41248071ac tools: separate TimeUtils from AnimTimer
gm, slides, and samples no longer need to know about the implementation
details of AnimTimer.

This
    virtual bool onAnimate(const AnimTimer&);
becomes this:
    virtual bool onAnimate(double /*nanoseconds*/);
which is much easier to reason about.

AnimTimer itself is now part of viewer.

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

No-Presubmit: true

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.

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().

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.
