++	Bug 563356 – The input area of firefox and the blank width after text
++	in gnome-menu was stretched too wide, under pango-1.22.3
++
++	* docs/tmpl/fonts.sgml:
++	* pango/pango-impl-utils.h:
++	* pango/pangocairo-atsuifont.c
++	(pango_cairo_atsui_font_create_metrics_for_context):
++	* pango/pangocairo-win32font.c
++	(pango_cairo_win32_font_create_metrics_for_context):
++	* pango/pangofc-font.c (pango_fc_font_create_metrics_for_context):
++	For approximate_char_width calculation take each char's width into
++	account.  That is, do a weighted average instead of uniform average.
++	g_unichar_iszerowidth() chars count as 0, g_unichar_iswide() chars
++	count 2, and the rest count as 1.  Pretty much wcwidth() behavior.
++	See bug report for rationale.

++2008-11-28  Behdad Esfahbod  <behdad at gnome.org>
++
++	Bug 562574 – Pangocariowin32 is leaking every cairo font it ever
++	creates
++
++	* pango/pangocairo-atsuifont.c (pango_cairo_atsui_font_finalize):
++	* pango/pangocairo-win32font.c (pango_cairo_win32_font_finalize):
++	Finalize shared pangocairo font resources.  Oops!
++
++	* pango/pangocairo-font.c (_pango_cairo_font_private_finalize):
++	Protect against multiple calls to finalize.  This is practiced by the
++	pangocairo-fcfont when a font is shutdown and then finalized.
++
++2008-11-26  Behdad Esfahbod  <behdad at gnome.org>
++
++	* examples/cairotwisted.c (parametrize_path), (point_on_path):
++	Handle close_path correctly.
