Re: [pygame] Surfaces with Transparent Backgrounds

Yeah, subsurfs rock the house.  They are also faster because they
don't copy any memory.  If you blit into img, for instance, it will be
updated in the subsurfs.  If you want to tint the sprite later, for an
effect or something, you can tint img and all of the frames will be
tinted as well.
