The comment there was wrong. We just bail out from there only if
mIsRunningCompositor is false, so it doesn't matter whatever the layer
generation check results. (i.e., we don't bail out in the case where
mIsRunningCompositor is true).
Also, we iterate over mProperties in the LayerAnimationInfo::sRecords loop
through HasEffectiveAnimationOfProperty, so it doesn't matter that we iterate
mProperties before the loop either. We will avoid the iteration in the sRecords
loop in a subsequent patch in this series.

For some content both transitions and animations are triggered simultaneously.
As a result of bug 1301305, if the set of animations includes animations that
affect geometry, then we ensure that any transform animations are run on the
main thread, rather than on the compositor.
However, we have observed some content where this synchronizing is not necessary
and produces unnecessary jank. In the particular cases we have observed,
the transitions and animations do not need to be synchronized so this patch
refines the approach from bug 1301305 to only synchronize within the set of CSS
transitions or the set of non-transition animations.

step(_, jump-*) timing functions.
2. We still keep JumpEnd and End tags, even though there is no difference
between them. Therefore, we could disable the preference if needed.
3. Update the calculation of StepTiming to match the algorithm in the spec.
4. For servo, we implement the correct step function algorithm except
for the handling of before_flag. This could be fixed later.

First, we generate StyleComputedTimingFunction by cbindgen from Rust, and use
it in nsTimingFunction, so we could copy it directly without handling
the different memory layout. However, we have to rewrite the
nsTimingFunction and mozilla::ComputedTimingFunction for this.
Second, the rust-bindgen seems cannot generate the correct generic members
from complex C++ templates, especially for the nested template struct,
(https://github.com/rust-lang-nursery/rust-bindgen/issues/1429)
So we have to hide StyleTimingFunction to avoid the compilation errors.

This matches the spec, https://drafts.csswg.org/css-values/#angles, which says:
> All <angle> units are compatible, and deg is their canonical unit.
And https://drafts.csswg.org/css-values/#compat, which says:
>When serializing computed values [...], compatible units [...] are converted into a single canonical unit.
And also other implementations (Blink always serializes angles as degrees in
computed style for example).
Also allows us to get rid of quite a bit of code, and makes computed angle value
representation just a number, which is nice.

When a compositor animation finishes that doesn't apply a fill, rather than
jumping back to the underlying value immediately we should apply a fill mode
until the main thread has a chance to remove the animation from the compositor.
This ensures that any main thread effects that are intended to synchronize with
the end of the animation have a chance to run before we show the underlying
style and helps to avoid flicker in such cases.
Currently we apply this synthesized fill mode to animations when they run
forwards (i.e. positive playback rate), but not backwards. This patch makes us
apply the same handling when running in reverse.

Everything that goes in a PLDHashtable (and its derivatives, like
nsTHashtable) needs to inherit from PLDHashEntryHdr. But through a lack
of enforcement, copy constructors for these derived classes didn't
explicitly invoke the copy constructor for PLDHashEntryHdr (and the
compiler didn't invoke the copy constructor for us). Instead,
PLDHashTable explicitly copied around the bits that the copy constructor
would have.
The current setup has two problems:
1) Derived classes should be using move construction, not copy
construction, since anything that's shuffling hash table keys/entries
around will be using move construction.
2) Derived classes should take responsibility for transferring bits of
superclass state around, and not rely on something else to handle that.
The second point is not a huge problem for PLDHashTable (PLDHashTable
only has to copy PLDHashEntryHdr's bits in a single place), but future
hash table implementations that might move entries around more
aggressively would have to insert compensation code all over the
place. Additionally, if moving entries is implemented via memcpy (which
is quite common), PLDHashTable copying around bits *again* is
inefficient.
Let's fix all these problems in one go, by:
1) Explicitly declaring the set of constructors that PLDHashEntryHdr
implements (and does not implement). In particular, the copy
constructor is deleted, so any derived classes that attempt to make
themselves copyable will be detected at compile time: the compiler
will complain that the superclass type is not copyable.
This change on its own will result in many compiler errors, so...
2) Change any derived classes to implement move constructors instead of
copy constructors. Note that some of these move constructors are,
strictly speaking, unnecessary, since the relevant classes are moved
via memcpy in nsTHashtable and its derivatives.
Add tests for ComputeSquaredDistance on |offset-path:path()|.

flushComputedStyle is as follows:
var cs = getComputedStyle(elem);
cs.marginLeft;
That _probably_ flushes style in most engines, but it's possible some engine in
the future will optimize things in a way that it can flush marginLeft without
flushing, say, backgroundColor. Before moving these tests to wpt, it would be
better to explicitly flush the property (or at least one of the properties) we
are transitioning.
This patch also updates the "Setting zero combined duration" test from
test_animation-cancel.html since, in making this change, I realized the test was
wrong.
Specifically, it was testing that when we set a combined duration of zero that
a transition is canceled. However, nothing in the spec requires this. The spec
only requires a non-zero combined duration to _start_ a transition and only
cancels an existing transition if the combined duration becomes _zero_ if the
"the end value of the running transition is not equal to the value of the
property in the after-change style".
This test passed, however, because it changed the transition property to
margin-top, hence it was actually testing the same condition as the previous
test.

This patch splits the first test into four separate tests since it really seems
to be testing four different things.
Likewise, the later patch for replacing the effect is split into two parts:
- One to test the playState behavior
- One to test the value reported by transitionProperty
The test, "After setting a transition's effect to null, transitionend is still
dispatched", is dropped since it is covered by the last test in
test_event-dispatch.html.

This mostly just tidies up these tests to give them sensible titles.
The only test with major substantive changes is the first test. This test tests
three things:
1) That getAnimations() returns one transition per transitioning property
2) That getAnimations() returns transitions in the order they were generated
3) That CSS transitions have their start time set based on when they were
generated.
(2) is covered later in this file by the test: 'getAnimations sorts
transitions by when they were generated'
(3) is really a test for startTime, if anything, not getAnimations().
I'm not sure how necessary it is, but I've added it to
test_animation-starttime.html for now.
As a result, this patch updates this first test to only cover (1).

Apart from obvious tidy-ups the substantive changes to tests in this file are as
follows:
* Skipping forward through animation
-> This is really testing two things:
(a) That you can seek a transition using the start time.
(b) That seeking a transition using the start time triggers
dispatching events.
This patch splits the above into two separate tests.
* Skipping backwards through animation,
-> All these tests are really just exercising event dispatch which is
already covered by test_event-dispatch.html.
As a result this patch drops these tests.
* Setting startTime to null
-> Covered by 'Setting an unresolved start time sets the hold time'
in wpt/web-animations/timing-model/animations/setting-the-start-time-of-an-animation.html
* Animation.startTime after pausing
-> Covered by 'Pausing clears the start time'

This patch basically completely rewrites this file to make it simpler and remove
unnecessary tests.
In particular:
* It sets the duration and delay to 100s to match what we use in most tests
* All the helper methods at the start are inlined into the relevant tests
because doing so makes the tests much easier to read and debug.
* The first two tests are combined and extended
- Testing the initial current time is zero is not generally useful but it is
when we're testing setting it
- What the second test really wants to test is that the style updates (i.e.
you really can seek a transition, not just that the currentTime value
updates)
- The trick where we set the start time just to get out of the pending state
seems unnecessary, we may as well just wait on ready. In fact, we don't
_need_ to do that, but this test is about checking you can seek a transition
in motion.
* In the fourth test, 'Skipping backwards through transition', we don't check
the event is dispatched since that is covered in test_event-dispatch.html
in the 'Active -> Before' test.
* The final test, 'Animation.currentTime after pausing', is covered by
web-animations/timing-model/animations/pausing-an-animation.html
