SDL/test/testautomation_joystick.c
Sam Lantinga 2991b9f6ac SDL now represents gamepad buttons as positional elements with a separate label 
This gives applications and binding systems a clearer view of what the hardware is so they can make intelligent decisions about how to present things to the user.

Gamepad mappings continue to use abxy for the face buttons for simplicity and compatibility with earlier versions of SDL, however the "SDL_GAMECONTROLLER_USE_BUTTON_LABELS" hint no longer has any effect.
