In MultiTiledContentClient we can create a DrawTargetTiled with a
different origin than the layer we are painting. We must therefore
ensure when edge-padding that we provide the valid region in the draw
target's device-space rather than layer-space. Not doing so was
causing us to pad out in incorrect directions, causing visible seams.

This commit exposes a method on DrawTargetCapture to see if it has
captured any drawing commands. This allows us to not dispatch
paint tasks if they will do nothing.
Ideally these tasks would execute instantly on the PaintThread, and
we would never delay sending the layer transaction or block on the
next paint, but with thread starvation and context switches it's
best to just not send them.

This commit adds the ability to create a different kind of DrawTargetCapture which
has a limit on the size of which its CaptureCommandList can grow before it is
synchronously flushed to its destination DrawTarget.
Special care is taken to not do a sync flush until we would need to resize
the backing store of the CaptureCommandList. This allows us to not waste
memory we've already allocated.
The async painting content clients are updated to use it, and get a default
value from a new preference.

This commit moves ContentClient from creating a CapturedBufferState for
buffer operations, to performing all of those operations on the
DrawTarget(Capture). Creating a DrawTargetCapture is now performed
by the RotatedBuffer when we BeginPaint, all operations are performed
on this capture, and then it's returned to the ClientPaintedLayer
as a PaintTask.
This commit is an involved refactoring of ContentClient and RotatedBuffer
to get this all to work. Here are the major parts:
1. RotatedBuffer is refactored to always perform operations on a single
DrawTarget, which may be a single DT, dual DT, or capture.
2. RotatedBuffer adds BeginCapture and EndCapture methods to switch
which DT is used in operations
3. ContentClient uses the RB capture methods when we are async painting
4. CC::BeginPaint is refactored to only perform capturing on a single
RotatedBuffer. This is because we can't have the output of one
PaintTask be the input of a different PaintTask due to the design
of the Snapshot API.
a. This can occur, today, by doing a FinalizeFrame only to later
fail to Unrotate the buffer, causing a new RB to be created
and painted into
b. The previous PaintThread code worked because it used the
buffer operations which didn't use Snapshot's
c. This is fixed by not doing FinalizeFrame on a buffer if we
realize we cannot unrotate it, and switching to initializing
a buffer using the front buffer which should be up to date.
d. I don't like touching this code, but it passes reftests,
might be a performance improvement, and I've tested it on
known regressions from the last time I messed up this code.
5. CC::PrepareForPaint is inlined into BeginPaint because dual draw
targets can be cleared correctly from a previous commit
6. The code paths in ClientPaintedLayer are unified because we no
longer need to special case this beyond setting the correct
ContentClient flag.
7. CapturedPaintState and CapturedBufferState are removed in favor
of PaintTask. Additionally EndLayer is no longer needed as all
quadrants of a rotated buffer are in the same capture, so we
don't need special case flushing code.

This commit adds a buffer unrotate operation to DrawTarget. It's
initially implemented with LockBits in DrawTarget. DrawTargetDual
overrides the implementation to pass on the operation to it's
DrawTargets.
No override is given for DrawTargetCapture as we intentionally
avoid this code path when async painting as it can fail.
This is needed so that RotatedBuffer can expose a single DrawTarget,
which can be a DrawTarget (for normal alpha), DrawTargetDual (for
component alpha), or DrawTargetCapture (when async painting).

This commit adds the ability to create a SourceSurfaceDual directly,
instead of only from a DrawTargetDual. This allows SourceRotatedBuffer
to expose itself as a single SourceSurface for a later commit.

This commit changes the behavior of DrawTargetDual::Clear to be aware that
it has on-white and on-black buffers, and perform clearing appropriately.
This is slightly against what the DrawTarget documentation says the method
should do, but it allows us to move another paint thread operation into
DrawTargetCapture and simplify our ContentClient implementations.
I haven't seen any obvious breakage with this, and reftests are green.
An alternative would be to add a separate Clear method with documented
difference here.

This commit adds an operation to perform 'edge padding' on a draw
target. By default this is performed using LockBits, but it's
overriden in DrawTargetTiled and DrawTargetCapture to propagate
the call so it functions correctly.
This helps TiledContentClient move from applying this operation
on a per texture client basis, to being able to do it on the
DrawTargetTiled after painting. This in turn helps move all
paint thread operations into DrawTargetCapture.

This lets us avoid filtering the entire source image when we only need a small portion of it.
This makes a big performance difference with tiled blob images with WebRender.

This adds a DrawTargetOffset which is basically a simplified
DrawTargetTiled that only supports one tile. It useful for situations
where Cairo's device offset was used previously.
This also replaces WebRender's use of DrawTargetTiled which was just trying to
apply offset.

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.

For example, if we set a transform to rotate3d(0, 0, 1e50, 45deg), the
expected normalized rotate axis is (0, 0, 1).
However, the length is larger than the maximum of float, so the actual value is
(0/inf, 0/inf, 1e50/inf) == (0, 0, 0). Therefore, we scale the vector before
doing normalization to avoid getting a zero vector.
