Add detail to hb_ft_font_create inline comments 
Providing lengthier explanation for how the destroy function works on the hb_font_t but that destroying the FT_Face (and not destroying it too early) remains the client's responsibility.

Ebrahim Byagowi 3737776384
[aat] add the bug link, minor 2020-04-03 20:03:20 +04:30
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.

Jonathan Kew b87cf6e8d4 Fix sense of comparsion in hb_aat_map_builder_t::feature_info_t.

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.

when HB_NO_VAR build config is used.

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

Chun-wei Fan 838346c54a meson: Support GDI integration

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.

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.

Khaled Hosny 14b5c774c2 meson: Fix include directory when used as subproject 
HarfBuzz headers are under src/ not the root directory, without using

incbase is superfluous, it should be replaced by incsrc or dropped.

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.
