Yes.  As the IRTC allows, I'm updating the macros, and working on a
modeler, too.  I managed to figure out a way to include four-sided
faces in the original mesh, along with three-sided faces, although
the four-siders will have to be coverted to triangles for the final
output.  It eliminates some artifacts of the Loop method when
applied to certain shapes.

I also hope to have support for sharp and border edges, which is
lacking in the present version.

The best approach is using a technique that packages each face of the
original mesh with the other control points needed to make the triangles
that go with that face; this allows faces to be rendered independently
of the rest, at great memory savings.
