The specification moved around lately with how it defines its reports
and report bodies. They became dictionaries, but are currently missing
some fields [1].
Most tests won't be passing yet, since the `Reporting-Endpoints` header
isn't used yet. In fact, the specification leaves it up to the browser
to figure out when to run this task [2]. I am not sure if there some
background scheduling we can do here.
Confirmed with content-security-policy/reporting-api/
report-to-directive-allowed-in-meta.https.sub.html that the callback is
invoked. The test doesn't pass, since
the `describe_scripted_caller` is empty for HTML elements. Thus the
`source_file` is empty, whereas it should be equivalent to the current
document URL.

The will-navigate message tells the devtools client to expect a

[RootCause]:Tochdown executes normally, but touchup fails during hittest
and does not send a touchup event to the script, causing the script to
save an incorrect number of active_touch_points. The application
receives an incorrect event.touches.length, causing a logic error and
preventing the carousel from sliding.
[Solution]:
When hit test on compositor fails, we also need to send the
EmbedderToConstellationMessage::ForwardInputEvent message to
constellation. In the script's handle_touch_event, if it exits early, we
also need to update active_touch_points.

This pull request introduces changes to the storage subsystem to:

These changes bring Servo closer to spec compliance, matching expected

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).

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`

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.

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

Instead of doing a restyle whenever layout is requested, only do one if
script believes that the `Document` has changed in a way that needs a
restyle. In addition, track the different reasons this might be the
case. This will be used later to provide better debugging output.
In layout, when a restyle isn't requested, provide:
- an early return if layout is up-to-date enough for the reflow goal.
- skipping restyle and reflow if it isn't necessary.

This change fixes an issue and makes a few more minor improvements to
the `ImageAnimationState`:
1. Image rooting and unrooted now happens in one step from
`Window::update_animations_post_reflow`.
2. The `node_to_animating_image_map` is now stored as a shared `RwLock`
so that it doesn't need to be taken and then replaced in the
`ImageAnimationState` during reflow. This should prevent a hypothetical
issue
where image animations are restarted during empty reflows.
3. General naming and idiomatic Rust usage improvements.
Testing: This doesn't really have any obvious behavioral changes,
because all
reflows currently trigger a restyle. It becomes a serious problem with
#37677

- Instead of eagerly computing `pageX` and `pageY`, collect the offset
from the content's initial containing block in the compositor and pass
that information through to `MouseEvent`. This prevents a layout flush
that was happening when eagerly trying to fetch `Document` scroll
offsets.
- Pass keyboard modifiers properly to `MouseEvent`.
- Now all this information is stored and passed as `Point2D` (typed) and
`Modifiers` which greatly reduces the amount of arguments that need to
be passed around.
Testing: It is difficult to test input events as they require WebDriver
which
isn't completely working yet. I have manually run Speedometer 2.1 and I
