WebAudio is adding a suspend()/resume() API:

https://github.com/WebAudio/web-audio-api/issues/361
https://github.com/WebAudio/web-audio-api/issues/317

In more detail, here is the proposed additions to the spec:

New attribute "state" with values:
paused
  Currently paused (time is not proceeding, audio hardware may be powered down/released).
running
  Audio is being processed.
released
  AudioContext has been released, and can no longer be used to process audio. All system resources should be released.

void suspend()
Suspends the progression of time in the audio context, allows any current buffer contents to be played to the destination and then allows the system to power down and/or release audio hardware. If the context has been released, an InvalidStateError MUST be thrown. This is generally useful when the application knows it will not need the AudioContext for some time, and wishes to let the audio hardware power down.

While the system is suspend, MediaStreams will have their output ignored; that is, data will be lost by the real time nature of media streams. HTMLMediaElements will similarly have their output ignored until the system is resumed. Audio Workers and ScriptProcessorNodes will simply not fire their onaudioprocess events while suspended, but will resume when resumed. For the purpose of AnalyserNode window functions, the data is considered as a continuous stream - i.e. the resume()/suspend() does not cause silence to appear in the AnalyserNode's stream of data.

Promise resume()
Resumes the progression of time in the audio context, which may involve re-priming the frame buffer contents. The promise resolves when the system has re-acquired (if necessary) access to audio hardware and has begun streaming to the destination, or immediately (with no other effect) if the context is already running. The promise is rejected if the context has been released.

Currently, first letter renderers are created and destroyed through the updateFirstLetters() call in
RenderBlock. This has, historically, been problematic as we may miss places where the call
was required, leading to accessing invalid memory.

This CL converts the first letter code to use a PseudoElement for the first-letter instead of
creating classes during layout.

With the PseudoElement implementation the two tests which are currently in
LayoutTests/fast/css/first-letter-removed-added.html work as expected.

treat ISO-8859-1 and windows-1252 synonymously. Moreover, windows-1252
is the canonical encoding name.

spec.

When a render object changes location, we should force paint
invalidation checking for all descendants on the same backing,
including positioned ones. However, previously we only force
invalidation checking for non-positioned descendants.

Now let RenderBlock override
RenderObject::invalidatePaintOfSubtreesIfNeeded() so that it
can use the childPaintInvalidationState, which has been forced
checking of invaldation, for the positioned descendants.

The plan is to create a LocalFrame that is loosely tied to an existing RemoteFrame but is not really attached to the FrameTree. The LocalFrame will begin loading, and when it commits, it will be swapped into where the RemotFrame was. This adds sufficient logic to actually support that swap (and to maintain the intermediate semi-attached state while the LocalFrame is provisional).

beginLayer()/endLayer() behaves like save()/restore() for only CTM and clip states.
SkCanvas::saveLayer() behaves the same as save(), but in addition it allocates an offscreen buffer.
It causes the inconsistency for restoring states managed by between SkCanvas and SkPaint.

For example,
    context.translate(1, 0);
    context.setCompositeOperation(CompositeDestinationIn);

    context.beginLayer(1, CompositeSourceIn);
    context.translate(-1, 0);
    context.setCompositeOperation(CompositeSourceOver);
    context.endLayer();

    // At this moment, CTM is translate(1, 0) while current composite operator is CompositeSourceOver.

It's because CTM is managed by SkCanvas, while current composite operator is managed by GraphicsContext.

https://codereview.chromium.org/620553009 moved
the selection to invalidate-after-compositing-updates,
except that it lied and we still do some invalidations
on the spot. This is needed as we don't store the old
selection information so we can't generate the old
selection invalidation rect later.

This change just generates the invalidation on the spot
for block selection gaps (like we do for normal selection).

The long-term fix will be to store the old rect but it requires
more thoughts and we need some quick fix for this nasty issue.

Start supporting style invalidation for selectors containing ::content,
but still use SubtreeStyleChange on distributed children of the content
element.

If you have a selector ".class ::content .target", we will not invalidate
the whole subtree for the element matching ".class", but do style
invalidation for elements matching ".target". We will not cross the
insertion point during invalidation at this point, but merely mark
content elements found during style invalidation with SubtreeStyleChange.

That may be done in a separate patch, but it requires the style
invalidator to have invalidation sets scheduled for elements inside a
shadow tree affect style invalidation of its host subtree.

The addition of :host-context as boundary-crossing and insertion-point-
crossing is in preparation for supporting style invalidation for the
:host-context selector.
