The current implementation relies on SkShaper ascent values for top
text box alignment, but the results are not as visually accurate as AE
(or Lottie).
Use the computed tight bounds instead.

Some animations use humongous images which thrash Skia's resource caches
at raster time.
To avoid that, we can
1) force decoding upfront, when the animation is loaded
2) clamp the image size to something reasonable (2K^2)
Add a flag to support this operation mode, and enable for Skottie/WASM.

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.

Introduce a Skottie JSON extension for controlling vertical text

Refactor SkottieShaper to handle vertical adjustments based on a VAlign
enum:
kTop - the topmost line is ascent-aligned with the box top
(AE text-box behavior)
kTopBaseline - the topmost line is baseline-aligned with the top box
(AE text-point behavior)
kCenter - the text center is aligned with the box center
("sk_vj": 1, Skottie extension)
Also externalize the vertical adjustment as a text blob offset (instead
of baking into blob glyph offsets).

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

- 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

* 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

Camera layers introduce a top-level 3d camera/view matrix based on their
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
