// This is a hack to workaround SDL_hidapi using window messages to detect device
// removal/arrival, yet no part of SDL pumps messages for it. It can hopefully be removed in the
// future when SDL fixes the issue. Note this is a separate issue from SDL_HINT_JOYSTICK_THREAD.
// Also note that SDL_WaitEvent may block while device detection window messages get queued up,
// causing some noticible stutter. This is just another reason it should be fixed properly by
// SDL...
