Perhaps the X video extension can be used for it? It can be used to render
something to an off-screen buffer and let the video card scale and display
it. That's what Windoze also does e.g.  when you have a TV card or when
viewing a DVD. Unfortunately, this is not yet supported very well by XFree86,
but couldn't this somehow be used to draw a window into off-screen video
memory and then let the video card scale it without any speed loss?
