NAME
       gleSuperExtrusion - Extrude arbitrary 2D contour along arbitrary 3D path, specifying local affine transformations.

SYNTAX
       void gleSuperExtrusion (int ncp,
		       gleDouble contour[][2],
		       gleDouble cont_normal[][2],
		       gleDouble up[3],
		       int npoints,
		       gleDouble point_array[][3],
		       float color_array[][3],
		 gleDouble xform_array[][2][3]);

ARGUMENTS
       ncp	 number of contour points

       contour	 2D contour

       cont_normal
		 2D contour normals

       up	 up vector for contour

       npoints	 numpoints in poly-line

       point_array
		 polyline vertices

       color_array
		 colors at polyline verts

       xform_array
		 2D contour affine transforms

DESCRIPTION
       Extrude	arbitrary 2D contour along arbitrary 3D path, specifying local affine transformations. As the contour is extruded, the affine will
       be applied to the points in the contour.

       The argument "contour" specifies the 2D contour to be extruded, while the argument "point_array" specifies the path along which to extrude.
       The vector "up" defines the orientation of the contour y-axis in real 3D space.

       Note  that  neither the very first segment, nor the very last segment are drawn. The first and last segments serve only to define the angle
       of the join at the very ends of the polyline. Thus, to draw one segment, three must be specified. To draw two segments, four must be speci-
       fied, etc.

       The normal array may be NULL. If it is, normal vectors will NOT be automatically generated, and the object will look terrible when lit.

       The  color array may be NULL. If NULL, the current color is used. If not NULL, the glColor3f() routine is used to set the color; therefore,
       specifying the glColorMaterial() subroutine before this primitive can be used to set diffuse, specular, ambient, etc. colors.
