[vtkusers] vtkQuadraticTetra cell data displaying bug in vtk 4.2.1

[João Cunha]

I got into similar trouble dealing with a data file including quadratic
hexahedrons some time ago and the suggestion from Mathieu Malaterre was
to use VTK from CVS.
I've not tried that yet hoping that version 5 will solve the problem.
May be the same problem exists with quadratic tetrahedrons.
