			<tt>gluTessBeginContour</tt> and <tt>gluTessEndContour</tt> delimit the definition of a polygon
			contour. Within each <tt>gluTessBeginContour</tt>/<tt>gluTessEndContour</tt> pair, there can be
			zero or more calls to <a href="gluTessVertex.3G.xml"><tt>gluTessVertex</tt></a>. The vertices specify a closed contour
			(the last vertex of each contour is automatically linked to the first). See the <a href="gluTessVertex.3G.xml"><tt>gluTessVertex</tt></a> reference page for more details. <tt>gluTessBeginContour</tt>
			can only be called between <a href="gluTessBeginPolygon.3G.xml"><tt>gluTessBeginPolygon</tt></a> and <a href="gluTessEndPolygon.3G.xml"><tt>gluTessEndPolygon</tt></a>.
