[Visualpython-users] VPython works on Python 3

After quite a lot of changes to FontTools and a few changes to
ttfquery, I've managed to get 3D text working on Python 3, which was
the last thing needed to make a Python 3 version of VPython. I'll be
in France for a couple weeks so there won't be a Python 3 version
instantly, as I need to clean up some stuff. I'm accompanying Ruth
Chabay, who has been invited to give a talk at an international
physics education conference in Reims. She's going to talk about the
computational modeling our physics students do using VPython.

The problems I had to overcome were of course in areas where the 2to3
conversion just couldn't do the job, due to data interpretation
issues. I even found a couple of cases in ttfquery where there was N/2
(giving 1.5 if N is 3) which should have been N//2 (giving 1 if N is
3). There was also a case of map returning a map instead of a list,
and list(map(....)) wouldn't work.
