Yeah -- is SDL's clipping routine really optimized enough to make doing it
worthwhile? IMO you'd be probably better off writing your own localized
clipper. The one advantage I see is that you could use SDL's predefined
rectangle struct and that's no big deal -- you could do that anyways. I'd
just prefer to see people writing their own more specialized routines for
when they need to.
