 // This is the GTK implementation of the bookmark bubble, the dialog box
 // presented to create or edit a bookmark.  There can only ever be a single
 // bubble open, so the class presents only static methods, and handles the
 // singleton behavior for you.  It also handles the object and widget
 // lifetimes, destroying everything and possibly committing any changes when
 // the bubble is closed.
