\brief Used to smooth and set analog tank control values from analog inputs (gamepad).
Also used to set boolean gearup, geardown values.
\param[in] padSmoothing describes how quickly the control values applied to the vehicle blend from the current vehicle values towards the raw analog values from the gamepad.
\param[in] rawInputData is the state of all gamepad analog inputs that will be used control the vehicle.
\param[in] timestep is the time that has passed since the last call to PxVehicleDrive4WSmoothDigitalRawInputsAndSetAnalogInputs
\param[in] focusVehicle is the vehicle that will be given analog control values arising from the gamepad inputs.
