This sample demostrates the use of the ZoomSlider extension.
When using the ZoomSlider extension, the diagram Div must always be a direct child
of a Div using <code>position: relative</code> or <code>position: absolute</code>,
so that the ZoomSlider HTML DOM can be positioned correctly relative to the Diagram Div.
