I don't know how (or if) SDL does callbacks for window resizing, or moving,
or screen update, or mouse movement. However, I would expect it to be
similar to Hatari SDL function call Audio_CallBack() in hatari/src/audio.c

I just looked at line 413 of hatari/src/main.c This is the comment for
Main_WarpMouse() to ignore a mouse event. Maybe too much is ignored
by bIgnoreNextMouseMotion for SDL2.

SDL_AddTimer() SDL_AudioSpec() SDL_AddEventWatch() are some
SDL callbacks that I found with a google search.

I think I've said more than I know about what I think I said. :)
