Draw polycone, specified as a polyline with radii.
</p><p>
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.
</p><p>
The color array may be <tt>NULL</tt>. If <tt>NULL</tt>, the current color is used. If not
<tt>NULL</tt>, the <a href="glColor.3G.xml"><tt>glColor3f</tt></a> routine is used to set the color;
therefore, specifying the <a href="glColorMaterial.3G.xml"><tt>glColorMaterial</tt></a> subroutine before this primitive can
be used to set diffuse, specular, ambient, etc. colors.
</p><p>
By default, the cross-section of the cylinder is drawn as a 20-sided polygon. This number can be changed using the
<a href="gleSetNumSides.3GLE.xml"><tt>gleSetNumSides</tt></a> routine.
