[vtk-developers] Should these tests pass here?

[David Gobbi]

Most of the dashboard failures that you see are due to
vtkHyperTreeGridGeometry.  I took a peek at the code
it uses to generate boundary polygons (in the ProcessLeaf3D()
method), and the code makes no attempt to produce the correct
polygon winding.  The other VTK geometry filters make sure that
polygons are wound so that normals face outwards.  I've CC'd
Philippe because he wrote the code.
