//  Class: VisWinQuery
//
//  Purpose:
//    Handles queries. (Currently only pick & lineout). 
//
//  Programmer: Kathleen Bonnell 
//  Creation:   March 13, 2002 
//
//  Modifications:
//    Kathleen Bonnell, Mon Mar 18 09:27:06 PST 2002
//    To better control size of pick letters, changed signature of method 
//    ComputePickScaleFactor.  Add method SetPickScale, member hidden.  
//    Removed member pickScaleFactor.
//
//    Kathleen Bonnell, Tue Mar 26 16:08:23 PST 2002  
//    Moved pick-specific code to avtPickActor.  Keep a list of pick actors.
//    
//    Kathleen Bonnell, Tue Apr 15 15:38:14 PDT 2002  
//    Added support for other query types.  Specifically, Lineout. 
//    
//    Kathleen Bonnell, Wed Jun 19 18:05:04 PDT 2002 
//    Added UpdateQuery, DeleteQuery.
//    
//    Kathleen Bonnell, Tue Oct  1 16:25:50 PDT 2002 
//    Changed argument for QueryIsValid and Lineout to Line* to convey more
//    information than simply color. 
//    
//    Kathleen Bonnell, Thu Dec 19 13:32:47 PST 2002 
//    Removed member designator and method GetNextDesignator. Added 
//    argument to QueryIsValid.
//    
//    Kathleen Bonnell, Fri Jan 31 11:34:03 PST 2003 
//    Replaced char * argument of QueryIsValid and Pick methods with 
//    PickAttributes.
//    
//    Kathleen Bonnell, Fri Jun  6 15:17:45 PDT 2003  
//    Added FullFrameOn/Off methods. 
//    
//    Kathleen Bonnell, Wed Jun 25 14:30:39 PDT 2003 
//    Removed type & its Set/Get methods.  Removed unused methods
//    ClearQueries, ClearAllQueries. Removed attachmentPoint/secondaryPoint
//    and their Set methods.
//    
//    Kathleen Bonnell, Tue Jul  8 20:02:21 PDT 2003 
//    Add method ReAddToWindow. 
//    
//    Kathleen Bonnell, Fri Feb 20 12:37:26 PST 2004 
//    Added methods CreateTranslationVector, CreateShiftVector, 
//    CalculateShiftDistance.
//
//    Mark C. Miller Wed Jun  9 17:44:38 PDT 2004
//    Modified with PickEntry and LineEntry data types in vectors of pickPoints
//    and refLines. Changed some interfaces to use VisualCueInfo.
//    
//    Kathleen Bonnell, Wed Aug 18 09:44:09 PDT 2004 
//    Added Start2DMode, StartCurveMode and Start3D mode so that pick actors
//    inappropriate for the new mode can be removed.   Added optional int arg
//    to ClearPickPoints method.
//    
//    Jeremy Meredith, Wed May 19 14:15:58 EDT 2010
//    Account for 3D axis scaling (3D equivalent of full-frame mode).
//
//    Brad Whitlock, Fri Aug 27 11:28:26 PDT 2010
//    Add an id argument to UpdateQuery.
