Matthias Clasen d4cb07728c Add a missing file
The style test is using notosansitalic.ttf now,
but I forgot to add it with the test. Fix that.

Matthias Clasen 16b232be0e [hb-style] Fix the sign of slant ratios
We want negative slant angles to yield
positive slant ratios. Fix that.

Test included.

Matthias Clasen e76061a737 [hb-style] Fix synthetic slant values
When reporting the slant ratio of a font
that has synthetic slant set, we were
reporting twice the expected value.
Fix that. Test included.

Merge pull request #3449 from fanc999/msvc-meson-use-cmake
Meson: Use CMake more to find dependencies on Windows
2022-02-17 13:30:40 +02:00
Chun-wei Fan e6aa4b7d0e BUILD.md: Mention that installing CMake is recommended for MSVC
We are using CMake to help us find dependencies in Meson builds on Visual
Studio, so let people know that it's recommended.

Chun-wei Fan d24ac4aac3 freetype2.wrap: Provide fallback for CMake dep as well
Add a freetype identifier in the 'provides' section so that the fallback will
kick in if FreeType is requested but was not found, and wrap mode is not
disabled.

Chun-wei Fan f0573d8462 meson: Clean up finding ICU-UC on Visual Studio
Nowadays Meson has much better CMake support which we can use to find
dependencies on Visual Studio builds (and Visual Studio 2017 and later provides
CMake as an optional install item), so we can use it to help us find ICU-UC
on Visual Studio builds, since CMake has built-in support for finding it by
the components we need for some time.

Chun-wei Fan 561e8ba887 meson: Cleanup finding FreeType on Visual Studio
Nowadays, CMake is much better supported with Meson and is a common tool on
Windows (it is even an optionally-installed item for Visual Studio 2017+), so
make use of that to find FreeType.  The package to search for, however, is
`freetype` instead of `freetype2`.

Matthias Clasen 95bb2ff719 [ot-layout] Add central baselines
Add HB_OT_LAYOUT_BASELINE_TAG_IDEO_EMBOX_CENTRAL
and HB_OT_LAYOUT_BASELINE_TAG_IDEO_FACE_CENTRAL

Matthias Clasen f81578fd86 [ot-layout] Synthesize missing baselines
Add a variation of hb_ot_layout_get_baseline that
synthesizes missing baselines, using heuristics in part
taken from the CSS Inline Layout Module, Level 3.

Includes some new tests for synthesized baselines.
The base2.ttf is a subset of Noto Sans Bengali that
includes just the Bengali Ka.

New API: hb_ot_layout_get_baseline_with_fallback

Merge pull request #3410 from harfbuzz/boring-expansion
[Boring Expansion] >64k loca & hmtx tables

This does two things:

The num-glyphs reported by the face now is the maximum reported by the maxp and that deduced from the length of the loca table; I think this is the right thing to do anyway; According to OpenType such loca tables are invalid.

The interpretation hmtx tables that have excessive bytes at the end, again, invalid according to OpenType, has changed. Previously we were interpreting those excessive bytes as extra lsb values. Now we interpret them as extra advance values, the last of which is repeated for all missing glyphs. Again, these are tables that are invalid according to OpenType, and the advances are for glyph indices beyond maxp table's num-glyphs.

The combined effect is that the font can have shapes and advances for gid's beyond the maxp limit of 64k. In fact, maxp table becomes optional.

Ebrahim Byagowi 6b75a30a73 [draw/test] Swap a freetype test case with a simpler one
As CI failure, apparently the my local freetype and CI one have different
