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.

The other generator was never used (or useful). String-based serialization

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.

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).

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.

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.

f05626bf96 Test a GIF with an out of range transparent index
Bug: skia:8461

According to skbug.com/7069, we should allow GIFs to use a transparent
index outside of the range of the color table. Add a test to verify
support for this.

The GIF is 2x2 with the following pixels:
-------------------------------------------------
|   black            |          white           |
-------------------------------------------------
|   transparent      |      transparent         |
-------------------------------------------------

The color table only has 2 entries (black and white), and the
transparent index is 2.

81886e8f94 Switch SkCodec to use skcms
Bug: skia:6839
Bug: skia:8052

Create an skcms_Profile instead of an SkColorSpace when creating an
SkCodec. Eventually we'll move the SkImageInfo (and its SkColorSpace)
entirely to clients (e.g. SkAndroidCodec, SkCodecImageGenerator), but
for now, create it with SkEncodedInfo::makeImageInfo.

Create new SkEncodedInfo::Colors for the special PNG cases that we
want to map to specific SkColorTypes.

SkEncodedInfo:
- Add ICCProfile, which owns an skcms_ICCProfile
 - FIXME: maybe we should have a single instance for
  SRGB like SkColorSpace?
- Add kXAlpha_Color, for kAlpha_8. Since I'm not longer creating
  an SkImageInfo (at least in SkPngCodec), it needs a way to pass
  this info to the caller.
- Add k565_Color, for the same reason. Matt originally had this in
  https://codereview.chromium.org/2212563003/#ps120001, but didn't
  land that version. I like it though. Mike didn't like the bits
  per component for 565, but it seems like a sensible hack, much
  like the existing one for kAlpha_8
- Add width and height. These were removed for redundancy with
  SkImageInfo, but it makes sense to have them here without it.
BUILD.gn:
- Build the new SkEncodedInfo.cpp
SkCodec:
- Remove the constructor with an SkImageInfo. Edit the other one
  to drop width and height (now in SkEncodedInfo) and take a RHS
  reference to SkEncodedInfo
- Create the SkImageInfo from fEncodedInfo (for now)
- Consolidate choosing skcms_AlphaFormat for Transform here
- Call conversionSupported from initializeColorXform, with a new
  parameter for whether there is a color Xform, allowing SkJpegCodec
  and SkHeifCodec to override that method instead of having another
  method.
SkBmpCodec (etc)
- Adapt to the changes above
- Create a new SkEncodedInfo w/o profile for the swizzler.
SkPngCodec:
- use the new SkEncodedInfo::Colors rather than a custom SkImageInfo
SkRawCodec:
- Remove SkEncodedInfo from SkDngImage, which doesn't actually need it.
  This is helpful since we don't know all the info yet.
- Rewrite gAdobeRGB_toXYZD50 as an skcms_Matrix3x3
SkWebpCodec:
- Remove premul_step computation, and simplify to just rely on
  the base class' handling of applying the transform.
SkSwizzler:
- Add cases for the new SkEncodedInfo::Colors

TBR=reed@google.com
No public API changes. Only private/public members of SkCodec.h are
modified.

The upperLeft and upperRight profiles are A2B/B2A-only, and so cannot be
represented as SkColorSpace using SkColorSpace::Make(skcms_ICCProfile).
They do parse fine, of course.

03cd6e6dec Avoid serializing to 'typ1' on Mac.
CoreGraphics does not provide a means to get the original font data for a
CGFont, only the tables. As a result, Skia pieces the font data back
together when requested. The most awkward part of this is choosing the
first four bytes, and the CTFont suggestion seems to often be wrong.

This change doublechecks the selection of 'typ1', prefering to use 'OTTO'
if there are no 'TYP1' or 'CID ' tables. These sorts of fonts are
extremely old and unlikely to be in current use. It appears that CTFont
may report that it has this format if it is an 'OTTO' font with very few
glyphs. If Skia serializes such a font with 'typ1' as the first four
bytes, CoreGraphics will not create a CGFont from the resulting font data.

Bug: oss-fuzz:6274

Even if a frame does not have enough LZW blocks to decode all rows,
(which is unknown until we actually decode them), it is marked complete
once there are no more LZW blocks.

When decoding, even if we've decoded all LZW blocks, check fRowsDecoded
to determine whether we've actually all the rows. Report the number of
rows decoded so that SkCodec can fill in the remaining ones.

da3e9ad894 Make SkAndroidCodec (optionally) respect origin
Bug: b/63909536

ImageDecoder will respect the origin, but BitmapFactory will maintain
its current behavior of not respecting it. Add an option to respect it.

In addition, add support for reading the EXIF data from a WEBP. This
seems to be an uncommon use case, but is occasionally used when
converting from a JPEG. Add 8 WEBPs, all converted (with cwebp) from
their analogous JPEG files already checked in.

094ccde238 Initial Lottie loader impl (Skotty)
Coarse workflow:

* Construction

  1) build a Json tree
  2) collect asset IDs (for preComp/image layer resolution)
  3) "attach" pass
     - traverse the Json tree
     - build an SkSG dom, one fragment at a time
     - attach "animator" objects to the dom, for each animated prop
  4) done, we can throw away the Json tree

* For each animation tick

  1) iterate over active animators and poke their respective dom nodes/attributes
  2) revalidate the SkSG dom
  3) draw the SkSG dom

Note: post construction, things are super-simple - we just poke SkSG DOM attributes
with interpolated values, and everything else is handled by SkSG (invalidation,
revalidation, render).

a12f795f4a Fix Adobe RGB color space in Skia
Our runtime definition of the XYZ matrix was fairly inaccurate. It also
didn't round-trip through ICC fixed point correctly. Now, constructing the
color space at runtime produces exactly the same matrix as constructing
the space from the ICC profile. And the values can then be serialized back
to ICC exactly. This eliminates the need for the snapping logic, too.
