I believe "SDL_Flip()" 'does the right thing(tm)' when it's not actually
doing true double-buffering.  In otherwords, SDL_Flip() will fall-back
and end up being a call to SDL_UpdateRect() for the entire surface. :)

If there are probs., let me know.  It's easy enough to build a wrapper
that does do the "if" decision.
