[vtkusers] How to "clean" a polydata mesh? (holes, etc)

If Tolerance is set to 0 (which it is by default), then only exactly 
duplicate points will be merged.  If the Tolerance is non-zero, then 
points within that distance of one another will be merged 
together.  Point merging could explain the changes in topology you're 
seeing.  If you do not want points to be merged at all, set PointMerging to 0.
