A binding to SDL_PushEvent is needed

A binding to the SDL_PushEvent function is needed. In my code I plan to use the blocking function SDL_WaitEvent on the main thread, and use SDL_PushEvent to unblock the main thread so I can do rendering code, or whatever.

Sure, I'll take a peek at this once we're compiling again
