gtk_window_get/set_attached_to() is a new API that allows for windows to be attached to a GtkWidget. The attachment is a logical binding between the toplevel window and the widget that generated it; this kind of information is currently used to propagate style information from the widget to the window, but is also useful e.g. for accessibility. https://bugzilla.gnome.org/show_bug.cgi?id=666103
