This sample demonstrates the OrthogonalLinkReshapingTool that is defined in its own file, as <a href="OrthogonalLinkReshapingTool.js">OrthogonalLinkReshapingTool.js</a>.
This tool allow users to shift the sections of orthogonal links in addition to resegmenting them.
The Diagram's <a>ToolManager.linkReshapingTool</a> and link template's <a>Part.reshapable</a> properties must be set to use this tool.
The <a>Link.resegmentable</a> property can still optionally be used.
