17b9d1d1de [skottie] Initial Hue/Saturate effect support
Due to limitations in BodyMovin/AE JSX, full effect data is not
available (specifically the "channel range" property).

We only support static master hue, static master saturation and
static master lightness at this point.

This CL also introduces a new animation builder pattern:
DiscardableAdapterBase and attachDiscardableAdapter().

The former is a base class for adapters with full animator ownership.
This enables a) capturing raw adapter pointers in animator lambdas and
b) syncing to SG only once, after all local animators are updated).

The latter is a helper for managing adapter creation and optional
destruction (when all adapter properties are static we can discard it).

5f1108ce46 [skottie] Motion blur support
Unlike all other Skottie effects, motion blur requires sampling at multiple
points on the timeline.

To support this:

  1) Introduce MotionBlurEffect - a custom SG render node which can drive
     the timeline of its subtree using an sksg::Animator.

  2) Introduce MotionBlurController to swap for a regular LayerController
     when needed.  MotionBlurController dispatches time ticks to
     MotionBlurEffect instead of directly to the layer animators.

The actual motion blur impl is based on
https://skia-review.googlesource.com/c/skia/+/221416.

Motion blur requires Lottie files exported with this BodyMovin patch:
https://github.com/bodymovin/bodymovin-extension/pull/15

afd2c10c98 [skottie] Use hybrid bounds for custom Shaper VAlign modes
We used to rely solely on visual bounds for vertical alignment.  That
had the downside of leading/trailing empty lines being ignored.

Then https://skia-review.googlesource.com/c/skia/+/220916 switched to
using typographical bounds.  This approach produces results in line
with AE, but allows some glyphs to overflow the alignment boundary.

This CL introduces a hybrid approach:

1) for standard AE text alignment, continue to use typographical bounds

2) for Skottie VAlign extensions (sk_vj), use the union of typographical
   and visual bounds - this should mitigate both issues mentioned above

d7b321afa2 [skottie] Radial swipe effect
Implement radial wipe with a sweep gradient shader mask filter.

The implementation is slightly convoluted because edge feathering requires a real blur, which in turn requires content layer isolation.

So there are two distinct operation modes:

  - no feather -> draw the content directly into the dest buffer, with the mask filter
    deferred in SG context

  - feather -> draw the content into a separate layer, then blend (dstOut) the composed
    blur+shader mask on top

e695e53f1c [skottie] Add support for range selector domains
Range selector's "Based On" property controls how range indices map
to glyphs: characters, characters-excluding-spaces, words, lines.

To support this feature:

  - update SkottieShaper to track domain-relevant info per fragment
    (fLineIndex, fIsWhitespace)

  - update TextAdapter to build domain maps
    (domain index -> fragment span)

  - update RangeSelector to run its range indices through a domain map,
    if present.

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.

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).

SkShaper.
