	* === Released 1.11.0 ===

	* configure.in: Version 1.11.0

	* NEWS: Updated.

2005-11-18  Behdad Esfahbod  <behdad@gnome.org>

	* pango/pango-layout.c (pango_layout_move_cursor_visually): Use the
	new support for negative offsets in g_utf8_pointer_to_offset.  So now,
	we simply do:
	offset += g_utf8_pointer_to_offset(text+oldindex, text+newindex),
	instead of doing
	offset = g_utf8_pointer_to_offset(text, text+index) as we did before.

2005-11-14  Behdad Esfahbod  <behdad@gnome.org>

	Updates from #320666:

	* pango/Makefile.am: Remove pango-easy-scripts-table.h.

2005-11-14  Behdad Esfahbod  <behdad@gnome.org>

	* examples/Makefile.am: Add X_CFLAGS to INCLUDES.  We normally are
	picking them up from XFT_CFLAGS, but we don't require Xft any more
	for X11. (#320576)

2005-11-14  Behdad Esfahbod  <behdad@gnome.org>

	* pango/break.c (pango_default_break): Remove g_utf8_strlen and

	no rtl strongs, and base dir is weak rtl.  Pointed out by Owen Taylor.

2005-11-11  Behdad Esfahbod  <behdad@gnome.org>

	* pango/pango-layout.c (pango_layout_get_alignment): Fix get/set

	letter_spacing adjustment on the item width. (#168593, Damon Chaplin)

	* pango/pango-markup.c (pango_parse_markup), pango/querymodules.c:
	Replace g_string_new ("") with g_string_new (NULL).

	* pango/pangoft2.c: Use g_malloc'ed memory for unknown FreeType2
	error, instead of static buffer.

2005-11-09  Behdad Esfahbod  <behdad@gnome.org>

	* modules/hebrew/.cvsignore, modules/khmer/.cvsignore,
	modules/tibetan/.cvsignore: Minor clean up and adjustment.

2005-11-07  Federico Mena Quintero  <federico@ximian.com>

	Fixes bug #320666:

	Instead of doing a bsearch() for every gunichar to map it to a
	PangoScript, use a precomputed table for the first 8192 code
	points.  Also, remember the last script that we computed on each
	invocation; this will also help CJK and the other scripts above
	U+2000.

	This table also holds information on whether the characters in it
	are paired characters.  We can use this to avoid doing the
	expensive get_pair_index() call most of the time.

	Many thanks to Matthias Clasen for his suggestions for this patch.

	* tools/gen-easy-scripts-table.c: New program to generate
	pango_easy_scripts_table.

	* tools/Makefile.am: Build gen-easy-scripts-table.

	* pango/pango-easy-scripts-table.h: New file with a mapping of the
	first 8192 Unicode characters to their corresponding scripts.  The
	table also says whether each character has a paired char or not.

	* pango/Makefile.am (libpango_1_0_la_SOURCES): Add pango-easy-scripts-table.h.

	* pango/pango-script-table.h: Remove everything below U+2000, and
	add a note to that effect.

	* pango/pango-script.c (pango_script_for_unichar_with_last_index):
	New function.  This is the old pango_script_for_unichar(), but it
	lets the caller keep around the computed index in
	pango_script_table.  This works under the assumption that a
	character is likely to be in the same script block as the
	preceding character in a string.
	(pango_script_for_unichar): First, do a quick check against the
	pango_easy_scripts_table.  Then, do the expensive check with
	pango_script_for_unichar_with_last_index().
	(pango_script_iter_next): If the character is within the easy
	script range, find out if it is a paired character by using
	PANGO_PAIRED_CHAR_FLAG.
	(struct _PangoScriptIter): Add a last_index_for_script_lookup
	field.  We use this to maintain the last-lookup index from
	pango_script_for_unichar_with_last_index().
	(pango_script_iter_next): If the character is not within the easy
	script range, use pango_script_for_unichar_with_last_index(), and
	store the index in the last_index_for_script_lookup field of the
	PangoScriptIter.

2005-11-04  Behdad Esfahbod  <behdad@gnome.org>

	* pango-config.in, pango.spec.in: Removed. Not used for a long time,
	and were out of date.

	* .cvsignore: Remove pango-config and pango.spec.

2005-11-04  Behdad Esfahbod  <behdad@gnome.org>

	* pango/break.c: Update to handle new line-breaking types in the
	Unicode 4.1 UAX#14. (#313907)

	* configure.in: Bump required glib version to 2.9.0.  Needed for
	above-mentioned line-breaking types.

	which was wrong.
	(compare_lang): Fix typo comparing a and a instead of a and b.

2005-11-04  Federico Mena Quintero  <federico@ximian.com>

	Fixes #320665:

	* pango/pangocairo-fcfont.c: Use a simple, fixed-size cache to map
	gunichars to glyph indices within the font.  The cache is
	described in detail here:
	http://primates.ximian.com/~federico/news-2005-10.html#gtkfilechooser-profile-5
	(GlyphCacheEntry): new structure to hold a gunichar and a PangoGlyph.
	(struct _PangoCairoFcFont): Add a char_to_glyph_cache field.
	(pango_cairo_fc_font_get_glyph): Allocate the char_to_glyph_cache
	if needed.  We do it on demand because while many fonts will be
	alive at any one time (in order to cover the whole Unicode space),
	only very few of them will be actually accessed for glyph lookups.
	(pango_cairo_fc_font_get_glyph): Look up the gunichar in the
	cache, and replace the cache entry if necessary.
	(pango_cairo_fc_font_finalize): Free the char_to_glyph_cache.

2005-11-04  Behdad Esfahbod  <behdad@gnome.org>

	* pango/pangocairo-fontmap.c: Use quarks for GObject data to improve
	performance.  (Patch from Federico Mena Quintero)

	* pango/modules.c (pango_module_load), pango/querymodules.c: Pass
	G_MODULE_BIND_LAZY to g_module_open.  (Pointed by John Rice)

2005-11-04  Behdad Esfahbod  <behdad@gnome.org>

	* pango/pangofc-font.c: Use macros for locking and unlocking fonts
	we know are valid to avoid redundant PANGO_IS_FC_FONT checks.
	(Review by Matthias Clasen)

2005-11-03  Behdad Esfahbod  <behdad@gnome.org>

	* docs/tmpl/main.sgml, pango/Makefile.am, pango/pango-context.c
	(itemize_state_init), pango/pango-utils.c, pango/pango-utils.h,
	pango/pangox.c (itemize_string_foreach), pango/mini-fribidi/*:
	Updated to FriBidi version 0.10.7 patched to handle UTF-8 directly.
	Moved pango_log2vis_get_embedding_levels to pango-utils.c instead
	of mini-fribidi.  (#317192, review by Matthias Clasen)

2005-11-03  Behdad Esfahbod  <behdad@gnome.org>

	* examples/pangoft2pgm.c, renderdemo.c, renderdemo.h: Added a --runs
	options, useful for profiling.  Misc cleanup, freeing memory. (from
	#170414)

2005-11-03  Behdad Esfahbod  <behdad@gnome.org>

	Patches from #170414.  Reviewed by Matthias Clasen.

	* pango/opentype/ftxgpos.c, pango/opentype/ftxgsub.c: Use call table
	to dispatch different lookup types.

	* pango/opentype/pango-ot-buffer.c, pango/opentype/pango-ot-ruleset.c:
	Small cleanup.

2005-10-02  Behdad Esfahbod  <behdad@gnome.org>

	* pango/pango-engine.h: Add const to gchar * members of structs.
	Shuts up gcc warnings. (#317676)

2005-09-09  Owen Taylor  <otaylor@redhat.com>

	* pango/pangocairo-render.c (pango_cairo_show_glyph_string): unset
	all part colors, since when drawing just a glyph string, 
	prepare_run() isn't called. (#315599, Choe Hwanjin)

	* pango/pango-renderer.c (pango_renderer_draw_layout_line): NULL
	out renderer->priv->line_state.

2005-09-25  Behdad Esfahbod  <behdad@gnome.org>

	* pango/mini-fribidi/fribidi_get_type.c: Removed.  Not needed since
	2003 or so!

2005-09-22  Tor Lillqvist  <tml@novell.com>

	* pango/pangocairo-win32font.c (_pango_cairo_win32_font_new): Move
	the calculation of dpi and size earlier. Use the size variable
	instad of isize when looking for a matching cached font. Isize was
	supposed to be the same as size anyway. (Actually it was the same
	only when LOGPIXELSY equalled 96 (which often is the default
	value), see below.)

	* pango/pangocairo-win32fontmap.c (pango_cairo_win32_font_map_init): 
	Set dpi to the LOGPIXELSY value instead of hardcoding 96.

	* pango/Makefile.am (libpangocairo_1_0_la_LIBADD): Need WIN32_LIBS
	now.

2005-09-14  Tor Lillqvist  <tml@novell.com>

	* pango/pangocairo-win32font.c: Use identical glyph extents
	cacheing as in pangocairo-fcfont.c. Huge performance improvement.

	* README.win32: Update.

2005-09-14  Tor Lillqvist  <tml@novell.com>

	* pango/pangocairo-win32font.c (struct _PangoCairoWin32Font): Have
	a list of metrics by language instead of just one metrics.

	(pango_cairo_win32_font_get_scaled_font): Use the name cwfont
	instead of cffont.

	(free_metrics_info, pango_cairo_win32_font_finalize): Free the
	metrics by language list.

	(create_metrics_for_context): New helper function. Approximate the
	character and digit widths correctly. (#314114)

	(pango_cairo_win32_font_get_metrics): Use the list of metrics by
	language. Call create_metrics_for_context() to measure metrics.
	
	(_pango_cairo_win32_font_new): Keep the PangoWin32Font objects in
	the PangoWin32Face::cached_fonts, like the pangowin32 backend
	does. 

	PangoWin32Face::cached_fonts isn't really a proper cache. It's a
	list with unbound length, one PangoWin32Font per size. Once there
	is cacheing in cairo this can be dropped presumably? What does the
	pangofc backend do? There are too many levels of cacheing going
	on: we have the stuff in pangowin32-fontcache.c (unused now with
	cairo), the PangoWin32FontMap::freed_fonts cache, and the
	PangoWin32::cached_fonts list.

	* pango/pangowin32-fontmap.c (pango_win32_fontmap_cache_remove,
	pango_win32_fontmap_cache_clear): Use GQueue API instead of
	manipulating pointers manually.

	* pango/pangowin32-private.h
	* pango/pangowin32.c: Move PangoWin32MetricsInfo to the private
	header file, as also pangocairo-win32font.c uses it.
	
2005-09-13  Tor Lillqvist  <tml@novell.com>

	* modules/basic/basic-win32.c: Drop unused font_cache variable and
	the call to pango_win32_font_map_for_display() used in its
	initialization, which caused an extra instance of
	PangoWin32FontMap to be created, and fonts enumerated an extra
	time.

2005-09-12  Jean Brefort  <jean.brefort@normalesup.org>

	* pango/pango-attributes.c: (pango_attr_list_splice): Fixed typo
	(#316054).

2005-09-11  Matthias Clasen  <mclasen@redhat.com>

	* pango/pangocairo-fontmap.c (free_context_info): Use g_free()
	to free g_new()-allocated data, otherwise the GLib memory profiler
	becomes very unhappy.

2005-09-05  Behdad Esfahbod  <pango@behdad.org>

	* pango/pango-layout.c (pango_layout_set_auto_dir): Fixed typo in 
	docs.

2005-08-29  Behdad Esfahbod  <pango@behdad.org>

	* pango/opentype/ottest.c, pango/opentype/disasm.c: Generate valid
	XML output.  Dump LookupFlag too.

2005-08-29  Behdad Esfahbod  <pango@behdad.org>

	* examples/cairoview.c: Set cairo font resolution.

	* tests/testboundaries.c: Remove unused Hangul Jamo macros.

2005-08-29  Behdad Esfahbod  <pango@behdad.org>

	* examples/HELLO.utf8: Add a few Arabic non-spacing marks to the
	example.  Put the line with Pango in Greek-Japanese back in.

2005-08-26  Behdad Esfahbod  <pango@behdad.org>

	* pango/break.c: Protect against future line-break type additions in
	glib Unicode module.

2005-08-25  Tor Lillqvist  <tml@novell.com>

	* pango/Makefile.am: Use pangocairo.def when linking libpangocairo
	on Windows, instead of relying on GNU ld auto-exporting all public
	symbols.

	* pango/pangocairo.def: Add missing entries. (#314420, Kazuki
	Iwamoto)

2005-08-24  Owen Taylor  <otaylor@redhat.com>

	* pango/pangocairo-render.c (draw_error_underline): convert
	from Pango units to doubles, fix some coordinate space problems
	that had previously been fixed in GTK+. (#313015, Luis Villa)
