[vtk-developers] Additions to vtkTriangle

[Philippe Pébay]

Yes David; thanks for the suggestion!

I am also thinking of a 3rd addition: GetFirstEdgeNeighbor(), which would
only return one vtkIdType (as opposed to a vtkIdList) and would be
sufficient in the many cases where the triangles are located on a manifold
variety, be it immersed in 2 or 3 dimensions.
