[vtkusers] LOD filter for glyphs

[Amy Squillacote]

Hi Patrick,

You could try using vtkMaskPoints in your pipeline before the 
vtkGlyph3D. This filter allows you to "turn on" only every nth point in 
your dataset. See 
http://www.vtk.org/doc/nightly/html/classvtkMaskPoints.html for more 
information.
