     -The semantics of each unsigned char in the ghost arrays changes:
      Instead of storing a numeric value representing how far a cell is
      from the boundary, it is now a bit field specified by
      vtkDataSetAttributes::CellGhostTypes and
      vtkDataSetAttributes::PointGhostTypes.  The bit field is consistent
      with VisIt specs.
    - Previously, filters strip all ghost cells they request from upstream
      before finalizing the output. This is no longer done.
    - vtkUniform grids previously supported blanking through member arrays
      vtkUniformGrid::CellVisibility and
      vtkUniformGrid::PointVisibility. These arrays are removed and the
      blanking functionality are supported through the new ghost arrays
    - the "vtkGhostLevel" arrays for cell and point data are renamed to
      vtkDataSetAttributes::GhostArrayName() ("vtkGhostType").
    - the version for VTK Legacy files is increased to 4.0 and the version for
      VTK XML files is increased to 2.0. When reading older files we
      convert vtkGhostLevels array to vtkGhostType.
