Jonathan Kew 1faf0caae1 Special-case 'smcp' when checking for exposed AAT features. 
This may be implemented by selectors under either LETTER_CASE or LOWER_CASE feature types
in AAT, so we need to check for the presence of either one.

Fixes #2307.
 2020-04-03 19:57:43 +04:30
Jonathan Kew b87cf6e8d4 Fix sense of comparsion in hb_aat_map_builder_t::feature_info_t. 
This makes bsearch actually work for the features array.

Fixes #2305.

Jonathan Kew b027cb518d Set sequence number when adding feature to aat map builder, to support stable sort. 
Fixes #2288.

Ebrahim Byagowi 89fa70f511 [aat] minor over previous feat related changes 2020-04-03 01:08:01 +04:30
Jonathan Kew b1c0b9da2f [AAT] Don't map OT tags to AAT feature types that are not exposed. 
If an AAT feature type is not exposed in the 'feat' table, we assume it is not intended
to be user-controllable and so we should not map any OT feature tag requests to it.

Fixes #2285.

build, later we need to have a separate harfbuzz-icu module and
link against that, and/or generate harfbuzz.cc.

Chun-wei Fan 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.

Khaled Hosny 14b5c774c2 meson: Fix include directory when used as subproject

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.

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.

Issue 1558: [subset] TrueType/CFF2 variable font
 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.
