19 * NOTES: Use of this class by DP simplification algorithms
20 * makes it useless for a TaggedLineSegment to store copies
21 * of coordinates. Using pointers would be good enough here.
22 * We don't do it to avoid having to break inheritance from
23 * LineSegment, which has copies intead. Wheter LineSegment
24 * itself should be refactored can be discussed.
