The old factory is deprecated. The new factory does stricter checking on
the signature of main and calls to sample - verifying that the SkSL is
valid as an SkShader (vs SkColorFilter) at effect creation time.

Aiming to describe the interesting ways that we diverge from GLSL,
focused on semantics, not syntax. Left a placeholder for coordinates,
putting together good examples for things takes time, so I want to land
this in pieces.

I hit this while diagnosing the type coercion error).

uint (and bitwise operations) aren't supported by our minimum spec, and
they're going to be removed from public SkSL. For now, convert the
random generator to a good-enough chaotic sequence of high-frequency
sine waves.
If/when the interpreter (and particles) are converted to the newer skvm
backend, it will be straightforward to support custom intrinsics that
emit skvm instructions directly into the builder, and re-introduce a
better integer-based PRNG, without requiring SkSL language support.

This is a massive breaking change for all existing users of CanvasKit.
It will be (one of the only) changes in 0.19.0 to make the transition
easier.
Suggested reviewing order:
- index.d.ts (to see type changes). Notice SkPicture still has Sk
prefix, but no other types do (this felt "right" since Sk is
part of the name of the type, but I can be swayed on this).
- canvaskit-wasm-tests.ts
- tests/*.spec.js
- interface.js and helper.js
- html examples
- markdown files
