## SDL_touch.h
SDL_GetNumTouchFingers() returns a negative error code if there was an error.
SDL_GetTouchName is replaced with SDL_GetTouchDeviceName(), which takes an SDL_TouchID instead of an index.
SDL_TouchID and SDL_FingerID are now Uint64 with 0 being an invalid value.
Rather than iterating over touch devices using an index, there is a new function SDL_GetTouchDevices() to get the available devices.
Rather than iterating over touch fingers using an index, there is a new function SDL_GetTouchFingers() to get the current set of active fingers.
The following functions have been removed:
* SDL_GetNumTouchDevices() - replaced with SDL_GetTouchDevices()
* SDL_GetNumTouchFingers() - replaced with SDL_GetTouchFingers()
* SDL_GetTouchDevice() - replaced with SDL_GetTouchDevices()
* SDL_GetTouchFinger() - replaced with SDL_GetTouchFingers()
