Animation::FlushStyle() gets called only for CSS animations/transitions'
playState changes in JS or ready Promise for CSS animations. In either case
throttled animation state, which is, to be precise, transformed position or
opacity value on the compositor, doesn't affect those results.
The first test case for CSS animations and the first test case for CSS
transitions in this patch fail without this fix.

For now, we are going to make _all_ CSS Animations related timer fuzzing
only applicable in Resist Fingerprinting Mode (addressing the last couple
that had not already been configured that way.)
We hardcode their content mix-ins as zero, but leave comments indicating
how they should behave.

Now we sort CSS animation/transition events by scheduled event time prior
to compositor order.
SortEvents() will be a private method in the next patch in this patch
series.

Now single AnimationEventDispatcher can handle both CSS animation/transition
events simultaneously. To do this we had to change AnimationEventInfo and
TransitionEventInfo into a single struct, the struct is also named
AnimationEventInfo.
It results we can sort both CSS animation/transition events altogether. Thus
we make sure CSS animation/transition events are sorted by scheduled event time
prior to their composite order (i.e. transitions is prior to animations).
At this moment, we don't sort both events altogether since nsAnimationManager
and nsTransitionManager has an AnimationEventDispatcher respectively. In the
next patch we move AnimationEventDispatcher into nsPresContext, i.e. each
document has an AnimationEventDispatcher without the distinction between
CSS animations and transitions.
Note that, after this patch, we copy all members in InternalTransitionEvent and
InternalAnimationEvent in the copy-constructor of AnimationEventInfo, this
will be fixed once WidgetEvent has move-constructor and move-assignment
(bug 1433008).

We don't need to create AnimationEventParams, we can direcly create
AnimationEventInfo array and move it to dispatcher.

This reflects the change made to the Web Animations specification in:
9e2053f5531c3415f4cc
(I got it wrong the first time. The second commit fixes the first.)
And discussed in:
https://github.com/w3c/web-animations/issues/196
In summary, we are splitting the "pending" play state out into a separate
boolean member so that it is possible to distinguish between "play-pending" and
"pause-pending" and because most of the time when you check for
animation.playState === 'running' you also really want to include play-pending
animations.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

This allows Gecko to use the same criteria as Servo for evaluating if a property
should be transitioned and will cause Gecko to exclude discretely animated
properties, including, in future, the 'display' property.

I've chosen this approach mainly because there's no other good way to guarantee
the model is correct than holding the snapshots alive until a style refresh.
What I tried before this (storing them in a sort of "immutable element data") is
a pain, since we call into style from the frame constructor and other content
notifications, which makes keeping track of which snapshots should be cleared an
which shouldn't an insane task.
Ideally we'd have a single entry-point for style, but that's not the case right
now, and changing that requires pretty non-trivial changes to the frame
constructor.

We will use this type later in this patch series in nsSMILCSSProperty so this
patch moves it to a separate file so it can be re-used.

We use ServoComputedStyleValues as the argument here, instead of
ServoComputedValues, because I will use template for nsStyleContext and
ServoComputedValuesWithParent in UpdateTransitions() and
ConsiderInitiatingTransition(). Besides, add an FFI to check if a
proeprty is discrete animation type.

We have different interpolation implementations on Gecko and Servo, so
wrap the "Can be Interpolated" in AnimationValue. This patch also introduces
the FFI, Servo_Animationvalues_IsInterpolable.
MozReview-Commit-ID: 92Yf1u84A3c
We also need to update the interpolation code based on ServoAnimationValue in
ElementPropertyTransition::UpdateStartValueFromReplacedTransition().
Therefore, ElementPropertyTransition can be used by both Gecko and Servo.
MozReview-Commit-ID: BrIpvRR3te8
Use AnimationValue as arguments, and add one FFI to uncompute the
value. Therefore, we can use GetTransitionKeyframes for both Gecko and
Servo backends. However, there are many "mGecko"s, which will be removed
later.
MozReview-Commit-ID: Dg5hrDdlIWb
GetTransitionKeyframes is a simple helper function, which is only used by
ConsiderInitiatingTransition, so let's make it static to reduce the time
to revise the header.
