Constructs a shape parallel to the shape S, where
//! - S may be a face, a shell, a solid or a compound of these shape kinds;
//! - Offset is the offset value. The offset shape is constructed:
//! - outside S, if Offset is positive,
//! - inside S, if Offset is negative;
//! - Tol defines the coincidence tolerance criterion for generated shapes;
//! - Mode defines the construction type of parallels
//! applied to the free edges of shape S; currently, only one
//! construction type is implemented, namely the one where the free
//! edges do not generate parallels; this corresponds to the default
//! value BRepOffset_Skin;
//! - Intersection specifies how the algorithm must work in
//! order to limit the parallels to two adjacent shapes:
//! - if Intersection is false (default value), the intersection
//! is calculated with the parallels to the two adjacent shapes,
//! - if Intersection is true, the intersection is calculated by
//! taking all generated parallels into account; this computation method is
//! more general as it avoids some self-intersections generated in the
//! offset shape from features of small dimensions on shape S, however this
//! method has not been completely implemented and therefore is not
//! recommended for use;
//! - SelfInter tells the algorithm whether a computation
//! to eliminate self-intersections must be applied to the resulting
//! shape; however, as this functionality is not yet
//! implemented, it is recommended to use the default value (false);
//! - Join defines how to fill the holes that may appear between
//! parallels to the two adjacent faces. It may take values
//! GeomAbs_Arc or GeomAbs_Intersection:
//! - if Join is equal to GeomAbs_Arc, then pipes are generated
//! between two free edges of two adjacent parallels,
//! and spheres are generated on "images" of vertices;
//! it is the default value,
//! - if Join is equal to GeomAbs_Intersection, then the parallels to the
//! two adjacent faces are enlarged and intersected,
//! so that there are no free edges on parallels to faces.
//! Warnings
//! 1. All the faces of the shape S should be based on the surfaces
//! with continuity at least C1.
//! 2. The offset value should be sufficiently small to avoid
//! self-intersections in resulting shape. Otherwise these
//! self-intersections may appear inside an offset face if its
//! initial surface is not plane or sphere or cylinder, also some
//! non-adjacent offset faces may intersect each other. Also, some
//! offset surfaces may "turn inside out".
//! 3. The algorithm may fail if the shape S contains vertices where
//! more than 3 edges converge.
//! 4. Since 3d-offset algorithm involves intersection of surfaces,
//! it is under limitations of surface intersection algorithm.
//! 5. A result cannot be generated if the underlying geometry of S is
//! BSpline with continuity C0.
//! Exceptions
//! Geom_UndefinedDerivative if the underlying
//! geometry of S is BSpline with continuity C0.
