Describes a surface of revolution (revolved surface).
//! Such a surface is obtained by rotating a curve (called
//! the "meridian") through a complete revolution about
//! an axis (referred to as the "axis of revolution"). The
//! curve and the axis must be in the same plane (the
//! "reference plane" of the surface).
//! Rotation around the axis of revolution in the
//! trigonometric sense defines the u parametric
//! direction. So the u parameter is an angle, and its
//! origin is given by the position of the meridian on the surface.
//! The parametric range for the u parameter is: [ 0, 2.*Pi ]
//! The v parameter is that of the meridian.
//! Note: A surface of revolution is built from a copy of the
//! original meridian. As a result the original meridian is
//! not modified when the surface is modified.
//! The form of a surface of revolution is typically a
//! general revolution surface
//! (GeomAbs_RevolutionForm). It can be:
//! - a conical surface, if the meridian is a line or a
//! trimmed line (GeomAbs_ConicalForm),
//! - a cylindrical surface, if the meridian is a line or a
//! trimmed line parallel to the axis of revolution
//! (GeomAbs_CylindricalForm),
//! - a planar surface if the meridian is a line or a
//! trimmed line perpendicular to the axis of revolution
//! of the surface (GeomAbs_PlanarForm),
//! - a toroidal surface, if the meridian is a circle or a
//! trimmed circle (GeomAbs_ToroidalForm), or
//! - a spherical surface, if the meridian is a circle, the
//! center of which is located on the axis of the
//! revolved surface (GeomAbs_SphericalForm).
//! Warning
//! Be careful not to construct a surface of revolution
//! where the curve and the axis or revolution are not
//! defined in the same plane. If you do not have a
//! correct configuration, you can correct your initial
//! curve, using a cylindrical projection in the reference plane.
