* gtk/gtktextview.c (changed_handler): Call scroll_calc_now()
	unconditionally, since we may need to update the horizontal
	scrollbars even if the height didn't change.

	* gtk/gtktextlayout.c (add_preedit_attrs): Always get
	the extra attrs, since some of them affect size.

	* gtk/gtktextdisplay.c (gtk_text_layout_draw): Factor in
	x_offset correctly.
