don't create layout if we didn't have one (gtk_text_view_set_buffer):

2001-10-24  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextview.c (gtk_text_view_update_adjustments): don't
	create layout if we didn't have one
	(gtk_text_view_set_buffer): invalidate so we get the idle handlers
	as appropriate, avoids blanking the screen
	(gtk_text_view_invalidate): new function to do invalidation,
	containing old guts of invalidated_handler
