18cb4a67d8 [skottie] Fix MotionTile/opacity interaction
Some group effects (including layer opacity) are not applied upfront,
via an expensive saveLayer, but are deferred until we can determine
whether they can be folded into an atomic draw's paint (to avoid the
extra layer).

At the moment, the MotionTile custom render node drops all pending
paint effects on the floor (ignores |ctx|).  Update to apply via the
shader paint.

Also update a couple of related tests to animate opacity.

6ba939d288 [skottie] Improved Hue/Saturation effect
The current HueSaturation effect implementation relies on a simple
HSLA color matrix operation and assumes the controls are linear.

Turns out AE's saturation is more sophisticated, both in implementation
and in control mapping.

Updating the effect to use a chain of specialized color filters:

  - keep HSLAMatrix() for hue adjustments
  - introduce a custom runtime effect for saturation
    (following AE's semantics)
  - use a plain Matrix() CF for lightness adjustments

92ae58f338 Reland "bench: Add PhoneHub assets to skottie-vs-png decode bench"

71bcfef9f7 [skottie] Auto-resize and VAlign support for point text
Auto-resizing and vertical alignment require a non-empty text box.  But
currently, the presence of the text box is used to discriminate between
point text [1] and paragraph text [2].

In order to support auto-scaling and v-alignment for point text, we must
decouple the text mode encoding from the text box:

  * introduce and explicit LinebreakPolicy property for skottie::Shaper,
    and use it to control line breaking instead of the text box presence
  * by default, the line breaking policy is initialized per existing
    AE/BM semantics: non-empty text box -> paragraph mode,
    empty box -> point mode
  * the policy can be overridden via the PropertyObserver APIs to enable
    point mode auto-resizing and vertical alignment

Plumb layer size information and add machinery for retrieving layer

  * displacement source layer must be above (on top in stacking order)

  * if animated, the displacement layer timeline (in/out points) must
    fully cover the target layer timeline
  * Hue/Sat/Lightness selectors are not supported at the moment

These will be addressed in follow-up CLs.

Note: Bodymovin does not export hidden layers by default; if the
displacement source layer is hidden, one should select the "Hidden"
export option.

Assorted bugfixes for the non-analytical mask code path.

1) SkSG modulatePaint() should only override the blend mode when

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.

f2d90659ff [skottie] Fix analytical mask fill type
Sksg::Merge needs to preserve the fill type of the first path appended
in the stack.

Theoretically, one could append multiple paths with different fill types
using sksg::Merge, but in practice Skottie should never do that (append
mode with invertible shape only used for the very first mask in a stack).

71dc916852 [skottie] Pucker & Bloat shape layer vector effect
Observed semantics:

  -- operates on cubic Bezier path representation
  -- moves vertices towards the shape center, and control points in the
     opposite direction, based on the specified amount
  -- the center is determined as the vertex average
  -- the amount is specified as a fraction of the transition to center
     (0 -> noop, 1 -> fully collapesed to center)
  -- negative and extranormal amount values are allowed
     (invert direction/extrapolate)

AE allows selecting the paint order when both fill & stroke are present.

The CL also fixes some text stroke issues: stroke width not parsed

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)

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.
