This adds gtk_widget_get/set_opacity, as well as a GtkWidget.opacity property. Additionally it deprectates gtk_window_get/set_opacity and removes the GtkWindow.opacity property (in preference for the new identical inherited property from GtkWidget, which should be ABI/API compat). The implementation is using the new gdk_window_set_opacity child window support for windowed widgets, and cairo_push/pop_group() bracketing in gtk_widget_draw() for non-window widgets. https://bugzilla.gnome.org/show_bug.cgi?id=687842
