All animated images on a page are currently registered with the refresh
driver and advance with the tick refresh. These animations may not even
be in view, and if they are large and thus cause redecoding, cause a
marked increase in CPU usage for no benefit to the user.
This patch adds an additional flag, mCompositedFrameRequested, to the
AnimationState used by FrameAnimator. It is set to true each time the
current animated image frame is requested via
FrameAnimator::GetCompositedFrame. It is set to false each time the
frame is advanced in FrameAnimator::AdvanceFrame (via
FrameAnimator::RequestRefresh). If it is true when
FrameAnimator::RequestRefresh is called, then it will advance the
animation according to the normal rules. If it is false, then it will
set the current animation time to the current time instead of advancing.
This should not cause the animation to fall behind anymore or skip
frames more than it does today. This is because if
FrameAnimator::GetCompositedFrame is not called, then the internal state
of the animation is advancing ahead of what the user sees. Once it is
called, the new frame is far ahead of the previously displayed frame.
The only difference now is that we will display the previous frame for
slightly longer until the next refresh tick.
Note that if an animated image is layerized (should not happen today) or
otherwise uses an ImageContainer, this optimization fails. While we know
whether or not we have an image container, we do not know if anything is
actively using it.
We no longer need them since in the previous commit we make sure subsequent
ticks happens for animations in delay phase.

If the animation is in delay phase, we shouldn't produce any values for the
animation but we have to make sure subsequent ticks happen in order to the time
when the animation starts. So what we should do here is that
1) Make AnimationHelper::SampleAnimations() return boolean, return true if
there is any animation.
2) Schedule the next tick if AnimationHelper::SampleAnimations return true
This setup is equivalent to what we do non-WebRender.
So that we don't need to set non-animated value as AnimatedValue for delay
phase to make subsequent ticks happen for the delay phase animations. The
non-animated value will be dropped in the next patch.

The test case has a fixed item A inside a scrollframe B which is inside
a reference frame C which is inside the root scrollframe D. The
ClipManager code currently uses D's scrollid as the scrolling ancestor
for A, because the gecko display list's ASR is set up that way. However,
we really want to set C as the scrolling ancestor, because otherwise the
item A gets hoisted out of C and the transform from C doesn't get
applied to it. This patch ensures that when we enter C, we install an
override so that anything that would have used D's scrollid ends up
using C's, which results in the correct behaviour.

The clip chain API in webrender allows us to build the clip state in WR
so that it matches the gecko display list more closely. This patch throws
away ScrollingLayersHelper.* and introduces ClipManager.* which pushes
the clip state to WR using the new method. A quick summary of the new
method is below.
Each display item in gecko has a DisplayItemClipChain which is a chain
of individual clips. The individual clips are defined in WR, and the
clip ids for those clips are put into a WR clip chain using the new
define_clip_chain API. Furthermore, each clip chain can also have a
parent chain, which is used to link a DisplayItemClipChain to the parent
display item's DisplayItemClipChain. This allows the WR clip state to
closely match the structure of the gecko display list clip state,
resulting in more correct behaviour.
There are a few other major changes that are lumped into this patch and
that were tricky to separate into their own patches:
- The collapsing of WrScrollId and WrStickyId into WrClipId. On the WR
side all the clip ids are treated the same anyway. Trying to preserve
the arbitrary distinction on the gecko side was resulting in
increasingly convoluted code, with different kinds of Variant<..>
types in the method signatures. It was much simpler and resulted in a
bunch of code deletion to just collapse the types.
- Moving the "override" mechanism from WebRenderAPI to ClipManager. The
override mechanism (explained in ClipManager.h) was simplified by
moving it into ClipManager, because it removed the need for tracking
additional clip stack state in WebRenderAPI.

MayResample() is used on the content and compositor to determine whether the whole
visible region should be or should have been validated. This calculation is done
partially by traversing ancestor layers and looking for a flag. This can return
different values then in the content side versus the shadow side, which in this
case leads to artifacts.
This commit tries to solve the problem by ignoring layers that content is unaware
of. This works, but has the downside that resampling artifacts could show up if
the parent process is truly doing animations that require resampling.

When a transform thinks it's animated we should abandon screen rasterization
and instead favour local rasterization. This produces a more visually
pleasant rendering, as pixel-snapping "wobbles" the text between
frames.
The float scale of GlyphRasterSpace::Local is currently unused, but this
PR tries its best to set it to a reasonable value, based on discussion
with glennw about the intended semantics. We agreed it should specify
the scale *relative* to the parent stacking context, which means it's
just whatever scaling the stacking context's transform applies. It's
possible we'll need to clamp this value or make it properly 2-dimensional
later on.
Some book-keeping is added to StackingContextHelper to ensure that
GlyphRasterSpace::Screen is never requested by a descendent
of a stacking context using GlyphRasterSpace::Local.
nsDisplayMask is changed to use a StackingContextHelper to ensure
rasterSpace is properly propagated.

The original code was added in bug 385263 for fixing bug 279032 that a
single font provides zero for max ascent / descent in its HHEA table
which caused Firefox to crash.
Unconditionally picking the maximum of max ascent / descent and their
em correspondents doesn't seem to be essential for working around that
case, so this patch changes it to just use the em ascent / descent when
both max ascent and descent are zero.
This fixes a webcompat problem related to Roboto font on Linux (and
presumably also Android given it uses FreeType backend as well).

On windows it's possible for us to fallback from D2D to Skia rendering at any time due to a device reset.
If this happens with `enable-tiles-if-skia-pomtp` enabled we could begin to use tiling. This can cause a
crash if we never created the worker threads because at initialization time we weren't using tiling.
Another way to fix this would be to dynamically create the worker threads in UpdateRenderMode if we
have switched to skia. That's a larger change and more might be required, so I'd rather just fix the
crash for now.
This commit also fixes a pref that should be `Once` instead of `Live`.

The purpose of the previous timestamp is to reduce the time difference between

This rearranges how synthetic-bold use is determined in the font selection
& rendering code. Previously, we would decide during the font-selection
algorithm whether we need to apply synthetic-bold to the chosen face, and
then pass that decision through the fontgroup (storing it in the FamilyFace
entries of the mFonts array there) down to the actual rendering code that
instantiates fonts from the faces (font entries) we've selected.
That became a problem for variation fonts because in the case of a user
font, we may not have downloaded the resource yet, so we just have a "user
font container" entry, which carries the descriptors from the @font-face
rule and will fetch the actual resource when needed. But in the case of a
@font-face rule without a weight descriptor, we don't actually know at
font-selection time whether the face will support "true" bold (via a
variation axis) or not, so we can't reliably make the right decision about
applying synthetic bold.
So we now defer that decision until we actually instantiate a platform font
object to shape/measure/draw text. At that point, we have the requested
style and we also have the real font resource, so we can easily determine
whether fake-bold is required.
(This patch should not result in any visible behavior change; that will
come in a second patch now that the architecture supports it.)
With async scene building, we might get the message to delete certain
compositor animation ids while we are still building and rendering
scenes that have those compositor animations. This patch associates
those ids with the epoch at which they are safe to delete, and only does
the deletion once we have rendered that epoch.

Before this change, the value which was set by SetShadowBaseTransform()
has been used for the assertion, but it is possible that the value is changed
by APZ. And it's hard to tell whether the value has been changed by APZ or not
and it's hard to *reverse-calculate* the differences in the past APZ at the
moment we want to do the assert.
So after this patch, on debug build we don't actually skip the calculation for
unchanged animations and use the newly calculated value for the assertion.

The FlingPhysics controls the shape of the fling curve, including how fast
and far it goes, while leaving other logic (related to flywheel, handoff,
overscroll, etc.) centralized in GenericFlingAnimation.
FlingPhysics is a template parameter of GenericFlingAnimation because we

The calculation in that function is specific to a particular physics model,

There's a circular dependency between `UsesTiling` and `InitOMTPConfig` because
we try to disable OMTP if we will be using tiling and edge padding is enabled.
Now that edge padding is disabled everywhere except android it should be safe

with `edge-padding` being enabled on windows because it wouldn't be defined in all.js and defaulting

since the other animation might be 'accumulate' or 'add', or might have a
missing keyframe (i.e. the calculated animation values will be used in the
missing keyframe).

In the next patch, we skip updating animation value for the layer if the
animation value isn't changed. So without this patch, we will have to update
animation value even if the value isn't changed at all.

We don't need to calculate TimingParams each time we compose an animation on
the compositor because TimingParams is immobile since the animation was sent to
the compositor.

On the testing refresh mode, we shouldn't update mPreviousFrameTimeStamp and
don't need to use it since there shouldn't have any time difference between
compositor time stamp and main-thread time stamp on the testing mode.

These tasks have an implicit ordering with other tasks that are
dispatched from the compositor thread to the updater thread, and so they
need to be bounced through the updater thread before we run them on the
controller thread.

ScrollbarData::mDirection is set for both kinds of scrollbar layers.

This is possible if we just let the APZUpdater know during construction
if WR is enabled or not, and that information combined with the pref
will allow it to know whether to use the scene builder thread task queue
or just use the compositor thread as the updater thread.

We wrap the std::unordered_map in a StaticAutoPtr so that there's no
initialization cost, and also so that we have a smaller memory footprint
in processes that aren't using WebRender+APZ.

This has a big performance impact because we instead of defaulting to the bounds
of the image we can use a much smaller temporary surface.

Two AnimationValue are still used in AnimationPropertySegment since the
AnimationPropertySegment is used in compose_animation_segment() which is also
invoked on the main-thread, so we will fix it later in a bug that will drop
AnimationValue usage on the main-thread side.

This makes the APZ sampler thread be the render backend thread whenever
webrender is being used (not just when async scene building is enabled).

When sampling APZ transforms from rust code, we will need a timestamp at
which to sample the transforms. It's not obvious what the right
timestamp is to use here, and this will almost certainly be revisited
when we are hooking up OMTA in bug 1453360. For now we just stash the
most recent composite timestamp on the APZSampler and use that when
sampling. This seems to work fine.

The TransactionBuilder class comes with a bunch of baggage (it
automatically allocates/deallocates a transaction under the hood) which
we will want to avoid for the RB callbacks into APZ. This patch adds a
lightweight TransactionWrapper class that APZ can use to provide the
async transform info and that will be simpler to use in the callback
from rust code.

Deferred tasks currently run as part of the sampling process, in
AdvanceAnimations. However, deferred tasks also sometimes need to acquire
the APZ tree lock for stuff. Acquiring the tree lock is not going to be
allowed on the render backend thread (which is the sampler thread when
WR is enabled), so we need to bump these tasks to another thread. The
controller thread is safe for this purpose.

For webrender, we need to be able to sample the async transforms from nodes
and thumbs without holding the tree lock, since the sampling happens on
the render backend thread, and holding the tree lock would be a
threading violation. We can use the mApzcMap to sample the node
transforms, but for the thumbs we need to introduce another data
structure. This data structure packages up all the information from
the HitTestingTreeNodes that we need for the computation and stores it
protected by the map lock. This allows us to compute the transforms
safely while just holding the map lock.

This lets the APZSampler know which thread is the actual sampler thread.
This is only really used for the thread assertions, but might be useful
for debugging and such as well.
Note that since this behaviour is not dependent on any prefs (unlike the
updater thread, which is only the scene builder thread when the async
scene building pref is enabled), we don't hook it up to the rust code
just yet; that will happen in the last patch.
