The code works by converting Bezier splines from postscript to povray.
There are two cases it handles: closed Bezier splines that are filled
and non-closed Bezier splines that are stroked.  A closed filled spline
is pretty much the same as what is needed for a POVRay prism, so the
conversion is pretty much copying over the points in the new format.

The stroked path is converted into a prism by considering its width
and approximating the edges of the area that is actually filled.

You'd need to change this code by moving these points "outward".  It
doesn't seem particularly easy, or I'd just do it.  Some approach like
you described earlier should work, if you correctly handle all the
details.

I don't think you really care about infinite precision for the text
backdrop in the same way you do for the text.  I agree that it's nice,
but I don't see how you achieve this anyway even if you write your
own code.  There will be some approximations involved either way.
