I would like to take a single path (usually will be arcs and curves)
and a Calligraphy pen description (nib width, angle) and return the
two paths that define the borders of the penstroke.

Can anyone point to or provide any examples of ways of doing this?

The only thing I can think of at the moment would be to sample the path
at some interval, and use the pen width/angle to get a pair of points
that correspond to the penstroke at that point.  The problems with this
are that I can't think of how to "sample" a curve, and the output is a
bunch of points...hardly kosher PostScript.

thanks in advance,
dylan
