`Node::dirty` already increments the version. `Node::rev_version`
traverses all ancestors, so it can end up being fairly expensive.
Testing: I'm not sure about WPT coverage but I think this change is
trivial enough to merge without tests.

I introduced snapshot in #36119 to pack raw bytes and metadata together,
now we take the next step and require for user to always specify what
kind of byte data they want when calling `as_bytes` or `to_vec`
(basically joining transform and data). There are also valid usages when
one might require just one property of bytes (textures can generally
handle both RGBA and BGRA). There are also valid usages of using just
raw bytes (when cropping). This PR tries to make such usages more
obvious.
This will make it easier to fix stuff around 2d canvas (we do not want
to assume any bytes properties in abstraction).
Testing: Code is covered by WPT tests.

This creates a new method in shared/compositing/lib to generate image
keys that are send over the webview. This does not immediately return
the keys but goes over the constellation to receive the keys from the
IOCompositor. To make this more efficient, we now cache the keys in
image_cache in a simple FIFO order. The old blocking method stays intact
for now but got renamed to make the blocking clear.
The blocking calls that are left are in:
- `components/canvas/canvas_data.rs`
- `components/script/dom/htmlmediaelement.rs`
Testing: WPT tests should cover this as this doesn't change any
functionality.

Previously, our Servo-specific spatial tree scroll offsets were opposite
to
that of WebRender and also the web platform. This is due to the fact,
likely, that `winit` wheel directionality is also flipped. This change
has both the Servo spatial tree and the API take offsets that are
consistent with the web.
Any possible changes to the meaning of wheel directionality will be
handled in a followup change.
This is a breaking change to the Servo API.
Testing: This change updates unit tests.

Signed-off-by: Oriol Brufau <obrufau@igalia.com>
This change:
- Adds a new type of LayoutDamage that signifies that a box needs its
children recollected, because one or more of them need to be rebuilt.
- During restyle damage propagation, propagate this new damage upward in
the tree. Then box tree construction should be able to preserve any
still-valid box tree nodes from box slots.
- During BlockLevelBox job finalization, if a box slot is valid and
there is not LayoutDamage to the element, use the old box slot,
ensuring that its fragment cache is invalidated.
Testing: This should not change observable behavior and thus is covered
by existing WPT tests.

This PR adds backtrace demangling to background hang monitor, thereby
removing a `TODO` in the component source.
The required `rustc-demangle` crate dependency is gated behind
`#[cfg(feature = "sampler")]` as it is my understanding that the
surrounding code is only called when `sampler` is enabled.
Testing: testing was done manually - I suppose a substring match for a
known demangled string could be used for adding a proper test case, and
checking `RUSTFLAGS` to discern whether `v0` demangling should be
expected? Open to suggestions. Manual testing was done by printf
debugging (not part of the PR):

modifies those parts to use non-parallel iterators when
`LayoutContext::use_rayon` is not active.

Currently, HTMLImageElement uses as an image source
(ImageBitmapSource, CanvasImageSource, TexImageSource)
in various canvas2D/WebGL operations, and there is a small
inconsistency in how we get the image data of the 'img' element:
usability checking and retrieving the image data from the image cache.
To simplify and avoid state inconsistency between the window's image
cache and the 'img' element, let's retrieve the image data (as a raster)
from the HTMLImageElement itself.
Testing: No expected changes in testing results, except the
'drawimage_svg_image_with_foreign_object_does_not_taint.html'
which is 'false' passed because drawing of the non supported vector
image
is silently skip instead of throwing the 'InvalidState' exception
anymore.

1. Remove the unnecessary new thread which use GetWindowRect command and
blocks for 500ms. Previously this is necessary because constellation
forward "resize" to embedder, and WebDriver wait for a constant
sufficient time to `GetWindowRect` in the new thread. This caused long
delay because there are many subtests and SetWindowRect is called
between each.
2. Remove `resize_timeout`
3. Return current dimension instead of 0 from embedder when it fails to
resize.
4. Do resizing as long as one of width/height is `Some`, according to

#37433 didn't handle intrinsic contributions. This patch computes the
correct SizeConstraint to be used as the ConstraintSpace's block size
when computing intrinsic inline sizes.
Testing: Adding new test

Add methods to retrieve the natural, default and fallback sizes per each
axis (inline or block), rather than computing both simultaneously.
Sometimes we only want one size, and I think it's clearer this way.
Testing: Unnecessary (no behavior change)

`FlexContainer::layout()` was forcing `depends_on_block_constraints` to
true for `flex-direction: column`. However, it doesn't make sense to do
that only for `column` but not for `column-reverse`. Also no test is
complaining, so I'm just removing that logic.
Testing: no behavior change is intended, so just existing test coverage

Cloned nodes were re-parsing already-parsed style attributes. As such,
they were also checking CSP, which shouldn't happen as the original node
already was checked for it.
Testing: The existing WPT test now mostly passes. It had two cases which
were passing in no browsers.
Fixes: Part of #4577

This PR moves canvas paint thread initialization to constellation. This
allows us to lazily initialize it on first create canvas request (like
we do for webgpu). If we didn't started canvas paint thread we also do
not need to wait for it's teardown.
Per https://chromestatus.com/metrics/webfeature/timeline/popularity/201
~30% of websites still use 2d canvas.

The creation of `LayoutContext` does more work than necessary if layout
just needs to do something like make a display list and not restyle and
relayout. This change makes it so that these kind of non-restyle layouts
do not need to create a display list. In addition, the creation of
`LayoutContext` is better encapsulate
Testing: This should not change observable behavior and is thus covered
by existing WPT tests.

- Move some of the image handling code to a separate function.
- Move reflow event debugging into layout itself and use the `Debug`
implementation to print the event.
- A few other small cleanups

This PR removes `unwind-sys` usage from background_hang_monitor on
Linux, replacing it with the [backtrace
crate](https://crates.io/crates/backtrace).

All "Find Element ..." in
[spec](https://w3c.github.io/webdriver/#find-element-from-element) has
exactly same step has "Find Elements ...", except they extract the first
element if there is any. We now reuse the handler instead of running
numerous repetitive steps, same as what we did for ["Find Element from
Shadow
Root"](https://w3c.github.io/webdriver/#find-element-from-shadow-root)
in #37578.
This reduces binary size by 98KB for Release profile in Windows and
improves maintainability.

This reduces the amount of work necessary when running layout, by making
restyle information optional in the `ReflowRequest`. When restyling
isn't
necessary, the option is `None`.
Testing: This shouldn't change any observable behavior and thus is
covered
by existing WPT tests.

When parsing a html fragment, the initial parser state depends on
whether or not scripting is enabled. So far we've used the scripting
flag of the parser, but that is wrong - the parser's scripting flag is
always false, because the fragment document has no browsing context.
Instead we should use the scripting flag of the context element.

Before we only offered helper to add single image (no update or delete)
that got special IPC message, now we simplify this by offering all ops
helpers for dealing with single image (that happens most of the time),
that simply uses `update_images` under the hood. We also optimize for
this use case by using `SmallVec<[ImageUpdate; 1]>` to avoid alloc.
Testing: Just refactor, but code is covered by WPT tests

This will allow Servo to add custom types of damage in the near future
which correspond to minor phases layout. The damage exposed by Stylo
only corresponds to the major layout phses. In the future, both phases
will likely be managed by Servo itself and implementors will need to
provide their own damage system entirely.
Testing: This shouldn't change behavior and thus is covered by existing
tests.

webgpu currently sends updates WebRender directly via WebRender API
(same as webgl that I also plan to reform). 2D canvas uses Compositor
API for that and with this PR so does webgpu. This will be helpful for
#35733, where compositor must know state of image updates.

This is used to capture information about what layout phases are
necessary for a given `ReflowGoal`. It's moved closer to where these
decisions are made and it should be easier to understand what the values
mean. They had gotten a bit out of sync with how queries and layout were
implemented.
Testing: This shouldn't change observable behavior and thus should be
covered
by existing WPT tests.

Like in #37713, instead of updating images directly with webrender api
we use the compositor api. We still keep webrender api available in
webgl, because that's where we do shutdown, due to GL.
