Matthias Clasen fe842a5496 Make GtkCellView public, since people seem to have uses for it, it is 
2004-07-19  Matthias Clasen  <mclasen@redhat.com>

	Make GtkCellView public, since people seem to have uses for it,
	it is clean API and we were just conservative in not making it
	public initially. At the same time, get rid of GtkCellViewMenuItem,
	which doesn't have any function which can't be served by a
	GtkMenuItem with a GtkCellView child.

	* gtk/gtk.h: Include gtkcellview.h

	* gtk/Makefile.am (gtk_public_h_sources):

	* gtk/Makefile.am (gtk_private_h_sources):
	(gtk_c_sources): Remove gtkcellviewmenuitem.[hc]
	* gtk/gtkcombobox.c: Replace all uses of GtkCellViewMenuItem by
	GtkMenuItem with a GtkCellView child.

	* gtk/gtkcellviewmenuitem.[hc]: Removed.
