Query whether a gamepad has a given axis.
SDL_bool SDL_GamepadHasAxis(SDL_Gamepad *gamepad, SDL_GamepadAxis axis);
|axis||an axis enum value (an SDL_GamepadAxis value)|
Returns SDL_TRUE if the gamepad has this axis, SDL_FALSE otherwise.
This merely reports whether the gamepad's mapping defined this axis, as that is all the information SDL has about the physical device.
This function is available since SDL 3.0.0.
