2008-09-30  Michael Natterer  <mitch@imendio.com>

	Bug 541009 – Get rid of separate subclasses for horizontal and
	vertical orientation:

	* gtk/Makefile.am
	* gtk/gtk.symbols
	* gtk/gtk.h
	* gtk/gtkorientable.[ch]: add new interface GtkOrientable which
	will be implemented by everything that can switch orientation.
