It looks like a big patch but it's mostly just moved code, with some duplication:
- Layer creation and destruction moves to LayerManagerComposite and RendererOGL.
- BasicCompositor IOSurface setup code moves to BasicCompositor.cpp.
- OpenGL IOSurface setup code moves to CompositorOGL and RenderCompositorOGL.
The duplication is a bit unfortunate but the LayerManagerComposite code will
diverge from the WebRender code soon.
BeginFrame gets a new argument aNativeLayer. This argument will go away again
over the course of this patch queue. But for now, BeginFrame is the best place
to do the layer setup because it's a very close place to PreRender which is
where that code was previously.
I wasn't able to think of a nice way to give CompositorOGL and BasicCompositor
platform-specific behavior without #ifdefs. So now LayerManagerComposite uses
the "cross-platform" NativeLayer interface, but CompositorOGL and
BasicCompositor use NativeLayerCA because they actually need the IOSurface, and
they do that in #ifdef'd code.
Luckily, NativeLayerCA.h can be included in both .cpp files and in .mm files.

NativeLayerRoot and NativeLayer allow building up a flat layer "tree" of sibling
layers. They're created and manipulated with a synchronous-looking API, but any
changes will only be applied to the underlying native layers when ApplyChanges()
is called. This ensures that the modifications can be limited to run within a
CoreAnimation transaction, and on a thread of the caller's choosing.
In the near future I'm planning to have LayerManagerComposite create these
layers. That's the reason for the pseudo-abstracted cross-platform C++ API:
LayerManagerComposite can create and place the layers, and any painting into the
layer surfaces will happen in the compositor implementations with platform-specific
code.
For now, the CoreAnimation implementation is the only implementation. I think
the current API will let us use the same infrastructure for DirectComposite
layers on Windows, but we'll likely need to make some API modifications once we
attempt that.
The classes are threadsafe; their methods can be called on any thread and the
caller is responsible for sufficient synchronization. In reality, there are only
two threads that would have a reason to use these layers: The compositor thread
and the main thread. The main thread creates and destroys the NativeLayerRootCA,
and sometimes it calls ApplyChanges, e.g. during window resizes. It also calls
SetBackingScale. All other methods are usually only called on the compositor
thread.

RecordedTextureData records TextureData calls for play back in the GPU process.
CanvasChild and CanvasParent set up the recorder and translator.
They also help to manage the starting of translation and co-ordinating the
translation with the frame transactions.
This patch also includes other changes to wire up recording and playback.
This introduces the framework and helpers needed to do this kind of testing,
and adds a basic sanity test that ensures some basic functionality.

This commit attempts to lower the pain of modifying FrameMetrics.h.
It looks like most includes really only want ViewID or
ScrollableLayerGuid, so this commit factors them out into a separate
header. In the process FrameMetrics::ViewID is changed to
ScrollableLayerGuid::ViewID, which personally seems like a better
place for it now that we have RepaintRequest. Unfortunately that
requires a lot of places to be updated.
After this commit there are still a couple of major places that
FrameMetrics is included.
* nsDisplayList.h
* nsIScrollableFrame.h
* Layers.h
Those are going to be more tricky or impossible to fix so they're
not in this commit.

FrameMetrics is currently used in about three ways.
1. Main thread to APZ transactions
2. Storing information in AsyncPanZoomController
3. APZ to main thread repaint requests
There's overlap in the use of fields in all these use cases, but it's not perfect. In a
following commit, I'd like to change the information used for (1) to support relative
scroll offset updates. This information isn't needed for (2) or (3), so it would be
good to refactor FrameMetrics out into these use cases.
This commit refactors out (3) as it is fairly easy to do. I'd like to refactor (2) out
as well, but that is trickier. I'd like to leave that for a future followup.

This exposes methods to capture a snapshot of the SharedSurfacesParent
cache for memory reporting purposes. It yields the identifiers, image
properties and references to images mapped in the cache. This will be
used by the compositor process to list everything it has mapped into its
memory space. It will also be used by the content processes / main
process to list images that specific process had mapped into the
compositor process. This will allow us to easily identify what images
remain in the compositor process, but are missing from the surface
cache.

* TexSlot caused warnings because some TexSlot constants are unused. Since some
files under gfx/vr/ want TexSlot constants, I moved the definition to
CompositionD3D11.h. (But I didn't fix gfx/vr/ in this patch.)
* Since MOZ_ASSERT_UNREACHABLE falls through in release builds, we should
assign a value even in the `default` case instead of invoking UB. If we do
not care about UB, we should use MOZ_MAKE_COMPILER_ASSUME_IS_UNREACHABLE.

This commit adds a buffer unrotate operation to DrawTarget. It's
initially implemented with LockBits in DrawTarget. DrawTargetDual
overrides the implementation to pass on the operation to it's
DrawTargets.
No override is given for DrawTargetCapture as we intentionally
avoid this code path when async painting as it can fail.
This is needed so that RotatedBuffer can expose a single DrawTarget,
which can be a DrawTarget (for normal alpha), DrawTargetDual (for
component alpha), or DrawTargetCapture (when async painting).

This commit adds an operation to perform 'edge padding' on a draw
target. By default this is performed using LockBits, but it's
overriden in DrawTargetTiled and DrawTargetCapture to propagate
the call so it functions correctly.
This helps TiledContentClient move from applying this operation
on a per texture client basis, to being able to do it on the
DrawTargetTiled after painting. This in turn helps move all
paint thread operations into DrawTargetCapture.

There's a lot going on here, but it all fits under the idea of
being able to communicate about texture locking statuses
without spinning on IsReadLocked. This is a bit of a trade -
we could just always allocate/grab a texture from the pool,
which would put a smaller cap on the amount of time we can
possibly spend when a texture is locked. However, this eats
up more CPU and memory than waiting on the textures to unlock,
and could take longer, especially if there were a large number
of textures which we just need to wait for for a short amount
of time. In any case, we very rarely hit the case where we
actually need to wait on the sync IPC to the compositor - most
of the time the textures are already unlocked.
There is also an async IPC call in here, which we make before
flushing async paints. This just causes the compositor to
check whether the GPU is done with its textures or not and
unlock them if it is. This helps us avoid the case where we
take a long time painting asynchronously, turn IPC back on at
the end of that, and then have to wait for the compositor
to to get into TiledLayerBufferComposite::UseTiles before
getting a response. Specifically this eliminates several talos
regressions which use ASAP mode.
Lastly, there seem to be no other cases of static Monitors
being used. This seems like it falls under similar use cases
as StaticMutexes, so I added it in. I can move it into its own
file if we think it might be generally useful in the future.

This commit ports over the last remaining operation for tiling that doesn't work
on the paint thread.
The difficult part for edge padding is that it is done outside of ValidateTile
so it doesn't have an associated CapturedTilePaintState to be added to as an
operation. We need it to be in the same paint state so that it's guaranteed
to be run after painting has finished.
This commit changes edge padding to instead be decided inside of ValidateTile
and either sent to the paint thread if there is OMTP or executed right away.
