	Bug 478914 – Use something invalid instead of '?' when validating
	input text

	* pango/pango-layout.c (pango_layout_set_text): Set invalid input
	bytes to -1, which gives a unichar value of -1, and eventually a
	glyph value of -1, aka PANGO_GLYPH_INVALID_INPUT.

	(pango_font_get_metrics), (pango_font_get_font_map):

	* pango/shape.c (pango_shape):
	Render PANGO_GLYPH_INVALID_INPUT to a single-width box with a cross
	inside.  Also cleanup spewed warnings and warn at the source, where

	a NULL font.

	* 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  <[e-mail]>

	* 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.)

	* docs/tmpl/main.sgml:

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* 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.

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

	* 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!

	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...
