 * This interface is equivalent to the GM_Surface specified in 

 * <a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=26012">ISO 19107</a>.

 * Surface is a subclass of {@link Primitive} and is the basis for 2-dimensional geometry. 

 * Unorientable surfaces such as the M�bius band are not allowed. 

 * <p/>

 * <p>

 * The orientation of a surface chooses an "up" direction through the choice of the upward normal, 

 * which, if the surface is not a cycle, is the side of the surface from which the exterior boundary 

 * appears counterclockwise. Reversal of the surface orientation reverses the curve orientation of 

 * each boundary component, and interchanges the conceptual "up" and "down" direction of the surface. 

 * </p>

 * <p>

 * If the surface is the boundary of a solid, the "up" direction is usually outward. 

 * For closed surfaces, which have no boundary, the up direction is that of the surface patches, 

 * which must be consistent with one another. 

 * </p>
