NAME
       gleScrew	- Draws	screw-type shapes.

SYNTAX
       void gleScrew (int ncp,
		      gleDouble	contour[][2],
		      gleDouble	cont_normal[][2],
		      gleDouble	up[3],
		   gleDouble startz,
		   gleDouble endz,
		   gleDouble twist);

ARGUMENTS
       ncp	 number	of contour points

       contour	 2D contour

       cont_normal
		 2D contour normals

       up	 up vector for contour

       startx	 start of segment

       endz	 end of	segment

       twist	 number	of rotations

DESCRIPTION
       Draws  screw-type shapes. Takes a contour, and extrudes it along	the z-
       axis, from a start z value of startz to an end z-value of endz.	During
       the extrusion, it will spin the contour along  the  contour  origin  by
       twist degrees.
