@kai@typo.social If you move a point 100 units to the right, all corresponding points move 100 units to the right. Inserting points is done proportionally: if you insert a point at 30% between the two points of a line segment, it will be inserted at 30% in all corresponding line segments, regardless of their lengths. Curves are handled similarly, except it doesn't use the distance, but rather the "t" factor on the Bézier curve.
