* 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.
