Me too. Can this be done quickly? I tried doing something like this
in real time with a LIVE digitizer. It worked, but was slow. The best
I could figure to do was go blit each column of pixels on the left
side of the screen to the corresponding position on the right hand side
of the screen.

Unlike Mr. Hinds, I am not convinced that a better way exists, but would
be very interested if someone finds one.
