* As this function implicitly calls SDL_PumpEvents(), you can only call this
* function in the thread that set the video mode.

* SDL_PollEvent() is the favored way of receiving system events since it can
* be done from the main loop and does not suspend the main loop while waiting
* on an event to be posted.
* SDL_PollEvent() is deprecated as some sensors and mice with extremely high
* update rates can generate events each time this function is called.
*
* The common practice is to fully process the event queue once every frame,
* usually as a first step before updating the game's state:
