//              - use of optimisation in SelectMgr_ViewerSelector
//              -> Best management in detected entities...

#define BUC60569  //GG_051199 Enable to select the local context 
//                in any case and especially in multi selection mode.
//                Note that right now when an hilighted owner is selected
//                this owner is unhilighted,this permits to see the selection!
//                Principle : an owner can have 3 state :
//                1 : The owner is selected and no more highlightable
//                0 : The owner is NOT selected
//                -1: The owner is selected but stay highlightable (NEW)

// IMP230600      //GG Add protection on selection methodes
//                when nothing is selected

#define BUC60726        //GG_040900 When nothing is detected, 
//                Clear the last temporary stuff in any case

#define BUC60765  //GG_121000 Avoid to raise when the same selection 
//                is attached to several local context.

#define BUC60771  //GG_261000 Avoid to crash after closing a view
//                containing a selected entity and creating a new one.

#define BUC60774  //GG_261000 Returns right select status on
//                bounding-box selection type.

#define BUC60818  //GG_300101 Enable detection even if
//                SetAutomaticHilight(FALSE) has been used.

#define IMP300101       //GG Enable to use polygon highlighting

#define BUC60863  //GG_270301 Clear hilight soon after selecting or
//                      unselecting something in Local Context mode.

#define BUC60876  //GG_050401 Clear selection always even
//                if the current highlight mode is not 0.

#define BUC60953        //SAV_060701 For Select optimization. Selection by rectangle case.
                        // for single selection no optimization done.

#define IMP120701 //SZV made a shape valid for selection
//                when required.

#define IMP160701       //SZV Add InitDetected(),MoreDetected(),NextDetected(),

//                       methods

#define OCC138          //VTN Avoding infinit loop in AddOrRemoveSelected method.

#define OCC189          //SAV: 18/03/02 AIS_Selection::Objects() returns ListOfTransient
                        // instead of array.
