Behdad Esfahbod 65392b734e [ucdn] Replace UCDN with a new UCD implementation
UCDN was ~120kb of data.  New implementatoin is 69kb in default builds,
and 49kb if built with HB_OPTIMIZE_SIZE or __OPTIMIZE_SIZE__.  The
latter automatically enabled if built with -Os or -Oz.

There's room to shave off another 10kb or 20kb.  That will follow later.

This is like hb_script_t.

We had this exposed as unsigned int since 2.0.0 release in two APIs,
as well as hb_ot_layout_get_size_params() from earlier.
But since no one uses those (right?!), let's just fix this now.

However HarfBuzz currently doesn't expose an API for retrieving the actual
information associated with NameId from the `name` table and that should be
done separately.

New API:

+hb_ot_layout_script_select_language()
+HB_OT_MAX_TAGS_PER_SCRIPT
+HB_OT_MAX_TAGS_PER_LANGUAGE
+hb_ot_tags_from_script_and_language()
+hb_ot_tags_to_script_and_language()

-hb_ot_layout_script_find_language()
-hb_ot_tags_from_script()
-hb_ot_tag_from_language()

Behdad Esfahbod cf975ac653 Remove use of deprecated function 2018-10-11 14:07:44 -04:00
David Corbett 91067716f5 Refactor the selection of script and language tags
The old hb-ot-tag.cc functions, `hb_ot_tags_from_script` and
`hb_ot_tag_from_language`, are now wrappers around a new function:
`hb_ot_tags`. It converts a script and a language to arrays of script
tags and language tags. This will make it easier to add new script tags
to scripts, like 'dev3'. It also allows for language fallback chains;
nothing produces more than one language yet though.

Where the old functions return the default tags 'DFLT' and 'dflt',
`hb_ot_tags` returns an empty array. The caller is responsible for
using the default tag in that case.

The new function also adds a new private use subtag syntax for script
overrides: "x-hbscabcd" requests a script tag of 'abcd'.

The old hb-ot-layout.cc functions,`hb_ot_layout_table_choose_script` and
`hb_ot_layout_script_find_language` are now wrappers around the new
functions `hb_ot_layout_table_select_script` and
`hb_ot_layout_script_select_language`. They are essentially the same as
the old ones plus a tag count parameter.

Closes #495.
