2007-11-29  Behdad Esfahbod  <behdad@gnome.org>

	* example/cairo*.c: Add some documentation.

2007-11-29  Behdad Esfahbod  <behdad@gnome.org>

	Bug 485536 – underline_position can be zero

	* pango/pango-utils.c (pango_cairo_quantize_line_geometry):
	Document that returned position may be zero.

	* pango/pangocairo-win32font.c
	(pango_cairo_win32_font_create_metrics_for_context):
	* pango/pangofc-font.c (get_face_metrics):
	Handle case of underline_position==0 after rounding.

2007-11-29  Behdad Esfahbod  <behdad@gnome.org>

	Bug 500549 – pangocairo.h should include pango.h and cairo.h

	* pango/pangocairo.h: #include <pango/pango.h>

2007-11-23  Behdad Esfahbod  <behdad@gnome.org>

	* docs/check.docs: Make it reusable by not hardcoding "pango".

2007-11-23  Behdad Esfahbod  <behdad@gnome.org>

	* pango/opentype/harfbuzz-impl.c: Remove unused macro.

2007-11-18  Behdad Esfahbod  <behdad@gnome.org>

	* docs/Makefile.am: Replace GNU-specific syntax with more general one.

2007-11-16  Tor Lillqvist  <tml@novell.com>

	* pango/pango-utils.c (handle_alias_line): Factor out the common
	code from read_builtin_aliases() and read_alias_file(). (#492517)

2007-11-09  Behdad Esfahbod  <behdad@gnome.org>

	* pango/Makefile.am: Include ATSUI included modules.

2007-11-08  Behdad Esfahbod  <behdad@gnome.org>

	Bug 495091 – pango-utils.c:variable is declared at middle of block

	* pango/pango-utils.c (read_builtin_aliases): Move variable
	declaraction before code.

2007-11-07  Behdad Esfahbod  <behdad@gnome.org>

	* pango/opentype/*: And some more.

2007-11-07  Behdad Esfahbod  <behdad@gnome.org>

	* pango/opentype/*: Some more cleanup and merging.

2007-11-05  Behdad Esfahbod  <behdad@gnome.org>

	* tools/gen-script-for-lang-new.c (scripts_for_lang), (main):
	Update to new propsed language enumeration API for fontconfig.

2007-11-02  Tor Lillqvist  <tml@novell.com>

	* pango/pango-utils.c (read_builtin_aliases, pango_load_aliases):
	On Windows store the default aliases file in a string
	array. (#492517)

	Compared to the pango.aliases file as distributed with my most
	recent Windows builds there are some changes: Add the DejaVu fonts
	as the first ones listed for the generic sans, serif and mono font
	names. Use Tahoma instead of Arial for sans, and Georgia instead
	of Times New Roman for serif (to be used if the DejaVu fonts
	aren't present). Add Arial Unicode MS (a font with quite large
	coverage that comes with MS Office and thus is often
	available). Add Sylfaen (the Armenian and Georgian font bundled
	with Windows).

	When using the MS-Windows theme the font used by GTK+ will the
	system UI one. Both fonts typically used as system fonts, Tahoma
	(on XP) and Segoe UI (on Vista), are aliased here.

	* pango/pango-utils.c (read_alias_file): Accept also a quoted
	string for the left-hand side of an aliases file line. This is to
	enable aliasing fonts with spaces in their name, like "Segoe UI"
	which is the default system font on Vista. (#492504) (With the
	above built-in default aliases lists, no actual pango.aliases file
	is longer required on Windows for non-Latin script support,
	though.)

2007-10-30  Behdad Esfahbod  <behdad@gnome.org>

	* docs/pango-sections.txt:
	* docs/tmpl/main.sgml:
	* docs/tmpl/vertical.sgml:
	Improve vertical docs.

2007-10-29  Behdad Esfahbod  <behdad@gnome.org>

	* === Released 1.19.0 ===

	* configure.in: Version 1.19.0

	* NEWS: Updated.

2007-10-28  Behdad Esfahbod  <behdad@gnome.org>

	* pango/pango-script-lang-table.h:
	* tools/gen-script-for-lang-new.c:
	Sort scripts based on frequency.

	* tools/Makefile.am: Don't build anything by default.

2007-10-26  Murray Cumming  <murrayc@murrayc.com>

	* docs/pango_markup.sgml: Adds a link to 
	pango_font_description_from_string() so that the font_desc 
	attribute is not so mysterious. Bug #490661.

2007-10-26  Behdad Esfahbod  <behdad@gnome.org>

	* tools/Makefile.am:
	* tools/gen-script-for-lang-new.c:
	Functional dup of gen-script-for-lang that uses FcGetLangs() and
	FcCharSetForLang() instead of parsing .orth files.

2007-10-26  Behdad Esfahbod  <behdad@gnome.org>

	* pango/pango-script-lang-table.h: Update for fontconfig-2.4.91.

2007-10-25  Behdad Esfahbod  <behdad@gnome.org>

	* pango/pangofc-fontmap.c (pango_fc_font_map_get_patterns):
	Call FcFontSetDestroy() instead of FcFontSetSortDestroy().
	These days they are the same, but previously the latter was
	not freeing the actual patterns.  But we don't need the
	sort patterns, so this retroactively fixes a leak in older
	versions!

2007-10-25  Behdad Esfahbod  <behdad@gnome.org>

	* pango/opentype/*: New header file harfbuzz-global.h.  Rename
	FT_* int types to HB_* types.

	* pango/opentype/harfbuzz-gpos-private.h:
	* pango/opentype/harfbuzz-gsub-private.h:
	Add commented-out dummy struct for Extension lookups.

2007-10-24  Behdad Esfahbod  <behdad@gnome.org>

	Bug 478865 – Drastically reduce number of PangoFont objects created
	for rotating text

	* pango/pangofc-fontmap.c (fontset_hash_key_hash),
	(get_scaled_size), (pango_fc_font_map_get_patterns):
	Use a Pango-unit int for scaled-size instead of double.
	Merges even more queries...

	(fontset_hash_key_hash), (fontset_hash_key_copy),

	Only keep scaled-size in fontset hash, instead of unscaled-size
	and context matrix.

2007-10-24  Behdad Esfahbod  <behdad@gnome.org>

	notification purposes.

	* pango/pango-font.h: Make PANGO_GLYPH_EMPTY, PANGO_GLYPH_UNKNOWN_FLAG,

	defined for backend/engine implementations.

	(pango_ot_buffer_new), (pango_ot_buffer_destroy):

	* pango/opentype/*: HarfBuzz hacking to:

	  - Rename last remaining FT_Err stuff to HB_Err.

	  - Fix a couple invalid table paths to be permissive so
	    fonts work better.  Particularly GDEF table for Nafees
	    Nastaliq is loaded and works great now.

	  - Optimize harfbuzz buffer to not copy/swap for simple
	  one-to-one and "copy" GSUB operations.

	* pango/pango-ot*: Update to FT_Err to HB_Err renaming.
