diff include/SDL_video.h @ 5169:4d39eeaad00b
Added a way to get a framebuffer interface for a window, and also a way to create a software renderer for an arbitrary surface.
The software renderer has been re-routed to use the framebuffer interface, which makes it possible to have software rendering available even on simple ports.
