vello_cpu does not have any tests timeouts, because we do not need
download stuff from GPU as all work happens on CPU. So performance wise
it's better then classic vello at least for our usecase. There are some
vello bugs, but I think we will be able to sort them out within
upstream, eventually. Interestingly enough there are no new PASS like
they were with classic vello.
Difference with raqote can be observed here:

This change aims to supplement the missing incremental box tree

adjustments can alter visible text content and typography. Therefore,
the parent nodes of such text are marked as needing to re-collect their

Add vello backend by implementing Backend traits in canvas crate (so
this lives in canvas_paint_thread - embedded process). Current
implementation uses normal wgpu, so we block on GPU work. Vello backend
is gated behind `vello` feature and `dom_canvas_vello_enabled` pref.
Feature-wise this backend is on on par with raqote (sometimes better
sometimes worse), but performance wise it's worse.
## Known vello problems:
- image roundtrip does not work (fixed in
https://github.com/linebender/vello/pull/974)
- https://github.com/linebender/vello/issues/1066 (fixed)

- `/html/canvas/element/path-objects/2d.path.rect.selfintersect.html`
- There is currently no way to do put image properly in vello as we
would need to ignore all clips and other stuff (we try to work around
this on best effort basis)
https://github.com/linebender/vello/issues/1088
- `/html/canvas/element/pixel-manipulation/2d.imageData.put.*`
- precision problems
- `/html/canvas/element/path-objects/2d.path.stroke.scale2.html`
- `/html/canvas/element/path-objects/2d.path.arc.scale.1.html`
## Known servo problems
- bad performance due to blocking on GPU work
- some get/put intensive tests `TIMEOUT`
- proper shadow support (non-blocker as we already are living without it
now)
- support for rect shadow is there but unimplemented currently as that's
the state in raqote
Testing: `mach try vello` will run normal WPT (with raqote) +
vello_canvas subsuite that runs only on `/html/canvas/element`. All
subsuite expectations are stored separately.

This change optimizes `RestyleDamage` propagation and cleanup to reduce
unnecessary box reconstruction and relayouts, while preventing damage
from the current reflow affecting subsequent ones. Improvements include:
- For box damage caused by `NodeDamage`, `RestyleDamage::RELAYOUT` is no
longer marked immediately—avoiding erroneous propagation of
`LayoutDamage::RECOLLECT_BOX_TREE_CHILDREN` to descendants during
`RestyleDamage` propagation.
- Clearing damage for nodes whose boxes will be preserved, preventing it
from carrying over to the next reflow and increasing its workload.
Testing: This should not change observable behavior and is thus covered
by existing WPT tests. Although Servo lacks performance test cases,
manual testing shows that this modification reduces reflow time by
nearly 250ms, representing a decrease of approximately 25%.

This changes extend the incremental box tree construction for inline
boxes. Since an `InlineItem` can be split into multiple `InlineItem`s by
a block element, the reason such an inline item is marked as damaged may
simply be the removal of the block element or the need to reconstruct
its box tree. Therefore, under the current LayoutDamage design,
theoretically, even damaged inline items might still have some of their
splits reusable. However, based on the principle of simplicity and
effectiveness, this PR only considers reusing undamaged inline boxes.
Testing: This should not change observable behavior and is thus covered
by existing WPT tests.

HTMLImageElement was missing the dimension source attribute, as step 9

to use the [SpiderMonkey Debugger
API](https://firefox-source-docs.mozilla.org/js/Debugger/), we need to
call it from an internal debugger script that we will supply. this
script must run in the same runtime as the debuggee(s), but in a
separate
[compartment](https://udn.realityripple.com/docs/Mozilla/Projects/SpiderMonkey/Compartments)
([more
details](https://hacks.mozilla.org/2020/03/future-proofing-firefoxs-javascript-debugger-implementation/)).
when creating two globals in the same runtime, Servo will generally try
to reuse an existing compartment for the second global, and there are
other places in script where we rely on this reuse. but for the debugger
script, we can’t do this.
this patch adds a `use_system_compartment` flag to global object
descriptors, which isolates the global in its own compartment in both
possible directions:
- it forces the global to create a new compartment, preventing the reuse
of any debuggee’s compartment
- it fails the check in select_compartment(), preventing future
debuggees from reusing the global’s compartment
Testing: manually tested working in devtools debugger patch (#37667),
where it will undergo automated tests

Depends on #37427.
In addition to the changes introduced by
https://github.com/servo/servo/pull/37065, there are several performance
improvements and nits as follows:
- Use the internal pseudo element for style matching, this will reduce
the performance regression by ~66%.
- Manual construction of the `Text` node inside a text container. This
is followed by the modification of the inner `Text` node instead of
using `SetTextContent` which is more expensive.
- Use `implemented_pseudo_element` instead of
`text_control_inner_editor` `NodeFlag` to handle the special cases that
these elements should follow, specifically the:
- focus delegation workaround;
- selections; and
- line height resolving.
- More documentation.

Spec:
https://drafts.csswg.org/cssom/#dom-documentorshadowroot-adoptedstylesheets
Implement `DocumentOrShadowDOM.adoptedStylesheet`. Due to
`ObservableArray` being a massive issue on its own, it will be as it was
a `FrozenArray` at first. This approach is similar to how Gecko
implement adopted stylesheet. See
https://phabricator.services.mozilla.com/D144547#change-IXyOzxxFn8sU.
All of the changes will be gated behind a preference
`dom_adoptedstylesheet_enabled`.
Adopted stylesheet is implemented by adding the setter and getter of it.
While the getter works like a normal attribute getter, the setter need
to consider the inner working of document and shadow root StylesheetSet,
specifically the ordering and the invalidations. Particularly for
setter, we will clear all of the adopted stylesheet within the
StylesheetSet and readd them. Possible optimization exist, but the focus
should be directed to implementing `ObservableArray`.
