This changes CreateClippedDrawTarget so that instead of taking
a max size and a transform it just takes a user space rect of
the desired bounds.
This change allows the caller to not worry about the computing
a max size based on the current clip. Instead this responsibility
is lowered into the specific backends.
The main motivation for this work is to allow blob recoordination
to create recordings that don't depend on the current clip.
Some additional benefits are that the API is easier to use and
as can be seen simplifies the SVG masking code because it doesn't
need to track surface offsets manually.
It's also an important step towards removing all the uses of
gfxContext::GetClipExtents which will let us get rid of the separate
clipping stack in gfxContext and help us move off of gfxContext
completely.
Most backend implementations of CreateClippedDrawTarget are relatively
simple. DrawTargetCapture is modified to track the current clip rect
so that it can create a new DrawTargetCapture of the appropriate size
without needing to worry about lazy resolution.

This fixes a situation where a Device Reset occurs during initialization, after mDC has already been created but before mBitmap is created. In this case IsValid and EnsureInitialized would previously return 'true' in subsequent calls, since they were only checking for the DC.
This patch makes us properly store the full result of initialization for checking with IsValid and re-runs of EnsureInitialized.

Badly-behaved consumers of DrawTargetRecording can trigger recording of
draw calls that will fail to allocate required draw targets when the
recording is replayed. This patch tries to guard against this by
detecting these situations at record-time rather than crashing at
replay-time. When such a situation is detected, it will crash (for
content processes, to catch such scenarios) or gracefully fail (for
other processes).

Rendering glyphs at many different rotations was causing the D2D glyph
cache to grow very large. Calling EndDraw/BeginDraw will prune the
cache, but is costly, so only do it for every 1000 glyphs.

This patch takes the safest route for securing modifications to the dependency graph for D2D DrawTargets. It's possible a slightly optimal approach is possible, however lock contention should be rare and I believe this is the safest and most upliftable approach.

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.

This introduces the infrastructure to specify the bounds of drawing commands being executed. These bounds can then be used to limit operations done for blending in order to reduce required fillrate. Currently we only specify the bounds for DrawSurface but it would be easy to extend this for other drawing commands if so desired.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.

This conversion was done with the script:
find . -name '*.cpp' -o -name '*.h' -o -name '*.mm' -o -name '*.idl' | \
egrep -v 'cairo-win32-refptr.h|RefPtr.h|TestRefPtr.cpp' | \
xargs sed -i -e 's/mozilla::TemporaryRef</already_AddRefed</g' \
-e 's/TemporaryRef</already_AddRefed</g'
Manual fixups were performed in the following instances:
- We handled mfbt/RefPtr.h manually so as to not convert TemporaryRef itself
into already_AddRefed.
- The following files had explicit Move() calls added to make up for the lack
of a copy constructor on already_AddRefed:
dom/base/ImageEncoder.cpp
dom/media/MediaTaskQueue.{h,cpp}
dom/media/webaudio/PannerNode.cpp
- A redundant overload for MediaTaskQueue::Dispatch was deleted.
- A few manual fixups were required in mfbt/tests/TestRefPtr.cpp.
- Comments, using declarations, and forward declarations relating to
TemporaryRef in dom/canvas/ and gfx/layers/ were changed to refer to
already_AddRefed.
This patch lets us repush all layers with their backgrounds copied when drawing subpixel AA'ed text to a transparent surface. This can be wasteful since the last layer that was pushed could already have had its pixels where the glyphs will be drawn made opaque, however we have no way of knowing this so we have to always repush the layers.
