Specifies the tessellation object (created with \%\f3gluNewTess\fP).
.SH DESCRIPTION
\%\f3gluTessBeginContour\fP and \%\f3gluTessEndContour\fP delimit the definition of a
polygon contour. Within each \%\f3gluTessBeginContour\fP/\%\f3gluTessEndContour\fP
pair, there can be zero or more calls to \%\f3gluTessVertex\fP. The vertices
specify a closed contour (the last vertex of each contour is automatically linked 
to the first).  See the \%\f3gluTessVertex\fP reference page for more details.
\%\f3gluTessBeginContour\fP can only be called between \%\f3gluTessBeginPolygon\fP and \%\f3gluTessEndPolygon\fP.
