annotate src/video/SDL_blit.c @ 2353:07acabba25d9 gsoc2008_iphone

SDL_uikitview is just a generic view class which SDL_uikitopenglview inherits from. The functionality found in this class relates to (right now) mouse/touch input support. The reason for putting it here is that if someone wanted to write a render driver for iPhone based around CoreGraphics rather than OpenGL ES, they could make their Core Graphics view inherit from this class as well.
