Are you sure? I thought it always points to the entire virtual screen, 
at least I'm almost sure that's how it used to be a few of years ago. 
The old way of page flipping (before the invention of 
create_video_bitmap()) was to use scroll_screen() and keep track of 
where to draw on the virtual screen.  So if the semantics of screen 
chagnes, I think it might break old programs.
