<p>A custom tool for rescaling an object.</p>
<div><p>Install the RescalingTool as a mouse-down tool by calling:
myDiagram.toolManager.mouseDownTools.add(new RescalingTool());</p>
<p>Normally it would not make sense for the same object to be both resizable and rescalable.</p>
<p>Note that there is no <code>Part.rescaleObjectName</code> property and there is no <code>Part.rescalable</code> property.
So although you cannot customize any Node to affect this tool, you can set
<a>RescalingTool.rescaleObjectName</a> and set <a>RescalingTool.isEnabled</a> to control
whether objects are rescalable and when.</p>
<p>If you want to experiment with this extension, try the <a href="../../extensionsJSM/Rescaling.html">Rescaling</a> sample.</p>
