I see I forgot to add a subject line in my post, sorry about that.  Here it
is again:

I'm not really a new user, but this question is so basic (and I'm such an
amateur) that this seemed like the right group to ask.  Ok, here's the deal:
I'm trying to align text around a circle.  I have been trying by making the
individual letters, then translating them down, and subsequently rotating
them into place.  However this gives 2 problems: 1. the origin is in the
lower left of each letter, so after rotating they still don't align nicely
and instead slope to the right a bit, and 2. since I don't know the width of
each character I can't space them correctly.
Now I know in the Win32 GUI there is a function which tells you the width of
a character, but I'm guessing this isn't implemented in povray.  So my
question is: is there any way to calculate the width of each character?  Or,
alternatively, does anyone know how to reach the same effect in a different
way (perhaps with a macro)?

TIA,
  Zero

Although I'm quite new to povray myself, I have an idea what you could do.
Try getting megapov, it supports centering of text, and thus would solve your
problem.

Note that for now that code requires MegaPOV or one of its offspring.  It
will be supported in POV 3.5 as well.

Yep, I noticed that.  I downloaded MegaPOV, and so far I'm very happy with
it :-)
