	Bug 446355 – the parsing with pango_parse_markup is not coherent

	* pango/pango-markup.c (pango_parse_markup): Use
	pango_attr_list_insert() instead of pango_attr_list_change() as

	Bug 337593 – move glyph extents code (and cache) from
	pangocairo-*font.c into pangocairo-font.c

	* pango/pangocairo-fontmap.c:
	* pango/pangocairo-fcfontmap.c:

	and there is no reason to use it.

2007-06-04  Behdad Esfahbod  <[e-mail]>
