[vtkusers] How to generate smooth line

[Dominik Szczerba]

I use the tubeFilter for that with datasets of about a milion segments
and it fits into 2GB.

Smoothing lines is a problem for me too: the smoothFilter works very
well but only for polygons, not lines. For the moment I just smooth them
myself, but would be glad to have it done the vtk way.
