Well, yes.  I played around with a lot of different ways of doing this
and this seemed best - I decided that building all the tile combinations
dynamically would take far too long, and would have its own memory
management issues.

Each tile-pair is 24 bytes, and I need two copies of each, one for the
reversed PF registers and one for the normal PF registers.  I can't
remember the exact numbers, but I think I figured that acceptable maps
could be constructed with ~10 such tile-pairs, which would fit in two
pages.

Thanks,
