even though he wasn't asking, i'll drop this point on you guys.  anything that
directly accesses the video hardware will break the second you try to port
it to a SUN machine.  SUN does not allow direct framebuffer access, you
have to use one of the video libraries to do anything "directly" with the
framebuffer.  so, direct access to the video hardware would be a Bad Idea (TM)
in general.
