Yes, but there are virtually no SDL backends that implement 
accelerated alpha blending at this point - and the primary reason is 
probably that many of the underlying APIs don't support it. Many 
support opaque blits though, and I think most of those also support 
colorkeyed blits.

Yeah. :-/

Well, there is OpenGL, but unfortunately, that's not the Holy Grail 
either for various (rather "stupid") reasons. (See the SDL 1.3 
thread.)
