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.
