Constructs an OrthogonalLinkReshapingTool and sets the name for the tool.
This stops the current reshaping operation and updates any link handles.
Compare two numbers to ensure they are almost equal. Used in this class for comparing coordinates of Points.
Create the segment dragging handles. There are two parts: one invisible handle that spans the segment, and a visible handle at the middle of the segment. These are inserted at the front of the adornment such that the normal handles have priority.
Change the route of the adornedLink by moving the segment corresponding to the current handle to be at the given Point.

The OrthogonalLinkReshapingTool class lets a user drag a tool handle along the link segment, which will move the whole segment.
