Does not attempt to handle clusters in a Uniscribe- or HarfBuzz-compatible way;
just returns the original string indexes that CT maintains. These may even be
out-of-order in the case of reordrant glyphs.
Also remove shaper_options argument to hb_shape_full(). That was
unused and for "future". Let it go.
More shaper API coming in preparation for plan/planned API.
Remove hb_ft_get_font_funcs() as it cannot be used by the user anyway.
Add hb_ft_font_set_funcs(). Which will make the font internally use
FreeType. That is, no need for the font to have created using the
hb-ft API. Just create using hb_face_create()/hb_font_create() and
then call this on the font (after having set font scale). This
internally creates an FT_Face and attached to the font.
hb_shape() now accepts a shaper_options and a shaper_list argument.
Both can be set to NULL to emulate previous API. And in most situations
they are expected to be set to NULL.
hb_shape() also returns a boolean for now. If shaper_list is NULL, the
return value can be ignored.
shaper_options is ignored for now, but otherwise it should be a
NULL-terminated list of strings.
shaper_list is a NULL-terminated list of strings. Currently recognized
strings are "ot" for native OpenType Layout implementation, "uniscribe"
for the Uniscribe backend, and "fallback" for the non-complex backend
(that will be implemented shortly). The fallback backend never fails.
The env var HB_SHAPER_LIST is also parsed and honored. It's a
colon-separated list of shaper names. The fallback shaper is invoked if
none of the env-listed shapers succeed.
New API hb_buffer_guess_properties() added.
Nothing functional in there yet.
So far, we're parsing IndicSyllabicCategory.txt and IndicMatraCategory.txt
fils from Unicode Character Database and store them in an array to be used
by the shaper. Also hooked up the shaper, but it does not do anything
right now.

fl->ApplyOrder. (Found by Behdad)
2005-04-12 Tor Lillqvist <tml@novell.com>

libpango_ot_la_LIBADD to actually make libpango-ot.la link with
it.

Sun Feb 29 09:25:13 2004 Owen Taylor <otaylor@redhat.com>
Rework opentype interfaces and other changes to make GPOS
work for Arabic. (Most of #117282, #121060)
* pango/opentype/otlbuffer.[ch]: OTL_Buffer that
acts as a replacement for the separate GSUB and
GPOS string structures and hides many of the internal
details.
* pango/opentype/ftxgsub.[ch] pango/opentype/ftxgpos.[ch]:
Adapt to OTL_Buffer.
* pango/opentype/ftxgpos.c: Redo handling of cursive
chains so that it actually works.
* pango/pango-ot.h pango/opentype/pango-ot-buffer.c:
Pango wrapper around OTL_Buffer.
* pango/pango-ot.h pango/pango-ot-ruleset.c pango/pango-ot-buffer.c:
Split pango_ot_ruleset_shape() into pango_ot_ruleset_substitute(),
pango_ot_ruleset_position(), make them act on
PangoOTBuffer, add a separate pango_ot_buffer_output()
which does the default positioning and writes to a
PangoGlyphString.
* modules/arabic/arabic-fc.c modules/indic/indic-fc.c
modules/indic/mprefixups.[ch]: Adapt to new OpenType
interfaces; add GPOS features for Arabic.
* pango/opentype/pango-ot-info.c: Don't derive class information
from Unicode properties for Arabic presentation forms,
let the shaping process derive the properties.
2003-03-11 James Henstridge <james@daa.com.au>
* autogen.sh: make similar changes to the ones on glib head (call
gtk-docize, etc).
* configure.in: move some calculations into M4 macros, rather than
calculating them when configure runs.
Use AC_HELP_STRING where appropriate.
Replace gtk-doc checks with a call to GTK_DOC_CHECK.
Replace AC_OUTPUT_COMMANDS() call with a number of calls to
AC_CONFIG_COMMANDS (once per created file).
Get rid of the "chmod +x pango-config" bit, because there is no
pango-config anymore.
* Makefile.am: get rid of custom distcheck rule, and set
DISTCHECK_CONFIGURE_FLAGS, which is equivalent.
Use += to select which .pc files to install.
* pango/Makefile.am: Add rules to rebuild module-defs* files, and
remove them on clean.
Reorder so that rules related to each individual library are next
to each other.
Use BUILT_SOURCES for built sources.
* pango/opentype/Makefile.am: don't use STRIP_BEGIN/STRIP_END.
* modules/*/Makefile.am: simplify module makefiles through use of
+=, and regularise them a bit (fixed a few bugs in the process).
* docs/Makefile.am: remove common rules, and instead include
gtk-doc.make.
* examples/Makefile.am: add pango.modules to CLEANFILES.
* tests/Makefile.am: remove temporary files on clean.
Mon Feb 17 13:06:39 2003 Owen Taylor <otaylor@redhat.com>

pango/pangoxft-fontmap.c: Add caching of fontsets
(#104495, initial patch and review by Soeren Sandmann)
* pango/pangofc-fontmap.cI pango/pangoft2-fontmap.c
pango/pangoxft-fontmap.c pango/pangoft2-private.h
pango/pangoxft-private.h: Remove cache of recently freed
fonts; not necessary now that we cache fontsets.
* pango/pangofc-fontmap.cI (pango_fc_pattern_set_free):
Rename from pango_fc_font_set_free to reflect
what it actually does.
* pango/pangofc-fontmap.cI pango/pangoft-fontmap.c
pango/pangoxft-fontmap.c: Combine clear-the-cache
functions; we didn't need separate clear-the-font-cache
and clear-the-pattern-cache functions.
2002-11-26 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* configure.in: Do not add GLIB_CFLAGS to CFLAGS.
* docs/Makefile.am, examples/Makefile.am,
modules/arabic/Makefile.am, modules/basic/Makefile.am,
modules/hangul/Makefile.am, modules/hebrew/Makefile.am,
modules/indic/Makefile.am, modules/tamil/Makefile.am,
modules/thai/Makefile.am, pango/Makefile.am,
pango/mini-fribidi/Makefile.am, pango/opentype/Makefile.am:
Instead add $(GLIB_CFLAGS) directly to INCLUDES (GTKDOC_CFLAGS for
docs/Makefile.am). Also some cosmetic line wrapping and
reindentation.
2002-09-24 Tor Lillqvist <tml@iki.fi>
* pango/opentype/pango-ot.def: Remove. Not used. (A static library
is built here. Exported entries are in ../pangoft2.def.)
* pango/opentype/Makefile.am (EXTRA_DIST): Remove from here, too.
2001-09-19 Havoc Pennington <hp@redhat.com>
* pango/opentype/fterrcompat.h: header to abstract the difference
between FreeType 2.0.3 and 2.0.4 error codes, based on the
configure check.
* configure.in: check for the tterrors.h header in FreeType 2.0.3,
and define HAVE_FREETYPE_2_0_3 if we have it
Tue Sep 18 15:47:08 2001 Owen Taylor <otaylor@redhat.com>
* configure.in (PANGO_MINOR_VERSION): Up to 0.19.

pango/pangoxft-fontmap.c pango/pangoft-fontmap.c pango/pango-context.[ch]
pango/pangox-fontmap.c: Add new PangoFontFace and PangoFontFamily
object types, and change the font listing API to list faces and
families, instead of face names and font descriptions.
* pango/pango-font.h pango/fonts.c: Make PangoFontDescription
an opaque heap-allocated structure, add accessors and
convenience functions.
* pango/pango-font.h pango/pango-private.h: Make PangoFontMetrics
heap allocated, protect the structure definition with
#ifdef PANGO_ENABLE_BACKEND, and add getters for the fields.
* pango/pango-attributes.[ch] ( pango_attr_iterator_get_font):
instead of providing a base font description and one to fill
in, provide a single font description to modify based on
the attributes.
* pango/pango-attributes.[ch]: Fix PangoAttrFontDesc to have
a PangoFontDescription by reference, not by value.
* pango/pango-utils.[ch]: make pango_parse_style() and friends
take pointers to individual enumerations instead of to a
PangoFontDescription structure.
* pango/*.c: Fix for the PangoFontDescription and PangoFontMetrics
changes.
* pango/pango-{break,engine,indic,ot,xft}.h pango/Makefile.am
pango/opentype/Makefile.am: Protect portions with
PANGO_ENABLE_ENGINE to shrink the public API.
* modules/*/Makefile.am: -DPANGO_ENABLE_ENGINE.
* pango/{pangox.h,pangox-private.h} modules/basic/basic-x.c: Move
pango_x_font_get_unknown_glyph() into public header since it is
used from modules.

Tue Dec 19 22:47:16 2000 Owen Taylor <otaylor@redhat.com>
* configure.in pango-config.in pangoxft.pc.in
modules/basic/Makefile.am: Since Xft may only be available
statically without shlib deps, check for FreeType libs explicitly
and include them when linking, otherwise things won't work. Also,
define FREETYPE_CFLAGS from freetype-config --cflags.
* modules/basic/basic-xft.c pango/pangoxft-font{,map}.c: Fool
Xft into not converting glyph indices by loading the
face unencoded then calling FT_Set_Charmap ourselves.
* pango/Makefile.am pango/pango-ot.h pango/opentype/* :Add start
of opentype handling - most of the actually meat of the code here
is the OpenType layout code from FreeType 1 ported to freetype2
and adapted slighlty for our purposes. Also, includes a
incomplete OpenType-table-dumping code useful for figuring
out what is going on.
* pango/pangoxft.h pango/pangoxft-font.h: Add calls for
getting FT_Face and PangoOTInfo from PangoXftFont.
