This patch makes three related changes:
- A non-functional change that factors a IsRecyclable function on
HitTestingTreeNode.
- A non-functional change that sprinkles proof-of-tree-lock arguments to
a few HitTestingTreeNode functions, to ensure at compile-time that they
can only be called while holding the tree lock.
- A functional change that stops clearing mLayersId in
HitTestingTreeNode::Destroy, so that if a node is non-recyclable, and
it gets Destroy()'d while other code still has a RefPtr to it, that
other code can still read the layers id off in a safe manner.
These changes provide a stronger set of checks around node recycling,
and allows for a safe mechanism to use a HitTestingTreeNode on the
controller thread without having to lock the entire APZ tree. The
mechanism is effectively a per-node lock, which will be added in the
next patch.

We can easily use Maybe<DataSourceSurface::ScopedMap> instead of
allocated the map on the heap. This does require some minor changes to
ScopedMap to properly support moves, but should be much more efficient.
This defines three flushing functions that flush different parts of the
WR pipeline. Using all three guarantees that everything sent to WR will
have been flushed. This is what we need to do in SyncWithCompositor to
ensure that it meets the API contract.
In addition, this patch updates the existing FlushRendering function to
use the new functions (no functional changes intended here).

Instead of notifying the AsyncImagePipelineManager on the compositor
thread via the CompositorBridgeParent, we can send it the new pipeline
info directly from the RenderThread after the update happens. This
effectively splits the AsyncImagePipelineManager update-processing into
two parts: one that takes in the new pipeline info and one that process
it. This allows us to invoke the processing step from other code running
on the compositor thread, which we will need to do in the next patch.

We do a silent upcast from CompositorBridgeParent* to the base class and

In order to have useful Wayland builds we need ability to switch
between GL backends run-time - to use EGL backend for Wayland and GLX backend for X11.
GL_PROVIDER_GLX is used exclusively for GLX GL backend, so let's replace GL_PROVIDER_GLX
build-time check by more general MOZ_X11 check which determines X11 dependent code
and it's valid for both X11 and Wayland builds.

In cases where we were carrying down a transform from a
nsDisplayTransform and then applying it to a child item's WRLSD, we
could get incorrect behaviour when that child item had a different ASR
(and therefore had a different APZ instance). This patch corrects that
behaviour by ensuring that when we run into this case we fall back to
creating two WRLSD items instead of one, where the new WRLSD is the
parent of the other one, and holds the transform. The child WRLSD has
the data from the child item's ASR.

The ceiling was introduced in bug 549190 for improve the consistency of
underline positioning. However, removing ceiling now doesn't seem to
regress the testcases in that bug, probably thanks to improvement in
other part.
The ceiling here causes us to have different font metrics than other
browsers on Windows, and can lead to webcompat issue. We also don't do
this for other backends. So it's probably better removing it in favor
of rounding.
There are several test changes:

fix it in a platform-independent way.

With non-WebRender, the composite is triggered unconditionally when we receive
the transaction from the content side, so we never needed this. The previous
patch adds the composite for the equivalent WebRender codepath, but it's better
to do it explicitly in NotifyLayersUpdated as well. The reason for this is that
with WebRender, this code runs on the updater thread which is not the same as
the compositor thread - so the composition that is scheduled from
WebRenderBridgeParent upon receiving the transaction might happen before the
scroll offset update is actually applied. Triggering a composition from
NotifyLayersUpdated should be a no-op in the cases where a composition is already
scheduled, but in cases where it has not been scheduled, it will schedule one
to ensure the scroll offset update gets composited properly.

there are a couple of functional changes:
- If we have scroll offset updates we now schedule a composite instead of
sending the DidComposite right away. This is needed because we want to

- If there are WebRenderParentCommands provided, we process them and update the

This is to accommodate non-networking fd usage (IPC transports, various
databases, .xpi files, etc.), so it's separate from Necko's existing
manipulation of the fd limit, which is tied into Necko's internal limits
on how many sockets it will try to poll at once.
Note that resource limits are inherited by child processes, so this needs
to be done only in the parent.
This patch also removes similar code used on Solaris and Mac OS X. The

ClientLayerManager, which updates the FrameMetrics on the client side

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.

those compositables. Otherwise, WR can try to do a scene build on the intermediate
state which results in missing pipeline errors.

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.

This is a refactoring that moves the "parent clip id" determination from
bindings.rs into WebRenderAPI.cpp. This should be functionally
identical.

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.
In addition, this is the first commit making use of cbindgen's new support
for bridging Rust enums natively into C++! This bumps our minimum cbindgen
to 6.0.0 (just released).

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).

The patch in question is not strictly necessary to fix bug 1458063, and was
causing intermittent failures.

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`.
