// primitive index and "triangle-in-primitive" index to the op function,
// 3) it also passes the absolute vertex numbers in the primitive so they
// can be used to look up normals/colors/tcoords, and 4) fixes some
// problems with vertex ordering which caused FRONT/BACK confusion with
// normals and lighting.
// With this, we can construct a new TRIANGLE GeoSet from any area GeoSet.
