3977088e23 Enable ClangTidy check readability-static-accessed-through-instance.
Our codebase generally tends to avoid this pattern naturally, and this
can catch real mistakes, e.g. http://review.skia.org/308659

a6841be235 Enable ClangTidy check llvm-namespace-comment.
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.

8155976877 [skottie] Add line-spacing animator support
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
    is the average of the computed spacing for each fragment
  - 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)

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.

0dc207f836 [skottie] Cleanup: refactor asset lookup to avoid std::function
The main value of current AnimationBuilder::attachAssetRef is to provide
scoping semantics for ref cycle detection.

Refactor using a RAII helper (ScopedAssetRef), and avoid std::function
callbacks.

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.

8b70f4d052 [skottie] Video layer support
Bodymovin exports video layers similar to image layers, but assigns a
dedicated type id.

Since Skottie's ImageAsset interface already supports multi-frame
images, we can reuse the same mechanism for video.

Also, since we're adding sparse layer type handlers, we can now
fill all known Lottie layer enums and simplify the handling of camera
layers.
