//  Class:  avtLabelPlot
//
//  Purpose:
//      A concrete type of avtPlot, this is the Label plot.
//
//  Programmer: Brad Whitlock
//  Creation:   Wed Jan 7 14:58:26 PST 2004
//
//  Modifications:
//    Brad Whitlock, Wed Dec 15 10:48:35 PDT 2004
//    Removed SetVarName.
//
//    Brad Whitlock, Wed Aug 3 18:04:15 PST 2005
//    I made it use a avtLabelsMapper so we can label subsets.
//
//    Kathleen Biagas, Wed Feb 29 13:09:36 MST 2012
//    Added GetExtraInfoForPick.
//
//    Kathleen Biagas, Thu Apr 13 11:06:13 PDT 2017
//    Use vtkMappers instead of custom renderer, for VTK-8.
