Added SDL_GL_RETAINED_BACKING to SDL_GLattr enum. Retained backing means the memory for color buffers, depth buffers, etc cannot be overwritten by other applications between frames. The default for this setting is 'on'. I wanted to add this because turning retained backing off on iPhone dramatically increases performance.
