Microtask queue scheduler for the browser. Falls back to
window.requestAnimationFrame in environments that don't allow
MutationObserver based scheduling.
The microtask queue is a set of tasks that runs at the start of the next frame
in the browser. This is analogous to
process.setImmediate() in Node. There's
no direct API for the microtask queue in the browser, but using
document.MutationObserver we can trick the browser into running functions as
part of the microtask queue. This is useful to create tight, 60fps loops in the
main browser thread.
