No.  What was explained was that I had to scale the text object by 10000 
to make the problem visible to the naked eye.

It appears that as the truetype font is parsed, a little error is added 
to the z component of every control point.  Since this is not reported 
with other splines or polygons*, I must assume that it is a problem with 
the code that converts the 2D set of control points of a truetype font 
to POV 3D points.

*I'm downloading RC2 as we speak, I'll test my theory tonight.
