A meta-layer which contains one single feature, namely the BBOX of the current map view. This can be used to trigger
special actions. If a popup is defined for this layer, this popup will be accessible via an extra button on screen.

The icon on the button is the default icon of the layer, but can be customized by detecting 'button=yes'.
