   //! Adds to the bounding box B the surface S
   //! B is then enlarged by the tolerance value Tol.
   //! Note: depending on the type of curve, one of the following
   //! representations of the surface S is used to include it in the bounding box B:
   //! -   an exact representation if S is built from a plane, a
   //! cylinder, a cone, a sphere or a torus,
   //! -   the poles of the surface if S is built from a Bezier
   //! surface or a BSpline surface,
   //! -   the points of an approximation of the surface S in
   //! cases other than offset surfaces;
   //! -   in the case of an offset surface, the basis surface is first
   //! included according to the previous rules; then the
   //! bounding box is enlarged by the offset value.
   //! Warning
   //! Do not use these functions to add a non-finite surface to
   //! the bounding box B.
   //! If UMin, UMax, VMin or VMax is an infinite value B will become WholeSpace.
   //! S is an adapted surface, that is, an object which is an interface between:
   //! -   the services provided by a surface from the package Geom
   //! -   and those required of the surface by the computation algorithm.
