I think the glyphs try to deal with edges because if they didn't, then
they would flow out into whatever right or left padding had been placed
around the image when the panel was created.  Something I've noticed is
that when I create tiles for the chromosomes I'm working on the panels
don't line up because the bump position in one panel is not accounted
for when the next panel is drawn.
