Part of Bug 325714 – Pango should respect $LANGUAGE
* pango/pango-ot.h:
* pango/pango-ot-private.h:
* pango/pango-ot-tag.c (pango_ot_tag_from_script),
(pango_ot_tag_from_language):
* pango/pango-ot-info.c (pango_ot_info_find_script),
(pango_ot_info_find_language), (pango_ot_info_find_feature),
(pango_ot_info_list_languages), (pango_ot_info_list_features):
* pango/pango-ot-ruleset.c (pango_ot_ruleset_new),
(pango_ot_ruleset_new_for), (pango_ot_ruleset_add_feature),
(pango_ot_ruleset_maybe_add_feature),
(pango_ot_ruleset_maybe_add_features):
Add new engine API:
PANGO_OT_NO_FEATURE
PANGO_OT_NO_SCRIPT
PANGO_OT_TAG_DEFAULT_SCRIPT
PANGO_OT_TAG_DEFAULT_LANGUAGE
pango_ot_ruleset_new_for()
pango_ot_ruleset_maybe_add_feature()
pango_ot_ruleset_maybe_add_features()
Using pango_ot_ruleset_new_for() and
pango_ot_ruleset_maybe_add_features() drastically simplifies ruleset
building in modules, and does correct script and language selection
too. Modules need to be updated to use it though.
* docs/pango-docs.sgml:
* docs/pango-sections.txt:
* docs/tmpl/opentype.sgml:
Update.
