[vtkusers] cell subset filter?

[Tim Tautges]

Hi all,
   Is there some type of filter (or some other method to accomplish 
this) which takes as input an unstructured grid and outputs a subset of 
that, such that the cells aren't actually copied but just referenced? 
The closest I've found is vtkExtractUnstructuredGrid, but that allows 
you to define only one contiguous range of cell ids, whereas I'd like to 
define an arbitrary list of ids.

Thanks.
