        * ftxgdef.[ch] otlbuffer.[ch]: Make Check_Property() take a
        OTL_GlyphItem, add a gproperties field to OTLGlyphItem,

        to output that preserves the cached properties.

Owen Taylor a7e096c5de Rework opentype interfaces and other changes to make GPOS work for Arabic.
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.

        * pango/opentype/pango-ot-ruleset.c (pango_ot_ruleset_shape):
        Sign convention for y offsets is opposite between
        PangoGlyphString and FT code. (#132591)
