Previously the code assumed that coords of 0,0 were parent window coords, which was really broken. * gtk/gtkcontainer.c (gtk_container_get_focus_chain): fix warning * gdk/gdkwindow.h (GdkWindowHints): add GDK_HINT_USER_POS and GDK_HINT_USER_SIZE so we can set USSize and USPosition hints in gtk_window_parse_geometry() * gdk/x11/gdkwindow-x11.c (gdk_window_set_geometry_hints): support new USER_POS USER_SIZE hints
