[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.

Ebrahim Byagowi 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

Tim-Philipp Müller 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.

Ebrahim Byagowi 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!

Garret Rieger 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] Raise the bar in new vs old table size
https://crbug.com/oss-fuzz/16740

This is actually an interesting thing that {h,v}mtx allocates as
much as a font pretends to have glyphs but the solution is not
that obvious as regular fonts can have less than actually containing
metrics in their {h,v}mtx. This change raises the bar to consider this
hmtx 4 byte for every glyph case.

Initially we wanted to just find things allocating crazy amount of
memory but having the assert has led to interesting findings also
so let's don't remove the assert and see what we can find elsewhere.

Increase subset fuzzer timeout to 16s
To satisfy -valgrind and -tsan bots, very ugly

Probably we should just remove timeout when running tsan and vaglrind here, the flaky bots

[metrics] Fix _get_variation API to works with actual coord values 2019-07-22 18:35:55 +04:30
Khaled Hosny c9796d15e1 Fix sbix glyph extents
* The ‘height’ needs to be negated since the API returns “distance from
  top to bottom side”.
* Similarly, the ‘y_offset‘ needs to be added to the height to get the
  ‘y_bearing’, since sbix’s offset is “the point in the glyph relative
  to its lower-left corner which corresponds to the origin” while
  ‘y_bearing’ is the “top side of glyph from origin”.

With these changes the sbix glyph metrics return values similar to other
tables, as they were otherwise unusable.
