// .NAME vtkSelectionRepresentation
// .SECTION Description
// vtkSelectionRepresentation is a representation to show the extracted
// cells. It uses vtkGeometryRepresentation and vtkPVDataRepresentation
// internally.
// .SECTION Thanks
// The addition of a transformation matrix was supported by CEA/DIF 
// Commissariat a l'Energie Atomique, Centre DAM Ile-De-France, Arpajon, France.
