---Purpose: A framework to define sensitive 3D points.

---Purpose: Constructs a sensitive point object defined by the
-- owner OwnerId and the point Point.

---Level: Public
---Purpose:Converts the stored 3D point into a 2D point according
-- to <aProjector> ; this method is called by the selection Manager.

---Level: Public
---Purpose: stores in <aresult> the 2D sensitive box which represents
-- the point area in the selection process.

returns Boolean
is redefined static;
---Level: Public
---Purpose: returns true if the X,Y position matches the point
-- else gives the distance between them.
