We add scroll-timeline rule into the stylesheet rule type, and add a new
perference to protect it: layout.css.scroll-linked-animations.enabled.
We will use this perference for animation-timeline property as well.

We need to compute the anonymous name on the fly while building the
CascadeData, otherwise we may see the same layer rule in two places due
to stylehseet sharing and make them incorrectly share a name.

I'll add some tests before enabling. Also, WebKit folks (who have
implemented cos() / tan() / sin()) said they will upstream their tests
to WPT, so I'll extend those with the inverse functions before landing
as well.

The specifics of how this is going to work are still getting spec'd /
discussed in https://github.com/w3c/csswg-drafts/issues/6576, but this
allows DevTools to work fine and the feature to be complete enough for
Nightly experimentation (with the other in-flight patches).
Otherwise devtools crashes when trying to inspect pages that use them.

When we had:
@layer A.B;
We were registering "A" and "B", not "A" and "A.B", which was the intention.
Fix is trivial.

This makes layer order use a fixed set of bits per nesting level, to "reserve"
bits for children before they are registered.
See the comment in LayerOrder for the implementation limits it imposes, and
potential alternatives if these limits are not enough (but I think they should
be).
Enable the tests, as they mostly pass now (commit incoming to fix the remaining
ones).

This works modulo the existing nested layer order bug. Will be covered
by WPT /css/css-cascade/layer-import.html once the feature is enabled (I
can probably enable it right away for those tests, but I'd rather fix
the obvious bugs first).

Same, I want to land this separately to see if it affects
micro-benchmarks. If so, we might want to pack the layer order
_somewhere_ (though in this case I'm not sure where, tbh).
With this, layer rules should have an effect on the page. There are
a few things missing before being able to enable them:
* Fix nested layer order in some cases (when parent layers are declared
out of order, see the previous commit mentioning this).
* Some kind of OM representation, perhaps.
* Tests of course, which are coming in bug 1728722 and bug 1727276.
But this should be enough to allow playing with them.

I want to land this separately because we might want to get smarter with
the size of the Rule struct (maybe restricting layer order to a u8 per
scope and packing it with the source order, since 255 layers seem
plenty), but I'd rather do the obvious thing for now.

This code is really hot, and we've had perf regressions in the past for
introducing function calls in the hot path.
After the previous patch, add_rule is recursive and thus it can't be
inlined, causing a function call for each CSS rule.
This reduces the overhead by making the function take a rule list
instead, causing a function call per rule _list_, which should be
unnoticeable in practice.
Depends on D124335
Differential Revision: https://phabricator.services.mozilla.com/D124336
For that, deal with children in add_rule recursively, to keep the
current layer name up-to-date in block layer rules.
This is not the final version of this code, as right now something like
this:
@layer A {
...
}
@layer B {
...
}
@layer A.A {
...
}
Would give A.A more priority over B, which is not correct. There are
tests for this incoming in wpt sync and such, but that can be tweaked
later.
Differential Revision: https://phabricator.services.mozilla.com/D124335
This shouldn't have any behavior change, but is necessary because for
cascade layers we are going to need to handle the child rules / sheets
ourselves, in order to handle nested layers properly.

See the discussion here: https://twitter.com/Rich_Harris/status/1433153204678799365
This should make attribute selectors roughly as fast as class selectors.
I think it's worth trying and see if perf bots complain on
micro-benchmarks and stylebench and such.
I made attributes more specific than local names, but less specific than
classes, which I think makes sense. When doing something like
foo[data-bar], filtering by data-bar seems likely to yield less elements
than filtering by foo.
While at it, remove the bloom filter pref since we shipped it in
bug 1704551 for 87 and we haven't heard complaints.
Differential Revision: https://phabricator.services.mozilla.com/D124383
Not hooked anywhere yet, so this doesn't change behavior, but adds the
basic data model etc.
Adding parsing support requires some changes to cssparser to allow the
same at rule to be block and statement-like at the same time, so better
done separately.

Also, more directly go from StyleImageRendering to wr::ImageRendering.
* image-rendering: smooth the non-deprecated version of
OptimizeQuality, which maps to SamplingFilter::LINEAR /
wr::ImageRendering::Auto (which uses gl::LINEAR).
* image-rendering: pixelated maps to wr::ImageRendering::Pixelated /
SamplingFilter::POINT which is the same crisp-edges does.
Note that this uncovers that we were mapping image-rendering:
crisp-edges to wr::ImageRendering::Pixelated.
I'm going to preserve behavior on this patch but we should consider
switching that to map to wr::ImageRendering::CrispEdges on a
follow-up (filed bug 1728831 for this).

This is an oversight. I made selecteditem be -moz-html-cellhighlight,
but that's for inactive cells.
Use the inactive cell color everywhere (though android doesn't
differentiate). This matches other browsers and what was reviewed on
this bug.
MANUAL PUSH: The semi-transparent text-selection-disabled color caused
one test failure CLOSED TREE.

Clean up and document the `send_display_list` interface
This moves more members to the CompositorDisplayListInfo struct, which now holds all miscellaneous, non-WebRender data when sending display lists. It also documents what each things sent with a display list does.

Implement `bootstrap-gstreamer` for all platforms
This change makes it so that the Platform classes can now handle installing GStreamer dependencies and properly setting up the environment including when cross-compiling. For Windows and Linux, prepackaged GStreamer is now installed into `target/dependencies/gstreamer` when not installed system-wide. In addition this change:
1. The Environment path append helper is moved to `util.py` and a new `prepend` version is added.
2. `set_run_env` and `build_dev` functions are combined and include more code from callers so environment setup is more often in the same place. Now code that used to call `set_run_env` calls `build_dev` and then `os.environ.update(...)`. We can further refine this with the `is_build` argument later.
4. Python typing information is added in many places.

Remove outdated note on README (fix#29786)
This patch just removes a note about building only servo vs libsimpleservo binaries, as that's no longer working.
