Fixed issue when points are skipped by vtkGlyph3D.

vtkPVGlyphFilter assumed that IsPointVisible() is called for all points
in the input dataset. That's not the case. The vtkGlyph3D can skip
calling this method for points that it rejects due to ghost-cells or
other masks. That was causing pvcs.Flow2 test fail in parallel. This
fixes that issue.
