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.

It's a really minor perf improvement, but also a cleanup IMO.
Also be a bit more const-correct while at it.

We defer ParentCommands when they come in attached to a display list,
but we forgot to defer them when they're sent directly. This was
causing us to crash when we defer updates that register textures
and the content process then suddenly decides we need to delete the
textures and only tells us through RecvParentCommands. We have no
idea what the textures are yet, so we need to defer these commands
along with everything else so that it's processed in the intended order.

I replaced the values with -moz-inline-box in the crashtests
rather than removing them. I think they are still valuable
after replacing the display value.

Previously, additional dependencies (such as opacity bindings and
transforms) were stored in a simple hash set, which meant they
could not be correlated with primitive bounding rects (and thus
could not be used to derive dirty rects of a tile).
Now, by scanning the primitive list which contains the bounding
rect, we can also find additional dependencies for that primitive.
This will be used in future to create exact dirty rects (for
debugging / regression testing) and allow us to generate a
dependency descriptor for a split or merged tile from an existing
descriptor.
This patch also fixes a case where opacity bindings could result
in unnecessary invalidations, by retaining the opacity bindings
state across display lists.

ScreenPixels would be a more appropriate unit. But inside BasicCompositor everything
is in the same coordinate space anyway so we're not getting much benefit from the
units. This patch eliminates a lot of .ToUnknown*() calls.

The null is unnecessary because mDrawTarget is already null-checked above:
If mTarget is non-null, then mDrawTarget = mTarget so mDrawTarget is non-null.
If mTarget is null, then we would enter a branch that had another null check
for mDrawTarget.
As for the assertion: When rendering to an external target (reftests),
LayerManagerComposite always sets the invalid region to the entire window, so it
should never be empty here.

There was an interesting "ExpandToEnclose(IntPoint(0, 0))" call in
CreateRenderTargetForWindow that snuck in some surprising behavior that this
change makes a bit more visible.

In the past, BeginFrame would clip mDrawTarget to the invalid region and then have
CreateRenderTargetForWindow clear a rectangle. So it was effectively clearing a
region, but only if BeginFrame's region clip happened to be set on the correct
DrawTarget. In the case where a back buffer was used, this was not the case:
The clip would be on mDrawTarget but the clear would happen on the back buffer
draw target. So we were clearing more than necessary.
Now we limit clearing to the invalid region even if a back buffer is used.

On Windows, where the DrawTarget is rewrapped in a Cairo/pixman DrawTarget,
this will now cause Cairo/pixman to be used for the clear.

This seems to make a big difference when running tests with WARP.
e.g. Assertion failure: frameInfo.mDocFramesSeen == frameInfo.mDocFramesTotal,
at z:/build/build/src/gfx/webrender_bindings/RenderThread.cpp:303
and various other browser chrome test failures.
The original problem that added this flag only impacted AMD hardware as I
recall and we are unlikely to ever be running on WARP in production anyways.
When WARP is forced we also don't disable INTERNAL_THREADING_OPTIMIZATIONS.
