The current implementation applies constant coverage (outside selector

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.

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.

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

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

SkTArray is not a good choice for tigh allocations:
- its minimum allocation count is 8
- reserve(sz) doesn't adjust capacity to the exact value, but padds
the same way as normal growth (max(sz, 8, 50%))
- no shrink_to_fit() function to trim unneeded capacity
Since keyframed properties with a small number of frames are quite
common in Lottie, this adds significant heap overhead.
Switch to std::vector(), reserve() to the estimated frame count and
shrink_to_fit() when done parsing.
