🐛 Fix wrong extremity point in calculate-extremities for line-to

In the :line-to branch of calculate-extremities, move-p (the subpath
start point) was being added to the extremities set instead of from-p
(the actual previous point). For all line segments beyond the first one
in a subpath this produced an incorrect bounding-box start point.

The :curve-to branch correctly used from-p; align :line-to to match.
