[vtkusers] Extents? Surely it's wrong this way? : was ....

Perfect. Thanks for the help. All is well now. One last question, Is there 
an equivalent that can be used on vtkDataObject?
ie
vtkSource *s = mysterydataobject->GetSource()
if (s) s->UpdateWholeExtent()

replace with
mysterydataobject->SuperDooperUpdateWholeExtentReally();

I guess the nearest is
mysterydataobject->SetUpdateExtent(0,-1,0,-1,0,-1)
mysterydataobject->Update()

Thanks to both of you. All my filters are behaving as expected again and I 
won't have any more sleepless nights worrying about Extents.
