[vtk-developers] save the coordinate with the color of point

[David Doria]

As I mentioned before, please continue this discussion on the
VTK-users mailing list rather than this list (the VTK-developers
mailing list). Also, you should make a 10 line, compilable example of
the type of data set you have - your question is about writing the
data set and has nothing to do with the majority of the code you sent.
