        * gtk/gtkwidget.c: fixed a bunch of notifications, added
        reference counts around emissions where the widget is used afterwards.
        added freeze/thaws around multiple properties being notified.
        (_gtk_widget_get_aux_info): cleanups.

        * gtk/gtksettings.c (gtk_settings_install_property): provide
        default parsing functions for gdkcolor, enums and flags.

        * gtk/gtkwindow.[hc]: partially reverted patch from havoc,
        applied by owen.
        kept a flag in GtkWindowGeometryInfo to handle user
        resetting default sizes.
        cleaned up ZVT comments.
        bunch of assorted bug fixes, notification fixes.
        (_gtk_window_reposition): make this a really internal function.

        * gtk/testgtk.c: fixups.
