	* pango/pango.def:
	* pango/pango-glyph.h:

	Bug 345511 – -no-undefined problem with new libtool

	* configure.in: Remove -no-undefined on non-Win32 systems.  That
	doesn't make any sense, and makes latest libtool not create shared
	libraries.

2006-06-21  Behdad Esfahbod  <[e-mail]>

	* autogen.sh: Just call gnome-autogen.sh.  The old autogen.sh had

	New functions pango_cairo_show_error_underline and
	pango_cairo_error_underline_path.

	* pango/pangocairo-render.c (_pango_cairo_do_glyph_string),
	(_pango_cairo_do_layout_line), (_pango_cairo_do_layout),
	(_pango_cairo_do_error_underline), (pango_cairo_show_glyph_string),
	(pango_cairo_show_layout_line), (pango_cairo_show_layout),
	(pango_cairo_show_error_underline),

2006-06-05  Hans Breuer  <[e-mail]>

	* pango/pangowin32-fontmap.c(pango_win32_font_map_init) : synthesize
	some italic variants for fonts no having them already. This fixes
	bug #343796 and for the italic case also bug #110521.

	* pango/pangocairo-win32font.c(compute_glyph_extents) : not only 
	handle PANGO_GLYPH_EMPTY but also PANGO_GLYPH_UNKNOWN_FLAG. 
	The latter is needed to have proper sizing of the "hex box" for 
	missing glyphs. It also stops cairo complaining about unknown glyphs.
	Fixes part of bug #343796.
	
	* pango/makefile.msc : create $(PRJ_TOP)\config.h.win32. (Not 
	changing in years does not necessarily mean it is not used)

	* pango/testfonts.c : make family_name survive 
	pango_font_description_free(), it is used later on
	
2006-06-02  Behdad Esfahbod  <[e-mail]>

	* pango/pango-utils.c (pango_find_base_dir): Don't g_return if text ==
	NULL and length == 0.

2006-05-31  Behdad Esfahbod  <[e-mail]>

	Bug 341138 – Using TTC font, Gtk2 programs begin to eating big memory
	and have many cpu usage.
	Patch from Yong Li.

	* pango/opentype/ftglue.c (_hb_ftglue_face_goto_table): TrueType table
	offsets are absolute, not relative.

2006-05-31  Behdad Esfahbod  <[e-mail]>

	Bug 336153 – Mark to mark positioning (Lookup Type 6) isn't correct
	when using MarkAttchmentType
	Patch from Tin Myo Htet.

	* pango/opentype/harfbuzz-gpos.c (Lookup_MarkMarkPos): Ignore marks
	of non-matchin attachment type.

2006-05-31  Behdad Esfahbod  <[e-mail]>

	* pango/pangocairo-font.c (_pango_cairo_font_get_hex_box_info): Set
	absolute_size, since we are using describe_with_absolute_size now...

2006-05-30  Behdad Esfahbod  <[e-mail]>

	Bug 333984 – pango_language_from_string improvements

	* pango/pango-utils.c (lang_equal), (lang_hash),
	(pango_language_from_string): Allow digits in language tags as per
	RFC-3066, and stop on first invalid char.  Previous
	pango_language_from_string ("en_US.UTF-8") was returning "en-usutf-",
	now it returns "en-us".
	
	* pango/pango-utils.c (pango_language_matches): Allow other common
	separators in the language list (colon, comma, and space).

2006-05-30  Behdad Esfahbod  <[e-mail]>

	center the underline in requested rectangle.

	* pango/pangocairo-render.c (pango_cairo_show_glyph_string): Remove
	unncessary renderer activation and cleanup.

2006-05-23  Tor Lillqvist  <[e-mail]>

	* pango/pangowin32.c (pango_win32_font_class_init): Initialize the
	describe_absolute method pointer correctly.
	(pango_win32_font_describe): Scale size to points which is what
	pango_font_description_set_size() wants. There has been several
	bugs opened around this issue, with more or less misleading
	guesses. See for instance #314114. Thanks to Behdad for finally
	noticing the real problem here.

2006-05-22  Behdad Esfahbod  <[e-mail]>

	Bug 342525 – With PangoFc and PangoWin32, approximate digit width is
	not what it says

	* pango/pangocairo-win32font.c (max_glyph_width),
	(create_metrics_for_context): Use max digit width instead of average.

	Reverted the following changes:

	* pango/pangofc-font.c (pango_fc_font_create_metrics_for_context):
	Likewise for PangoFc.  Compute average instead of max.
	(max_glpyh_with): Now unused, drop.

	* pango/pangowin32.c (pango_win32_font_get_metrics): Calculate
	average digit width correctly, not as max of the digit
	widths. (#342525) Note that this code doesn't really get much used
	currently (instead the code in pangocairo-win32font.c is used),
	fixed only for completeness.
	(max_glpyh_with): Now unused, drop.

2006-05-22  Behdad Esfahbod  <[e-mail]>

	* pango/pango-font.h, pango/fonts.c: New function

	* pango/pangofc-font.c (pango_fc_font_class_init),
	(pango_fc_font_describe_absolute),
	(pango_fc_font_create_metrics_for_context):
	* pango/pangowin32.c (pango_win32_font_class_init),
	(pango_win32_font_get_metrics), (pango_win32_font_describe),

	PangoFontClass->describe_absolute.
