"""Set of cursor resources available for use. These cursors come

in a sequence of values that are needed as the arguments for

pygame.mouse.set_cursor(). to dereference the sequence in place

pygame.mouse.set_cursor(*pygame.cursors.arrow).

Here is a list of available cursors; arrow, diamond, ball,

broken_x, tri_left, tri_right

There is also a sample string cursor named 'thickarrow_strings'.

The compile() function can convert these string cursors into cursor byte data.
