	Look at the way graphics memory for the Bridgecard is arranged.
It's addressed in three different locations, and in each one, the same
memory is organized differently. I can easily imagine that a simple
system can be devised to make the same region of memory look both
pixel-packed and bit plane'd. Then, both the graphics.library and the
34020 would be happy.
