Please add example how to poll for events with SDL2

[oschettler]

I don't get this to work. With the standard setup, if I include this code in loop() (which is run in a separate thread), the app crashes in SDL_PollEvent()

  SDL_Event event;
  while (SDL_PollEvent(&event)) {
    switch (event.type) {
      case SDL_QUIT:
        running = 0;
        break;
  }}

This ist the output:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'nextEventMatchingMask should only be called from the Main Thread!'
