[vtkusers] refinement of iso surface

[Dale "Luke" Peterson]

> If you mean "refine" as smoothing use vtkWindowedSincPolyDataFilter.

I guess I would like more points to be added in areas where the
curvature is high so that the surface is more accurately represented.
Does the Sinc filter do that?  If not, is there something like [0] or
[1] in VTK?
