[vtkusers] Using tensors with cell data

[Jose Paulo Moitinho de Almeida]

Hello

Am I misreading the code or some of the "tensor routines" (eg 
vtkExtractTensorComponents and vtkTensorGlyph) will not work with cell data?

If this is true, is it just a "to be done" or is there another reason?

Regards

Ze Paulo
