sdl-ios-xcode: src/video/SDL_blit

annotate src/video/SDL_blit_N.c @ 3844:332a59e39ce1 SDL-ryan-multiple-audio-device

I really don't want to update these last two audio backends...I added an error that says if no one complains, the backends will be removed eventually. So if anyone ever wants them and they care enough to speak up, we'll know to do something about it. If no one does, that's less code to maintain. :)
