annotate src/SDL_compat.c @ 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.
