The flag of force update is only for fallback items. Fallback items can't share the images with other items.
So I replace 'aForceUpdate' with 'aFallback' and remove some unnecessary checks.

This commit reverts DoubleBufferedContentClient to creating a back buffer
if there is an existing front buffer. This reverts back to a sequence of a
finalize frame, unrotate, and initialize new back buffer. When we are
not async painting we do each buffer operation immediately. If we are
async painting, then we collect all of the buffer operations and perform
them on the paint thread.
Note on locking: The destination for buffer copies must always be opened
with the async write flag, and the source must be unlocked.

This adds the code that APZ needs to use the WR hit-testing API. For now
(if the pref is enabled) it just does the hit-test and compares the
result to the regular hit-test, printing out discrepancies. It also
doesn't yet get the scrollbar result.

These days (at least with webrender enabled), the layers id is created
by mashing together two uint32 values into the uint64. Printing it as in
base 10 produces some large number near the 32-bit boundary, and it's
much more legible/easier to compare when printed in hex.

This commit removes the `layers.omtp.force-sync` preference and replaces
it with a preprocessor define that is commented out. This commit also
changes the behavior of force-sync so that it also does synchronization
with CompositorBridgeChild like normal OMTP. This simplifies the code
and makes using a preprocessor define easier.

This patch implements HTMLMediaElement::GetEventTargetParent and set
aVisitor.mCanHandle to false to mouse/touch/pointer events, when
the media control is present. This tells the event dispatcher that
these events are supposed to be handled exclusively by the
videocontrol binding within the media element, and should not
dispatch nor consumed by the content.

This helps us avoid rerasterizing the blob images every frame. This makes a
huge difference in performance. Our score goes from approx 75 to 380. Current
Firefox gets about 200.
The core of this change is in gfxContext.*:
- change gfxContext::CurrentMatrix() and gfxContext::SetMatrix() to
return and take a Matrix respectively, instead of converting to
and from a gfxMatrix (which uses doubles). These functions therefore
will now match the native representation of the transform in gfxContext.
- add two new functions CurrentMatrixDouble() and SetMatrixDouble() that
do what the old CurrentMatrix() and SetMatrix() used to do, i.e.
convert between the float matrix and the double matrix.
The rest of the change is just updating the call sites to avoid round-
tripping between floats and doubles where possible. Call sites that are
hard to fix are migrated to the new XXXDouble functions which preserves
the existing behaviour.

This commit adds a CapturedBufferState which is used to record all the operations
that are necessary for preparing the buffers. The commands are then instantly
executed to preserve the same behavior, but in the following commit they will
be dispatched to the paint thread.
Note: RotatedBuffer's aren't thread safe and so a shallow copy needs to be made
for sending to the paint thread. This complicates the code for AdjustTo as it can
fail naturally and the buffer parameter changes are needed later in BeginPaint.
So the code for AdjustTo is split up a bit to accomodate that.

To sync the back buffer with the front buffer, we set the back buffer rect and
rotation to the front buffer's, and then copy over the pixels that different.
We used to do the updating of the rect and rotation before BeginPaint, but that
isn't necessary and we can move it to be with the copying of pixels.

This commit is an optimization for double buffering that delays the creation of
a back buffer until we know what kind of content type it needs to be.
Before this commit, we would EnsureBackBufferIfFrontBuffer before BeginPaint,
then in BeginPaint we could determine that we actually needed a different kind
of buffer because the content changed type, and recreate it.
This was needed because BeginPaint would copy the old front buffer to the buffer
created by EnsureBackBufferIfFrontBuffer, and then if anything failed or we had
determined we couldn't reuse the buffer, we would create a new one and copy that
"temporary" back buffer over, and use the new one.
This is unnecessary because we only need read access on that "temporary" back
buffer, and so we can just use the current front buffer instead.
This optimization only affects the double buffered case, and the single buffered
or basic cases should remain the same.
Note: Because we now need the front buffer for copying into the new back buffer,
we cannot Clear() it away in some error cases.
Note: The code in FinalizeFrame assumes that the back and front buffer have the
same size. This was implicitly enforced before, and now needs to be explicitly
enforced. This commit tries to preserve the exact same behavior, although the
restriction should be removed as long as the back buffer is large enough for
the visible region.

As with the previous patch, instead of setting the override on the root
layer, we set the flag on the nsDisplayListBuilder before building the
display list, and the flag automatically forces all event regions
display items to use their dispatch-to-content region instead of any
other regions.
Both the WebRender and non-WebRender codepaths were setting the override
flag on their root layers and don't need to any more.

There are cases where we do a main-thread paint at a scroll position
where sticky offsets have been applied in order to keep sticky items
visually unmoving. From that paint, it's possible to do an async-scroll
in the direction that reduces the sticky offset. In order for WR to
handle this case properly we need to tell WR how much of a sticky offset
was already applied on the main thread.

There are up to two compositor threads spawned - one in the GPU process
and one in the UI/chrome process. If the GPU process is used, then
failing to start the UI compositor thread is not fatal -- unless the GPU
process crashes too much and we fallback to the UI/chrome process. If
the GPU process compositor thread failed to start, then the GPU process
will crash and either restart, or fallback to the UI/chrome process
thread. If both fail, then Firefox crashes as expected.
Before we would not setup a content process properly unless the
UI compositor thread was active, even when using the GPU process. Now we
do, which allows the browser to be fully functional. Additionally when
shutting down, we ignore the lack of a compositor thread to permit a
graceful shutdown. In a future patch we will ideally we would not spawn
the compositor thread in a process until we actually need it, and
release assert on its failing to start.
Currently, the device-reset flow doesn't notify the decoder for device change
immediately. The decoder might use an invalid sync-object for synchronization.
Then, we will hit some assertions.
This patch try to make the synchronization flow become fallible, then we could
pass the error to the media framework for error handling.
