[vtk-developers] patch for vtkPolyDataConnectivityFilter

[Amy Squillacote]

Hi all,

In recently trying to use vtkPolyDataConnectivityFilter, I discovered 
that if you turn coloring on (to save the component id to a point data 
scalar array), the array marked as scalars in the input point data is 
not copied through to the output. Additionally, the "coloring" array has 
no name. The attached patch corrects these two issues. The coloring 
array is added to the point data and set as "scalars", but the input 
point data scalars are not removed. Also, the coloring array is named 
"RegionId" to match the name used in vtkConnectivityFilter.

If no one sees a problem with this, I will commit the change. Would it 
be possible to put this change on the 5.2 branch as well?

- Amy
