it is not working.  The texture shows up on the untextured surfaces (such as
clipping surfaces from differences and intersections) but not on the textured
surfaces.

A quick search shows a post from 2008 requesting extension of the texturing
system to allow overlays:

apparently you can only layer textures over previously textured objects if the
object in question is a single primitive.

This makes it nearly impossible - or, at least, unnecessarily dificult - to do
complex textures on csg objects.

Correct me if I'm wrong.
