This enforces an even stricter version of the rules from GLSL ES 1.0
Appendix A, Section 5. Essentially, indices (to arrays, vectors,
matrices) must be made of literals, loop indices, and expressions made

Also fix a crash if you try to play an effect that has never compiled

to set "dt" -- this code is all going to be reworked soon for SkVM, but
I hit this while diagnosing the type coercion error).

This was unnecessary (closed-form unit-disc picking is simpler), and
these loops don't meet the strict ES2 standards that we'll be applying

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.

The previous behavior leaked Skia-internal concepts into public SkSL.
Users coming from GLSL will expect that bindable/sampleable objects are
uniform (just like texture2D). This keeps the old support around (and
tested), but updates all of our examples to use 'uniform'.

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

There is no more 'inout half4 color'. Effects return their output color.
If an effect wants the input color, it must use the (already existing)
approach of sampling a nullptr input shader.
The change is guarded for Chromium (so we can update their runtime color
filters in skia_renderer.cc).
For the GPU backend, FPs can now override usesExplicitReturn to indicate
that their emitCode will generate a return statement. If that's true,
then writeProcessorFunction doesn't inject the automatic return of the
output color, and emitFragProc will *always* wrap that FP in a helper
function, even as a top-level FP. GrSkSLFP opts in to this behavior, so
that the user-supplied return becomes the actual return in the FP's
emitCode.
Adapting the skvm code to this wasn't too bad: It looks fragile (what
happens if there are multiple returns?), but that's not really possible
today, without varying control flow.

When I joined the team, I had a hard time interpreting some of the
Quickstart steps. If you run them as presented, you get seven different
output directories. I've added some text to explain that you don't
actually need this many, and I've also fixed an anchor link.
I made these edits in http://cider/ for its excellent previewing
capabilities, and Cider automatically reformatted and rewrapped the
Markdown to match google3 standards. (e.g. using # and ## to denote
sections, wrapping code blocks in ```.) This doesn't affect the
generated output.

In https://skia-review.googlesource.com/c/skia/+/291182 emscripten was updated
to 1.39.16. This introduced a breaking API change to the CanvasKit
initialization callback, which becomes simply `then()` as opposed to
`ready().then()`. In the course of this change, I missed a few `ready()` calls,
which has broken the examples in public-facing documentation.
E.g. https://skia.org/user/modules/canvaskit. This CL fixes that.
