NAME
	  fgluTessBeginContour,	fgluTessEndContour - delimit a contour
	  description


     FORTRAN SPECIFICATION
	  SUBROUTINE fgluTessBeginContour( CHARACTER*8 tess )

	  SUBROUTINE fgluTessEndContour( CHARACTER*8 tess )


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

     DESCRIPTION
	  fgluTessBeginContour and fgluTessEndContour delimit the
	  definition of	a polygon contour. Within each
	  fgluTessBeginContour/fgluTessEndContour pair,	there can be
	  zero or more calls to	fgluTessVertex.	The vertices specify a
	  closed contour (the last vertex of each contour is
	  automatically	linked to the first).  See the fgluTessVertex
	  reference page for more details.  fgluTessBeginContour can
	  only be called between fgluTessBeginPolygon and
	  fgluTessEndPolygon.
