	* gtk/gtktextview.c (gtk_text_view_expose_event): propagate
	exposes to no window children not in the buffer window.
	(gtk_text_view_class_init): add move_focus bindings for Ctrl-Tab
	- is this the right way to do it?
	(gtk_text_view_focus): add focus method, just chains up for now,
	I'm not sure why the GtkContainer implementation doesn't work

	* gtk/gtktextbtree.c (_gtk_text_btree_insert_child_anchor): fill
	in the text line for the child anchor segment

	* tests/testtext.c (do_add_focus_children): add another test
	example (to put focusable buttons into the widget)
