Well, the results *look* correct. I implemented the formula you suggested,
and the parse is still pretty quick. I tested a 100x100 mesh on my P2 650 at
work with lots of memory-hogging programs running on it, and the parse was
still under a minute.

I cancelled the version from pbs-f that I posted from work and will cancel
the others when I get home, but I might run several tests, or at least get
confirmation from ABX that my function is correct, before I post this new
version.
