22ea7e994b add Builder::dump()
I used to have a dump of the value program before it was
translated to registers, but it went away a while ago.
This restores it.

a630732c36 revise extract instruction
Convert extract(x,bits,z) to be (x >> bits) & z,
now a more explicit parallel to pack().

This lets us eliminate the funky bit counting required from the old
instruction, but more saliently it makes it more likely that the masks
we AND with will be the same value.

Ultimately down at the x86 or ARM ISA level, the AND instructions don't
really benefit from having an immediate argument (while the shifts do).
We might as well treat the mask as a normal value, letting it get
commoned with identical values, loop hoisted, etc.

54c8411c27 [skottie] Fix zero-overlap selector handling
The current implementation applies constant coverage (outside selector
range) based on computed integral edges.

But the integral range is clamped to the valid index domain and its
extremes are always assumed to have partial coverage - so we never get
to constant-blit the full buffer when the interval is outside, which
can yield incorrect coverage for the first/last fragments.

Update the constant coverage logic to operate in full domain coordinates.

6b43c30cd7 add mad_unorm8 instruction
At some point adding more and more complex instructions reduces
to the absurdity of SolveTheWholeProblem-The-Instruction, but
I think this one will come up often enough to still make sense.
mad() makes sense for unorm8 just about everywhere mad() makes
sense for f32.

This instruction won't matter to a JIT, but helps the interpreter.

754bad3f38 hoist loop-invariant code out of the loop
I'm of two minds about this... it adds register pressure and really only
tends to hoist few instructions that are fairly cheap anway.  On the
other hand, it's neat, it's easy to turn off (just set the initial
hoist value to false in Builder::push()) and it does deliver a
noticeable though slight performance improvement in the interpreter.

I think the final decision will probably come down to what we think
about maintainability?

1c44db15d1 [skottie] Initial text range selector support
Each animator can have multiple range selectors, whose combined "coverage"
modulates how the animator props compose with other/initial props.

Since there can be multiple animators with different/arbitrary selectors,
we compute independent property values for each fragment.

Supported features:

 - start, end, offset, amount
 - units: percentage, index
 - based-on: characters-only for now
 - mode: add-only for now
 - shape: square-only for now

1d89b0d7e1 [skottie] Add support for scale and rotation text animators
The interesting bit here is a change in glyph positioning:
AE text animator transforms are to be applied relative to the glyph position.

To support this behavior, update Shaper to externalize glyph positioning
when in fragmented mode.  I.e. instead of baking glyph positions in blobs,
apply them at the scene graph transform level (such that they compose with
animated transforms correctly).

201700fa86 Initial version of rescaling async readback API
This is implemented at backend-neutral level and so misses some
opportunities to reduce the number of passes in the GPU backend.

Filter quality is interpreted as:
none - single nearest neighbor resampling
low - chain of bilinear resamplings. 2x up/down except for one
step which may be smaller than 2x.
medium - same as low
high - when both scale factors are up then same as low but with bicubic
filtering rather than linear. Otherwise, same as low.

83c2f70b51 Compile all fiddle examples locally
Motivation: it would be a good idea if the API documentation examples
were checked into the skia repository, so we could make sure they
compile as part of the commit queue.

Fiddle would make/update a named fiddle each time it gets a new
commit of Skia, extracted from the code in the examples/ directory.
The docs would point at those named fiddles.  Named fiddles have urls
in the form:

    https://fiddle.skia.org/c/@Bitmap_000

Then we would stick a link to the example into the header documentation
like this:

    /** Allocates the pixel memory for the bitmap, given its dimensions
        and SkColorType. Returns true on success, where success means
        either setPixels() or setPixelRef() was called.

        @param bitmap  SkBitmap containing SkImageInfo as input, and
                       SkPixelRef as output
        @return        true if SkPixelRef was allocated

        @example       https://fiddle.skia.org/c/@Bitmap_000
    */
    bool allocPixelRef(SkBitmap* bitmap) override;

There are still around 200 disabled examples that need to be fixed
(these result from API changes since the author left).

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

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.

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.

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.

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.

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.

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.

33deb7ed4d Make SkCodec more flexible about its required frame
SkCodec sets fRequiredFrame to be the earliest possible frame that a
given frame can depend on. e.g.

- Frame A fills the screen, Keep
- Frame B does not cover A, Keep
- Frame C covers B but not A, and is opaque

Frame C can depend on either A or B. SkCodec already reports that C
depends on A. This CL allows a client of SkCodec to use either A or
B to create C.

Also expose the DisposalMethod. Since any frame between A and C can
be used to create C except for DisposePrevious frames, the client
needs to be able to know the disposal method so they do not try to
use such a frame to create C.

Further, the disposal method can be used to give the client a better
idea whether they will continue to need a frame. (e.g. if frame i is
DisposePrevious and depends on i-1, the client may not want to steal
i-1 to create i, since i+1 may also depend on i-1.)

557fbbe05b Add animation support to SkWebpCodec
TBR=reed@google.com
(No change to the public API, but changed a header file)

SkWebpCodec:
- Implement onGetFrameCount, onGetFrameInfo, and onGetRepetitionCount
- Respect the alpha reported by libwebp. Although the spec states that
  it is only a hint, the libwebp encoder uses it properly. Respecting
  allows us to draw opaque images faster and decode them to 565. This
  also matches other SkCodecs (and Chromium).
- onGetPixels:
  - Decode the frame requested, recursively decoding required frame if
    necessary
  - When blending with a prior frame, use SkRasterPipeline

SkCodec:
- Move check for negative index to getFrameInfo
- Reset the colorXform if one is not needed

SkCodecAnimation:
- Add new blend enum, for WebP's (and APNG's) non-blending option

SkFrameHolder:
- New base classes for frames and the owner of the frames, allowing
  code sharing between SkWebpCodec and SkGifCodec (particularly for
  determining whether a frame has alpha and what frame it depends on)
- When moving items from SkGIFFrameContext, use Skia conventions (i.e.
  int instead of unsigned)
- Rename "delay time" to "duration", to match e.g. SkFrameInfo::
  fDuration

SkGifImageReader:
- Move pieces to SkFrameHolder, and adapt to changes made in the
  process
- Make setAlphaAndRequiredFrame (now on the base class SkFrameHolder)
  more general to support webp, and add support for frames that do not
  blend
- Change SkGIFFrameContext from a struct to a class, to match how we
  use the distinction elsewhere (i.e. struct is a small object with
  public fields)
- Rework hasTransparentPixel (now hasTransparency, since it returns true
  in some cases where there is not a transparent pixel) to better fit
  with the modified setAlphaAndRequiredFrame. Also be more consistent
  when there is no transparent pixel but no color map.
- Simplify an if condition that was previously simplified in 2d61e717
  but accidentally got reverted in a4db9be6

CodecAnimTest:
- Test new animated webp files
- Rearrange the test to more cleanly print alpha type mismatches for
  the first frame

resources:
- webp-animated.webp
  - animated webp from Chromium
- blendBG.webp
  - new webp file using bits of webp-animated-semitransparent4.webp
    from Chromium
  - tests required frame and alpha when using the non-blending mode
  - frames have the following properties:
    - Frame 0: no alpha, fills screen
    - Frame 1: alpha, fills screen
    - Frame 2: no alpha, fills screen
    - Frame 3: alpha, fills screen, blendBG
    - Frame 4: no alpha, fills screen, blendBG
    - Frame 5: alpha, blendBG
    - Frame 6: covers 4, has alpha, blendBG
  - also used to test decoding to 565 if the new frame data has alpha
    but blends onto an opaque frame

DM.cpp:
- Test animated images to non-native 8888 and unpremul

DMSrcSink.cpp:
- Do not test non-native 8888 decodes to f16 dst
- Test unpremul decodes to f16
- Copy a frame of an animated image prior to drawing, since in unpremul
  mode, the DM code will premultiply first.

2e61b182da Add jpeg encoder alpha handling option
This instructs us on how to encode jpegs when the src
image has alpha.  The original behavior is to ignore
the alpha channel.  This CL adds the option to blend
the pixels onto opaque black.

Note that kBlendOnBlack and kIgnore are identical
unless the input alpha type is kUnpremul.

In this case, the fuzzer thinks there is a bug because we are
returning kInvalidConversion for a corrupt png file.

7d22a33e21 Add a test for getFrameInfo on truncated data
Prior to e132e7be5f, calling getFrameInfo
on an SkGifCodec which was truncated before fully parsing the local
color map of the first frame would hit an assert. Add a test to verify
that the problem has been fixed.

Modify box.gif to use a local color map for the first (and only) frame.

a4db9be6a2 Correct GIF frame dependencies and track alpha
Add SkCodec::FrameInfo::fAlphaType. The SkImageInfo for the SkCodec
specifies the SkAlphaType for the first frame, but the opacity can vary
from frame to frame.

When determining the required frame, also compute whether a frame has
alpha. Update how we determine the required frame, which had bugs.
(Update a test that had an incorrect required frame as a result.)

Add new test images covering cases that have been fixed:
- randPixelsAnim2.gif
It has the following frames:
A (keep)
B (keep) (subset)
C (disposePrevious) (covers B)
D (any) (does *not* cover B)

B and C depend on A, but D depends on B, since after disposing C, B
should be visible again.

- alphabetAnim.gif
Includes frames which fill the image size, with different disposal
methods and transparencies.
