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.

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.

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.

There's no other caller that sets ReadBuffer to anything else, and GL_BACK is
the default for default framebuffers. Furthermore, this call triggers
GL_INVALID_OPERATION errors when called on a non-default framebuffer.

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.

This removes the assumption that there is a default framebuffer to read from,
in order to prepare for a world in which all rendering goes into non-default
framebuffers.
The current render target's framebuffer is already bound when this function is
called.

In the past, mFullWindowRenderTarget was updated in EndFrame, so the captured
screenshots (which were captured before EndFrame) were always one frame behind.
This affected both profiler screenshots and window recording screenshots.
This also fixes a bug with the destination offset in the call to
mFullWindowRenderTarget->mDrawTarget->CopySurface(): In the case where mTarget
was non-null, those calls would use mTargetBounds.TopLeft() as the destination
offset, which is very much unrelated to anything in mFullWindowRenderTarget.
Now the destination offset for mFullWindowRenderTarget is always zero -
mFullWindowRenderTarget->mDrawTarget's device space is the same as window space.
This patch also moves the creation of mFullWindowRenderTarget down to where we
have mRenderTarget->mDrawTarget, so that we can create a DrawTarget of a type
that can efficiently copy from mRenderTarget->mDrawTarget. I think this is
important on Windows where mRenderTarget->mDrawTarget will be the Cairo/pixman
re-wrapped DrawTarget and mDrawTarget is some kind of Windows/GDI DrawTarget.

These areas only need to be cleared in rt->mDrawTarget. Once the invalid area gets
copied over to mFullWindowRenderTarget, any cleared pixels will be copied over and
clear those pixels in mFullWindowRenderTarget.
This clear wasn't only necessary, it also sometimes cleared to much, because the
clip to the invalid region that the caller sets does not apply to this DrawTarget.
