You should see the machinations I went through to avoid coincident
surfaces in RoundEdge in the Object Collection. Also in the Object
Collection, the GemCuts user manual has a warning that setting objects
(in contrast to gem objects) are not intended for use with transparent
textures. The reason is that I made no attempt to eliminate internal
surfaces, but with that comes a high likelihood of hidden coincident
surfaces. Now you have me wondering if I should include a warning not
to difference that Tiffany solitaire setting from... uh, a clay
impression? A Styrofoam box?

Object Collection submissions are under the LGPL license, and my other
independent submissions are under the GPL. I've also submitted
modifications and supplements to POV-Ray distribution scene files, which
are covered by Creative Commons. All these licenses have explicit
warranty disclaimers. So, the user's problem, not mine. :p
