Taper-adding transformations on a shape.
//! The resulting shape is constructed by defining one face
//! to be tapered after another one, as well as the
//! geometric properties of their tapered transformation.
//! Each tapered transformation is propagated along the
//! series of faces which are tangential to one another and
//! which contains the face to be tapered.
//! This algorithm is useful in the construction of molds or
//! dies. It facilitates the removal of the article being produced.
//! A DraftAngle object provides a framework for:
//! - initializing the construction algorithm with a given shape,
//! - acquiring the data characterizing the faces to be tapered,
//! - implementing the construction algorithm, and
//! - consulting the results.
//! Warning
//! - This algorithm treats planar, cylindrical and conical faces.
//! - Do not use shapes, which with a draft angle added to
//! a face would modify the topology. This would, for
//! example, involve creation of new vertices, edges or
//! faces, or suppression of existing vertices, edges or faces.
//! - Any face, which is continuous in tangency with the
//! face to be tapered, will also be tapered. These
//! connected faces must also respect the above criteria.

//! F is a face, which belongs to the initial shape of this algorithm or
//! to the shape loaded by the function Init.
//! Only planar, cylindrical or conical faces can be tapered:
//! - If the face F is planar, it is tapered by inclining it
//! through the angle Angle about the line of intersection between the
//! plane NeutralPlane and F.
//! Direction indicates the side of NeutralPlane from which matter is
//! removed if Angle is positive or added if Angle is negative.
//! - If F is cylindrical or conical, it is transformed in the
//! same way on a single face, resulting in a conical face if F
//! is cylindrical, and a conical or cylindrical face if it is already conical.
//! The taper-adding transformation is propagated from the face F along
//! the series of planar, cylindrical or conical faces containing F,
