[vtkusers] Real colours in 3D CT image(DICOM)

[Bill Lorensen]

This version of the code does not set the colors (they are commented
out) of the parts and some of the diffuse and specular values still
are > 1.0!

One last chance, please send the code with the corrections I sent
before. Run the program and send to me (not the list) a screenshot of
the results.
