Mon Nov 16 15:10:33 1998  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtktext.c: Optimizations for moving point n
	places.
	(gtk-mailund-980718-0, Thomas Mailund Jensen <mailund@daimi.aau.dk>)

	* gtk/gtkfixed.c: Removed gtk_fixed_umap, which was
	broken. (GtkWidget's default unmap handler should work fine).
