[Paraview] Do Clip and Tetrahedralize Have A Bug in 2.2.1?

[Kent Eschenberg]

Does the tetrahedralize filter have problems with curvilinear grids?

Contours were drawn using the ParaView tutorial data file "bluntfin.vts"; 
then again after using the tetrahedralize filter; then again after running 
the input data through the clip filter (using the box function and with 
InsideOut on). The image is at

I am just guessing but it seems that clip converts ints output to 
tetrahedrons in this case.

I would have expected the plots from clip and tetrahedralize would be the 
same. And I had thought that they would both look like the plot using the 
original data.

Comments?
