Update of GPOS and GSUB support to OpenType 1.3
(From FreeType, Werner Lemberg, 2001-08-08)
* pango/opentype/ftxopen.h: Add RIGHT_TO_LEFT LookupFlag
* pango/opentype/ftxgpos.c (GPOS_Instance): Add 'first'
member to mark the beginning of a chain of cursive connections.
* pango/opentype/ftxgpos.c (Do_String_Lookup): If the
RIGHT_TO_FLAG flag is set, shift cursive chain up so
last glyph is on the baseline.
Fri Jul 25 22:59:13 2003 Owen Taylor <otaylor@redhat.com>
* pango/opentype/ftx{gpos,gsub}.h pango/opentype/ftxgdef.c:
Add GPOS_LOOKUP_EXTENSION, GSUB_LOOKUP_EXTENSION, which
allow lookup information to be stored at 32-bit offets
via a double indirection. (From FreeType, Werner Lemberg,
2001-08-08)
Fri Jul 25 22:25:48 2003 Owen Taylor <otaylor@redhat.com>
* pango/opentype/ftxgsub.c (Lookup_ContextSubst2,
Lookup_ChainContextSubst2): Fix a couple of
places where TTO_Err_Not_Covered wasn't considered
a successful return from Get_Class -- it means
use class index 0. (From FreeType, Werner Lemberg,
2001-08-06)
Fri Jul 25 20:12:00 2003 Owen Taylor <otaylor@redhat.com>
Improvements to OpenType-dumping code, based on
changes in Qt by Lars Knoll.
* pango/opentype/ottest.c: Tweak the debugging output,
suppress some warnings.
* pango/opentype/disasm.c: Add support for
GSUB Context/Chain GPOS MarkBase lookups, improve
output in various ways.
Thu Jul 24 17:04:21 2003 Owen Taylor <otaylor@redhat.com>
* pango/opentype/pango-ot-ruleset.c (pango_ot_ruleset_shape):
Fix uses of g_assert() around statements with side effects.
(#115498, patch from David Cuthbert)
Wed Apr 16 03:46:42 2003 Owen Taylor <otaylor@redhat.com>
* pango/opentype/pango-ot-info.c (synthesize_class_def):
More careful handling of face->charmap; if is NULL,
try to set a unicode charmap, if that doesn't succeed,
return. (Hopefully fixes#106550)
Tue Apr 15 11:49:39 2003 Owen Taylor <otaylor@redhat.com>
* pango/opentype/ftxg{sub/pos}.c: When loading
in Load_Chain{Sub,Pos}ClassRule, the limit we
have only applies to the input ClassDef table.
Fixes problem with Arial Unicode. Much help from
Noah Levitt in tracing this down.
Tue Apr 15 06:03:39 2003 Owen Taylor <otaylor@redhat.com>
* pango/opentype/ftxgpos.c: Fix confusion between
boolean and FT_Error return. (#108358, Noah Levitt)
* pango/opentype/ftxopen.c (Get_Class1): index is
allowed to be NULL. (#108358, Noah Levitt)
Tue Apr 15 05:00:39 2003 Owen Taylor <otaylor@redhat.com>
* pango/opentype/pango-ot-info.c (synthesize_class_def):
Fix infinite loop in the case where the charmap contains
a character > 65535. (#106550, Morten Welinder.)
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>
* configure.in **/Makefile.am: Add an --enable-debug
configure argument defaulting to 'yes' for unstable
releases and 'minimum' for stable releases.
For minimum, -DG_DISABLE_CAST_CHECKS.
* pango/pangofc-fontmap.cI pango/pangoft2-fontmap.c
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.
Wed Feb 12 16:59:23 2003 Owen Taylor <otaylor@redhat.com>
* configure.in pango/opentype/fterrcompat.h README:
Up the FreeType version requirement to 2.0.9.
(2.2.1 had a compilation failure with older versions,
this catches it more cleanly, and removes some unneeded
checks. #105302, problem reported by Will Partain.)
Fri Jan 10 18:56:36 2003 Owen Taylor <otaylor@redhat.com>
* pango/opentype/ftxgdef.c: Export TT_New_GDEF_Table
to create an empty GDEF table.
* pango/opentype/pango-ot-info.c: If the font doesn't
have a class definition table, synthesize one using
the charmap and the unicode properties of characters
in the charmap. (Needed to make things work with various
old Arabic fonts, such as the KACST fonts)
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.
Sun Sep 29 14:55:36 2002 Owen Taylor <otaylor@redhat.com>

Wed Aug 7 12:32:39 2002 Owen Taylor <otaylor@redhat.com>

Fri Mar 15 01:35:56 2002 Owen Taylor <otaylor@redhat.com>
* pango/opentype/ftxgsub.c pango/opentype/ftxopen.c
pango/opentype/ftxopenf.h: In Load_ChainContextSubst2,
handle the case where an empty class definition
is represented by an offset of 0.
* pango/opentype/ftxgpos.c: Same for Load_ChainContextPos2.
* pango/opentype/{ftxopen.c,ftxgpos.c,ftxgsub.c,ftgdef.c}:

an opaque heap-allocated structure, add accessors and
convenience functions.

heap allocated, protect the structure definition with
#ifdef PANGO_ENABLE_BACKEND, and add getters for the fields.

instead of providing a base font description and one to fill
in, provide a single font description to modify based on
the attributes.
