This is one area where POV could really do with some extra functions.
Charwidth, Charheight, Stringwidth and Stringheight would make some
things sooooo much easier!
In the short term, it's possible that some assistance may be found at
http://quark.gmi.edu/~redbeard/raytracing/POVRay-util.html
Bear in mind though that the "font.inc" file was written for POV 3.0,
and only works (correctly) with the font distributed with POV.
