Matthias Clasen e7ab42b246 [layout] Fix handling of baseline variations
For BASE table format 1.1, the handling of design
space vs user space coordinates was inconsistent.
We were applying design -> user transformation
twice for the deltas, leading to wrong baseline
values.

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.
2022-02-17 16:21:22 +08:00
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 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.

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.
