[vtkusers] vtkCell

[Murat Aydin]

In addition to clipping, there is another filter that increase resolution by 
dividing each triangle into 4 triangles,thus increase number of cells (i 
couldnt remember its name, i am new to VTK).
I have noticed that after the increase in number of cells, the "OriginalID" 
array preserves the IDs.The children cells have the same value with the 
parent. Thank you for your help and patience.

Kind Regards
murat
