Thumbstick axis values range from SDL_JOYSTICK_AXIS_MIN to
SDL_JOYSTICK_AXIS_MAX, and are centered within ~8000 of zero, though
advanced UI will allow users to set or autodetect the dead zone, which
varies between gamepads.
Trigger axis values range from 0 (released) to SDL_JOYSTICK_AXIS_MAX (fully
pressed) when reported by SDL_GetGamepadAxis(). Note that this is not the
same range that will be reported by the lower-level SDL_GetJoystickAxis().
