Semi-finish widget embedding. Need guffaw scrolling to be implemented in

2000-11-20  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextview.c, gtk/gtktextlayout.c, gtk/gtktextchild.c,
	gtk/testtext.c: Semi-finish widget embedding. Need guffaw
	scrolling to be implemented in GDK to finish. Also, right now
	we just size_allocate all children on every layout change,
	which is pretty lame. Test commented out of testtext.c,
	until it works better.
