Ax ScaleSurfaceSlow() in favor of ScaleSurface()

Browse Source 
ScaleSurfaceSlow() uses DrawPixel() instead of SDL_FillRect() to scale a
given surface, which is slow and inefficient, and makes it less likely
that the game could be moved to SDL_Render.

Unfortunately, it has this weird -1,-1 offset, but that will be fixed in
the next commit.
