The Douglas Peuker algorithm starts from reference points,
our implementation always takes start/end points as the natural
initial reference pair.
For closed linestrings (and polygon rings) I've been thinking a few
times that it would be nice to pick the reference points in a better
way (like the two furthest points) but never tried it.
