	* libnautilus-extensions/nautilus-scalable-font.h:
	Change api to accept a string with embedded new lines instead of
	an array of strings.  This simplifies many things.

	* libnautilus-extensions/nautilus-label.c:
	(nautilus_label_initialize), (nautilus_label_destroy),
	(render_buffer_pixbuf), (label_recompute_line_geometries):
	Update for NautilusScalalbleFont api changes.  No longer need to
	tokenize the text string.  we can feed the string to the rendering
	api as is.

	* librsvg/rsvg-ft.c: (rsvg_ft_render_string):
	* librsvg/rsvg-ft.h:
	Change the string to glyph rendering api to accept the string
	length rather than computing it.  This makes it possible to feed
	it arbitrary lengths.

	* librsvg/rsvg.c: (rsvg_text_handler_characters):
	* librsvg/test-ft-gtk.c: (draw_line):
	* librsvg/test-ft.c: (main):
	Update for api changes.

	* test/test-nautilus-font.c: (main):
	Update test to use text lines drawing api.

	* test/test-nautilus-label.c:
	(alpha_background_color_value_changed_callback), (main):
	Update test for 2 new lines in a row.
