class Transformation from PGeom2d inherits Persistent from Standard

        ---Purpose :  The    class Transformation  allows   to  create
        --         Translation, Rotation,   Symmetry,     Scaling  and
        --         complex transformations obtained by  combination of
        --         the  previous elementary   transformations.     The
        --         restriction to  these basic  transformations allows
        --         us to be sure that   an object  will never   change
        --         nature.
