//! Describes a surface of linear extrusion ("extruded <br>
//! surface"), e.g. a generalized cylinder. Such a surface <br>
//! is obtained by sweeping a curve (called the "extruded <br>
//! curve" or "basis") in a given direction (referred to as <br>
//! the "direction of extrusion" and defined by a unit vector). <br>
//! The u parameter is along the extruded curve. The v <br>
//! parameter is along the direction of extrusion. <br>
//! The parameter range for the u parameter is defined <br>
//! by the reference curve. <br>
//! The parameter range for the v parameter is ] - <br>
//! infinity, + infinity [. <br>
//! The position of the curve gives the origin of the v parameter. <br>
//! The surface is "CN" in the v parametric direction. <br>
//! The form of a surface of linear extrusion is generally a <br>
//! ruled surface (GeomAbs_RuledForm). It can be: <br>
//! - a cylindrical surface, if the extruded curve is a circle, <br>
//!   or a trimmed circle, with an axis parallel to the <br>
//!   direction of extrusion (GeomAbs_CylindricalForm), or <br>
//! - a planar surface, if the extruded curve is a line <br>
//!   (GeomAbs_PlanarForm). <br>
//! Note: The surface of extrusion is built from a copy of <br>
//! the original basis curve, so the original curve is not <br>
//! modified when the surface is modified. <br>
//! Warning <br>
//! Degenerate surfaces are not detected. A degenerate <br>
//! surface is obtained, for example, when the extruded <br>
//! curve is a line and the direction of extrusion is parallel <br>
//! to that line. <br>
