	* gdk/gdkpango.c (gdk_draw_layout_line): Draw underlines one pixel
	higher.

	* gtk/gtktextdisplay.c (render_layout_line): Take rise into
	account. Also, render rise, underline, background, etc. for
	pixbufs as well as text. Also, draw underlines one pixel higher.

	* gtk/gtktextlayout.c (gtk_text_layout_get_line_display): Add a
	PangoAttribute for the rise, so it gets drawn properly. Also,
	add the GtkTextAppearance attribute for pixbuf/widget segments
	as well; we should go ahead and have rise, underline, background,
	stipple work for those

	* gtk/gtktexttag.c: Rename "offset" property to "rise" to match
	Pango
