[meson] increase subset tests timeout 
https://github.com/harfbuzz/harfbuzz/runs/676665822#step:6:570

fails because meson runs the tests in parallel, correct fix will be making the tests smaller

[aat] Fix implementation of AAT kerning for Geeza Pro. (#2388) 
* [aat] Fix implementation of AAT kerning for Geeza Pro.

Despite what the comment in the code used to say, it appears that Geeza Pro
does rely on accumulating kerning values from successive subtables. With
this change, the results now match Core Text rendering (and avoid the clear
visual breakage reported in #2358).

Testcase: U+0644,U+064E,U+0645,U+064E,U+0651,U+0627

Fixes #2358.

* [aat] Update test expectations, add new testcase.

c6b3f73b09 [meson] Make harfbuzz-icu separate module optout-able 2020-04-19 02:06:01 +04:30
Christoph Reiter
8ae06c9489 meson: build a separate library for harfbuzz-icu 
This adds a seperate library like with autotools.

This also fixes the ico feature option which was just set to required:false
when disabled instead of really disabling it.
Disabling is still broken with msvc because it then tries to find the library
another way, but that's broken for all other deps as well so I left it as is.

For tests only test-unicode.c is using icu specific functions so split it out
into its own category which depends on harfbuzz-icu.

Fixes #2338

a3892be701 [meson] fix spurious warning when building test/api C sources 
Fixes compiler warning

  test-unicode.c:589:1: warning: ‘test_unicode_properties_lenient’ defined but not used

which didn't happen with autotools.

Reason it does with meson is that the setup for C was slightly wrong.
We would only add -DHAVE_CONFIG_H to cpp_args which is only valid when
compiling C++ code, but not plain C code, and many of these tests were
plain C.

Instead pass -DHAVE_CONFIG_H via add_project_arguments() and make sure
to set both c_args and cpp_args when building test executables.

Even the face cmap12 and 13 have 32-bit hb_codepoint_t, which is here
used to make timeout, face's maxp has 16-bit gid limitation at least for now,
using that makes sure we both fix and the timeout and don't need to change
much things here also in order to support 32-bit gids also someday.

ff984ed3cd Use multiplication to avoid undefined behaviour per clang 
Newer versions of MSVC with /we4146 don't like putting negative sign behind a
unsigned number as https://github.com/harfbuzz/harfbuzz/pull/2069
That however have made https://crbug.com/1050424 this complain:
  src/hb-ot-color-sbix-table.hh:304:28: runtime error: negation of -2147483648 cannot be represented in type 'int';
                                        cast to an unsigned type to negate this value to itself
which apparently can be fixed using this change.

Let's see if this won't make another ubsan complain!

2742c81624 Fix page_map corruption in hb_set_t during process(). 
If a process operation results in less pages then the current set has, it will likely corrupt the page_map since it overwrites page_map entries ahead of where it's processing. This fixes that problem by removing page_map entries that will be dropped. Then dropping orphaned pages and re-indexing retained pages.

[subset] Avoid incorrectly dropping cmap for NotoColorEmoji.ttf 
NotoColorEmoji.ttf uses two cmap subtables

 Format 14 | Platform ID 0 | Platform Encoding ID  5
 Format 12 | Platform ID 3 | Platform Encoding ID 10

This combination results in the cmap table being dropped during subsetting despite being valid/required.
