The current RGBA->RGBA behavior was designed for SDL_OPENGLBLIT (obsolete)
where you want to define a HUD and blit updates into it without destroying
the alpha channel.
I won't be changing that behavior in SDL 1.2, since too many applications
rely on those semantics, however alpha blending semantics are open for
discussion for SDL 1.3
