Hmm... should this be implemented in DirectDrawSurface::Blt()?

I'd say it'd be a bit faster than the current implementation, at least in most cases :P

Sorry it took so long for me to reply, I've had a stroke of bad luck recently and had lost my will to code for a short time, and my will is back :) If there's anything I hate, it's losing my will to code, there isn't much else that's worse :P
