+
+ Bug 553573 – Add orientation API to GtkBox
+
+ * gtk/gtkbox.[hh]: implement the GtkOrientable interface and
+ swallow all code from GtkHBox and GtkVBox. Add gtk_box_new()
+ which takes a GtkOrientation argument. Also move the newly
+ added "spacing_set" boolean from struct GtkBox to the new
+ private struct.
+
+ * gtk/gtkhbox.[ch]
+ * gtk/gtkvbox.[ch]: remove all code except the constructor and
+ call gtk_orientable_set_orientation() in init().
+
+ * gtk/gtk.symbols: add gtk_box_new().
