Plumb layer size information and add machinery for retrieving layer
content as an SkPicture.
Implement the effect in SkSL.
Current limitations:
* displacement source layer must be above (on top in stacking order)
of the target layer
* 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
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.

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

Since we can't use mask filters on layer paints any longer, refactor the
existing wipe effects to use explicit shader masking:
- remove SkSG::MaskFilterEffect - it no longer works
- replace with SkSG::MaskShaderEffect
- for atomic draws, apply the shader to the draw paint as
SkShader::Blend(kSrcIn, mask_shader)
- 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!

All values can be animated independently (but of course!).

- expand the shape builder logic to allow local geometry adjustments
(kind of a bummer that dashing is a stroke/paint property as opposed
to a geometry effect in AE)

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

MotionBlurEffect makes use of many abilities some consider to be
unnatural. Notably, it mutates the state of its subtree at render time
(gasp) to sample various time points.
Mutation triggers scene graph invalidation, which bubbles up the
ancestor chain. While we immediately revalidate the subtree, we
cannot do the same for ancestors (no full scene knowledge). This means
post-rendering, we leave some SG nodes dirty - which triggers various
debug asserts).
The easiest fix is to temporarily suppress invalidation bubbling at the
MotionBlurEffect node level (this is safe, because we always revalidate
the subtree).
Also add a post-render assert for tighter state validation.

We're currently letting render context overrides (opacity, color
filters, blend mode, etc) spill down the descendent/mask content
tree.
This is not ideal, as mask content isolation breaks atomicity
assumptions for deferred overrides. Case in point: motion blur uses
SkBlendMode::kPlus to accumulate content "layers" - but since mask
content gets rendered into a separate layer, it fails to produce the
expected result.
The fix is to realize all context overrides on the top-level mask layer
(we already allocate this layer, so there's no reason to defer
downstream anyway).
