 When you tend to drag the bar of the PanZoomBar control too high (north
 off the control) or low (south off the widget), the control tends to do
 zoom into nonsense values. It is because the "zoomBarUp" method of the
 control does not check whether the "zoomLevel" computed value is inside
 the valid range of the current map zooms.

 Play with any map with the PanZoomBar, like

 zoom.html
