Syntax
public class SectorReshapingTool : Tool
Remarks

When a node is selected, this tool shows two handles for changing the angles of the sides of the sector and one handle for changing the radius.

This depends on there being three data properties, "Angle", "Sweep", and "Radius", that hold the needed information to be able to reproduce the sector.
