       // scroll vertically  a large picture
       var scrollPan = new zebkit.ui.ScrollPan(new zebkit.ui.ImagePan("largePicture.jpg"),
                                              "vertical");

       // scroll horizontally a large picture
       var scrollPan = new zebkit.ui.ScrollPan(new zebkit.ui.ImagePan("largePicture.jpg"),
                                              "horizontal");
