3 * cone.h - header file for cones (cones, cylinders, rings, cups, tubes).
4 *
5 * Storage of arguments in the cone structure is a little strange.
6 * To save space, we use an index into the real arguments of the
7 * object structure through ca. The indices are for the axis
8 * endpoints and radii: p0, p1, r0 and r1.
