SDL offers no way to disable or bypass this offscreen copy of the 
display. This is one of the performance hurdles for fullscreen scrolling 
btw, or at least, used to be, machines have gotten faster lately.

There are actually two odd workarounds that may not help. You initialize 
a fullscreen display with HWSURFACE and not DOUBLEBUF you will draw 
directly to the screen. But that only works double buffered. 
Alternatively, you can pass OPENGL and not DOUBLEBUF and you will also 
be rendering direct to the screen, and that works fullscreen or 
windowed. In both these cases you'll need to watch for those VIDEOEXPOSE 
events and be sure to clean up the display.
