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
to the interpreter soon.

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.

Currently just for image drawable, but going to use this for
references to other kinds of data in bindings, too.

Simplify burst handling. Scripts should just add to burst (if
they want to handle programmatic bursting, as well).
Update most effects to handle dynamic updates to position better,
and add a sample effect meant to be used with mouse tracking.

Also removed some older effects that weren't interesting, improved others,
cleaned up the unused functions in several, and renamed most of them to
reflect which feature they're demonstrating.
