[vtkusers] how to use PolyData::GetPolys()?

[Dominik Szczerba]

I still dont get how the GetNextCell works but I cann access the raw int 
connectivity array - I guess PolyData::GetPolys::Get*Cell methods base 
on it. Unfortunately it doesnt work any faster, against as promised in 
the docu. I get ~ 5x better performance using an ugly glut code on the 
same dataset. Missed anything?
Thanks,
Dominik
