-This will be called once for each event pushed into the SDL queue. This may be
-called from any thread, and possibly in parallel to SDL_AppIterate. The fields
-in `event` should not be free'd (as you would normally need to do for
-SDL_EVENT_DROP_FILE, etc), and your app should not call SDL_PollEvent,
-SDL_PumpEvent, etc, as SDL will manage this for you. Return values are the

-SDL_EVENT_QUIT, etc.

-One can still use their own event filters and watchers. Filters set with
-SDL_SetEventFilter will run before SDL_AppEvent, and if it filters out the
-event, SDL_AppEvent will not run at all. Watchers set with SDL_AddEventWatch
-will run in serial to SDL_AppEvent, as SDL_AppEvent itself is built on top of
-an event watcher; which one runs first is not guaranteed.
