support for cell data in TensorGlyph
I am a huge fan of the TensorGlyph visualization. However, I have cell based data (orientation tensors), that do not make sense to display at the node points.
Therefore, I am requesting that TensorGlyph also support cell based data.
I'm willing to try to hack this myself, but I have not done any work on vtk code in the past, so if someone could point me to an example of a filter that can handle both cell and point data it would be helpful.
