. You may safely store any pointer or integer into it by casting your value to ImTextureID / void*, and vice-versa.
-Because both end-points (user code and rendering function) are under your control, you know exactly what is stored inside the ImTextureID / void*.
-Here are some examples:
-```cpp
-GLuint my_tex = XXX;
-void* my_void_ptr;
-my_void_ptr = (void*)(intptr_t)my_tex; // cast a GLuint into a void* (we don't take its address! we literally store the value inside the pointer)
-my_tex = (GLuint)(intptr_t)my_void_ptr; // cast a void* into a GLuint
-
-ID3D11ShaderResourceView* my_dx11_srv = XXX;
-void* my_void_ptr;
-my_void_ptr = (void*)my_dx11_srv; // cast a ID3D11ShaderResourceView* into an opaque void*
-my_dx11_srv = (ID3D11ShaderResourceView*)my_void_ptr; // cast a void* into a ID3D11ShaderResourceView*
-```
-Finally, you may call `ImGui::ShowMetricsWindow()` to explore/visualize/understand how the ImDrawList are generated.

-### Q: How can I use maths operators with ImVec2?
-
-We do not export maths operators by default in imgui.h in order to not conflict with the use of your own maths types and maths operators. As a convenience, you may use `#define IMGUI_DEFINE_MATH_OPERATORS` + `#include "imgui.h"` to access our basic maths operators.
-

-
-### Q: How can I use my own maths types instead of ImVec2/ImVec4?
-
-You can setup your [imconfig.h](https://github.com/ocornut/imgui/blob/master/imconfig.h) file with `IM_VEC2_CLASS_EXTRA`/`IM_VEC4_CLASS_EXTRA` macros to add implicit type conversions to our own maths types.
-This way you will be able to use your own types everywhere, e.g. passing `MyVector2` or `glm::vec2` to ImGui functions instead of `ImVec2`.

-### Q: How can I interact with standard C++ types (such as std::string and std::vector)?
-- Being highly portable (backends/bindings for several languages, frameworks, programming styles, obscure or older platforms/compilers), and aiming for compatibility & performance suitable for every modern real-time game engine, Dear ImGui does not use any of std C++ types. We use raw types (e.g. char* instead of std::string) because they adapt to more use cases.
-- To use ImGui::InputText() with a std::string or any resizable string class, see [misc/cpp/imgui_stdlib.h](https://github.com/ocornut/imgui/blob/master/misc/cpp/imgui_stdlib.h).
-- To use combo boxes and list boxes with `std::vector` or any other data structure: the `BeginCombo()/EndCombo()` API
-lets you iterate and submit items yourself, so does the `ListBoxHeader()/ListBoxFooter()` API.
-Prefer using them over the old and awkward `Combo()/ListBox()` api.
-- Generally for most high-level types you should be able to access the underlying data type.
-You may write your own one-liner wrappers to facilitate user code (tip: add new functions in ImGui:: namespace from your code).
-- Dear ImGui applications often need to make intensive use of strings. It is expected that many of the strings you will pass
-to the API are raw literals (free in C/C++) or allocated in a manner that won't incur a large cost on your application.
-Please bear in mind that using `std::string` on applications with a large amount of UI may incur unsatisfactory performances.
-Modern implementations of `std::string` often include small-string optimization (which is often a local buffer) but those
-are not configurable and not the same across implementations.
-- If you are finding your UI traversal cost to be too large, make sure your string usage is not leading to an excessive amount
-of heap allocations. Consider using literals, statically sized buffers, and your own helper functions. A common pattern
-is that you will need to build lots of strings on the fly, and their maximum length can be easily scoped ahead.
-One possible implementation of a helper to facilitate printf-style building of strings: https://github.com/ocornut/Str
-This is a small helper where you can instance strings with configurable local buffers length. Many game engines will
-provide similar or better string helpers.

-### Q: How can I display custom shapes? (using low-level ImDrawList API)
-
-- You can use the low-level `ImDrawList` api to render shapes within a window.
-```cpp
-ImGui::Begin("My shapes");
-
-ImDrawList* draw_list = ImGui::GetWindowDrawList();
-
-// Get the current ImGui cursor position
-ImVec2 p = ImGui::GetCursorScreenPos();
-
-// Draw a red circle
-draw_list->AddCircleFilled(ImVec2(p.x + 50, p.y + 50), 30.0f, IM_COL32(255, 0, 0, 255));
-
-// Draw a 3 pixel thick yellow line
-draw_list->AddLine(ImVec2(p.x, p.y), ImVec2(p.x + 100.0f, p.y + 100.0f), IM_COL32(255, 255, 0, 255), 3.0f);
-
-// Advance the ImGui cursor to claim space in the window (otherwise the window will appear small and needs to be resized)
-ImGui::Dummy(ImVec2(200, 200));
-
-ImGui::End();
-```
-
-
-- Refer to "Demo > Examples > Custom Rendering" in the demo window and read the code of `ShowExampleAppCustomRendering()` in `imgui_demo.cpp` from more examples.
-- To generate colors: you can use the macro `IM_COL32(255,255,255,255)` to generate them at compile time, or use `ImGui::GetColorU32(IM_COL32(255,255,255,255))` or `ImGui::GetColorU32(ImVec4(1.0f,1.0f,1.0f,1.0f))` to generate a color that is multiplied by the current value of `style.Alpha`.
-- Math operators: if you have setup `IM_VEC2_CLASS_EXTRA` in `imconfig.h` to bind your own math types, you can use your own math types and their natural operators instead of ImVec2. ImVec2 by default doesn't export any math operators in the public API. You may use `#define IMGUI_DEFINE_MATH_OPERATORS` `#include "imgui.h"` to use our math operators, but instead prefer using your own math library and set it up in `imconfig.h`.
-- You can use `ImGui::GetBackgroundDrawList()` or `ImGui::GetForegroundDrawList()` to access draw lists which will be displayed behind and over every other Dear ImGui window (one bg/fg drawlist per viewport). This is very convenient if you need to quickly display something on the screen that is not associated with a Dear ImGui window.
-- You can also create your own empty window and draw inside it. Call Begin() with the NoBackground | NoDecoration | NoSavedSettings | NoInputs flags (The `ImGuiWindowFlags_NoDecoration` flag itself is a shortcut for NoTitleBar | NoResize | NoScrollbar | NoCollapse). Then you can retrieve the ImDrawList* via `GetWindowDrawList()` and draw to it in any way you like.
-- You can create your own ImDrawList instance. You'll need to initialize them with `ImGui::GetDrawListSharedData()`, or create your own instancing `ImDrawListSharedData`, and then call your renderer function with your own ImDrawList or ImDrawData data.
-- Looking for fun? The [ImDrawList coding party 2020](https://github.com/ocornut/imgui/issues/3606) thread is full of "don't do this at home" extreme uses of the ImDrawList API.

-# Q&A: Fonts, Text
-
-### Q: How should I handle DPI in my application?
-
-The short answer is: obtain the desired DPI scale, load your fonts resized with that scale (always round down fonts size to the nearest integer), and scale your Style structure accordingly using `style.ScaleAllSizes()`.
-
-Your application may want to detect DPI change and reload the fonts and reset style between frames.
-
-Your ui code should avoid using hardcoded constants for size and positioning. Prefer to express values as multiple of reference values such as `ImGui::GetFontSize()` or `ImGui::GetFrameHeight()`. So e.g. instead of seeing a hardcoded height of 500 for a given item/window, you may want to use `30*ImGui::GetFontSize()` instead.
-
-Down the line Dear ImGui will provide a variety of standardized reference values to facilitate using this.
-
-Applications in the `examples/` folder are not DPI aware partly because they are unable to load a custom font from the file-system (may change that in the future).
-
-The reason DPI is not auto-magically solved in stock examples is that we don't yet have a satisfying solution for the "multi-dpi" problem (using the `docking` branch: when multiple viewport windows are over multiple monitors using different DPI scales). The current way to handle this on the application side is:
-- Create and maintain one font atlas per active DPI scale (e.g. by iterating `platform_io.Monitors[]` before `NewFrame()`).
-- Hook `platform_io.OnChangedViewport()` to detect when a `Begin()` call makes a Dear ImGui window change monitor (and therefore DPI).
-- In the hook: swap atlas, swap style with correctly sized one, and remap the current font from one atlas to the other (you may need to maintain a remapping table of your fonts at varying DPI scales).
-
-This approach is relatively easy and functional but comes with two issues:
-- It's not possibly to reliably size or position a window ahead of `Begin()` without knowing on which monitor it'll land.
-- Style override may be lost during the `Begin()` call crossing monitor boundaries. You may need to do some custom scaling mumbo-jumbo if you want your `OnChangedViewport()` handler to preserve style overrides.
-
-Please note that if you are not using multi-viewports with multi-monitors using different DPI scales, you can ignore that and use the simpler technique recommended at the top.
-
-On Windows, in addition to scaling the font size (make sure to round to an integer) and using `style.ScaleAllSizes()`, you will need to inform Windows that your application is DPI aware. If this is not done, Windows will scale the application window and the UI text will be blurry. Potential solutions to indicate DPI awareness on Windows are:
-
-- For SDL: the flag `SDL_WINDOW_ALLOW_HIGHDPI` needs to be passed to `SDL_CreateWindow()``.
-- For GLFW: this is done automatically.
-- For other Windows projects with other backends, or wrapper projects:
- - We provide a `ImGui_ImplWin32_EnableDpiAwareness()` helper method in the Win32 backend.
- - Use an [application manifest file](https://learn.microsoft.com/en-us/windows/win32/hidpi/setting-the-default-dpi-awareness-for-a-process) to set the `` property.
-
-### Q: How can I load a different font than the default?
-Use the font atlas to load the TTF/OTF file you want:
-
-```cpp
-ImGuiIO& io = ImGui::GetIO();
-io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
-io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
-```
-
-Default is ProggyClean.ttf, monospace, rendered at size 13, embedded in dear imgui's source code.
-
-(Tip: monospace fonts are convenient because they allow to facilitate horizontal alignment directly at the string level.)
-
-(Read the [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) file for more details about font loading.)
-
-New programmers: remember that in C/C++ and most programming languages if you want to use a
-backslash \ within a string literal, you need to write it double backslash "\\":
-
-```cpp
-io.Fonts->AddFontFromFileTTF("MyFolder\MyFont.ttf", size); // WRONG (you are escaping the M here!)
-io.Fonts->AddFontFromFileTTF("MyFolder\\MyFont.ttf", size); // CORRECT (Windows only)
-io.Fonts->AddFontFromFileTTF("MyFolder/MyFont.ttf", size); // ALSO CORRECT
-```

-### Q: How can I easily use icons in my application?
-The most convenient and practical way is to merge an icon font such as FontAwesome inside your
-main font. Then you can refer to icons within your strings.

-
-### Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
-When loading a font, pass custom Unicode ranges to specify the glyphs to load.
-
-```cpp
-// Add default Japanese ranges
-io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, nullptr, io.Fonts->GetGlyphRangesJapanese());
-
-// Or create your own custom ranges (e.g. for a game you can feed your entire game script and only build the characters the game need)
-ImVector ranges;
-ImFontGlyphRangesBuilder builder;
-builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
-builder.AddChar(0x7262); // Add a specific character
-builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
-builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
-io.Fonts->AddFontFromFileTTF("myfontfile.ttf", 16.0f, nullptr, ranges.Data);
-```
-
-All your strings need to use UTF-8 encoding.
-You need to tell your compiler to use UTF-8, or in C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax.
-Specifying literal in your source code using a local code page (such as CP-923 for Japanese or CP-1251 for Cyrillic) will NOT work!
-See [About UTF-8 Encoding](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md#about-utf-8-encoding) section
-of [FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) for details about UTF-8 Encoding.
-
-Text input: it is up to your application to pass the right character code by calling `io.AddInputCharacter()`.
-The applications in examples/ are doing that.
-Windows: you can use the WM_CHAR or WM_UNICHAR or WM_IME_CHAR message (depending if your app is built using Unicode or MultiByte mode).
-You may also use `MultiByteToWideChar()` or `ToUnicode()` to retrieve Unicode codepoints from MultiByte characters or keyboard state.
-Windows: if your language is relying on an Input Method Editor (IME), you can write your HWND to ImGui::GetMainViewport()->PlatformHandleRaw
-for the default implementation of io.SetPlatformImeDataFn() to set your Microsoft IME position correctly.

-### Q: Can you create elaborate/serious tools with Dear ImGui?
-
-Yes. People have written game editors, data browsers, debuggers, profilers, and all sorts of non-trivial tools with the library. In my experience, the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library.
-
-Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might require you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient, and powerful.
-
-Dear ImGui is built to be efficient and scalable toward the needs for AAA-quality applications running all day. The IMGUI paradigm offers different opportunities for optimization than the more typical RMGUI paradigm.

-### Q: Can you reskin the look of Dear ImGui?
-
-Somewhat. You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, and fonts. However, as Dear ImGui is designed and optimized to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Dear ImGui is NOT designed to create a user interface for games, although with ingenious use of the low-level API you can do it.
-
-A reasonably skinned application may look like (screenshot from [#2529](https://github.com/ocornut/imgui/issues/2529#issuecomment-524281119)):

-### Q: Why using C++ (as opposed to C)?
-
-Dear ImGui takes advantage of a few C++ language features for convenience but nothing anywhere Boost insanity/quagmire. Dear ImGui doesn't use any C++ header file. Dear ImGui uses a very small subset of C++11 features. In particular, function overloading and default parameters are used to make the API easier to use and code terser. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors, and templates (in the case of the ImVector<> class) are also relied on as a convenience.
-
-There is an auto-generated [c-api for Dear ImGui (cimgui)](https://github.com/cimgui/cimgui) by Sonoro1234 and Stephan Dilly. It is designed for creating bindings to other languages. If possible, I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for various third-party bindings.

-## Dear ImGui: Using Fonts
-
-The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' (by Tristan Grimmer),
-a 13 pixels high, pixel-perfect font used by default. We embed it in the source code so you can use Dear ImGui without any file system access. ProggyClean does not scale smoothly, therefore it is recommended that you load your own file when using Dear ImGui in an application aiming to look nice and wanting to support multiple resolutions.
-
-You may also load external .TTF/.OTF files.
-In the [misc/fonts/](https://github.com/ocornut/imgui/tree/master/misc/fonts) folder you can find a few suggested fonts, provided as a convenience.
-
-**Also read the FAQ:** https://www.dearimgui.com/faq (there is a Fonts section!)

-## Troubleshooting
-
-**A vast majority of font and text related issues encountered comes from 4 things:**
-
-### (1) Invalid filename due to use of `\` or unexpected working directory.
-
-See [About Filenames](#about-filenames). AddFontXXX functions should assert if the filename is incorrect.
-
-### (2) Invalid UTF-8 encoding of your non-ASCII strings.
-
-See [About UTF-8 Encoding](#about-utf-8-encoding). Use the encoding viewer to confirm encoding of string literal in your source code is correct.
-
-### (3) Missing glyph ranges.
-
-You need to load a font with explicit glyph ranges if you want to use non-ASCII characters. See [Fonts Loading Instructions](#fonts-loading-instructions). Use [Debug Tools](#debug-tools) confirm loaded fonts and loaded glyph ranges.
-
-This is a current constraint of Dear ImGui (which we will lift in the future): when loading a font you need to specify which characters glyphs to load.
-All loaded fonts glyphs are rendered into a single texture atlas ahead of time. Calling either of `io.Fonts->GetTexDataAsAlpha8()`, `io.Fonts->GetTexDataAsRGBA32()` or `io.Fonts->Build()` will build the atlas. This is generally called by the Renderer backend, e.g. `ImGui_ImplDX11_NewFrame()` calls it. **If you use custom glyphs ranges, make sure the array is persistent** and available during the calls to `GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build()`.
-
-### (4) Font atlas texture fails to upload to GPU.
-
-This is often of byproduct of point 3. If you have large number of glyphs or multiple fonts, the texture may become too big for your graphics API. **The typical result of failing to upload a texture is if every glyph or everything appears as empty black or white rectangle.** Mind the fact that some graphics drivers have texture size limitation. If you are building a PC application, mind the fact that your users may use hardware with lower limitations than yours.
-
-Some solutions:
-- You may reduce oversampling, e.g. `font_config.OversampleH = 1`, this will half your texture size for a quality looss.
- Note that while OversampleH = 2 looks visibly very close to 3 in most situations, with OversampleH = 1 the quality drop will be noticeable. Read about oversampling [here](https://github.com/nothings/stb/blob/master/tests/oversample).
-- Reduce glyphs ranges by calculating them from source localization data.
- You can use the `ImFontGlyphRangesBuilder` for this purpose and rebuilding your atlas between frames when new characters are needed. This will be the biggest win!
-- Set `io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight;` to disable rounding the texture height to the next power of two.
-- Set `io.Fonts.TexDesiredWidth` to specify a texture width to reduce maximum texture height (see comment in `ImFontAtlas::Build()` function).

-## Fonts Loading Instructions
-
-**Load default font:**
-```cpp
-ImGuiIO& io = ImGui::GetIO();
-io.Fonts->AddFontDefault();
-```
-
-**Load .TTF/.OTF file with:**
-```cpp
-ImGuiIO& io = ImGui::GetIO();
-io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
-```
-If you get an assert stating "Could not load font file!", your font filename is likely incorrect. Read [About filenames](#about-filenames) carefully.
-
-**Load multiple fonts:**
-```cpp
-// Init
-ImGuiIO& io = ImGui::GetIO();
-ImFont* font1 = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
-ImFont* font2 = io.Fonts->AddFontFromFileTTF("anotherfont.otf", size_pixels);
-```
-
-In your application loop, select which font to use:
-```cpp
-ImGui::Text("Hello"); // use the default font (which is the first loaded font)
-ImGui::PushFont(font2);
-ImGui::Text("Hello with another font");
-ImGui::PopFont();
-```
-
-**For advanced options create a ImFontConfig structure and pass it to the AddFont() function (it will be copied internally):**
-```cpp
-ImFontConfig config;
-config.OversampleH = 2;
-config.OversampleV = 1;
-config.GlyphExtraSpacing.x = 1.0f;
-ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config);
-```
-
-**Combine multiple fonts into one:**
-```cpp
-// Load a first font
-ImFont* font = io.Fonts->AddFontDefault();
-
-// Add character ranges and merge into the previous font
-// The ranges array is not copied by the AddFont* functions and is used lazily
-// so ensure it is available at the time of building or calling GetTexDataAsRGBA32().
-static const ImWchar icons_ranges[] = { 0xf000, 0xf3ff, 0 }; // Will not be copied by AddFont* so keep in scope.
-ImFontConfig config;
-config.MergeMode = true;
-io.Fonts->AddFontFromFileTTF("DroidSans.ttf", 18.0f, &config, io.Fonts->GetGlyphRangesJapanese()); // Merge into first font
-io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 18.0f, &config, icons_ranges); // Merge into first font
-io.Fonts->Build();
-```
-
-**Add a fourth parameter to bake specific font ranges only:**
-
-```cpp
-// Basic Latin, Extended Latin
-io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, nullptr, io.Fonts->GetGlyphRangesDefault());
-
-// Default + Selection of 2500 Ideographs used by Simplified Chinese
-io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, nullptr, io.Fonts->GetGlyphRangesChineseSimplifiedCommon());
-
-// Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
-io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, nullptr, io.Fonts->GetGlyphRangesJapanese());
-```
-See [Using Custom Glyph Ranges](#using-custom-glyph-ranges) section to create your own ranges.
-
-**Example loading and using a Japanese font:**
-
-```cpp
-ImGuiIO& io = ImGui::GetIO();
-io.Fonts->AddFontFromFileTTF("NotoSansCJKjp-Medium.otf", 20.0f, nullptr, io.Fonts->GetGlyphRangesJapanese());
-```
-```cpp
-ImGui::Text(u8"こんにちは！テスト %d", 123);
-if (ImGui::Button(u8"ロード"))
-{
- // do stuff
-}
-ImGui::InputText("string", buf, IM_ARRAYSIZE(buf));
-ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
-```
-
-
- _(settings: Dark style (left), Light style (right) / Font: NotoSansCJKjp-Medium, 20px / Rounding: 5)_

-## Loading Font Data from Memory
-
-```cpp
-ImFont* font = io.Fonts->AddFontFromMemoryTTF(data, data_size, size_pixels, ...);
-```
-
-IMPORTANT: `AddFontFromMemoryTTF()` by default transfer ownership of the data buffer to the font atlas, which will attempt to free it on destruction.
-This was to avoid an unnecessary copy, and is perhaps not a good API (a future version will redesign it).
-If you want to keep ownership of the data and free it yourself, you need to clear the `FontDataOwnedByAtlas` field:
-
-```cpp
-ImFontConfig font_cfg;
-font_cfg.FontDataOwnedByAtlas = false;
-ImFont* font = io.Fonts->AddFontFromMemoryTTF(data, data_size, size_pixels, &font_cfg);
-```

-## Loading Font Data Embedded In Source Code
-
-- Compile and use [binary_to_compressed_c.cpp](https://github.com/ocornut/imgui/blob/master/misc/fonts/binary_to_compressed_c.cpp) to create a compressed C style array that you can embed in source code.
-- See the documentation in [binary_to_compressed_c.cpp](https://github.com/ocornut/imgui/blob/master/misc/fonts/binary_to_compressed_c.cpp) for instructions on how to use the tool.
-- You may find a precompiled version binary_to_compressed_c.exe for Windows inside the demo binaries package (see [README](https://github.com/ocornut/imgui/blob/master/docs/README.md)).
-- The tool can optionally output Base85 encoding to reduce the size of _source code_ but the read-only arrays in the actual binary will be about 20% bigger.
-
-Then load the font with:
-```cpp
-ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...);
-```
-or
-```cpp
-ImFont* font = io.Fonts->AddFontFromMemoryCompressedBase85TTF(compressed_data_base85, size_pixels, ...);
-```

-## Using Icon Fonts
-
-Using an icon font (such as [FontAwesome](http://fontawesome.io) or [OpenFontIcons](https://github.com/traverseda/OpenFontIcons)) is an easy and practical way to use icons in your Dear ImGui application.
-A common pattern is to merge the icon font within your main font, so you can embed icons directly from your strings without having to change fonts back and forth.
-
-To refer to the icon UTF-8 codepoints from your C++ code, you may use those headers files created by Juliette Foucaut: https://github.com/juliettef/IconFontCppHeaders.
-
-So you can use `ICON_FA_SEARCH` as a string that will render as a "Search" icon.
-
-Example Setup:
-```cpp
-// Merge icons into default tool font
-#include "IconsFontAwesome.h"
-ImGuiIO& io = ImGui::GetIO();
-io.Fonts->AddFontDefault();
-
-ImFontConfig config;
-config.MergeMode = true;
-config.GlyphMinAdvanceX = 13.0f; // Use if you want to make the icon monospaced
-static const ImWchar icon_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 };
-io.Fonts->AddFontFromFileTTF("fonts/fontawesome-webfont.ttf", 13.0f, &config, icon_ranges);
-```
-Example Usage:
-```cpp
-// Usage, e.g.
-ImGui::Text("%s among %d items", ICON_FA_SEARCH, count);
-ImGui::Button(ICON_FA_SEARCH " Search");
-// C string _literals_ can be concatenated at compilation time, e.g. "hello" " world"
-// ICON_FA_SEARCH is defined as a string literal so this is the same as "A" "B" becoming "AB"
-```
-See Links below for other icons fonts and related tools.
-
-**Monospace Icons?**
-
-To make your icon look more monospace and facilitate alignment, you may want to set the ImFontConfig::GlyphMinAdvanceX value when loading an icon font.
-

-## Using FreeType Rasterizer (imgui_freetype)
-
-- Dear ImGui uses imstb\_truetype.h to rasterize fonts (with optional oversampling). This technique and its implementation are not ideal for fonts rendered at small sizes, which may appear a little blurry or hard to read.
-- There is an implementation of the ImFontAtlas builder using FreeType that you can use in the [misc/freetype/](https://github.com/ocornut/imgui/tree/master/misc/freetype) folder.
-- FreeType supports auto-hinting which tends to improve the readability of small fonts.
-- Read documentation in the [misc/freetype/](https://github.com/ocornut/imgui/tree/master/misc/freetype) folder.
-- Correct sRGB space blending will have an important effect on your font rendering quality.
-

-
----------------------------------------
-
-## Using Colorful Glyphs/Emojis
-
-- Rendering of colored emojis is supported by imgui_freetype with FreeType 2.10+.
-- You will need to load fonts with the `ImGuiFreeTypeBuilderFlags_LoadColor` flag.
-- Emojis are frequently encoded in upper Unicode layers (character codes >0x10000) and will need dear imgui compiled with `IMGUI_USE_WCHAR32`.
-- Not all types of color fonts are supported by FreeType at the moment.
-- Stateful Unicode features such as skin tone modifiers are not supported by the text renderer.
-
-
-
-```cpp
-io.Fonts->AddFontFromFileTTF("../../../imgui_dev/data/fonts/NotoSans-Regular.ttf", 16.0f);
-static ImWchar ranges[] = { 0x1, 0x1FFFF, 0 };
-static ImFontConfig cfg;
-cfg.OversampleH = cfg.OversampleV = 1;
-cfg.MergeMode = true;
-cfg.FontBuilderFlags |= ImGuiFreeTypeBuilderFlags_LoadColor;
-io.Fonts->AddFontFromFileTTF("C:\\Windows\\Fonts\\seguiemj.ttf", 16.0f, &cfg, ranges);
-```
-

-
----------------------------------------
-
-## Using Custom Glyph Ranges
-
-You can use the `ImFontGlyphRangesBuilder` helper to create glyph ranges based on text input. For example: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.
-```cpp
-ImVector ranges;
-ImFontGlyphRangesBuilder builder;
-builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
-builder.AddChar(0x7262); // Add a specific character
-builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
-builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
-
-io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, nullptr, ranges.Data);
-io.Fonts->Build(); // Build the atlas while 'ranges' is still in scope and not deleted.
-```
-

-
----------------------------------------
-
-## Using Custom Colorful Icons
-
-As an alternative to rendering colorful glyphs using imgui_freetype with `ImGuiFreeTypeBuilderFlags_LoadColor`, you may allocate your own space in the texture atlas and write yourself into it. **(This is a BETA api, use if you are familiar with dear imgui and with your rendering backend)**
-
-- You can use the `ImFontAtlas::AddCustomRect()` and `ImFontAtlas::AddCustomRectFontGlyph()` api to register rectangles that will be packed into the font atlas texture. Register them before building the atlas, then call Build()`.
-- You can then use `ImFontAtlas::GetCustomRectByIndex(int)` to query the position/size of your rectangle within the texture, and blit/copy any graphics data of your choice into those rectangles.
-- This API is beta because it is likely to change in order to support multi-dpi (multiple viewports on multiple monitors with varying DPI scale).
-
-#### Pseudo-code:
-```cpp
-// Add font, then register two custom 13x13 rectangles mapped to glyph 'a' and 'b' of this font
-ImFont* font = io.Fonts->AddFontDefault();
-int rect_ids[2];
-rect_ids[0] = io.Fonts->AddCustomRectFontGlyph(font, 'a', 13, 13, 13+1);
-rect_ids[1] = io.Fonts->AddCustomRectFontGlyph(font, 'b', 13, 13, 13+1);
-
-// Build atlas
-io.Fonts->Build();
-
-// Retrieve texture in RGBA format
-unsigned char* tex_pixels = nullptr;
-int tex_width, tex_height;
-io.Fonts->GetTexDataAsRGBA32(&tex_pixels, &tex_width, &tex_height);
-
-for (int rect_n = 0; rect_n < IM_ARRAYSIZE(rect_ids); rect_n++)
-{
- int rect_id = rect_ids[rect_n];
- if (const ImFontAtlasCustomRect* rect = io.Fonts->GetCustomRectByIndex(rect_id))
- {
- // Fill the custom rectangle with red pixels (in reality you would draw/copy your bitmap data here!)
- for (int y = 0; y < rect->Height; y++)
- {
- ImU32* p = (ImU32*)tex_pixels + (rect->Y + y) * tex_width + (rect->X);
- for (int x = rect->Width; x > 0; x--)
- *p++ = IM_COL32(255, 0, 0, 255);
- }
- }
-}

-## About Filenames
-
-**Please note that many new C/C++ users have issues loading their files _because the filename they provide is wrong_ due to incorrect assumption of what is the current directory.**
-
-Two things to watch for:
-
-(1) In C/C++ and most programming languages if you want to use a backslash `\` within a string literal, you need to write it double backslash `\\`. At it happens, Windows uses backslashes as a path separator, so be mindful.
-```cpp
-io.Fonts->AddFontFromFileTTF("MyFiles\MyImage01.jpg", ...); // This is INCORRECT!!
-io.Fonts->AddFontFromFileTTF("MyFiles\\MyImage01.jpg", ...); // This is CORRECT
-```
-In some situations, you may also use `/` path separator under Windows.
-
-(2) Make sure your IDE/debugger settings starts your executable from the right working (current) directory. In Visual Studio you can change your working directory in project `Properties > General > Debugging > Working Directory`. People assume that their execution will start from the root folder of the project, where by default it often starts from the folder where object or executable files are stored.
-```cpp
-io.Fonts->AddFontFromFileTTF("MyImage01.jpg", ...); // Relative filename depends on your Working Directory when running your program!
-io.Fonts->AddFontFromFileTTF("../MyImage01.jpg", ...); // Load from the parent folder of your Working Directory
-```

-## About UTF-8 Encoding
-
-**For non-ASCII characters display, a common user issue is not passing correctly UTF-8 encoded strings.**
-
-(1) We provide a function `ImGui::DebugTextEncoding(const char* text)` which you can call to verify the content of your UTF-8 strings.
-This is a convenient way to confirm that your encoding is correct.
-
-```cpp
-ImGui::SeparatorText("CORRECT");
-ImGui::DebugTextEncoding(u8"こんにちは");
-
-ImGui::SeparatorText("INCORRECT");
-ImGui::DebugTextEncoding("こんにちは");
-```
-
-
-You can also find this tool under `Metrics/Debuggers->Tools->UTF-8 Encoding viewer` if you want to paste from clipboard, but this won't validate the UTF-8 encoding done by your compiler.
-
-(2) To encode in UTF-8:
-
-There are also compiler-specific ways to enforce UTF-8 encoding by default:
-
-- Visual Studio compiler: `/utf-8` command-line flag.
-- Visual Studio compiler: `#pragma execution_character_set("utf-8")` inside your code.
-- Since May 2023 we have changed the Visual Studio projects of all our examples to use `/utf-8` ([see commit](https://github.com/ocornut/imgui/commit/513af1efc9080857bbd10000d98f98f2a0c96803)).
-
-Or, since C++11, you can use the `u8"my text"` syntax to encode literal strings as UTF-8. e.g.:
-```cpp
-ImGui::Text(u8"hello");
-ImGui::Text(u8"こんにちは"); // this will always be encoded as UTF-8
-ImGui::Text("こんにちは"); // the encoding of this is depending on compiler settings/flags and may be incorrect.
-```
-
-Since C++20, because the C++ committee hate its users, they decided to change the `u8""` syntax to not return `const char*` but a new type `const char8_t*` which doesn't cast to `const char*`.
-Because of type usage of `u8""` in C++20 is a little more tedious:
-```cpp
-ImGui::Text((const char*)u8"こんにちは");
-```
-However, you can disable this behavior completely using the compiler option [`/Zc:char8_t-`](https://learn.microsoft.com/en-us/cpp/build/reference/zc-char8-t?view=msvc-170) for MSVC and [`-fno-char8_t`](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1423r3.html) for Clang and GCC.

-## Debug Tools
-
-#### Metrics/Debugger->Fonts
-You can use the `Metrics/Debugger` window (available in `Demo>Tools`) to browse your fonts and understand what's going on if you have an issue. You can also reach it in `Demo->Tools->Style Editor->Fonts`. The same information are also available in the Style Editor under Fonts.
-
-
-
-#### UTF-8 Encoding Viewer**
-You can use the `UTF-8 Encoding viewer` in `Metrics/Debugger` to verify the content of your UTF-8 strings. From C/C++ code, you can call `ImGui::DebugTextEncoding("my string");` function to verify that your UTF-8 encoding is correct.

-
-### The Pitch
-
-Dear ImGui is a **bloat-free graphical user interface library for C++**. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline-enabled application. It is fast, portable, renderer agnostic, and self-contained (no external dependencies).
-
-Dear ImGui is designed to **enable fast iterations** and to **empower programmers** to create **content creation tools and visualization / debug tools** (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal and lacks certain features commonly found in more high-level libraries.
-
-Dear ImGui is particularly suited to integration in game engines (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on console platforms where operating system features are non-standard.
-
- - Minimize state synchronization.
- - Minimize UI-related state storage on user side.
- - Minimize setup and maintenance.
- - Easy to use to create dynamic UI which are the reflection of a dynamic data set.
- - Easy to use to create code-driven and data-driven tools.
- - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools.
- - Easy to hack and improve.
- - Portable, minimize dependencies, run on target (consoles, phones, etc.).
- - Efficient runtime and memory consumption.
- - Battle-tested, used by [many major actors in the game industry](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui).
-
-### Usage
-
-**The core of Dear ImGui is self-contained within a few platform-agnostic files** which you can easily compile in your application/engine. They are all the files in the root folder of the repository (imgui*.cpp, imgui*.h). **No specific build process is required**. You can add the .cpp files into your existing project.
-
-**Backends for a variety of graphics API and rendering platforms** are provided in the [backends/](https://github.com/ocornut/imgui/tree/master/backends) folder, along with example applications in the [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder. You may also create your own backend. Anywhere where you can render textured triangles, you can render Dear ImGui.
-
-See the [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) guide and [Integration](#integration) section of this document for more details.
-
-After Dear ImGui is set up in your application, you can use it from \_anywhere\_ in your program loop:
-```cpp
-ImGui::Text("Hello, world %d", 123);
-if (ImGui::Button("Save"))
- MySaveFunction();
-ImGui::InputText("string", buf, IM_ARRAYSIZE(buf));
-ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
-```
-
-
-
-```cpp
-// Create a window called "My First Tool", with a menu bar.
-ImGui::Begin("My First Tool", &my_tool_active, ImGuiWindowFlags_MenuBar);
-if (ImGui::BeginMenuBar())
-{
- if (ImGui::BeginMenu("File"))
- {
- if (ImGui::MenuItem("Open..", "Ctrl+O")) { /* Do stuff */ }
- if (ImGui::MenuItem("Save", "Ctrl+S")) { /* Do stuff */ }
- if (ImGui::MenuItem("Close", "Ctrl+W")) { my_tool_active = false; }
- ImGui::EndMenu();
- }
- ImGui::EndMenuBar();
-}
-
-// Edit a color stored as 4 floats
-ImGui::ColorEdit4("Color", my_color);
-
-// Generate samples and plot them
-float samples[100];
-for (int n = 0; n < 100; n++)
- samples[n] = sinf(n * 0.2f + ImGui::GetTime() * 1.5f);
-ImGui::PlotLines("Samples", samples, 100);
-
-// Display contents in a scrolling region
-ImGui::TextColored(ImVec4(1,1,0,1), "Important Stuff");
-ImGui::BeginChild("Scrolling");
-for (int n = 0; n < 50; n++)
- ImGui::Text("%04d: Some text", n);
-ImGui::EndChild();
-ImGui::End();
-```
-
-
-Dear ImGui allows you to **create elaborate tools** as well as very short-lived ones. On the extreme side of short-livedness: using the Edit&Continue (hot code reload) feature of modern compilers you can add a few widgets to tweak variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game-making editor/framework, etc.
-
-### How it works
-
-The IMGUI paradigm through its API tries to minimize superfluous state duplication, state synchronization, and state retention from the user's point of view. It is less error-prone (less code and fewer bugs) than traditional retained-mode interfaces, and lends itself to creating dynamic user interfaces. Check out the Wiki's [About the IMGUI paradigm](https://github.com/ocornut/imgui/wiki#about-the-imgui-paradigm) section for more details.
-
-Dear ImGui outputs vertex buffers and command lists that you can easily render in your application. The number of draw calls and state changes required to render them is fairly small. Because Dear ImGui doesn't know or touch graphics state directly, you can call its functions anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate Dear ImGui with your existing codebase.
-
-_A common misunderstanding is to mistake immediate mode GUI for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the GUI functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._
-
-### Releases & Changelogs
-
-See [Releases](https://github.com/ocornut/imgui/releases) page for decorated Changelogs.
-Reading the changelogs is a good way to keep up to date with the things Dear ImGui has to offer, and maybe will give you ideas of some features that you've been ignoring until now!
-
-### Demo
-
-Calling the `ImGui::ShowDemoWindow()` function will create a demo window showcasing a variety of features and examples. The code is always available for reference in `imgui_demo.cpp`. [Here's how the demo looks](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v167/v167-misc.png).
-
-You should be able to build the examples from sources. If you don't, let us know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here:
-- [imgui-demo-binaries-20240105.zip](https://www.dearimgui.com/binaries/imgui-demo-binaries-20240105.zip) (Windows, 1.90.1 WIP, built 2024/01/05, master) or [older binaries](https://www.dearimgui.com/binaries).
-
-The demo applications are not DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at a different scale and scale your style with `style.ScaleAllSizes()` (see [FAQ](https://www.dearimgui.com/faq)).
-
-### Integration
-
-See the [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) guide for details.
-
-On most platforms and when using C++, **you should be able to use a combination of the [imgui_impl_xxxx](https://github.com/ocornut/imgui/tree/master/backends) backends without modification** (e.g. `imgui_impl_win32.cpp` + `imgui_impl_dx11.cpp`). If your engine supports multiple platforms, consider using more imgui_impl_xxxx files instead of rewriting them: this will be less work for you, and you can get Dear ImGui running immediately. You can _later_ decide to rewrite a custom backend using your custom engine functions if you wish so.
-
-Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading a texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles, which is essentially what Backends are doing. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that: setting up a window and using backends. If you follow the [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) guide it should in theory takes you less than an hour to integrate Dear ImGui. **Make sure to spend time reading the [FAQ](https://www.dearimgui.com/faq), comments, and the examples applications!**

-**Which version should I get?**
-
-We occasionally tag [Releases](https://github.com/ocornut/imgui/releases) (with nice releases notes) but it is generally safe and recommended to sync to latest `master` or `docking` branch. The library is fairly stable and regressions tend to be fixed fast when reported. Advanced users may want to use the `docking` branch with [Multi-Viewport](https://github.com/ocornut/imgui/issues/1542) and [Docking](https://github.com/ocornut/imgui/issues/2109) features. This branch is kept in sync with master regularly.

-
-Developed by [Omar Cornut](https://www.miracleworld.net) and every direct or indirect [contributors](https://github.com/ocornut/imgui/graphs/contributors) to the GitHub. The early version of this library was developed with the support of [Media Molecule](https://www.mediamolecule.com) and first used internally on the game [Tearaway](https://tearaway.mediamolecule.com) (PS Vita).
-
-Recurring contributors include Rokas Kupstys [@rokups](https://github.com/rokups) (2020-2022): a good portion of work on automation system and regression tests now available in [Dear ImGui Test Engine](https://github.com/ocornut/imgui_test_engine).
-
-Sponsoring, maintenance/support contracts and other B2B transactions are hosted and handled by [Disco Hello](https://www.discohello.com).
-
-Omar: "I first discovered the IMGUI paradigm at [Q-Games](https://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."

-ISSUES & TODO LIST
-
-Issue numbers (#) refer to GitHub issues listed at https://github.com/ocornut/imgui/issues/XXXX
-THIS LIST IS NOT WELL MAINTAINED. MOST OF THE WORK HAPPENS ON GITHUB NOWADAYS.
-The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point they usually exist on the github issue tracker).
-It's mostly a bunch of personal notes, probably incomplete. Feel free to query if you have any questions.
-
- - doc: add a proper documentation system (maybe relying on automation? #435)
- - doc: checklist app to verify backends/integration of imgui (test inputs, rendering, callback, etc.).
- - doc/tips: tips of the day: website? applet in imgui_club?
- - doc/wiki: work on the wiki https://github.com/ocornut/imgui/wiki
-
- - window: preserve/restore relative focus ordering (persistent or not), and e.g. of multiple reappearing windows (#2304) -> also see docking reference to same #.
- - window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis). (#690)
- - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
- - window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify.
- - window: begin with *p_open == false could return false.
- - window: get size/pos helpers given names (see discussion in #249)
- - window: when window is very small, prioritize resize button over close button.
- - window: double-clicking on title bar to minimize isn't consistent interaction, perhaps move to single-click on left-most collapse icon?
- - window: expose contents size. (#1045)
- - window: using SetWindowPos() inside Begin() and moving the window with the mouse reacts a very ugly glitch. We should just defer the SetWindowPos() call.
- - window: GetWindowSize() returns (0,0) when not calculated? (#1045)
- - window: investigate better auto-positioning for new windows.
- - window: top most window flag? more z-order contrl? (#2574)
- - window/size: manually triggered auto-fit (double-click on grip) shouldn't resize window down to viewport size?
- - window/size: how to allow to e.g. auto-size vertically to fit contents, but be horizontally resizable? Assuming SetNextWindowSize() is modified to treat -1.0f on each axis as "keep as-is" (would be good but might break erroneous code): Problem is UpdateWindowManualResize() and lots of code treat (window->AutoFitFramesX > 0 || window->AutoFitFramesY > 0) together.
- - window/opt: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate. -> this may require enforcing that it is illegal to submit contents if Begin returns false.
- - window/child: background options for child windows, border option (disable rounding).
- - window/child: allow resizing of child windows (possibly given min/max for each axis?.)
- - window/child: allow SetNextWindowContentSize() to work on child windows.
- - window/clipping: some form of clipping when DisplaySize (or corresponding viewport) is zero.
- - window/tabbing: add a way to signify that a window or docked window requires attention (e.g. blinking title bar, trying to click behind a modal).
- - window/id_stack: add e.g. window->GetIDFromPath() with support for leading / and ../ (#1390, #331) -> model from test engine.
- ! scrolling: exposing horizontal scrolling with Shift+Wheel even when scrollbar is disabled expose lots of issues (#2424, #1463)
- - scrolling: while holding down a scrollbar, try to keep the same contents visible (at least while not moving mouse)
- - scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
- - scrolling: forward mouse wheel scrolling to parent window when at the edge of scrolling limits? (useful for listbox,tables?)
- - scrolling/style: shadows on scrollable areas to denote that there is more contents (see e.g. DaVinci Resolve ui)
-
- - drawdata: make it easy to deep-copy (or swap?) a full ImDrawData so user can easily save that data if they use threaded rendering. (e.g. #2646)
- ! drawlist: add CalcTextSize() func to facilitate consistent code from user pov (currently need to use ImGui or ImFont alternatives!)
- - drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command). (WIP branch)
- - drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally
- - drawlist: non-AA strokes have gaps between points (#593, #288), glitch especially on RenderCheckmark() and ColorPicker4().
- - drawlist: callback: add an extra void* in ImDrawCallback to allow passing render-local data to the callback (would break API).
- - drawlist: AddRect vs AddLine position confusing (#2441)
- - drawlist/opt: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding. (#1962)
- - drawlist/opt: AddRect() axis aligned pixel aligned (no-aa) could use 8 triangles instead of 16 and no normal calculation.
- - drawlist/opt: thick AA line could be doable in same number of triangles as 1.0 AA line by storing gradient+full color in atlas.
-
- - items: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
-
- - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. (#395)
- - widgets: clean up widgets internal toward exposing everything and stabilizing imgui_internals.h.
- - widgets: add always-allow-overlap mode. This should perhaps be the default? one problem is that highlight after mouse-wheel scrolling gets deferred, makes scrolling more flickery.
- - widgets: start exposing PushItemFlag() and ImGuiItemFlags
- - widgets: alignment options in style (e.g. center Selectable, Right-Align within Button, etc.) #1260
- - widgets: activate by identifier (trigger button, focus given id)
- - widgets: custom glyph/shapes replacements for stock sapes. (also #6090 #2431 #2235 #6517)
- - widgets: coloredit: keep reporting as active when picker is on?
- - widgets: group/scalarn functions: expose more per-component information. e.g. store NextItemData.ComponentIdx set by scalarn function, groups can expose them back somehow.
- - selectable: using (size.x == 0.0f) and (SelectableTextAlign.x > 0.0f) followed by SameLine() is currently not supported.
- - selectable: generic BeginSelectable()/EndSelectable() mechanism. (work out alongside range-select branch)
- - selectable: a way to visualize partial/mixed selection (e.g. parent tree node has children with mixed selection)
-
- - input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile. (WIP branch)
- - input text: preserve scrolling when unfocused?
- - input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
- - input text: expose CursorPos in char filter event (#816)
- - input text: try usage idiom of using InputText with data only exposed through get/set accessors, without extraneous copy/alloc. (#3009)
- - input text: access public fields via a non-callback API e.g. InputTextGetState("xxx") that may return nullptr if not active (available in internals)
- - input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701)
- - input text: hover tooltip could show unclamped text
- - input text: support for INSERT key to toggle overwrite mode. currently disabled because stb_textedit behavior is unsatisfactory on multi-line. (#2863)
- - input text: option to Tab after an Enter validation.
- - input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
- - input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text.
- - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725)
- - input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependent). actually a very old bug but no one appears to have noticed it.
- - input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position.
- - input text: decorrelate display layout from inputs with custom template - e.g. what's the easiest way to implement a nice IP/Mac address input editor?
- - input text: global callback system so user can plug in an expression evaluator easily. (#1691)
- - input text: force scroll to end or scroll to a given line/contents (so user can implement a log or a search feature)
- - input text: a way to preview completion (e.g. disabled text completing from the cursor)
- - input text: a side bar that could e.g. preview where errors are. probably left to the user to draw but we'd need to give them the info there.
- - input text: a way for the user to provide syntax coloring.
- - input text: Shift+TAB with ImGuiInputTextFlags_AllowTabInput could eat preceding blanks, up to tab_count.
- - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
- - input text multi-line: support for copy/cut without selection (copy/cut current line?)
- - input text multi-line: line numbers? status bar? (follow up on #200)
- - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
- - input text multi-line: better horizontal scrolling support (#383, #1224)
- - input text multi-line: single call to AddText() should be coarse clipped on InputTextEx() end.
- - input number: optional range min/max for Input*() functions
- - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
- - input number: use mouse wheel to step up/down
-
- - layout: helper or a way to express ImGui::SameLine(ImGui::GetCursorStartPos().x + ImGui::CalcItemWidth() + ImGui::GetStyle().ItemInnerSpacing.x); in a simpler manner.
- - layout, font: horizontal tab support, A) text mode: forward only tabs (e.g. every 4 characters/N pixels from pos x1), B) manual mode: explicit tab stops acting as mini columns, no clipping (for menu items, many kind of uses, also vaguely relate to #267, #395)
- - layout: horizontal layout helper (#97)
- - layout: horizontal flow until no space left (#404)
- - layout: more generic alignment state (left/right/centered) for single items?
- - layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
- - layout: vertical alignment of mixed height items (e.g. buttons) within a same line (#1284)
- - layout: null layout mode were items are not rendered but user can query GetItemRectMin()/Max/Size.
- - layout: (R&D) local multi-pass layout mode.
- - layout: (R&D) bind authored layout data (created by an off-line tool), items fetch their pos/size at submission, self-optimize data structures to stable linear access.

- - tables: see https://github.com/ocornut/imgui/issues/2957#issuecomment-569726095
-
- - group: BeginGroup() needs a border option. (~#1496)
- - group: IsItemHovered() after EndGroup() covers whole AABB rather than the intersection of individual items. Is that desirable?
- - group: merge deactivation/activation within same group (fwd WasEdited flag). (#2550)
-
-!- color: the color conversion helpers/types are a mess and needs sorting out.
- - color: (api breaking) ImGui::ColorConvertXXX functions should be loose ImColorConvertXX to match imgui_internals.h
-
- - plot: full featured plot/graph api w/ scrolling, zooming etc. --> ImPlot
- - (plot: deleted all other todo lines on 2023-06-28)
-
- - clipper: ability to disable the clipping through a simple flag/bool.
- - clipper: ability to run without knowing full count in advance.
- - clipper: horizontal clipping support. (#2580)
-
- - separator: expose flags (#759)
- - separator: take indent into consideration (optional)
- - separator: width, thickness, centering (#1643, #2657)
- - splitter: formalize the splitter idiom into an official api (we want to handle n-way split) (#319)
-
- - docking: merge docking branch (#2109)
-
- - tabs: "there is currently a problem because TabItem() will try to submit their own tooltip after 0.50 second, and this will have the effect of making your tooltip flicker once." -> tooltip priority work (WIP branch)
- - tabs: make EndTabBar fail if users doesn't respect BeginTabBar return value, for consistency/future-proofing.
- - tabs: persistent order/focus in BeginTabBar() api (#261, #351)
- - tabs: explicit api (even if internal) to cleanly manipulate tab order.
-
- - image/image button: misalignment on padded/bordered button?
- - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
- - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
- - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
- - slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign)
- - slider: relative dragging? + precision dragging
- - slider: step option (#1183)
- - slider: style: fill % of the bar instead of positioning a drag.
- - knob: rotating knob widget (#942)
- - drag float: support for reversed drags (min > max) (removed is_locked, also see fdc526e)
- - drag float: up/down axis
- - drag float: power != 0.0f with current value being outside the range keeps the value stuck.
- - drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits)
-
- - combo: use clipper.
- - combo: a way/helper to customize the combo preview (#1658) -> experimental BeginComboPreview()
- - combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203)
- - listbox: multiple selection (WIP range-select branch)
- - listbox: unselect option (#1208)
- - listbox: make it easier/more natural to implement range-select (need some sort of info/ref about the last clicked/focused item that user can translate to an index?) (WIP range-select branch)
- - listbox: user may want to initial scroll to focus on the one selected value?
- - listbox: disable capturing mouse wheel if the listbox has no scrolling. (#1681)
- - listbox: scrolling should track modified selection.
- - listbox: future api should allow to enable horizontal scrolling (#2510)
-
-!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402)
- - modals: make modal title bar blink when trying to click outside the modal
- - modals: technically speaking, we could make Begin() with ImGuiWindowFlags_Modal work without involving popup. May help untangle a few things, as modals are more like regular windows than popups.
- - popups: if the popup functions took explicit ImGuiID it would allow the user to manage the scope of those ID. (#331)
- - popups: clicking outside (to close popup) and holding shouldn't drag window below.
- - popups: add variant using global identifier similar to Begin/End (#402)
- - popups: border options. richer api like BeginChild() perhaps? (#197)
- - popups/modals: although it is sometimes convenient that popups/modals lifetime is owned by imgui, we could also a bool-owned-by-user api as long as Begin() return value testing is enforced.
-
- - tooltip: drag and drop with tooltip near monitor edges lose/changes its last direction instead of locking one. The drag and drop tooltip should always follow without changing direction.
- - tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic.
- - tooltip: drag tooltip hovering over source widget with IsItemHovered/SetTooltip flickers (WIP branch)
-
- - status-bar: add a per-window status bar helper similar to what menu-bar does. generalize concept of layer0 rect in window (can make _MenuBar window flag obsolete too).
- - shortcuts: local-style shortcut api, e.g. parse "&Save"
- - shortcuts,menus: global-style shortcut api e.g. "Save (CTRL+S)" -> explicit flag for recursing into closed menu
- - shortcuts: programmatically access shortcuts "Focus("&Save"))
- - menus: menu-bar: main menu-bar could affect clamping of windows position (~ akin to modifying DisplayMin)
- - menus: hovering from menu to menu on a menu-bar has 1 frame without any menu, which is a little annoying. ideally either 0 either longer.
- - menus: would be nice if the Selectable() supported horizontal alignment (must be given the equivalent of WorkRect.Max.x matching the position of the shortcut column)
-
- - tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings?
- - tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits?
- - tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
- - tree node: tweak color scheme to distinguish headers from selected tree node (#581)
- - tree node: leaf/non-leaf highlight mismatch.
- - tree node/opt: could avoid formatting when clipped (flag assuming we don't care about width/height, assume single line height? format only %s/%c to be able to count height?)
-
- - settings: write more decent code to allow saving/loading new fields: columns, selected tree nodes?
- - settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file (#437)
- - settings/persistence: helpers to make TreeNodeBehavior persist (even during dev!) - may need to store some semantic and/or data type in ImGuiStoragePair
-
- - style: better default styles. (#707)
- - style: PushStyleVar: allow direct access to individual float X/Y elements.
- - style: add a highlighted text color (for headers, etc.)
- - style: border types: out-screen, in-screen, etc. (#447)
- - style: add window shadow (fading away from the window. Paint-style calculation of vertices alpha after drawlist would be easier)
- - style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc.
- - style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation).
- - style: global scale setting.
- - style: FramePadding could be different for up vs down (#584)
- - style: WindowPadding needs to be EVEN as the 0.5 multiplier used on this value probably have a subtle effect on clip rectangle
- - style: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438, #707, #1223)
- - style: gradients fill (#1223) ~ 2 bg colors for each fill? tricky with rounded shapes and using textures for corners.
- - style editor: color child window height expressed in multiple of line height.
-
- - log: improve logging of ArrowButton, ListBox, TabItem
- - log: carry on indent / tree depth when opening a child window
- - log: enabling log ends up pushing and growing vertices buffers because we don't distinguish layout vs render clipping
- - log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
- - log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)
- - log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs.
- - log: obsolete LogButtons().... (was: LogButtons() options for specifying depth and/or hiding depth slider)
-
- - filters: set a current filter that certains items (e.g. tree node) can automatically query to hide themselves
- - filters: handle wild-cards (with implicit leading/trailing *), reg-exprs
- - filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb)
-
- - drag and drop: focus drag target window on hold (even without open)
- - drag and drop: releasing a drop shows the "..." tooltip for one frame - since e13e598 (#1725)
- - drag and drop: drag source on a group object (would need e.g. an invisible button covering group in EndGroup) https://twitter.com/paniq/status/1121446364909535233
- - drag and drop: have some way to know when a drag begin from BeginDragDropSource() pov. (see 2018/01/11 post in #143)
- - drag and drop: allow preview tooltip to be submitted from a different place than the drag source. (#1725)
- - drag and drop: make it easier and provide a demo to have tooltip both are source and target site, with a more detailed one on target site (tooltip ordering problem)
- - drag and drop: demo with reordering nodes (in a list, or a tree node). (#143)
- - drag and drop: test integrating with os drag and drop (make it easy to do a naive WM_DROPFILE integration)
- - drag and drop: allow for multiple payload types. (#143)
- - drag and drop: make payload optional? payload promise? (see 2018/01/11 post in #143)
- - drag and drop: (#143) "both an in-process pointer and a promise to generate a serialized version, for whether the drag ends inside or outside the same process"
- - drag and drop: feedback when hovering a region blocked by modal (mouse cursor "NO"?)
-
- - markup: simple markup language for color change? (#902, #3130)
-
- - text: selectable text (for copy) as a generic feature (ItemFlags?)
- - text: proper alignment options in imgui_internal.h
- - text: provided a framed text helper, e.g. https://pastebin.com/1Laxy8bT
- - text: refactor TextUnformatted (or underlying function) to more explicitly request if we need width measurement or not
- - text/layout/tabs: \t pulling position from base pos + step, or offset array (e.g. could be used in text edit, menus for simple icon+text alignment, etc.)
- - text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use?
- - text/wrapped: should be a more first-class citizen, e.g. wrapped text within a Selectable with known width.
- - text/wrapped: custom separator for text wrapping. (#3002)
- - text/wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
-
- - font: arbitrary line spacing. (#2945)
- - font: MergeMode: flags to select overwriting or not (this is now very easy with refactored ImFontAtlasBuildWithStbTruetype)
- - font: free the Alpha buffer if user only requested RGBA.
-!- font: better CalcTextSizeA() API, at least for simple use cases. current one is horrible (perhaps have simple vs extended versions).
- - font: for the purpose of RenderTextEllipsis(), it might be useful that CalcTextSizeA() can ignore the trailing padding?
- - font: a CalcTextHeight() helper could run faster than CalcTextSize().y
- - font: enforce monospace through ImFontConfig (for icons?) + create dual ImFont output from same input, reusing rasterized data but with different glyphs/AdvanceX
- - font: finish CustomRectRegister() to allow mapping Unicode codepoint to custom texture data
- - font: remove ID from CustomRect registration, it seems unnecessary!
- - font: make it easier to submit own bitmap font (same texture, another texture?). (#2127, #2575)
- - font: PushFontSize API (#1018)
- - font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite?
- - font: storing MinAdvanceX per font would allow us to skip calculating line width (under a threshold of character count) in loops looking for block width
- - font/demo: add tools to show glyphs used by a text blob, display U16 value, list missing glyphs.
- - font/demo: demonstrate use of ImFontGlyphRangesBuilder.
- - font/atlas: add a missing Glyphs.reserve()
- - font/atlas: incremental updates
- - font/atlas: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
- - font/draw: vertical and/or rotated text renderer (#705) - vertical is easier clipping wise
- - font/draw: need to be able to specify wrap start position.
- - font/draw: better reserve policy for large horizontal block of text (shouldn't reserve for all clipped lines). also see #3349.
- - font/draw: fix for drawing 16k+ visible characters in same call.
- - font/draw: underline, squiggle line rendering helpers.
- - font: optimization: for monospace font (like the default one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance (need to make sure TAB is still correct), would save on cache line.
- - font: add support for kerning, probably optional. A) perhaps default to (32..128)^2 matrix ~ 9K entries = 36KB, then hash for non-ascii?. B) or sparse lookup into per-char list?
- - font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize)
- - font: fix AddRemapChar() to work before atlas has been built.
- - font: (api breaking) remove "TTF" from symbol names. also because it now supports OTF.
- - font/opt: Considering storing standalone AdvanceX table as 16-bit fixed point integer?
- - font/opt: Glyph currently 40 bytes (2+9*4). Consider storing UV as 16-bits integer? (->32 bytes). X0/Y0/X1/Y1 as 16 fixed-point integers? Or X0/Y0 as float and X1/Y1 as fixed8_8?
-
- - nav: visual feedback on button press.
- - nav: some features such as PageUp/Down/Home/End should probably work without ImGuiConfigFlags_NavEnableKeyboard? (where do we draw the line? how about CTRL+Tab)
- ! nav: never clear NavId on some setup (e.g. gamepad centric)
- - nav: there's currently no way to completely clear focus with the keyboard. depending on patterns used by the application to dispatch inputs, it may be desirable.
- - nav: Home/End behavior when navigable item is not fully visible at the edge of scrolling? should be backtrack to keep item into view?
- - nav: NavScrollToBringItemIntoView() with item bigger than view should focus top-right? Repro: using Nav in "About Window"
- - nav: wrap around logic to allow e.g. grid based layout (pressing NavRight on the right-most element would go to the next row, etc.). see internal's NavMoveRequestTryWrapping().
- - nav: patterns to make it possible for arrows key to update selection (see JustMovedTo in range_select branch)
- - nav: restore/find nearest NavId when current one disappear (e.g. pressed a button that disappear, or perhaps auto restoring when current button change name)
- - nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
- - nav: NavFlattened: init requests don't work properly on flattened siblings.
- - nav: NavFlattened: pageup/pagedown/home/end don't work properly on flattened siblings.
- - nav: NavFlattened: ESC on a flattened child should select something.
- - nav: NavFlattened: broken: in typical usage scenario, the items of a fully clipped child are currently not considered to enter into a NavFlattened child.
- - nav: NavFlattened: cannot access menu-bar of a flattened child window with Alt/menu key (not a very common use case..).
- - nav: simulate right-click or context activation? (SHIFT+F10, keyboard Menu key?)
- - nav/popup: esc/enter default behavior for popups, e.g. be able to mark an "ok" or "cancel" button that would get triggered by those keys, default validation button, etc.
- - nav/treenode: left within a tree node block as a fallback (ImGuiTreeNodeFlags_NavLeftJumpsBackHere by default?)
- - nav/menus: pressing left-right on a vertically clipped menu bar tends to jump to the collapse/close buttons.
- - nav/menus: allow pressing Menu to leave a sub-menu.
- - nav/menus: a way to access the main menu bar with Alt? (currently needs CTRL+TAB) or last focused window menu bar?
- - nav/menus: when using the main menu bar, even though we restore focus after, the underlying window loses its title bar highlight during menu manipulation. could we prevent it?
- - nav/menus: main menu bar currently cannot restore a nullptr focus. Could save NavWindow at the time of being focused, similarly to what popup do?
- - nav/menus: Alt,Up could open the first menu (e.g. "File") currently it tends to nav into the window/collapse menu. Do do that we would need custom transition?
- - nav/windowing: when CTRL+Tab/windowing is active, the HoveredWindow detection doesn't take account of the window display re-ordering.
- - nav/windowing: Resizing window will currently fail with certain types of resizing constraints/callback applied
- - focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)
-
- - inputs: support track pad style scrolling & slider edit.
- - inputs/io: backspace and arrows in the context of a text input could use system repeat rate.
- - inputs/io: clarify/standardize/expose repeat rate and repeat delays (#1808)
- - inputs/scrolling: support for smooth scrolling (#2462, #2569)
-
- - misc: idle: expose "woken up" boolean (set by inputs) and/or animation time (for cursor blink) for backend to be able stop refreshing easily.
- - misc: idle: if cursor blink if the _only_ visible animation, core imgui could rewrite vertex alpha to avoid CPU pass on ImGui:: calls.
- - misc: idle: if cursor blink if the _only_ visible animation, could even expose a dirty rectangle that optionally can be leverage by some app to render in a smaller viewport, getting rid of much pixel shading cost.
- - misc: no way to run a root-most GetID() with ImGui:: api since there's always a Debug window in the stack. (mentioned in #2960)
- - misc: make the ImGuiCond values linear (non-power-of-two). internal storage for ImGuiWindow can use integers to combine into flags (Why?)
- - misc: PushItemFlag(): add a flag to disable keyboard capture when used with mouse? (#1682)
- - misc: use more size_t in public api?
- - misc: possible compile-time support for string view/range instead of char* would e.g. facilitate usage with Rust (#683, #3038, WIP string_view branch)
- - misc: possible compile-time support for wchar_t instead of char*?
-
- - demo: demonstrate using PushStyleVar() in more details.
- - demo: add vertical separator demo
- - demo: add virtual scrolling example?
- - demo: demonstrate Plot offset
- - demo: window size constraint: square demo is broken when resizing from edges (#1975), would need to rework the callback system to solve this
-
- - examples: window minimize, maximize (#583)
- - examples: provide a zero frame-rate/idle example.
- - examples: dx11/dx12: try to use new swapchain blit models (#2970)
- - backends: report it better when not able to create texture?
- - backends: glfw: could go idle when minimized? if (glfwGetWindowAttrib(window, GLFW_ICONIFIED)) { glfwWaitEvents(); continue; } // issue: DeltaTime will be super high on resume, perhaps provide a way to let impl know (#440)
- - backends: opengl: rename imgui_impl_opengl2 to impl_opengl_legacy and imgui_impl_opengl3 to imgui_impl_opengl? (#1900)
- - backends: opengl: could use a single vertex buffer and glBufferSubData for uploads?
- - backends: opengl: explicitly disable GL_STENCIL_TEST in bindings.
- - backends: vulkan: viewport: support for synchronized swapping of multiple swap chains.
- - backends: bgfx: https://gist.github.com/RichardGale/6e2b74bc42b3005e08397236e4be0fd0
- - backends: emscriptem: with refactored examples, we could provide a direct imgui_impl_emscripten platform layer (see eg. https://github.com/floooh/sokol-samples/blob/master/html5/imgui-emsc.cc#L42)
-
- - bindings: ways to use clang ast dump to generate bindings or helpers for bindings? (e.g. clang++ -Xclang -ast-dump=json imgui.h) (WIP project "dear-bindings" still private)
-
- - optimization: replace vsnprintf with stb_printf? using IMGUI_USE_STB_SPRINTF. (#1038 + needed for string_view)
- - optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request.
- - optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335)
- - optimization: fully covered window (covered by another with non-translucent bg + WindowRounding worth of padding) may want to clip rendering.
- - optimization: use another hash function than crc32, e.g. FNV1a
- - optimization: turn some the various stack vectors into statically-sized arrays

-# Configuration
-
-Dear ImGui outputs 16-bit vertex indices by default.
-Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile dear imgui with 32-bit indices.
-You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename.
-We are providing `imconfig_allegro5.h` that enables 32-bit indices.
-Note that the backend supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.
-
-# How to Build
-
-### On Ubuntu 14.04+ and macOS
-
-```bash
-g++ -DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" -I .. -I ../.. -I ../../backends main.cpp ../../backends/imgui_impl_allegro5.cpp ../../imgui*.cpp -lallegro -lallegro_main -lallegro_primitives -o allegro5_example
-```
-
-On macOS, install Allegro with homebrew: `brew install allegro`.
-
-### On Windows with Visual Studio's CLI
-
-You may install Allegro using vcpkg:
-```
-git clone https://github.com/Microsoft/vcpkg
-cd vcpkg
-bootstrap-vcpkg.bat
-vcpkg install allegro5 --triplet=x86-windows ; for win32
-vcpkg install allegro5 --triplet=x64-windows ; for win64
-vcpkg integrate install ; register include / libs in Visual Studio
-```
-
-Build:
-```
-set ALLEGRODIR=path_to_your_allegro5_folder
-cl /Zi /MD /utf-8 /I %ALLEGRODIR%\include /DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" /I .. /I ..\.. /I ..\..\backends main.cpp ..\..\backends\imgui_impl_allegro5.cpp ..\..\imgui*.cpp /link /LIBPATH:%ALLEGRODIR%\lib allegro-5.0.10-monolith-md.lib user32.lib

-# iOS / OSX Metal example
-
-## Introduction
-
-This example shows how to integrate Dear ImGui with Metal. It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
-
-Consider basing your work off the example_glfw_metal/ or example_sdl2_metal/ examples. They are better supported and will be portable unlike this one.

- // - If the file cannot be loaded, the function will return a nullptr. Please handle those errors in your application (e.g. use an assertion, or display an error and quit).
- // - The fonts will be rasterized at a given size (w/ oversampling) and stored into a texture when calling ImFontAtlas::Build()/GetTexDataAsXXXX(), which ImGui_ImplXXXX_NewFrame below will call.

-## How to Build
-
-- You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
-
-- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
-
-- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
-
-- Then build using `make` while in the `example_emscripten_wgpu/` directory.
-
-- Requires recent Emscripten as WGPU is still a work-in-progress API.
-
-## How to Run
-
-To run on a local machine:
-- Make sure your browse supports WGPU and it is enabled. WGPU is still WIP not enabled by default in most browser.
-- `make serve` will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
-- Otherwise, generally you will need a local webserver:
- - Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):
-_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
- - Emscripten SDK has a handy `emrun` command: `emrun web/example_emscripten_opengl3.html --browser firefox` which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
- - You may use Python 3 builtin webserver: `python -m http.server -d web` (this is what `make serve` uses).
- - You may use Python 2 builtin webserver: `cd web && python -m SimpleHTTPServer`.
- - If you are accessing the files over a network, certain browsers, such as Firefox, will restrict Gamepad API access to secure contexts only (e.g. https only).

- // - If no fonts are loaded, dear imgui will use the default font. You can also load multiple fonts and use ImGui::PushFont()/PopFont() to select them.
- // - AddFontFromFileTTF() will return the ImFont* so you can store it if you need to select the font among multiple.
- // - If the file cannot be loaded, the function will return a nullptr. Please handle those errors in your application (e.g. use an assertion, or display an error and quit).
- // - The fonts will be rasterized at a given size (w/ oversampling) and stored into a texture when calling ImFontAtlas::Build()/GetTexDataAsXXXX(), which ImGui_ImplXXXX_NewFrame below will call.
- // - Use '#define IMGUI_ENABLE_FREETYPE' in your imconfig file to use Freetype for higher quality font rendering.
- // - Read 'docs/FONTS.md' for more instructions and details.
- // - Remember that in C/C++ if you want to include a backslash \ in a string literal you need to write a double backslash \\ !
- // - Emscripten allows preloading a file or folder to be accessible at runtime. See Makefile for details.
