Why not provide it as an *extra* feature, rather than a change of how windowed mode works? Add an SDL_FASTWINDOW flag or something... (Will just be ignored by older SDL libs, and not requested by old applications, so it shouldn't break anything. Some new applications might need to check whether or not they got it, though.)

AFAIK, that blit is always performed (and clipped :-) by the OpenGL driver, regardless of platform, so that shouldn't be an issue.
