+// depending on the active window. In the GTK port, we had a hidden GtkMenuBar
+// object in each GtkWindow which existed only to be scrapped by the
+// libdbusmenu-gtk code. Since we don't have GtkWindows anymore, we need to
+// interface directly with the lower level libdbusmenu-glib, which we
+// opportunistically dlopen() since not everyone is running Ubuntu.
+//
+// This class is like the chrome's corresponding one, but it generates the menu
+// from menu models instead, and it is also per-window specific.
