The CSSWG resolved that `block-size: stretch` on a block-level box
stretches the margin box to fill the parent. However, if the parent
doesn't have padding nor border, and doesn't establish an independent
formatting context, then we assume that the margins will collapse.
Therefore, we treat the margins as zero when resolving the stretch size,
regardless of whether they will actually end up collapsing.

We were ignoring `table-layout: fixed` both for `inline-size: auto` and
`inline-size: max-content`. However, the CSSWG resolved that fixed table
layout should be triggered except when `inline-size` is `auto`.

Two floats with `width: 50%` each should fit on the same line,
and four floats with `width: 25%` each should fit on the same line.
That's even if the containing block width, expressed in layout units,
cannot be divided by 2 or 4.
This test checks cases that are tricky for browsers where 1 pixel
are either 60, 64 or 100 layout units.
It passes on other browsers but fails on Servo because of #34665.

This changes `FlexItem::content_cross_size` into `Size<Au>` to preserve
keyword sizes. The calculation of the hypothetical cross size still
ignores them though, that will be addressed in a follow-up.
Also, browsers don't follow the spec and treat a stretch size different
than a stretch alignment: the former stretches to the containing block,
while the latter stretches to the line. This aligns Servo with that
behavior (following the spec would require bigger refactorings), so
`stretches()` is renamed to `stretches_to_line()` for clarity.

This is one of the first big steps toward making the compositor work
per-WebView. It moves the collection of pipelines into the per-WebView
data structure in the compositor as well as the pending paint metrics.
This means that more messages need to carry information about the
WebView they apply to. Note that there are still a few places that we
need to map from `PipelineId` to `WebViewId`, so this also includes a
shared mapping which tracks this. The mapping can be removed once event
handling is fully per-WebView.

Instead of keeping a per-FontGroup cache of the previously used fallback
font, cache this value in the caller of `FontGroup::find_by_codepoint`.
The problem with caching this value in the `FontGroup` is that it can
make one layout different from the next.
Still, it is important to cache the value somewhere so that, for
instance, Chinese character don't have to continuously walk through the
entire fallback list when laying out. The heuristic here is to try to
last used font first if the `Script`s match. At the very least this
should make one layout consistent with the next.

An intrinsic flex base size depends on the contents, which may depend on

can also be definite.

#30151 added support for setlike and maplike declarations in WebIDL, but
the tests only validated if generator code worked with 'DOMString' as
the key type. The support for interface type as members was broken as
`DomRoot<T>` didn't satify the bounds `Eq` and `Hash` needed by the
`Key` and `Value` types in `Setlike` and `Maplike` traits respectively.
In addition, the splitting of bindings into a separate 'script_bindings'
crate had also broken support for this in CodegenRust.py, as the types
used within the definition of `DomTraits` were not referenced using
`Self::`.
This patch fixes the WebIDL code generator by doing a simple string
replacement on the return value of `getRetvalDeclarationForType` so that
the proper `Self::` is used. I'm not not sure if there is a better
approach to this as it seems most logic in CodegenRust.py uses the `D::`
prefix that is expected to be available only when compiling `script`
crate and not `script_bindings`.
This patch also adds the missing trait implementations for `DomRoot` and
ensures that the generated code works for both members of primitive and
interface types by splitting the existing `TestBinding{Map,Set}Like`
interfaces into `TestBinding{Map,Set}LikeWith{Primitive,Interface}`
tests.
Fixes#35542.

A recent change, #35538 added the ability to dump different output image
formats. Unfortunately, this necessitated adding a file extension to the
output image for WPT tests. This had two problems:
1. The original change never landed properly in WPT for unknown reasons.
2. It interfered with the way that temporary files were cleaned up
during WPT runs.
This change modifies the image dumping code to fall back to PNG format
when there is no valid file extension on the output image and reverts
the change made to the WPT runner.

This is a step toward the renderer-per-WebView goal. It moves various
details out of `IOCompositor`.
- Image output: This is moved to servoshell as now applications can
access the image contents of a `WebView` via
`RenderingContext::read_to_image`. Most options for this are moved to
`ServoShellPreferences` apart from `wait_for_stable_image` as this
requires a specific kind of coordination in the `ScriptThread` that is
also very expensive. Instead, paint is now simply delayed until a
stable image is reached and `WebView::paint()` returns a boolean.
Maybe this can be revisited in the future.
- Shutdown: Shutdown is now managed by libservo itself. Shutdown state
is shared between the compositor and `Servo` instance. In the future,
this sharing might be unecessary.
- `CompositeTarget` has been removed entirely. This no longer needs to
be passed when creating a Servo instance.

This patch implements the `FontFace` interface, but with some caveats
1. The interface is only exposed on `Window`. Support for Workers will
be handled in the future.
2. The concept of `css-connected` `FontFace` is not implemented, so
`@font-face` rules in stylesheets will not be represented in the DOM.
3. The constructor only supports using `url()` strings as source
and `ArrayBuffer` and `ArrayBufferView` are not supported yet.
A skeleton implementation of the `load` method of `FontFaceSet` is also
implemented in this patch. The intention is to support some web pages
that don't load without this method.
