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

    ---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.

    ---Purpose: returns true if the X,Y position matches the point
    --          else gives the distance between them.
