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

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).

Two issues:
1) Empirically (per AE's model), only solid layers transform the effect space.
All other layer types implement their effects ignoring the layer xform.
2) Due to the effect deferral mechanism in sksg, shader effects are
sometimes applied with a different transform than intended.
To address #1, tweak the layer builder logic to attach the effects
before/after the transform node, depending on the layer type.
For #2, track the CTM active when the shader effect is attached and undo
any intervening transformations via a local matrix when the shader is
actually applied to SkPaint.

This differed from the separate versions in that it snapped to zero.
It was also strictly worse than calling the two separate versions.
Most clients don't need the snapping, so just call the two existing
functions. For clients that need the snapping, call new variants of
each that do snap.

Implement gradient ramp using SG shader effects.
A couple of quirks:
- since the gradient type (linear/radial) is animatiable (?!),
update sksg::ShaderEffect to allow resetting the shader
- gradient ramp doesn't have an assigned/stable JSON effect type,
but the data is present; introduce a name-based effect lookup method
(used as a fallback when the type is not recognized)

Currently, gradients are PaintNode subclasses - which limits their
applicability to leaf DAG nodes.
In order to support generalized gradient/shader effects:
* introduce a new Shader base class
* refactor gradients as Shader subclasses
* introduce ShaderPaint (to support current Gradient-as-paint use)
* introduce ShaderEffect (to support future Gradient-as-effect use)
Tangentially:
* rename SkSGPaintNode.h -> SkSGPaint.h
* consolidate sksg::Color into SkSGPaint.h

transform properties:
* position - camera location
* point of interest (stored as anchor point by BM) - camera direction
* rotation - camera orientation
The perspective degree is controlled by a "zoom" camera property (which
corresponds to the view distance), and the composition dimensions.
Current limitations:
* single camera track/layer
* affects all layers (not just 3d-tagged layers)
* parent layer transforms are likely not applied correctly

AE supports two text layout modes [1]:
* point text: text is laid out on an infinite line, starting at the given position,
and observing explicit line breaks only; in this case the text baseline is at the
given position.
* paragraph (box) text: text is laid out within the given box, using line breaks to
fit.
This CL implements the latter mode, in addition to the already supported point mode:
- parse & plumb the text box info
- update the text adapter logic to use SkShaper's width-constrained shaping mode
- tangentially, fix sksg::TextBlob's bounds computation

- Collapsed the per-particle data into a single struct, and
use that to communicate with drawables, too. Let the drawables
manage allocation of xforms, colors, etc. Helpful for non-atlas
drawables, and just to keep the effect code simpler.
- Having all of the params in a single struct allows us to move
the remaining animated behaviors into affectors (color/frame).
- Added SkColorCurve, which works like SkCurve for SkColor4f.
Use that to create a color affector (rather than simple
start/end colors in the effect params).
- Also put the stable random in SkParticleState. This is going
to be necessary if/when we change affectors to operate on all
particles (rather than one at a time). Still need to move t
value into the particle struct (or eval it from the lifetime
params on demand).
