Nightly : BackFace/Frontface bug ?

[John Biddiscombe]

Dear vtk'ers

Nightly release

When an actor has rendering = surface, backface and frontface culling work
as expected. When rendering = wireframe, no culling occurs (either front or
back).

Not sure if this is a bug or an OpenGL "feature", but I don't see why
culling shouldn't work in wireframe mode.

This bug has not appeared overnight, but I wasn't sure about it before....

(apologies if this isn't a bug).
