The client can do a test run of their application with
a persistent cache set to SkSL mode. They store the key
and data blobs that are produced.
Ship those blobs with the application. At startup, call
GrContext::precompileShader for each key/data pair. This
compiles the shaders, and stores the GL program ID, plus
a small amount of metadata in our runtime program cache.
Caveats:
* Currently only implemented for the GL backend. Other
backends will require more metadata to do any useful
amount of work. Metal may need a more drastic workflow
change, involving offline compilation of the shaders.
* Currently only implemented for cached SkSL (not GLSL
or program binaries). Supporting other formats again
requires more metadata, and the cached shaders become
increasingly specialized to GPU and driver versions.
* Reusing the cached SkSL on different hardware is not
supported. Many driver workarounds are implemented in
the SkSL -> GLSL transformation, but some are higher
level. Limiting device variance by artificially hiding
extensions may help, but there are no guarantees.
* The 'gltestprecompile' DM config exercises this code
similarly to 'gltestpersistentcache', ensuring that
results are visually identical when precompiling, and
that no cache misses occur after precompiling.

Skia has traditionally snapped horizontal and vertical baslines to
pixels as a kind of baseline hinting. This is a feature which cannot
reliably be implemented from the outside and tends to make static text
better looking by ensuring the baselines are consistent. However, with
animation like scrolling or flying and resizing text the animation
suffers. Allow the user to disable the baseline snapping.

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.

There are now three modes: Legacy, and Color Managed 8888 or F16. Rules
about transfer functions are gone, so allow changing gamma in either
color managed mode.
To keep things much simpler, we always construct the window surface in
legacy mode, and draw offscreen whenever we're doing any color
management. This lets us avoid re-creating the window surface when
cycling modes, and avoid making re-tagged copies when pushing color
managed images to the window surface.

It's been driving me nuts that I can't just write `SkMatrix44 m;`,
and I often don't care whether it's initialized or not. The default
identity constructor would be nice to use, but it's deprecated.
By tagging this constructor deprecated, we're only hurting ourselves;
our big clients disable warnings about deprecated routines and use it
freely.
A quick tally in Skia shows we mostly use the uninitialized constructor,
but sometimes the identity constructor, and there is a spread of all
three in Chromium. So I've left the two explicit calls available.
I switched a bunch of calls in Skia to use the less verbose constructor
where it was clear that it didn't matter if the matrix was initialized.
Literally zero of the kUninitialized constructor calls looked important
for performance, so the only place I've kept is its lone unit test.
A few places read clearer with an explicit "identity" to read.

After the last update to ImGui, windows delayed visibility for one
frame, to get properly sized. We would detect that no windows were
"active" (really, visible) and not re-paint, so we never got the second
frame when the window finally showed up.
Omar put a fix to the stats in ImGui for this, so that Active windows
are tracked separately from Visible. This pulls that change in, and
updates the test to correctly redraw when the GUI requires it.
