Most subclasses of vtkCell3D do not return terminated lists for vtkCell3D::GetFacePoints
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
On [1] it says about vtkCell3D::GetFacePoints: "Get the list of vertices that define a face. The list is terminated with a negative number."
This is not true for most (all?) implementations of vtkCell3D (tetra, wedge, ...).
The behaviour should be changed to terminated lists, or GetFacePoints should also return the point count.
