// .NAME vtkPVArrowSource - A quick fix for a bug.
// .SECTION Description
// This class does nothing but tell the pipeline it can generate pieces.
// This is a quick fix for a bug with glyphs and multidisplay with
// the zero empty option.  Zero does not update arrow when created.
// Glyph updates zero but not others.  Transmit poly data hangs.
// The correct solution is to not connect the pipeline
// on this seudo client.  I can get rid of this class then.
