[vtkusers] vtk3.2beta bug

[johnny carroll norris]

Hello,

vtkUnstructuredGrid::ShallowCopy() fails to pass through the cell information.
If you use

   this->GetOutput()->ShallowCopy(this->GetInput());

in a custom filter derived from vtkUnstructuredGridToUnstructuredGridFilter,
the output will have the points and point data, but no cells.
