This is part of the switch from `winapi` to `windows-sys`. `windows-sys` is
maintained by Microsoft, so is more "official." More and more crates are
switching to it.
Instead of linebreaking inside each single-font text segment, linebreak
the entire inline formatting context at once. This has several benefits:
1. It allows us to use `icu_segmenter` (already in use from style),
which is written against a newer version of the Unicode spec --
preventing breaking emoji clusters.
2. Opens up the possibility of changing the way that linebreaking and
shaping work -- eventually allowing shaping across inline box
boundaries and line breaking *after* shaping.

Instead of depending on `rust-freetype`, depend directly on
`freetype-sys` which is a transitive dependency. This provides almost
everything we need (apart from one function call). This will help us
eliminate one crate in the dependency chain.
For a long time, `gfx_traits` has held a lot of things unrelated to graphics
and also unrelated to the `gfx` crate (which is mostly about fonts).
This is a cleanup which does a few things:
1. Move non `gfx` crate things out of `gfx_traits`. This is important in
order to prevent dependency cycles with a different integration between
layout, script, and fonts.
2. Rename the `msg` crate to `base`. It didn't really contain anything
to do with messages and instead mostly holds ids, which are used
across many different crates in Servo. This new crate will hold the
*rare* data types that are widely used.
Details:
- All BackgroundHangMonitor-related things from base to a new
`background_hang_monitor_api` crate.
- Moved `TraversalDirection` to `script_traits`
- Moved `Epoch`-related things from `gfx_traits` to `base`.
- Moved `PrintTree` to base. This should be widely useful in Servo.
- Moved `WebrenderApi` from `base` to `webrender_traits` and renamed it
to `WebRenderFontApi`.
Color emoji support with "Noto Color Emoji" requires two things:
1. Support for bitmap fonts in the FreeType backend. This requires
specially handling bitmap fonts which have different characteristics
in the FreeType API (such as requiring metrics scaling). This support
is generally ported from Gecko's implementation.
2. When a character is an emoji it "Noto Color Emoji" needs to be in the
fallback list. Ensure that this is high on the list -- this will be
improved in a later PR.
* Use special WGPU poller thread for poll_all_devices
* Switch to latest wgpu
This is required to fix some deadlocks.
* non-blocking poll unconditionally
* small fixes
* Update wgpu to 0.20
* good expectations
* Throw TypeError in configure on unsupported format instead of panic
* Expect
* `into_command_buffer_id`,`into_command_encoder_id`
This allows sharing font templates, fonts, and platform fonts across
layout threads. It's the first step toward storing web fonts in the
layout versus the shared `FontCacheThread`. Now fonts and font groups
have some locking (especially on FreeType), which will probably affect
performance. On the other hand, we measured memory usage and this saves
roughly 40 megabytes of memory when loading servo.org based on data from
the memory profiler.

Bumps Stylo to servo/stylo#37
`white-space` is split into `white-space-collapse` and `text-wrap-mode`:
| white-space | white-space-collapse | text-wrap-mode |
| ----------- | -------------------- | -------------- |
| normal | collapse | wrap |
| nowrap | collapse | nowrap |
| pre-wrap | preserve | wrap |
| pre | preserve | nowrap |
| pre-line | preserve-breaks | wrap |
| - | preserve-breaks | nowrap |
Note this introduces a combination that wasn't previously possible,
but I think the existing logic can handle it well enough.
The old `allow_wrap()` is replaced by checking whether `text-wrap-mode`
is set to `wrap`.
The old `preserve_newlines()` is replaced by checking whether
`white-space-collapse` is *not* set to `collapse`.
The old `preserve_spaces()` is replaced by checking whether
`white-space-collapse` is set to `preserve`.
* Upgrade to stylo 6faedad
* Implement start, end, space-evenly content alignment + fix others
Update test expectations for content alignment fixes
Revert test expectations that are still generating the old results in CI
Update layout2013 test expectation for content alignment
Update content alignment fallback to use safe alignment
Implement fallback alignment
Update content alignment with recent spec changes
This change adds very basic support for `list-style-position`.
Currently, the marker does not do any kind of baseline alignment with
the rest
of the list item contents and it also doesn't force the list item to be
at least as tall as the marker.
This adds a few new failures:
- Four failures because markers do not ensure that list-items have at
least the same block size as they do:
- FAIL [expected PASS] /css/CSS2/lists/list-style-applies-to-012.xht
- FAIL [expected PASS] /css/CSS2/lists/list-style-applies-to-014.xht
- FAIL [expected PASS]
/css/CSS2/lists/list-style-type-applies-to-012.xht
- FAIL [expected PASS]
/css/CSS2/lists/list-style-type-applies-to-014.xht
- One failure because we don't yet support the `::marker`
pseudo-selector:
- FAIL [expected PASS]
/css/css-position/position-absolute-dynamic-list-marker.html
- One failure because we don't support the list item exception for the
line height quirk:
- FAIL [expected PASS] /quirks/line-height-in-list-item.tentative.html

Instead of using a strange number of spaces (5) for the example
override, use a single space. This makes it much easier to undo changes
to this file when switching between overriding a dependency and not
overriding a dependency.
Also switch from depending on `https://github.com/servo/style.git` to
the more common `https://github.com/servo/style`.
This brings the version of WebRender used in Servo up-to-date with Gecko
upstream. The big change here is that HiDPI is no longer handled via
WebRender. Instead this happens via a scale applied to the root layer in
the compositor. In addition to this change, various changes are made to
Servo to adapt to the new WebRender API.

This adds basic support for `text-transform` in a way that is more
complete than legacy layout. There are still many missing elements of
proper `text-transform` support such as:
1. Support for `full-width` and `full-size-kana`
2. Support for grapheme based uppercasing, lowercasing, and
capitalization. These are all done per-code point right now.
3. Support for the language-specific `SpecialCasing.txt` cases for case
mapping such as the ones for Irish and Turkish.

This fixes a warning from Cargo about relying on deprecated behavior:
```
warning: /home/loops/src/servo/servo/components/script/Cargo.toml: dependency (num_cpus) specified without providing a local path, Git repository, version, or workspace dependency to use. This will be considered an error in future versions
warning: /home/loops/src/servo/servo/components/config/Cargo.toml: dependency (num_cpus) specified without providing a local path, Git repository, version, or workspace dependency to use. This will be considered an error in future versions
```
This should fix issues that we have with Float16 support on newer LLVM.
This also updates style, in order to remove the duplicate version of
bindgen. We will soon be able to manage updates to style more
consistently.
