    --          Redefines translation and treatment methods from inherited

    	---Purpose: Checks result of translation of IGES boundary entities
    	--          (types 141, 142 or 508).
	--          Checks consistency of 2D and 3D representations and keeps
	--          only one if they are inconsistent.
	--          Checks the closure of resulting wire and if it is not closed,
    	--          checks 2D and 3D representation and updates the resulting
    	--          wire to contain only closed representation.
	---Remark : If resulting representation will be 3D, some edges may still
    	--          contain pcurves which are consistent with 3D curves for the
	--          given edge.
