so let's get rid of it use the fallback we are using anyway for a
long time.

[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.

09b9d63e56 [blob] Try to support resource fork fonts on macOS 
If the size of opened file is zero, try opening resource fork by
appending "/..namedfork/rsrc" to the file name. This is guarded with
__APPLE__ ifdef and uses _PATH_RSRCFORKSPEC macro from sys/paths.h.

Defining HB_NO_RESOURCE_FORK will disable this fallback.

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.

4b4d5c295d src/meson.build: Some cleanups for Visual Studio builds 
We don't actually need the .def files (vs_module_defs) entry when we are
building DLLs with Visual Studio as long as we have HB_DLL_EXPORT defined.

Plus, to maintain compatibility with the CMake builds, for Visual Studio builds
we do not prefix the libraries with 'lib', nor have a '-0' suffix for the DLL
file name.

d230a02048 meson: generate .def file for MSVC symbol export on the fly 
Fix symbol export with MSVC when features are disabled,
such as GLib. We need to generate the list of exported
symbols on the fly to make sure we only export symbols
that are actually available.

Needs some minor modifications to the gen-def.py script:
 - accept header list also via command line args; we can't
   pass things to a configure_file() command via the environment
   in Meson.
 - strip any leading 'src/' from library filename. This might
   be there because in Meson the script might be called from
   the top-level directory and not the current source directory.

Remove .def files again which had been checked in for earlier
versions of the Meson port.

collect_unicodes() with clamp, calling add_range() 
Use add_range instead an inner loop, clamp its input number by
number of glyphs a face has.

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.
