b77d502946 Particles: Cleanup and better UI
Remove SkAnimTimer from the module interface entirely.
Clean up some other SkParticleEffect methods. Simplify
VisitTypes to just visit all of them, it's easier for
the client to do any filtering.

In the slide, make the UI far nicer. Load all files in
a given directory, and allow editing (and saving) them
all at once, or adding a new entry. Support multiple
playing effects, with a draggable handle to set the
position.

bdcdf1a7c3 Add SkParticleValue to allow further customization of curve behavior
All curves (and path affectors) are driven by an SkParticleValue. The
value can derive its value from the current defaults (age of particle
or effect), or explicitly choose the other one, a random value, or any
other particle value. Values can be range adjusted and support repeat,
clamp, and mirror tiling.

Also fixed some more issues related to resource path in the slide GUI.

34d1331323 Particles: Improvements to SkCurve
Added explicit Linear segment type, merge math evaluation helpers for
scalar and color curves. Add logic to visitFields that cuts down on the
serialized size of simple curves, and makes the GUI easier to work with.

Remove the curve plot from the GUI. It was incorrect (wrong points at
cubic handle locations), not terribly helpful, and difficult to
maintain.

0c48681e58 Few more particle features and some generalization work
Add particle "frame" enum, to allow effects relative to local, world,
or velocity. Remove the "orient along velocity" and replace with a much
more general orientation affector (angle curve + frame). Add an angular
velocity affector to mirror the behavior of the linear velocity affector.

14a67a3a71 Change particle affector to work on N particles
This should severely cut down on the virtual call overhead when running
affectors. It also switches to model of "for each affector, do each
particle", rather than "for each particle, do each affector". This is
going to be an I$ improvement, and (if we ever care), make it possible
to do wide-mode threading of the affectors on disjoint blocks of
particles.

bd64f18947 [skottie] Layer blend mode support
Introduce sksg::BlendModeEffect and use to wrap Skottie layers based on
their "bm" property.

Depending on the presence of non-trivial layer blend modes and the nature
of the destination buffer (fully transparent vs. unknown/pre-filled), we
may now need to render animation frames into a separate layer for correct
compositing.

Track the presence of non-trivial layer blend modes such that we only incur
this extra layer overhead when needed.  Also allow clients to pass a "drawing
to fully transparent buffer" hint such that we can avoid the extra layer even
when blend modes are present.

125daa4d1a Refactor and further generalization of particle model
- Collapsed the per-particle data into a single struct, and
  use that to communicate with drawables, too. Let the drawables
  manage allocation of xforms, colors, etc. Helpful for non-atlas
  drawables, and just to keep the effect code simpler.
- 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
  particles (rather than one at a time). Still need to move t
  value into the particle struct (or eval it from the lifetime
  params on demand).

112aa2d22e Add curve visualization back, guard eval
Editing curves is still cumbersome, but that's fine.
Visualization is just for feedback (and imgui's path
renderer is a little wonky), but this helps a bit.

8b6283fc98 New SkCurve type with multiple curve segments
- Converted all linear force stuff into a single affector,
  used at either spawn or update time appropriately.
  The new affector can either set or adjust velocity.
- Converted lifetime to a curve.
- Removed SkRangedFloat, initial velocity params, etc.

Looks like a large addition, but that's mostly down to the
JSON getting bigger. There's a net reduction in LoC.

5c1f8eb094 Various particle system improvements
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

7c979f52c3 Experimental Particle System
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.
