NAME
       gluTessEndPolygon - delimit a polygon description

C SPECIFICATION
       void gluTessEndPolygon(GLUtesselator* tess);

PARAMETERS
       tess
	   Specifies the tessellation object (created with gluNewTess()).

DESCRIPTION
       gluTessBeginPolygon() and gluTessEndPolygon delimit the definition of a convex, concave, or self-intersecting polygon. Within each
       gluTessBeginPolygon()/gluTessEndPolygon pair, there must be one or more calls to gluTessBeginContour()/gluTessEndContour(). Within each
       contour, there are zero or more calls to gluTessVertex(). The vertices specify a closed contour (the last vertex of each contour is
       automatically linked to the first). See the gluTessVertex(), gluTessBeginContour(), and gluTessEndContour() reference pages for more
       details.

       Once gluTessEndPolygon is called, the polygon is tessellated, and the resulting triangles are described through callbacks. See
       gluTessCallback() for descriptions of the callback functions.

EXAMPLE
       A quadrilateral with a triangular hole in it can be described like this:

	   gluTessBeginPolygon(tobj, NULL);
	      gluTessBeginContour(tobj);
		 gluTessVertex(tobj, v1, v1);
		 gluTessVertex(tobj, v2, v2);
		 gluTessVertex(tobj, v3, v3);
		 gluTessVertex(tobj, v4, v4);
	      gluTessEndContour(tobj);
	      gluTessBeginContour(tobj);
		 gluTessVertex(tobj, v5, v5);
		 gluTessVertex(tobj, v6, v6);
		 gluTessVertex(tobj, v7, v7);
	      gluTessEndContour(tobj);
	   gluTessEndPolygon(tobj);

       In the above example the pointers, v1 through v7, should point to different addresses, since the values stored at these addresses will not
       be read by the tesselator until gluTessEndPolygon is called.
