[Paraview] Creating ImageData w/Programmable Source

[Eric E. Monson]

That works great -- thanks!

Now that you pointed me in the right direction, I can see how both  
WholeExtent and UpdateExtent were [0, -1, 0, -1, 0, -1]  in the output  
with my original script. Maybe it should have been obvious, but I  
didn't know enough to look for that.

It also seems to work fine if I set these in the main script:

pdo.SetWholeExtent(0,9,0,9,0,9)
pdo.SetUpdateExtentToWholeExtent()

Thanks again,
-Eric
