[vtkusers] Breaking vtk pipeline

[N Smethurst]

A deep copy makes the new object independant from the one being copied, so 
anything you do with the original (here the reader output) will have no 
effect on the new poly data object.

So, in effect, you can do what ever you want to the reader after doing a deep 
copy of its output, and your pipeline should stay intact.
