So what you're saying is that a backend could either implement repeating
by native methods - e.g. calling SDL_EnableKeyRepeat() in the SDL
backend - or there would be code in OSystem to automagically generate
"fake" keyboard events as a fallback?

I.e. there would be a pollEvent() in OSystem that would only check for
"fake" events. The individual backends would still define pollEvent() to
call the original one, before doing their own stuff. On key down/up
events, they could optionally call functions i OSystem to set up/cancel
the generation of "fake" keyboard repeat events.
