    ind >= 0: Hili Obj.
    ind = -1: gesamte Hili-Tabelle loeschen
    ind = -2: das zuletzt bearb. Elem. hiliten
    RetCod:
      -1      hidden object; not hilited ..
   
    Ein schon vorhandenes Objekt hiliten.
    ObjID merken fuer Redraw.
    Hier wird zusätzlich das DISP-Bit auf OFF gesetzt,
    um das Obj nicht doppelt zu zeichnen.
