	Fixes #320665:

	* pango/pangocairo-fcfont.c: Use a simple, fixed-size cache to map
	gunichars to glyph indices within the font.  The cache is
	described in detail here:
	http://primates.ximian.com/~federico/news-2005-10.html#gtkfilechooser-profile-5
	(GlyphCacheEntry): new structure to hold a gunichar and a PangoGlyph.
	(struct _PangoCairoFcFont): Add a char_to_glyph_cache field.
	(pango_cairo_fc_font_get_glyph): Allocate the char_to_glyph_cache
	if needed.  We do it on demand because while many fonts will be
	alive at any one time (in order to cover the whole Unicode space),
	only very few of them will be actually accessed for glyph lookups.
	(pango_cairo_fc_font_get_glyph): Look up the gunichar in the
	cache, and replace the cache entry if necessary.
	(pango_cairo_fc_font_finalize): Free the char_to_glyph_cache.
