Ebrahim Byagowi 44fe1c8ff1 Remove xlocale use now that isn't available in most distros 
Our CI bots don't detect it in Alpine, ArchLinux, Ubuntu and Fedora
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.

Khaled Hosny 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.

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.

Chun-wei Fan 91ca17e1fd src/hb-gobject-enums.cc.tmpl: Replace © with (C) 
This was, we also avoid Visual Studio compiler warnings C4828 as that sign is
not favored when /utf-8 is enabled, which is the norm nowadays as Visual Studio
2015 or later is required to build harfbuzz nowadays.

Tim-Philipp Müller 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.

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.

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.

 2019-12-31 13:52:50 +03:30
Khaled Hosny 68c1798a67 [coretext] Use kCTFontOpenTypeFeatureTag 
Instead of trying to map OpenType features to AAT feature selectors
which only works for a small subset of OpenType features, use the
simpler kCTFontOpenTypeFeatureTag with OpenType feature tags directly.

With this change, features like cvXX can be enabled in coretext shaper,
while they were previously ignored due to missing mapping.

This seems to work even with AAT fonts that don’t have OpenType layout
tables, which suggests that CoreText is doing the mapping itself in this
case.

kCTFontOpenTypeFeatureTag seems to have been introduced in macOS 10.10
and iOS 8.0, though, so its use is conditional on version check for now.
Not sure how to check iOS version, so I left this out.

Ben Wagner b918cd8c76 Document hb_feature_t. 
This documents hb_feature_t. This is motivated mostly by the ambiguity
of the units for 'start' and 'end' (clusters) and whether they are
inclusive or exclusive. This also documents that for lookup type 3 the
value is the one based index into the alternates and that in a list of
features later feature values override previous feature values with the
same tag.
