I would like to do a wrap around scroll on a bitmap.  I tried using
a ScrollRaster call but it was too darned slow and the colors were
messy (it scrolls one plane at a time.)  I want to do a smooth scroll
from bottom to top with the stuff going off the top re-appearing on
the bottom.  It would be nice to be able to change the graphics before it
re-appears on the bottom (would be easy if the bitmap was taller than the
viewable area.)  HOW DO you do this? The RKM's don't give any clue at all
how this could be done.  If you haven't guessed, this is for a character
generator type of thing.
