Zoom and Pan of DrawPane

Hi,

In SmartGwt showcase under Drawing, Zoom & Pan example we are able to zoom the image but i am not able to pan it ( I mean i am not able to click the image and drag it to see the zoomed portion).

Please let us know if I need to have any advacned browser to see this example.
