[Paraview] AppendAttributes issue

[Andy Bauer]

The problem is that PV is looping through your points in a different order
for the unstructured grid as you do for the image data.

What you can do is use the Programmable Filter to "fix" this looping
mismatch. Attached is a pvsm which include a Programmable Filter to do that
flip. Note that I had to manually specify the image data extents (637 and
511) in the Python indexing part so if you have a different dimensioned
data set you'll have to edit that to match your specific case.

Best,
Andy
