Tim-Philipp Müller 7eaf3754dc meson: update for changes in master 
And remove header files from sources list, Meson figures
out header dependencies by itself (via the compiler).

Tim-Philipp Müller 618584e923 meson: rename incbase to incconfig 
Makes it clearer what it's for: config.h. See #4.

Khaled Hosny 14b5c774c2 meson: Fix include directory when used as subproject 
HarfBuzz headers are under src/ not the root directory, without using
incsrc no headers will be found by the dependent project. I think
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.

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.

[glyf] Don't accept gids higher than maxp's glyphs number 
This specially becomes concerning on sub-components where a gvar table
that is sanitized using maxp's glyphs number overflows when a high gid
accepted here goes to it, maybe an additional check can be put there
also, this however feels to be enough.

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!

Ebrahim Byagowi 40166eb0e5 [var] Fix the just introduced hb_font_set_var_coords_design storing bug 
The memcpy call was using the current coords count which is zero initially so no copy at all.

Sad that no test has caught it, should see why, will however with the upcoming style API tests.

Garret Rieger 5a10f3a055 Use vector instead of map during page compaction in hb-set. 2020-02-08 10:27:44 +03:30
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.
