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 specified, 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.
