13	13	* When one more node, part of the way, is selected, set the radius equal to the distance between the two selected nodes.
14	14	* When multiple ways are selected and they are connected to create a ring, align nodes by first computing an average center and by preserving relative angles of interconnection (e.g. of roads connecting to a roundabout) when regularizing the radius, and redistribute the other nodes in each arc.
	15	* When multiple ways are selected and they are not connected in a ring, the each of the selected closed ways will be circularized.
