I kept it building the most straight-forward way possible (pub use) because it

This reduces a lot the boilerplate that's needed in order to add simple binding
functions.
This starts using &Foo and Option<&Foo> instead, and as a result we need to
remove the servo_function_signatures test, which is a bit unfortunate.
I think it's worth though, this causes problems on some platforms (see bug
1534844), and messing up the functions signature is not something that I've ever
seen (other than bug 1308234, which already had all the FooBorrowed mess which
I'm removing).
Also, cbindgen understands references and Option<&Foo>, so it will be the way to
go in the future.
After this patch we can also remove HasSimpleFFI, but I've kept it for now since
I still use it in a few places, and this patch is quite big on its own.

On the compositor side (i.e. received side of transactions). Basically, we
convert the list of layers::Animation into a list of `PropertyAnimationGroup`,
which is an intermediate value. And then use this list to do interpolation for

It's not very easy to understand on its current state, and it causes subtle bugs
like bug 1533654.
It could be simpler if we centralized where the interactions between properties
are handled. This patch does this.
This patch also changes how MathML script sizes are tracked when scriptlevel
changes and they have relative fonts in between.
With this patch, any explicitly specified font-size is treated the same (being a
scriptlevel boundary), regardless of whether it's either an absolute size, a
relative size, or a wide keyword.
Relative lengths always resolve relative to the constrained size, which allows
us to avoid the double font-size computation, and not give up on sanity with
keyword font-sizes.
I think given no other browser supports scriptlevel it seems like the right
trade-off.

We test the transform-style of a frame in places like
KeyframeEffect::CanAnimateTransformOnCompositor but this will likely not work as
expected for display:table content since the transform-style will not be
inherited to the primary frame (and later in this patch series we will ensure
that we are dealing with the primary frame in
KeyframeEffect::CanAnimateTransformOnCompositor).
The individual transform properties are new but they should also be inherited so
that all the appropriate tests for "is this frame transformed?" produce the
correct result when these properties are applied.

Nearly all of the build errors were for using the "Document" type without a
proper namespace, and I've addressed this by sprinkling "using namespace"
declarations in the affected .cpp files (and removing a few now-unnecessary
dom:: prefixes on types in those files).
The only other errors were for WorkletGlobalScope.h which needed an #include to
provide the type "DOMHighResTimeStamp", and nsHTMLStyleSheet.h which needed a
forward-declaration for the type "mozilla::dom::Document".

Calling getComputedStyle on an element outside of the document always returns

I chose a <meta> element instead of a <div> because they're undisplayed and they
don't cause the <body> of the document to start (though I _think_ that only
happens from the parser).

The only fishy bit is the animation stuff. In particular, there are two places
where we just mint the revert behavior:
* When serializing web-animations keyframes (the custom properties stuff in
declaration_block.rs). That codepath is already not sound and I wanted to
get rid of it in bug 1501530, but what do I know.
* When getting an animation value from a property declaration. At that point
we no longer have the CSS rules that apply to the element to compute the
right revert value handy. It'd also use the wrong style anyway, I think,
given the way StyleBuilder::for_animation works.
We _could_ probably get them out of somewhere, but it seems like a whole lot
of code reinventing the wheel which is probably not useful, and that Blink
and WebKit just cannot implement either since they don't have a rule tree,
so it just doesn't seem worth the churn.
The custom properties code looks a bit different in order to minimize hash
lookups in the common case. FWIW, `revert` for custom properties doesn't seem
very useful either, but oh well.

We could keep the warning like:

basis >= 0, "nscoord overflow?");
Which will catch cases where the style system would refuse to parse a negative
<length-percentage>, but we got a negative percent basis, which would be weird.
But that's a bit misleading since right now at least we rely on the caller to do
the appropriate clamping. I also think that NS_WARNING_ASSERTION is not very
useful, since we're not very likely to catch stuff with it. But anyhow, your

As it turns out we need this to avoid losing precision both during painting and
during serialization.
This patch also changes to serialize `context-value` if it's the computed value.
I could keep the previous behavior, but it makes no sense to serialize the
initial value. We're the only ones to support this value anyway, and I couldn't
find a definition or spec for this.
Also update tests and expectations for:
* New unexpected passes.
* Always serializing the unit in getComputedStyle.
* Calc and interpolation support.
Chrome also always serializes the unit in getComputedStyle, so I'm pretty sure
this is compatible with them. Chrome is inconsistent and keeps numbers in
specified style, but that's inconsistent with itself and with other quirky
lengths, so I updated the tests instead.

The main behavior changes are:
1) We no longer create a new Window when doing document.open(). We use the
same Window but remove all the event listeners on it and on the existing DOM
tree before removing the document's existing kids.
2) We no longer create a new session history entry. The existing one always
gets replaced instead.
3) We now support document.open on documents that are not in a Window.
The reasons for the various test changes are as follows:
The change to browser_modifiedclick_inherit_principal.js is because we no
longer set the docshell to a wyciwyg URL when document.open() happens and the
test was depending on that to terminate.
browser_wyciwyg_urlbarCopying.js is being removed because it's trying to test
wyciwyg URIs, which no longer exist.
The changes in docshell/test/navigation are because document.open() no longer
affects session history. One of the tests was testing the interactions there
and is being removed; another is being repurposed to just test that
document.open() does not affect history.length.
The change to test_x-frame-options.html is because document.open() now removes
event listeners on the window, which it didn't use to do (and in the specific
case in this test reused the existing inner too, so the listener was still
around in practice). The new behavior matches other browsers.
The removal of test_bug172261.html is because document.open() no longer affects
session history, so you can't go back across it or forward to the "opened"
state, so the situation that test is trying to test no longer exists.
The changes to test_bug255820.html are because reloading a document after
document.open() will now just load the URL of the document that was the entry
document for the open() call, not reload the written content. So there's not
much point testing reload behavior, and in this test it was just reloading the
toplevel test file inside the frames.
The change to test_bug346659.html is because now we no longer create a new
Window on document.open().
The change to test_bug1232829.html is because document.open() (implicit in this
test) no longer adds history entries, so the back() was just leaving the test
page instead of going back across the document.open(). The test is a
crashtest in practice, so might still be testing something useful about how
document.open() interacts with animations.
The change to test_bug715739.html is because the URL of the document after
document.open() is now the URL of the entry document, not a wyciwyg URL, so
reload() has different behavior than it used to.
The change to test_bug329869.html is because now when we go back we're
reloading the original document we had, not doing a wyciwyg load, and the
security info now doesn't include the untrusted script.
The changes to the wpt expectations are removing a bunch of expected failures
now that we pass those tests and disabling some tests that are fundamentally
racy and hence fail randomly. The latter all have github issues filed for the
test problem.
The change to testing/web-platform/tests/common/object-association.js is fixing
tests that were not matching the spec (and were failing in other browsers).
The change to parser-uses-registry-of-owner-document.html is fixing tests that
were not matching the spec (and were failing in other browsers).
The change to document-write.tentative.html is because the test was buggy: it
was using the same iframe element for all its tests and racing loads from some
tests against API calls from other tests, etc. It's a wonder it ever managed
to pass, independent of these patches (and in fact it doesn't pass according to
wpt.fyi data, even in Firefox).
The changes in html/browsers/history/the-history-interface are because
document.open() no longer adds history entries. The test was failing in all
other browsers for the same reason.
The changes in html/browsers/history/the-location-interface are because
reloading a document.open()-created thing now loads the URL of the page that
was the entry document for the open() call. The test was failing in all other
browsers.
The change to reload_document_open_write.html is because we now reload the url
of the document that entered the script that called open() when we reload, not
the written content. Other browsers were failing this test too; Gecko with
the old document.open implementation was the only one that passed.
The change to http-refresh.py is to fix a test bug: it was not returning a
Content-Type header, so we were putting up helper app dialogs, etc.
The change to test_ext_contentscript.js is because we no create a new global
for document.open() calls. Kris Maglione OKed this part.
