/* Menu
* #Keywords: action, zoom
*
* Demonstrates how to add a context menu to a custom widget
* and connect it with widget actions.
*
* The custom widget we create here is similar to a GtkPicture,
* but allows setting a zoom level for the displayed paintable.
*
* Our context menu has items to change the zoom level.
