No, I specifically looked at the wireframe renderer.

Yes it does....

And it does.

I don't know what you mean by surface edges.

Sorry to keep contradicting you, but yes, it does, I just tried  
that.  In fact, if you use the OpenGL renderer, kQ3FillStyleEdges,  
kQ3BackfacingStyleRemove, and kQ3IlluminationTypeNULL, it looks the  
same as the wireframe renderer with kQ3BackfacingStyleRemove.
