[vtkusers] Visualisation of cell-based data.

[Bertwim van Beest]

Thanks! As a VTK-novice,I am reading the VTK-book. From the book I
understood that the user himself has to come-up with interpolation
schemes between the two sets of data, but apparently this is not true!?

Anyway, I am going to try it out.
