    In development the problem I ran into was getting the .gif right. I had to
revise it several times, note the 2b. Everything but what I wanted "raised" had
to be exactly the same black pixels. Almost was not good enough. Anything else
had bumps in all the wrong places. Doing it today, I would not use .gif as there
is are too few intensities for smooth transitions.
