* A Surface is a 2-dimensional primitive and is composed
* of one or more surface patches. The surface patches are
* connected to one another.
* The orientation of the surface is positive ("up"). 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.
* 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. Its
* included surface patches describe the interior structure
* of the Surface.
