Query whether a game controller has a given axis.
extern DECLSPEC SDL_bool SDLCALL SDL_GameControllerHasAxis(SDL_GameController *gamecontroller, SDL_GameControllerAxis axis);
|gamecontroller||a game controller|
|axis||an axis enum value (an SDL_GameControllerAxis value)|
Returns SDL_TRUE if the controller has this axis, SDL_FALSE otherwise.
This merely reports whether the controller's mapping defined this axis, as that is all the information SDL has about the physical device.
This function is available since SDL 2.0.14.
