layout: Remove LayoutRPC and query layout via the Layout trait (#31937)
Instead of the tricky `LayoutRPC` interface, query layout using the
`Layout` trait. This means that now queries will requires calling layout
and then running the query. During layout an enum is used to indicate
what kind of layout is necessary.

This change also removes the mutex-locked `rw_data` from both layout
threads. It's no longer necessary since layout runs synchronously. The
one downside here is that for resolved style queries, we now have to
create two StyleContexts. One for layout and one for the query itself.
The creation of this context should not be very expensive though.

`LayoutRPC` used to be necessary because layout used to run
asynchronously from script, but that no longer happens. With this
change, it becomes possible to safely pass nodes to layout from script
-- a cleanup that can happen in a followup change.

dependencies: Upgrade to WebRender 0.64 (#31486)
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.

fonts: Add FontIdentifier and LocalFontIdentifier (#31658)
Instead of using a simple `Atom` to identify a local font, use a data
structure. This allows us to carry more information necessary to
identify a local font (such as a path on MacOS). We need this for the
new version of WebRender, as fonts on MacOS now require a path.

This has a lot of benefits:
 1. We can avoid loading fonts without paths on MacOS, which should
    avoid a lot of problems with flakiness and ensure we always load the
    same font for a given identifier.
 2. This clarifies the difference between web fonts and local fonts,
    though there is more work to do here.
 3. This avoid a *lot* of font shenanigans, such as trying to work
    backwards from the name of the font to the path of the font we
    actually matched. In general, we can remove a lot of code trying to
    accomplish these shenanigans.
 4. Getting the font bytes always returns an `Arc` now avoiding an extra
    full font copy in the case of Canvas.

layout: Enable rendering of conical-gradient and repeating-conical-gradient (#31597)
This also ignores a clippy warning for a new function (and a similar
existing one), until this code can be refactored to use temporary Rust
strutures to carry display list building state.

There are a few new test failures here:

 - FAIL [expected PASS] /css/css-images/image-set/image-set-conic-gradient-rendering.html
 - FAIL [expected PASS] /css/css-images/image-set/image-set-repeating-conic-gradient-rendering.html

 These fail because Servo does not yet support `image-set()`.

 - FAIL [expected PASS] /css/filter-effects/filter-function/filter-function-conic-gradient.html
 - FAIL [expected PASS] /css/filter-effects/filter-function/filter-function-repeating-conic-gradient.html

 These fail because Servo does not support the very early filter effects
 specification.

 - FAIL [expected PASS] /html/canvas/element/manual/fill-and-stroke-styles/conic-gradient-rotation.html
 - FAIL [expected PASS] /html/canvas/element/manual/fill-and-stroke-styles/conic-gradient.html

 These fail because this change only adds support for CSS conical
 gradients. Another set of changes will be necessary to support this for
 Canvas.

layout: Turn on synthetic small-caps for layout 2020 (#31435)
Synthetic small caps is supported by the font subsystem, but this is
disabled in Layout 2020. We can turn this on to bring support to parity
with the old layout system.

In addition to turning on synthetic small-caps this change also improves
the way that they work. Before, synthetic small caps meant that every
character was a small version of capitalized character. After this
change, capital letters are larger than small caps versions of small
letters -- matching other browsers and the common expectation of how
small caps works.

script: Do not run layout in a thread (#31346)
* script: Do not run layout in a thread

Instead of spawning a thread for layout that almost always runs
synchronously with script, simply run layout in the script thread.

This is a resurrection of #28708, taking just the bits that remove the
layout thread. It's a complex change and thus is just a first step
toward cleaning up the interface between script and layout. Messages are
still passed from script to layout via a `process()` method and script
proxies some messages to layout from other threads as well.

Big changes:

1. Layout is created in the script thread on Document load, thus every
   live document is guaranteed to have a layout. This isn't completely
   hidden in the interface, but we can safely `unwrap()` on a Document's
   layout.
2. Layout configuration is abstracted away into a LayoutConfig struct
   and the LayoutFactory is a struct passed around by the Constellation.
   This is to avoid having to monomorphize the entire script thread
   for each layout.
3. Instead of having the Constellation block on the layout thread to
   figure out the current epoch and whether there are pending web fonts
   loading, updates are sent synchronously to the Constellation when
   rendering to a screenshot. This practically only used by the WPT.

A couple tests start to fail, which is probably inevitable since removing
the layout thread has introduced timing changes in "exit after load" and
screenshot behavior.

layout: Add support for table rows, columns, rowgroups and colgroups (#31341)
This adds support for table rows, columns, rowgroups and colgroups.
There are few additions here:

1. The createion of fragments, which allows script queries and hit
   testing to work properly. These fragments are empty as all cells are
   still direct descendants of the table fragment.
2. Properly handling size information from tracks and track groups as
   well as frustrating rules about reordering rowgroups.
3. Painting a background seemlessly across track groups and groups. This
   is a thing that isn't done in legacy layout (nor WebKit)!

Add support for table fixups (#30868)
This adds support for fixing up tables so that internal table elements
that are not properly parented in the DOM have the correct box tree
structure according to the CSS Table specification [1]. Note that this
only comes into play when building the DOM via script, as HTML 5 has its
own table fixups that mean that the box tree construction fixups here
are not necessary.

There are no tests for this change. In general, it's hard to write tests
against the shape of the box tree, because it depends on the DOM. We
plan to test this via WPT tests once layout is complete.

f4d3af296c Move *_traits and other shared types to shared
This is the start of the organization of types that are in their own
crates in order to break dependency cycles between other crates. The
idea here is that putting these packages into their own directory is the
first step toward cleaning them up. They have grown organically and it
is difficult to explain to new folks where to put new shared types. Many
of these crates contain more than traits or don't contain traits at all.

Notably, `script_traits` isn't touched because it is vendored from
Gecko. Eventually this will move to `third_party`.

Anonymous boxes that wrap inlines should not inherit overflow (#30579)
In legacy layout, anonymous text wrappers were inheriting the `overflow`
and `text-overflow` properties. This results in the creation of extra
clipping for these anonymous wrappers which could clip away floats. We
will likely implement `text-overflow` differently in non-legacy layout.

This change marks all legacy layout pseudo elements as "legacy" and also
adds a new pseudo element for non-legacy layout that does not inherit
`overflow`.

Fixes #30562.

Only access hit test items for the current epoch in the compositor (#30491)
When display lists update quickly, a hit test result might be returned
for a previous display list / list of hit test items. When that happens,
ignore the hit test result.

This fixes a crash, but there might be situations where we can do
something better, such as wait for display list processing to finish
before performing the hit test. A future change might do this for events
like mouse clicks and touch events that should never be thrown away.
Ultimately, the best thing is likely moving hit testing back to layout
or script so a valid hit test can always be performed against the
current DOM.

Fixes #29796.

Refactor scrolls on the window object (#29680)
Refactor the scrolling and scrollable area calculation on the window
object, to make it better match the specification. This has some mild
changes to behavior, but in general things work the same as they did
before. This is mainly preparation for properly handling viewport
propagation of the `overflow` property but seems to fix a few issues as
well.

There is one new failure in Layout 2020 regarding `position: sticky`,
but this isn't a big deal because there is no support for `position:
sticky` in Layout 2020 yet.

Layout 2013: Don't use WebRender border image outset support (#30315)
The border image outset support in WebRender is going to be removed and
even in versions of WebRender where it still exists, it fails to render
properly.

A border image is a type of border composed of slices of images. The
"outset" of this kind of border is a property in CSS that makes the
border boundaries expand. Previously, the value was passed to WebRender
which would expand the border by this amount and render the images into
the expanded rectangle.

Since this is going to be removed, we handle this property outside of
WebRender. The change is simply to expand the border area by the outset
before calculating the rest of the border values.

This is necessary for the WebRender upgrade.

Backport several style changes from Gecko (5) (#30099)
* style: Simplify selector flag setting now that flag setting is atomic

These bits are write-only, actually, and we don't even need to read
them.

Differential Revision: https://phabricator.services.mozilla.com/D141888

* Further changes required by Servo

* style: Support media queries for dynamic-range and video-dynamic-range

This is a stub that only matches "standard" for all platforms.

Differential Revision: https://phabricator.services.mozilla.com/D141053

* style: Remove :-moz-lwtheme-{brighttext,darktext}

They are just convenience for :root[lwthemetextcolor="light"] (and dark,
respectively), but they generally shouldn't be used for dark mode
theming. In the past it was the only way to do it but now we have
prefers-color-scheme.

While at it, change lwthemetextcolor to be "lwtheme-brighttext" for
consistency with similar code we have for popups etc, and move it to
_setDarkModeAttributes.

While at it, remove layout.css.moz-lwtheme.content.enabled (which is
false always, we unshipped these from content successfully).

Differential Revision: https://phabricator.services.mozilla.com/D141593

* style: layout.css.moz-locale-dir.content.enabled

We successfully removed these from content in bug 1740230 (Firefox 96).

Differential Revision: https://phabricator.services.mozilla.com/D141727

* style: Really honor background-color: transparent in HCM even for form controls

I forgot we were doing this "revert-or-initial" shenanigans (which is needed
for stuff like link colors to be honored), so we need to early-return.

Use a more explicit test rather than a reftest for this.

Differential Revision: https://phabricator.services.mozilla.com/D142063

* style: Ignore unchanged property for scroll-linked effect detector

I think this is cleaner.

Differential Revision: https://phabricator.services.mozilla.com/D141737

* style: Allow to derive Parse/ToCss/SpecifiedValueInfo on bitflags

We keep getting this pattern of properties that have a set of joint and
disjoint flags, and copy-pasting or writing the same parsing and
serialization code in slightly different ways.

container-type is one such type, and I think we should have a single way
of dealing with this, thus implement deriving for various traits for
bitflags, with an attribute that says which flags are single vs mixed.

See docs and properties I ported. The remaining ones I left TODOs with,
they are a bit trickier but can be ported with some care.

Differential Revision: https://phabricator.services.mozilla.com/D142418

* Further changes required by Servo

* style: Implement parsing / serialization for container{,-type,-name} CSS properties

Two noteworthy details that may seem random otherwise:

 * Moving values around in nsStyleDisplay is needed so that the struct
   remains under the size limit that we have to avoid jumping allocator
   buckets.

 * All the test expectation churn is because tests depend on
   `container-type: size` parsing to run, and now they run. Tests for
   the relevant bits I implemented are passing, with the only exception
   of some `container-name-computed.html` failures which are
   https://github.com/w3c/csswg-drafts/issues/7181. Safari agrees with
   us there.

Other notes when looking at the spec and seeing how it matches the
implementation:

 * `container` syntax doesn't match spec, but matches tests and sanity:
   https://github.com/w3c/csswg-drafts/issues/7180

 * `container-type` syntax doesn't _quite_ match spec, but matches tests

* style: Deduplicate TokenList values faster

Remember whether we have already de-duplicated them once and avoid doing
that again.

This is an alternative approach that doesn't add overhead to attribute
setting in the general case.

* style: Inherit used color-scheme from embedder <browser> elements

This allows popups and sidebars to use the chrome preferred
color-scheme.

This moves the responsibility of setting the content-preferred color
scheme to the appropriate browsers to the front-end (via tabs.css).

We still return the PreferredColorSchemeForContent() when there's no
pres context (e.g., for display:none in-process iframes). We could
potentially move a bunch of the pres-context data to the document
instead, but that should be acceptable IMO as for general web content
there's no behavior change in any case.

* Further changes required by Servo

* style: Tweak cascade priority to split writing-mode and font properties

This makes the worst case for cascade performance slightly more
expensive (4 rather than three declaration walks), but my hope is that
it will make the average case faster, since the best case is now just
two walks instead of three, and writing mode properties are somewhat
rare.

This needs a test, but needs to wait until the writing-mode dependent
viewport units land (will wait to land with a test).

* style: Fix visited handling after bug 1763750

Before bug 1763750, we unconditionally called compute_writing_mode,
which got the writing mode from the cascade mode for visited styles.

However after that bug we only do that if we apply any
writing-mode-related property.

We could just call compute_writing_mode unconditionally, but instead it
seems better to skip all that work for visited cascade and reuse the
mechanism introduced in that bug to only apply the visited-dependent
longhands.

We assert that all visited-dependent longhands are "late" longhands, so
as to also avoid applying the font group and such.

* style: Simplify media query evaluation code a bit

This patch:

  * Removes generic <ident> support for media features. These were used
    for some privileged media features but are no longer used.

  * Simplifies media feature getters by shifting the responsibility of
    dealing with RangeOrOperator to the caller. This makes it easier to
    implement container-query / mediaqueries-4 syntax, and also cleans up
    the code a bunch.

There should be no change in behavior.

Differential Revision: https://phabricator.services.mozilla.com/D144051

* Further changes required by Servo

* style: Move transitions and animations to nsStyleUIReset

This mostly just moves code around, to minimize potential behavior
changes. There are some cleanups that we should try to do long term
(this "have an array with n different counts" is pretty weird).

But for now this should unblock people.

The destination struct (nsStyleUIReset) was chosen mainly because it's
small and non-inherited, and it doesn't seem like a worse place than
nsStyleDisplay.

* Further changes required by Servo

* style: Make media feature evaluation take a computed::Context

This has no behavior change right now, but will simplify sharing code
with container queries.

Container queries will have container information in the
computed::Context (this is necessary anyways for container-based units),
so this avoids having to have different code for media and container
queries.

* Further changes required by Servo

* style: Add scroll() to animation-timeline for style system

scroll() is defined in the spec proposal, and there is a temporary spec:
https://drafts.csswg.org/scroll-animations-1/rewrite#scroll-notation.

The spec is still under development, so we don't drop the orignal
scroll-timeline at rule. Instead, we add a new scroll() notation to
animation-timeline, and support both syntax for now.

Differential Revision: https://phabricator.services.mozilla.com/D143417

* style: Tweak contain bitflag definition order to avoid static constructors

This has no behavior change otherwise. The STRICT definition depended on
SIZE, which was defined later. That's fine in Rust, but in C++ it causes
the initialization to be dynamic because it doesn't have the definition
of SIZE yet (ugh).

This is the fix for the regression, though the following patch turns on
constexpr support in cbindgen, which would've caught this at build-time,
and guarantees that we don't have extra static constructors.

Differential Revision: https://phabricator.services.mozilla.com/D144316

* style: Move some of the media query code to a more generic queries module

No behavior change, just moving and renaming files.

The code in the "queries" module will be shared between @media and
@container.

@media has some other code that container queries doesn't need like
MediaList / MediaType / etc. That remains in the media_queries module.

Make the representation the same between Gecko and Servo code. This will

Make serialization be correct, serializing as identifier unless it's an

This changes our stringification behavior in the specified style, but
now it will match the computed style and be more correct over-all.

cross-fade() was kinda doing this in its own way with PercentOrNone, but

let me know if you want them gone.

* style: Simplify selector flags setup even more

In my investigation for bug 1766439, I am digging into why selector
matching regressed.

It doesn't help that the selector-matching code is instantiated a
gazillion times (so there's a ton of copies of the relevant functions).

This was needed in the past because we had different ways of setting the
selector flags on elements, but I unified that recently and now we only
need to either set them or not. That is the kind of thing that
MatchingContext is really good for, so pass that instead on
MatchingContext creation.

* style: Track @container condition id in style rules

Much like we track layer rules. Consolidate that "containing rule state
we pass down while building the cascade data" in a single struct that we
can easily restore.

For now, do nothing with it. I want to land this patch separately
because it touches the Rule struct and CascadeData rebuilds, which both
are performance sensitive.

Its layout shouldn't change because I also changed LayerId to be a u16
(this shouldn't matter in practice, since LayerOrder is already a u16).

* style: Clean up unused -moz-window-shadow values

After bug 1768278 and bug 1767815 there's no more uses of the cliprounded value
in the tree (also it causes artifacts on HiDPI screens so we probably don't
want new usages).

The "sheet" value is unused, and the other values other than "default" and
"none" are only derived from "default", so they don't need to be exposed in the
style system.

Differential Revision: https://phabricator.services.mozilla.com/D145821

* style: More container queries plumbing

Provide container information in computed::Context and use it to resolve
the container queries.

This still fails a lot of tests because we are not ensuring that layout

expected.

This reuses our existing undisplayed style generation, but in a

much more often.

This brings the test-case in the bug to par with other browsers or
better, and is much simpler than the initial approach I tried back in
the day.

Use explicit WebRender hit test items in legacy layout (#29981)
Including hit tests in non-hit test display list items is no longer
