Bug #919 - Replacement pango renderer (Neil Roberts)

	* clutter/clutter-backend.h:
	* clutter/clutter-backend.c:
	(clutter_backend_set_font_options),
	(clutter_backend_get_font_options): Add the ability to set
	the cairo_font_options_t* for the backend at construction
	time, so that backend implementations can have their own
	options.

	* clutter/clutter-color.c: Include pango/pango-attributes.h
	for the pango_color_parse() function.

	* clutter/clutter-label.c:
	(clutter_label_ensure_layout),
	(clutter_label_init), (clutter_label_set_text),
	(clutter_label_set_font_name), (clutter_label_set_ellipsize),
	(clutter_label_set_use_markup): Ensure that the cache is
	always primed when the Label changes; this makes sure that
	the cache is rebuilt outside the paint run, which should
	make the painting perform better especially on embedded
	devices.

	* clutter/clutter-entry.c:
	(clutter_entry_ensure_layout),
	(clutter_entry_init), (clutter_entry_set_text),
	(clutter_entry_set_font_name): Ditto as above.

	* clutter/clutter-private.h:
	* clutter/clutter-main.[ch]: Create the font-map inside the
	main context; add two new functions:

	  clutter_clear_glyph_cache()
	  clutter_set_use_mipmapped_text()

	that control the glyphs cache.

	* clutter/pango/Makefile.am:
	* clutter/pango/pangoclutter-fontmap.c:
	* clutter/pango/pangoclutter-private.h:
	* clutter/pango/pangoclutter-render.c:
	* clutter/pango/pangoclutter.h: Rewrite the Pango renderer
	using a PangoCairo context and saving the glyphs inside a
	more efficient cache.

	* configure.ac: Depend on pangocairo instead of pangoft2.
