Made Blitting more permissive

SDL_BlitSurface's documentation (https://wiki.libsdl.org/SDL_BlitSurface) notes that "Blits with negative dstrect coordinates will be clipped properly".

Looking at the source code for SDL_UpperBlit() convinced me that dstrect coordinates that were too big would also be handled appropriately.

Fixes #2225.
