Even if we cannot reuse the back buffer, we still use it to initialize the new back buffer.
The correct condition for detecting changes to buffer mode should only care if there is a
buffer, not if we decided to reuse it.
If the buffer mode has changed to component alpha, we need to invalidate and repaint everything
because we won't be able to copy over content to the new buffer correctly.
I believe this is a regression from the refactoring that created this function from
RotatedContentBuffer::BeginPaint.

Add a new TextureClientData type, AndroidNativeWindowTextureData,
backed by a SurfaceTexture in single-buffer mode. It uses the
NativeWindow API, which provides producer-side access to the buffer.
This provides a DrawTarget which can be used to paint directly in to
the SurfaceTexture, which can then be composited using a SurfaceTextureHost.
Due to API restrictions it is not possible to read from a NativeWindow
while the corresponding SurfaceTexture has ownership of the
buffer. TiledContentClient now handles that by painting the additional
region that it cannot copy from the front buffer, if required.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

These items don't paint anything and are handled separately, so we don't need
to call CreateWebRenderCommands for them. We could just implement
CreateWebRenderCommands for the item and have it return true unconditionally,
but it's still an extra virtual call. Plus there's existing code in
WebRenderCommandBuilder that's conditioned specifically for event regions so
I prefer keeping all the conditioned code together.

This changes the serialization format a little bit.
We now have an index at the end of the blob. This
is currently used to store a list of the used font keys.
In the future we'll add rects and can use it for invalidation.
This extends the fix in bug 1373802 to account for extra levels of
display item nesting. If those extra intermediate display items don't
push any clips we still want to pick up the ClipAndScroll from the
enclosing ancestor that has it.

We already support cases where we have scrolling clips applied to fixed
items. However if we had to build nested clips inside those items, then
those nested clips would not properly inherit from the scrolling clips.
This patch addresses that case.

The window buttons are drawn as part of the AddWindowOverlayWebRenderCommands
function which is invoked in the full-transaction codepath. It should be possible
to have the empty transaction codepath simply update the image (without building
a full WR display list) and do a recomposite. That would be more performant but
it requires some plumbing to build and ship across a IpcResourceUpdateQueue on
empty transactions.

My original understanding of the API was flawed, and so while I had
position:sticky working in some cases it didn't work properly in a lot
of other cases. This patch corrects the usage of the API to match what

Most of this change is just fiddling with function signatures so that they take
a LayerManager* instead of a Layer* (or in some cases, both). This allows
the WebRender codepaths to pass a WebRenderLayerManager* instead of having to
produce a Layer* which it doesn't have.

Instead of unconditionally pushing and popping clips per display item,
this patch changes things so that for each recursive display list, we
create an ItemClips struct. We push this onto the stack when we enter
the display list, and pop it off at the end. For each display item, we
check to see if the clips would actually change compared to the previous
display item, and only do the pop/repush in that case.

One of the sticky-pos tests was only passing because of two wrongs that
cancelled each other out in the old code. Specifically, instead of
defining a nested clip with the sticky clip as an ancestor, the clip was being
defined with the root ASR as an ancestor. Both resulted in the nested
clip not scrolling with the actual scrolling scrollframe and so the test
was passing.
The new code changes things so that the nested clip is defined with the
actual scrolling scrollframe as the ancestor, causing the reftest to fail.
Fixing the clip ancestry is not hard but it reveals other problems so
so I'm deferring that to a follow-up bug.

Bug 1409442 is tracking a change that will allow scroll layers to have
multiple ancestors. Without that, there are cases we cannot properly
handle, and so we need to ignore a clip in those scenarios. This patch

When display items (such as mask items) push an out-of-band clip, we
can't use clip ids from, or update clip ids into, the cache. We also
need to ensure we take these out-of-band clips into account when
determining the parent for a new clip we are going to define.

This code is more straightforward in its recursion than the old code,
and provides a relatively clean way to explicitly pass the desired
parent when defining a new clip or scroll layer.
Refer to the documentation in the patch for more details.
Note that this patch provides the basic recursive algorithm to define
the clips and scroll layers, although it omits some of the complicating
edge cases which will be added in later patches. The new code is not
invoked from anywhere until all the edge case handling has been done.

From the crashes associated with bug 1389021, we know that some
compositor thread IPDL owners are not being cleaned up properly. We do
not know which protocols are causing the problem, so we temporarily will
annotate the logs with the ownership status. This should be limited to
under a dozen instances of the protocols.
This change will be backed out after a few builds are produced with it
and we see the first crash reports with the relevant data.
