MotionBlurEffect makes use of many abilities some consider to be
unnatural. Notably, it mutates the state of its subtree at render time
(gasp) to sample various time points.
Mutation triggers scene graph invalidation, which bubbles up the
ancestor chain. While we immediately revalidate the subtree, we
cannot do the same for ancestors (no full scene knowledge). This means
post-rendering, we leave some SG nodes dirty - which triggers various
debug asserts).
The easiest fix is to temporarily suppress invalidation bubbling at the
MotionBlurEffect node level (this is safe, because we always revalidate
the subtree).
Also add a post-render assert for tighter state validation.

The gist here is to use saveLayer() to create a buffer to draw each
subframe into, but not actually use it to draw anything at restore()
time, hence, canvas->clear(0). (SkCanvas sniffs out cleverer approaches
like 0 alpha or SkBlendMode::kDst.)
Instead, we accessTopLayerPixels() and slurp the subframe out into a
16-bit accumulator, then when all subframes have drawn and accumulated
there, one more saveLayer() and accessTopLayerPixels() lets us put them
back, shifting back down to 8-bit.
The hot parts of the profile are drawing the frames themselves, then the
accumulate / repack code in renderToRaster8888Pow2Samples().

* Added a new binding type, SkEffectBinding. This stores another
entire effect params structure (so the JSON is just nested).
The name is a callable value that spawns a new instance of
that effect, inheriting the parameters of the spawning effect
or particle (depending on which kind of script made the call).
* Broke up the monolithic update function into some helpers,
got some code reuse with the script calling logic.
* Unlike particle capacity, there is no upper limit on child
effects (yet), so it's easy to trigger runaway memory and
CPU consumption. Be careful.
* Added death scripts to effects and particles, which are a
common place to want to spawn sub-effects. Like spawn,
these run on each loop, but for one-shots they play at the
end. Even with loops, this is helpful for timing sub-effects
(see fireworks2.json).
* Finally, added a much more comprehensive example effect,
raincloud.json. This includes a total of three effects, to
generate a cloud, raindrops, and splashes when those drops
hit "the ground".

This change adds another layer of complexity and control to
the particle system. There are now two code chunks: the old
code that's run per-particle, and new code that's run for
the effect itself. This allows for effect lifetime to be set
by the script (eg, randomly), as well as the emission rate.
Rate can vary over time (see pulse.json), and particles can
be emitted in bursts by setting the effect's burst field
(see fireworks.json).
Additionally, the effect has its own frame of reference and
color, which becomes the default state for newly emitted
particles. This allows synchronizing state across particles
in various interesting ways (see color in fireworks.json).

We're currently letting render context overrides (opacity, color
filters, blend mode, etc) spill down the descendent/mask content
tree.
This is not ideal, as mask content isolation breaks atomicity
assumptions for deferred overrides. Case in point: motion blur uses
SkBlendMode::kPlus to accumulate content "layers" - but since mask
content gets rendered into a separate layer, it fails to produce the
expected result.
The fix is to realize all context overrides on the top-level mask layer
(we already allocate this layer, so there's no reason to defer
downstream anyway).

These unused comparison operators are the only users of
<functional> in SkRefCnt.h, for std::less. <functional>
is an expensive header to compile, and SkRefCnt.h is popular,
so it helps to cut dependencies like this.
Mostly we just need to add #include <functional> in a few
places that were picking it up via SkRefCnt.h.
In SkPixmapPriv.h, it looked simpler to template the argument,
since everything was inline anyway.

<ostream> is one of the more expensive headers to include
and that's amplified by SkRefCnt.h's popularity.
We've been including <ostream> for sk_sp's operator<<. That's only
used by Chromium and while we could just sprinkle in a bunch of .get()
calls and remove operator<<, when I started going through and actually
doing that I got the feeling I was making things pointlessly harder to
read and write, and wanted to find a way to make it actually work.
My next instinct was to template it without mentioning ostreams,
template <typename OS, typename T>
auto operator<<(OS& os, const sk_sp<T>& sp) -> decltype(os << sp.get()) {
return os << sp.get();
}
but that makes this operator<< ambiguous with some other templated operator<<
in GTest. They got in first, so they win...
So ultimately, switch <ostream> to <iosfwd>. Anyone using our
operator<<() presumably has <ostream> included already, and the #include
cost for <iosfwd> is small enough that I don't think we'll mind keeping
this around indefinitely.
To repro, look at before/after of -ftime-trace:
~/chromium/src/third_party/llvm-build/Release+Asserts/bin/clang++ -I. -Os -c src/core/SkCanvas.cpp -ftime-trace
I have tested locally that Chromium builds with this change.
