make the orientation flipping much simpler by using the GtkOrientable

Browse Source 
2009-02-19  Michael Natterer  <mitch@imendio.com>

	* gtk/gtkscalebutton.c: make the orientation flipping much simpler
	by using the GtkOrientable features of the involved widgets:

	(gtk_scale_button_init): create the frame, box and scale here,
	they never need to be recreated because they implement GtkOrientable.

	(gtk_scale_button_constructor): remove their construction here.

	(gtk_scale_button_set_orientation): don't destroy and re-create
	anything. Instead, simply set the orientation of the above created
	widgets and fiddle a bit with the "plus" and "minus" buttons'
	packing and the scale's "inverted" state.

	Remove separate internal GtkScaleButtonHScale and
	GtkScaleButtonVScale subclasses and simply have a
	GtkScaleButtonScale directly inherited from GtkScale.
