66 Set to 1 to use a system memory back buffer for the screen in full screen mode. Some programs on other systems assume their is always a back buffer even though the SDL specification specifies this is not the case. The current RISC OS implementation uses direct writes to the screen if a hardware fullscreen is requested.

68 Set to 2 to use an ARM code full word copy. This is faster than the standard back buffer, but uses aligned words only so it is possible (but unlikely) for it to corrupt the screen for 8bpp and 16bpp modes.

70 Set to 3 to use a RISC OS sprite as the back buffer. This is usually the slowest for most SDL applications, however it may be useful in the future as Sprite acceleration is added to various hardware that runs RISC OS.
