5.1.3 Generic functions

Generic Function: path-iterator-next (iterator)

Move the iterator to the next knot, and return
3 values: INTERPOLATION, KNOT and END-P. INTERPOLATION is the interpolation between the previous knot and the current one. For the first iteration, INTERPOLATION is usually the implicit straight line between the last knot and the first knot. KNOT and INTERPOLATION are null if the path is empty. END-P is true if the knot is the last on the path or if the path is empty.
