//  Class:  avtLineoutActor
//
//  Purpose:  Responsible for creating the visual cue actors for a Lineout. 
//
//  Programmer:  Kathleen Bonnell 
//  Creation:    March 22, 2002 
//
//  Modifications:
//    Kathleen Bonnell, Wed Jun 19 18:05:04 PDT 2002
//    Added SetLineWidth/Style, GetDesignator, and overloade Set Point methods
//    for doubles.
//
//    Kathleen Bonnell, Tue Oct  1 16:07:40 PDT 2002   
//    Added members 'hidden' and showLabels, methods GetAttachmentPoint, 
//    SetShowLabels.  Added two actors for labels to be positioned at the 
//    endpoints.
//
//    Kathleen Bonnell, Fri Jun  6 15:08:45 PDT 2003 
//    Added Translate and ResetPosition methods. 
//    
//    Kathleen Bonnell, Wed Jun 25 15:16:42 PDT 2003  
//    Changed arguments to SetAttachmentPoint, SetPoint2 from an array to
//    3 values.
