                ConnectionWidget.controlPointCutDistance property allows you to specify a distance where the path should be cut

                at each control point.

		See test.widget.ConnectionWidgetCutDistanceTest for example.

<p>

There is a <code>controlPointCutDistance</code> property. If set to positive number (by default 0), then the connection path is cut at each control point to make smoother corners. The smooth corners are not used during calculation whether a mouse-cursor hits the path.
