2000-09-28  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextview.c: Set up infrastructure to deal with lots of
	scrolling child windows, and draw focus rectangle properly.

	(gtk_text_view_buffer_to_window_coords):
	Coordinate transformation to deal with all these freaking windows
	and offsets
	(gtk_text_view_window_to_buffer_coords): transform the other way

	* gtk/testtext.c (create_buffer): Update to match Pango API change

	* gtk/gtktexttagtable.c (gtk_text_tag_table_foreach): Go over the
	anonymous tags
	(foreach_unref): don't emit remove signal from finalize, just
	set tag's parent to NULL
