[vtk-developers] Should these tests pass here?

[David Gobbi]

As for the other tests... my guess is that they're all doomed to fail.
The dark lines indicate that your gfx does not do two-sided lighting
for wireframes, frames around back-facing polygons are dark when
they should (by default) be lit in VTK.

One strange thing, though: the failures indicate that all of those
HyperTreeGrid renderings are showing us polygons that are facing
_away_ from us.
