[shape-plan] Rename hb_ot_shape_plan_get_features to get_feature_tags
Simplify the API by returning only feature tags. The users of this API
would be interested only in feature enabled by default and whether the
feature is globally or partially enabled wouldn’t be of much interest in
that case. For user features, the user of the API already have full
access to them.

[shape-plan] Add hb_ot_shape_plan_get_features
This should get the features on a shape plan after executing it.
Initially I wanted to return an array of tags, but then there can be
user features that are not enabled globally, so I thought returning
hb_feature_t with value and range would be better. There is a TODO since
I couldn’t figure out how to get the value and range from the feature
mask. But also it may be overkill and a simple boolean indicating wither
it is a global feature or not would be enough.
I wounder also what should happen to non-user features that are applied
selectively, like init or medi, does ot make sense to indicate whether
they are global or not?
This is inspired by the discussion in:
https://github.com/fontforge/fontforge/pull/5522#pullrequestreview-2574321449,
but it might be useful to other HarfBuzz users.

|
|
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.

Fix requiredFeature stage handling logic
Originally the way Jonathan had written this was correct in
"continue"ing:
https://github.com/jfkthame/harfbuzz/commit/35e28c7a733eaffcd9f062b18d7db9fbb3d990fc#diff-ead86a33a5cc9ad7f6e6381031a0baddR199
When I rewrote his patch, I messed it up:
https://github.com/behdad/harfbuzz/commit/da132937989acb4d8ca9bd41c79f98750e7dda30#diff-ead86a33a5cc9ad7f6e6381031a0baddR209
the intended behavior was NOT to set found=TRUE and NOT to continue.
This was resulting in feature_index[table_index] being left unset.
Oops!

[Indic] Futher adjust ZWJ handling in Indic-like shapers
After the Ngapi hackfest work, we were assuming that fonts
won't use presentation features to choose specific forms
(eg. conjuncts). As such, we were using auto-joiner behavior
for such features. It proved to be troublesome as many fonts
used presentation forms ('pres') for example to form conjuncts,
which need to be disabled when a ZWJ is inserted.
Two examples:
U+0D2F,U+200D,U+0D4D,U+0D2F with kartika.ttf
U+0995,U+09CD,U+200D,U+09B7 with vrinda.ttf
What we do now is to never do magic to ZWJ during GSUB's main input
match for Indic-style shapers. Note that backtrack/lookahead are still
matched liberally, as is GPOS. This seems to be an acceptable
compromise.
As to the bug that initially started this work, that one needs to
be fixed differently:

[Indic-like] Disable automatic joiner handling for basic shaping features
Not for Arabic, but for Indic-like scripts. ZWJ/ZWNJ have special
meanings in those scripts, so let font lookups take full control.
This undoes the regression caused by automatic-joiners handling
introduced two commits ago.
We only disable automatic joiner handling for the "basic shaping
features" of Indic, Myanmar, and SEAsian shapers. The "presentation
forms" and other features are still applied with automatic-joiner
handling.
This change also changes the test suite failure statistics, such that
a few scripts show more "failures". The most affected is Kannada.
However, upon inspection, we believe that in most, if not all, of the
new failures, we are producing results superior to Uniscribe. Hard to
count those!
Here's an example of what is fixed by the recent joiner-handling
changes:

[GSUB] Wire the font, not just the face, down to substitute()
We need the font for glyph lookup during GSUB pauses in Indic shaper.
Could perhaps be avoided, but at this point, we don't mean to support
separate substitute()/position() entry points (anymore), so there is
no point in not providing the font to GSUB.

Enable applying GSUB/GPOS features in multiple segments
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=644184
among others.
Shapers now can request segmented feature application by calling
add_gsub_pause() or add_gpos_pause(). They can also provide a
callback to be called at the pause. Currently the Arabic shaper
uses pauses to enforce certain feature application. The Indic
shaper can use the same facility to pause and do reordering in the
callback.
