fix this to be sane

2000-12-04  Havoc Pennington  <hp@redhat.com>

	* gtk/gtkpaned.c (gtk_paned_expose): fix this to be sane

	* gtk/gtkvpaned.c (gtk_vpaned_expose): Add an expose handler

	* gtk/gtkhpaned.c (gtk_hpaned_expose): Add an expose handler

	* gtk/gtknotebook.c (gtk_notebook_draw_tab): put in a temporary
	hack to avoid infinite loops (queue draw instead of draw) -
	Owen has more appropriate fixes in a branch he'll check in later.

	* gtk/gtktextiter.c (gtk_text_iter_ends_line): handle paragraph
	separator, CR, and CRLF as line ends

	* gtk/gtktextbtree.c (gtk_text_btree_insert): on insertion, break
	into lines using pango_find_paragraph_boundary(); other bits of
	the widget are still going to be broken if the boundary isn't '\n'
	though
