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.

initialize iter before first usage to avoid immediate crashing
* pango/opentype/makefile.msc
pango/modules/makefile.msc : finally build with mscv, too.
[completely untested cause I'm not able to type, write or read
any of these languages]
* modules/modules.def : follow module function renaming/changes

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.

+=, and regularise them a bit (fixed a few bugs in the process).

gtk-doc.make.

* tests/Makefile.am: remove temporary files on clean.
Mon Feb 17 13:06:39 2003 Owen Taylor <otaylor@redhat.com>

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.

Rename from pango_fc_font_set_free to reflect
what it actually does.
* pango/pangofc-fontmap.cI pango/pangoft-fontmap.c

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,

reindentation.
