Payloads will serialize themselves into a `BlocksRingBuffer` entry when first
captured.
Later they will be deserialized, to stream JSON for the output profile.

This works by keeping track of the previous visible rect and
computing a preserved rect by intersecting with the new visible
rect.
We force the dirty rect to be inside this preserved area.

Previously after RecvResumeAndResize() we would set a flag on the root
WebRenderBridgeParent, which in turn sets a flag on the next display list it
receives that it should be treated as a first paint. Then when that display list
is finally composited, we call UiCompositorControllerParent::NotifyFirstPaint(),
which in turn tells GeckoView to uncover the widget.
After switching tabs in GeckoView browsers, however, the root
WebRenderBridgeParent does not always receive a new display list, so the widget
would not be uncovered. Instead of waiting for the next received display list to
be composited, we simply want to uncover the widget on the next composite. To
achieve this we instead set the forced-first-paint flag on the root
CompositorBridgeParent then we call NotifyFirstPaint() during
CompositorBridgeParent::NotifyPipelineRendered().

With container scrolling, layers that are fixed wrt. the RCD-RSF are no
longer descendants of layers with RCD-RSF metadata. This allows us to remove
some code that handles this case in AsyncCompositionManager.
In particular, when ApplyAsyncContentTransformToTree() calls
AlignFixedAndStickyLayers():
- If we are currently processing a layer with RCD-RSF metadata,
AlignFixedAndStickyLayers() will not do anything (because there will be
no descendants fixed wrt. the RCD-RSF), so it doesn't matter what
transform we pass to AlignFixedAndStickyLayers().
- If we are processing a different layer, then Metrics().IsRootContent()
will be false, so GetCurrentAsyncTransformForFixedAdjustment()
simplifies to just GetCurrentAsyncTransform().
As a result, GetCurrentAsyncTransformForFixedAdjustment() (and its helper
GetCurrentAsyncViewportTransform()) can be removed, and its use replaced
with GetCurrentAsyncTransform().

Rounding in layout pixels is very close to snapping in raster pixels if
there are no transforms involved. This is why it worked most of the time
and fell flat in many edge cases. In future parts of this series, we
will trust scene building and frame building to do the heavy lifting for
snapping purposes.

their coordinate systems are the screen coordinate. So that we can tell
