// .NAME vtkPCellDataToPointData - Compute point arrays from cell arrays.
// .SECTION Description
// Like it super class, this filter averages the cell data around
// a point to get new point data. This subclass requests a layer of
// ghost cells to make the results invariant to pieces. There is a
// "PieceInvariant" flag that lets the user change the behavior
// of the filter to that of its superclass.
