Jonathan Blandford e4d1660042 Changed prototype to allow for getting the location of the cell relative
Thu Mar 15 18:22:44 2001  Jonathan Blandford  <jrb@redhat.com>

	* gtk/gtkcellrenderer.h: Changed prototype to allow for getting
	the location of the cell relative to its area.
	* gtk/gtkcell*: modified for above change
	* gtk/gtktreeview.c: modified for above change.

Wed Mar 14 13:58:32 2001  Jonathan Blandford  <jrb@redhat.com>

	* gtk/gtktreeview.c (gtk_tree_view_set_model): Ref the model.
	 (gtk_tree_view_finalize): actually unref the model.  Thanks to
	Jamie Strachan <frostfreek@yahoo.com> for noticing this error.
