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.
