// .NAME vtkSMMultiDisplayProxy - For tiled diplay (what on client).
// .SECTION Description
// This class has an unfortunate name ...  It always collects and displays
// the LOD on node zero (client when we enable client server).
// TODO: I wonder if we can get rid of this class altogether!
// It doesn't really do much.
