[vtkusers] clipping structured points datasets

[Christopher M. Navarro]

I've tried that but that doesn't seem to be the way SetVOI was 
implemented.  If I do extract VOI on my large structuredpoints set and ask 
for the number of points using the default flags, I get the correct 
(original) value, if I now do SetVOI() to the bounds of the larger region, 
I should get the same value back but I don't.  I get a very small number, orders of 
magnitude smaller than it should be.  Any other ideas on how I can do what 
I want?
