c1c3c6d70d Enable ClangTidy flag bugprone-suspicious-string-compare.
https://clang.llvm.org/extra/clang-tidy/checks/bugprone-suspicious-string-compare.html

Find suspicious usage of runtime string comparison functions.
This check is valid in C and C++.

Checks for calls with implicit comparator and proposed to
explicitly add it:

  if (strcmp(...))       // Implicitly compare to zero
  if (!strcmp(...))      // Won't warn
  if (strcmp(...) != 0)  // Won't warn

Checks that compare function results (i,e, strcmp) are compared to valid
constant. The resulting value is

  <  0    when lower than,
  >  0    when greater than,
  == 0    when equals.

A common mistake is to compare the result to 1 or -1:

  if (strcmp(...) == -1)  // Incorrect usage of the returned value.

Additionally, the check warns if the results value is implicitly cast
to a suspicious non-integer type. It’s happening when the returned
value is used in a wrong context:

  if (strcmp(...) < 0.)  // Incorrect usage of the returned value.

1cf2c8d6ec Enable ClangTidy flag modernize-use-override.
https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-override.html

Adds override (introduced in C++11) to overridden virtual functions and
removes virtual from those functions as it is not required.

virtual on non base class implementations was used to help indicate to
the user that a function was virtual. C++ compilers did not use the
presence of this to signify an overridden function.

7806794543 [skottie] Initial audio layer plumbing
Looking at audio layer support for Skottie, we need an API to
externalize audio asset loading and playback.

Similar approach to the other resource types for loading, but in
addition we also delegate playback control to the embedder.

First thought: keep it really simple and just emit seek() events.
Positive |t|s for track playback, negative for track off.

The embedder needs to implement state menagement (playing/not-playing)
and optional synchronization (if animation playback is not real time).

This fixes a large number of SkSL namespaces which were labeled as if
they were anonymous, and also a handful of other mislabeled namespaces.
Missing namespace-end comments have been added throughout.
A number of diffs are just indentation-related (adjusting 1- or 3-
space indents to 2-space).

fbd050bd0b Enable ClangTidy check modernize-make-unique.
The majority of existing call sites were automatically updated using
clang-tidy -fix. A small handful required a manual update,
e.g. CppCodeGen.

This check is a bit lenient, and in particular will not flag cases like
`std::unique_ptr<Base>(new Derived())` which is still pretty common
throughout our codebase. This CL does not attempt to replace all the
cases that ClangTidy does not flag.

a524ea266d [skottie] More masking fixes
Assorted bugfixes for the non-analytical mask code path.

1) SkSG modulatePaint() should only override the blend mode when
   one is specified (!= kSrcOver).

2) Some modes (notably intersect) require touching pixels outside the
   mask draw geometry.  These modes must be applied as a layer.
   Introduce an explicit layer node in SkSG, and inject for masks which
   require it.

Also refactor Subtract to use more natural blend and pathops modes,
instead of always inverting geometry.

cd11a51a11 [skottie] Fix mask difference
Difference [1]:

  The mask is added to the masks above it in the stacking order. In
  areas where the mask does not overlap the masks above it, the mask
  operates as it would alone on the layer. In areas where the mask
  overlaps the masks above it, the influence of the mask is subtracted
  from the masks above it.

^ sure sounds like XOR

cfbb56c6e1 [skottie] Auto-orient fixes
Two issues:

1) For static keyframes (start_value == end_value) AE yields horizontal
   orientation (0 tangent).  We technically have the same logic in
   Skottie, but our value deduplication logic interferes: the two
   consecutive equal values are consolidated, and the result ends up
   holding the spatial lerp info for the next frame => our hold frames
   auto-orient for the beginning of the next keyframe.

   Fix: skip value deduplication when spatial lerp is present.

2) The very last keyframe is always static and holds no spatial info.
   AE retains the orientation of the previous frame, but Skottie yields
   0 tangent.

   Fix: the easiest way to accomplish AE semantics is to detect when
   we're dealing with the last keyframe, and swap with the previous
   keyframe with an adjust weight of 1 (to select the end value).  This
   produces the same lerp result (because keyframed values are always
   contiguous) and also respects the orientation of the prev frame.

AE allows animating the line spacing text property [1].

Observed semantics:

  - spacing is applied as an offset to all fragments in a line
  - for selector/partial coverage, the spacing for a given line

  - spacing is cumulative (applies to all lines following)

Plumb the new animator prop ("ls") and expand the existing line
tracking logic to also apply computed spacing offsets.

(also requires a Bodymovin update to export the line spacing property)

6a414b277b [skottie] Layer auto-orient support
AE layers can be tagged for auto-orient - i.e. they observe an
additional rotation component dependent on the position property
animation (position derivative/tangent).

Augment Vec2KeyframeAnimator to optionally track orientation, for both
temporal/linear and spatial (motion-path) keyframes.  Update
TransformAdapter2D to use this orientation when attached to layer
transforms.

67ff541ac1 [skottie] Add support for embedded fonts (glyph paths)
Parse embedded fonts into SkCustomTypefaces, and pass down the text
animation pipeline.  Things seem to mostly work for Latin examples.

Most existing Lottie files come with embedded fonts (the option is
enabled by default), so to minimize disruption only use the new
feature as a fallback for typefaces which cannot be resolved otherwise.

Also introduce a builder flag to prioritize embedded fonts over native
(kPreferEmbeddedFonts), and plumb in existing tools for testing.

fbddfbb9f3 [skottie] Introduce an external layer API
Add support for external precomp Skottie layers.  This allows embedders
to seamlessly mix custom/Lottie content.

General flow:

  * embedders register a PrecompInterceptor callback with
    the animation builder
  * at build time, Skottie invokes the callback for each pre-composed
    layer
    - the returned ExternalLayer implementation is used instead of the
      Lottie layer payload
    - (a nullptr value signals Skottie to use the usual Lottie payload)
  * at render time, ExternalLayer::render() is called to defer content
    rendering to the embedder

Also implement a sample PrecompInterceptor which attempts to substitute
precmp layers matching a given pattern with external Lottie animations:

   precomp_name: "__foo.json"  -> Animation("foo.json")

This new mechanism is a generalization of (and supersedes) the old
NestedAnimation hack - so we can remove that.

eeaabc4ba2 [skottie] Vector-encoded paths
Lottie shapes (paths) are expressed as a sequence of vertices, where
each vertex has a

  - position
  - in-tangent control point (relative to position)
  - out-tangent control point (relative to position)

A nice property of this representation, is that interpolation can be
performed independently on each scalar component.

This seems really close to what VectorAnimator is good at - so can we
shoe-horn shapes into vectors and drop the ShapeValue KeyframeAnimator
specialization?  Yes, we can!

To support the conversion, we need to abstract out two aspects of the
VectorKeyframeAnimator builder:

  - parsing the encoding length of a vector-representable object
  - parsing the actual encoding data of a vector-representable object

(For current/regular vector values, the encoding length is the same as
the json array length, and the encoding data is just the array of json
numbers.)

Shapes are encoded as a sequence of 6 floats per vertex, plus an
additional/trailing boolean maker for the "closed shape" property:

 [v0.posX, v0.posY, v0.inX, v0.inY, v0.outX, v0.outY, ..., closed_flag ]

(thus encoding_len == 6 * vertex_count + 1)

After we're done with parsing, animation/interpolation is handled
via existing VectorKeyframeAnimator - so we can remove
KeyframeAnimator<ShapeValue>.

Converting to SkPath is pretty much the same as for the previous
representation, except the input is now flattened.

e990fcc4b0 Enable deprecated-copy-dtor warning.
In C++11 a user declared destructor still requires the compiler to
implicitly default the copy constructor and copy assignment operator,
but this is deprecated. Note that a user declared destructor suppresses
the move constructor and move assignment operator; a user declared
destructor exists if any '~Foo' method declaration appears inside
'class Foo' (even if defaulted); if the copy and move operations are the
same then copy operations that take 'const Foo&' will do fine double
duty as move operations.

Clang seems to have an issue with this warning, in that it does not
appear to distinguish between compiler defaulted and user defaulted
destructors. As a result, it does not always warn when it should.
There may yet be places in the code where a move operation is desired
but may be suppressed because the implicitly defaulted  moves are not
declared because a destructor has been declared.

This wraps dawn and shaderc configs in 'third_party' so that their
headers will be included through '-isystem' in order to avoid the
warnings generated by including their headers.

0147de41c4 [skottie] Lazy adapter sync
Expand the core animator logic to return whether the computed value is
changing on each tick.  Also rename tick/onTick -> seek/onSeek to better
reflect Skottie semantics.

This information allows us to skip adapter updates for static/hold
animation segments.

This effectively hoists some of the scene graph lazy-update logic to the
Skottie model level, and culls unneeded conversions (e.g. we were
converting ShapeValue -> SkPath on every tick, even when the shape was
not changing).

small-size vectors (3d values, colors).

Introduce a more efficient VectorKeyframeAnimator:

  - stores vector values in a contiguous/consolidated float array
  - keyframes reference value offsets in storage
  - fast/sk4f lerp impl

92ec801a2b [skottie] 2D spatial interpolation support
AE discriminates [1] between basic 2-dimensional properties
(PropertyValueType.TwoD - e.g. scale), and spatial 2D properties
(PropertyValueType.TwoD_SPATIAL - e.g. position).

For the latter it provides additional keyframe controls (tangent in &
tangent out) to describe a non-linear interpolation path ("spatial
interpolation").  This composes on top of the usual temporal
interpolation (with its own optional cubic mapping).

To support spatial interpolation:

  - introduce a new Skottie value type (Vec2Value), to represent
    TwoD and TwoD_SPATIAL properties
  - introduce a KeyframeAnimator specialization for Vec2Value, which
    tracks per-keyframe tangent information
  - for spatial keyframes, instantiate/store an SkContourMeasure, and
    use instead of straight Vec2 LERP
  - switch interesting 2D properties to the new value type (transform
    position, anchor point, scale)

(we could look into separating TwoD/TwoD_SPATIAL if needed, but the new
specialization is already more efficient than the old
opaque-vector-with-late-binding approach)

    - for atomic draws, apply the shader to the draw paint as

    - for isolated content, apply the mask as an extra pass
      drawPaint(kDstIn, mask_shader) before restoring the layer
  - refactor VenetianBlindsEffect, LinearWipeEffect and RadialWipeEffect
    to use mask shaders
  - additionally, refactor the RadialWipeEffect gradient to avoid using
    a local shader matrix (does not compose correctly within the new
    framework)

Everyone clear... do not touch the patient... BZZZT!

a9609ea8c5 turn on -Wreturn-std-move-in-c++11
This CL has a complicated back story, but it's concrete change is
simple, just turning the warning on and converting a bunch of

    return foo;

to

    return std::move(foo);

These changes are exclusively in places where RVO and NRVO do not apply,
so it should not conflict with warnings like -Wpessimizing-move.

Since C++11, when you return a named local and its type doesn't match
the declared return type exactly, there's an implicit std::move()
wrapped around the value (what I'm making explicit here) so the move
constructor gets an opportunity to take precedence over the copy
constructor.  You can read about this implicit move here under the
section "automatic move from local variables and parameters":
https://en.cppreference.com/w/cpp/language/return#Notes.

This situation comes up for us with smart pointers: a function declares
its return type as std::unique_ptr<Base> or sk_sp<Base>, and we return a
std::unique_ptr<Impl> or sk_sp<Impl>.  Those types don't match exactly,
so RVO and NRVO don't come into play.  They've always been going through
move constructors, and that's not changed here, just made explicit.

There was apparently once a bug in the C++11 standard and compilers
implementing that which made these copy instead of move, and then this
sort of code would do a little unnecessary ref/unref dance for sk_sp,
and would entirely fail to compile for uncopyable std::unique_ptr.
These explicit moves ostensibly will make our code more compatible with
those older compilers.

That compatibility alone is, I think, a terrible reason to land this CL.
Like, actively bad.  But... to balance that out, I think the explicit
std::move()s here actually help remind us that RVO/NRVO are not in play,
and remind us we're going to call the move constructor.  So that C++11
standard bug becomes kind of useful for us, in that Clang added this
warning to catch it, and its fix improves readability.

So really read this all as, "warn about implicit std::move() on return".
In the end I think it's just about readability.  I don't really hold any
hope out that we'll become compatible with those older compilers.

2e941d00c8 [skottie] Store scalar keyframe values inline
Generally, keyframe values live in dedicated storage, and are tracked in
keyframes based on their index.

This separation is not necessary for float values, as their storage size
is the same as their index's:

  - update keyframes to store value records (VRecs), which can hold
    either external value indices or inline floats

  - introduce a scalar animator specialization which operates on float
    VRecs and doesn't require dedicated value storage

b24f3b150c [skottie] Refactor keyframe encoding
For each Lottie keyframe, we currently store interpolation
*segments*:

 {
   t0, v0
   t1, v1
   cubic_mapper
 }

This is quite redundant:

 - kf(n).t1 == kf(n+1).t0 for all keyframes
 - kf(n).v1 == kf(n+1).v0 for all non-constant keyframes

Refactor to store single keyframe records:

  {
    t, v
    mapping
  }

To identify constant keyframes, since we no longer store
explicit hard stops, we now tag each record with a "mapping"
selector:

    0 -> constant keyframe
    1 -> linear keyframe
  > 1 -> cubic keyframe (adjusted cubic mapper index)


This reduces the storage size by 2/5, and yields overall cleaner
logic (as we're no longer back-filling info as we parse).

Also add a handful of unit tests to lock down limit semantics
(keyframe segments are left-inclusive/right-exclusive).

788b91678f Remove SkTMin and SkTMax
Use std::min and std::max everywhere.

SkTPin still exists. We can't use std::clamp yet, and even when
we can, it has undefined behavior with NaN. SkTPin is written
to ensure that we return a value in the [lo, hi] range.

ad9110026b [skottie] Separate text resize options
The sk_vj text property (Skottie extension) is currently mixing
vertical alignment and resizing semantics into a single enum.  This
precludes certain valid combinations.

Split the resize options into a separate enum (ResizePolicy), and ensure
support for all combinations.

Before:

  "sk_vj": 0 -> Shaper::VAlign::kVisualTop
  "sk_vj": 1 -> Shaper::VAlign::kVisualCenter
  "sk_vj": 2 -> Shaper::VAlign::kVisualBottom
  "sk_vj": 3 -> Shaper::VAlign::kVisualResizeToFit
  "sk_vj": 4 -> Shaper::VAlign::kVisualDownscaleToFit


After:

  "sk_vj": 0 -> Shaper::VAlign::kVisualTop
  "sk_vj": 1 -> Shaper::VAlign::kVisualCenter
  "sk_vj": 2 -> Shaper::VAlign::kVisualBottom

  "sk_rs": 0 -> Shaper::ResizePolicy::kNone
  "sk_rs": 1 -> Shaper::ResizePolicy::kScaleToFit
  "sk_rs": 2 -> Shaper::ResizePolicy::kDownscaleToFit

d5c42c8c03 [skottie] Refactor property animators
Currently, property animators use lambda captures (std::function<>) to push
values to adapters and then to the scene graph.  Some downsides:

  * complex lambda captures are expensive in terms of object code size
  * adapters with multiple animated properties don't synchronize/quiesce: each individual property tick triggers a SG
    synchronization, possibly with inconsistent state (as animator running
    order is unspecified)
  * there is no enforced scoping, resulting in fragile constructs when SG
    fragments are discarded

This CL introduces a simplified and more robust animator pattern:

  * property animators are scoped to explicit containers
  * instead of capturing arbitrary value functors, animators only capture
    a pointer to the target value

Some implementation details:

  * keyframe/interpolation logic is pretty much unchanged (just relocated)
  * introduced AnimatablePropertyContainer - a base class for animatable
    adapters
  * legacy binding functions are refactored based on the new mechanism
    (they now/transitionally inject adapter objects)
  * converted a handful of effects, to exercise trivial refactoring patterns
  * converted the text animator goo, to exercise non-trivial refactoring:
    - detecting value changes is now trickier (no more lambda magic)
    - value adjustments must be hoisted into adapter logic (no more lambda magic)
    - all dependent animated values (selectors, etc) must be scoped to the
      text adapter to avoid lifetime issues

ef363a9ce6 [skottie] Simplify effect builder lookup
Layer effects fall into two categories:

  - effects that BM knows about: these get assigned a unique type enum
  - effects that BM doesn't know about: these are still exported, but
    get assigned a dummy type

To handle effects in the latter case, we rely on their canonical AE
name.

The list of supported effects has grown to the point where a) this
differentiation doesn't seem valuable anymore and b) the code is quite
repetitive.

Consoliate the lookup logic to rely solely on effect names + bsearch
table.

46a331b93f [skottie] Cascading track matte support
Currently, we treat track matte source layers (tagged with td:1) as single-shot mask triggers:
we apply once to the following layer, then move on.

But track mattes can cascade: a layer with a matte can itself be applied as a track matte for the
following layer.

Also, for matte/masking purposes, only the layer content is being considered (ignoring blend mode
and any masks applied to the matte itself).

To support this, refactor the layer attachment code:

  - instead of tracking the presence of a single-shot matte source, always track
    previous layer content trees
  - instead of triggering matte attachment in the presence of a matte source, trigger based on
    the matte *target* property (tt: X)
  - log errors on unknown matte modes

870374825b [skottie] Explicit seek(0) in tools
With recent deferred image loading changes, Skottie relies on clients
to always/explicitly seek() before drawing a frame.

Some of the existing tools are still attempt to draw before the first
seek() fires (the animation callback is not guaranteed to occur before
the first draw).  For these, add an explicit seek(0) after loading the
animation, to ensure valid state.

cc92b27c78 [skottie] Optionally-deferred single-frame image loading
Normally, we load single-frame images upfront to avoid instantiating
an animator (as the image content is supposed to be constant).

In certain cases, deferred behavior is desirable (and the extra animator
overhead is minimal).

Generalize MultiFrameAnimator to handle single-frame assets, and add an
optional deferred mode for single-frame image loading
(Animation::Builder::Flags::kDeferImageLoading).

Having it means you cannot write:

SkSize size;
float x, y;
size = {x , y};

clang allows it but GCC does not, claiming it is ambiguous between the
implicitly generated
SkSize& SkSize::operator=(const SkSize&)
  and
SkSize& SkSize::operator=(const SkISize&)

clang gives the same error if the former is explicitly declared default.

75368c3a02 [skottie] Deferred image frame resolution
Instead of always grabbing the first frame at load time, only do so for
single-frame images.

For multi-frame images, defer frame resolution until actually needed
(at seek time).

There's a slight complication in dealing with image scaling: since we
no longer know the intrinsic size of the frames upfront, we need to
set up a transform effect preemptively for multi-frame images, and
update on the fly when the frames are resolved.  This is not
necessarily bad, because theoretically frames could have different
sizes.

85bf9314c0 Extracted Skottie's resource provider to a separate module
This is a first pass that should help with migrating clients.
The utility implementations of ResourceProvider are still in
skottie - those are going to be harder to move. More likely
that I'll add parallel implementations in skresources, then
we can shift clients over and delete the skottie copy.

I'm planning to use this interface/system in particles.

c6fbedc507 [skottie] 3D layer parenting refinements
Observed AE layer parenting semantics:

  * layers are flagged as either 2D or 3D
  * camera applies to 3D layers, but not to 2D layers
  * parented 3D layers treat their ancestor transform chain as 3D (SkMatrix44)
  * parented 2D layers treat their ancestor transform chain as 2D (SkMatrix, ignoring 3D components)

This means that for a given layer, we may need to build two distinct transform chains - depending
on the type of descendant layer being considered.

Furthermore, transforms are animatable and their animators are scoped to a layer controller.  Since
we're potentially building two version of the transform node, we need to ensure all animators for
both of them are transferred to controller object (we still want to only instantiate a single layer
controller and render tree to avoid duplication).  IOW, all dependent layer transforms need to be
considered before "sealing off" a given layer controller.

In order to avoid a layer dependency/topological sort, we can split off the transform tree
construction into a separate pass.  High-level changes:

  -- replace existing LayerAttachContext with CompositionBuilder
     (holds LayerBuilders and other Composition-wide state)

  -- replace LayerRec with LayerBuilder
     (holds Layer-wide state and also caches transform nodes)

  -- pass 1: for each LayerBuilder, transitively build and cache a transform chain
     of a type (2d/3d) determined by the leaf (entry point) layer

  -- pass 2: for each LayerBuilder, build the actual layer content render tree
     and instantiate the layer controller objects
