This allows for using non-contiguous input in a future api for shaper.
This change forces cleanup of error handling when doing low level
shaping, which prompts cleaning up the correct shaper code to make the
control flow more obvious.

Camera layers introduce a top-level 3d camera/view matrix based on their
transform properties:
* position - camera location
* point of interest (stored as anchor point by BM) - camera direction
* rotation - camera orientation
The perspective degree is controlled by a "zoom" camera property (which
corresponds to the view distance), and the composition dimensions.
Current limitations:
* single camera track/layer
* affects all layers (not just 3d-tagged layers)
* parent layer transforms are likely not applied correctly

AE supports two text layout modes [1]:
* point text: text is laid out on an infinite line, starting at the given position,
and observing explicit line breaks only; in this case the text baseline is at the
given position.
* paragraph (box) text: text is laid out within the given box, using line breaks to
fit.
This CL implements the latter mode, in addition to the already supported point mode:
- parse & plumb the text box info
- update the text adapter logic to use SkShaper's width-constrained shaping mode
- tangentially, fix sksg::TextBlob's bounds computation

- Having all of the params in a single struct allows us to move
the remaining animated behaviors into affectors (color/frame).
- Added SkColorCurve, which works like SkCurve for SkColor4f.
Use that to create a color affector (rather than simple
start/end colors in the effect params).
- Also put the stable random in SkParticleState. This is going
to be necessary if/when we change affectors to operate on all

Effects now have a duration, and can be played looped
or one-shot. Added a second list of affectors that are
applied at spawn vs. update.
Effects grab and store the SkRandom at construction,
so it no longer needs to be passed to update().

This supports arrays of any type, and removes all of the special case
code for arrays of SkReflected objects. (This is extracted from my

This adds a new "Particles" slide to viewer, that allows
editing, loading, and saving particle effects. All of the
particle system code is in modules/particles.
There are many rough edges and some not-yet-finished changes
to generalize the model[1]. A rough overview:
- SkReflected.h implements a lightweight reflection system
for classes derived from SkReflected. Adding a new class
involves deriving from SkReflected, adding a macro to the
class declaration, and implementing visitFields(), which
simply calls a virtual on an SkFieldVisitor for each field.
Currently, emitters and affectors use this mechanism.
- SkParticleSerialization.h demonstrates two useful field
visitors - for serializing to and from JSON. The driver
code that uses those is directly in ParticlesSlide.
- SkParticleData.h and SkCurve.h define a variety of helper
types for talking about particles, both for parameterizing
individual values, and communicating about the state of a
particle among the effect, affectors, and emitters.
- SkParticleEffect.h defines the static data definition of
an effect (SkParticleEffectParams), as well as a running
instance of an effect (SkParticleEffect). The effect has
simple update() and draw() methods.
- ParticlesSlide.cpp adds a third field visitor to generate
GUIs for interactively editing the running effect.

1: The critical change I'd like to make is to remove all
special case behavior over time and at spawn (setting sprite
frames, size over time, color over time, etc...). Integration
is the only fixed function behavior. Everything else is driven
by two lists of affectors. One is applied at spawn time, using
the effect's lifetime to evaluate curves. This allows spawning
particles with different colors as the effect ages out, for
example. The second list is applied every frame to update
existing particles, and is driven by the particle's lifetime.
This allows particles to change color after being spawned, for
example.
With a small set of affectors using a single expressive curve
primitive (keyframed list of cubic curve segments), we can
have affectors that update color, size, velocity, position,
sprite frame, etc., and implement many complex behaviors.

Introduce RenderNode::nodeAt(const SkPoint&) as the entry point for the hit-testing API.
This is backed by a onNodeAt() virtual, which gets dispatched throughout the render DAG,
and normally stops at the first leaf Draw node in encounters.
To support the implementation, introduce a GeometryNode::contains(const SkPoint&) API.
This is backed by a onContains() virtual, overridden in each concrete geometry class.
Expose nodeAt() on sksg::Scene, and add some basic unit tests.

Image filters cannot let descendent damage pass through, as they may
transform their inputs arbitrarily.
Introduce the notion of "damage override" SG nodes (nodes which block
descendent damage and replace it with their own), and update
ImageFilterEffect to opt in for this behavior.
Also make InvalidationController damage dispatch optional (such that we
don't accumulate inval rects unnecessarily).

There are currently two consistent ways to do line breaking. The 'ok'
way where the entire line is shaped and the resulting glyphs broken
into lines based on hopeful cluster breaks. This has the one nice
property of preserving all shaping done by the font. The 'correct' way
is to shape to each break opportunity and pick the best one, then
continue to do so for each line. This has the nice property of not
shaping incorrectly.
Fortunately, the actual implementation can be hidden behind a common
interface. Keep both of them to ensure this continues to be the case.

icu/BUILD.gn defines SK_USING_THIRD_PARTY_ICU if needed.
SkShaper_harfbuzz.cpp SkPDFSubsetFont.cpp respects
SK_USING_THIRD_PARTY_ICU when calling SkLoadICU().
sfntly/BUILD.gn, harfbuzz/BUILD.gn, icu/icu.gni uses $_src variable to
