Indeed -- it's there now :)

Well, I tried to use text.vshift.char(0.5), but that didn't work
(deprecated?). Is that the same as text.vshift(0.5)?

This might be a possibility. What I need this for at the moment is
placing labels in circular graph nodes. I'm thinking about writing an
automated graph algorithm visualization program (for producing slides
for an algorithm class I'm teaching), and PyX seems like a good thing
to use. (I'll probably write a separate module for graph drawing,
which might be useful to other PyX users as well.)

If I place several nodes alongside each other, it may be good to have
the labels aligned by their baselinge, so that (e.g.) b and g are
properly aligned. However, if the nodes are scattered all over the
place, simply aligning based on the total height of the character will
"fill out" the node more, and seem less vertically skewed. (I could,
of course, use only capital letters... Or numbers... Then there would
be no problem :)

Anyway, thanks for your help. I'll experiment a bit with shifting and
aligning and see what I end up with. (Maybe I'll just use dotted nodes
with external labels.)
