[whatwg] Canvas in workers

[Jeff Gilbert]

This is not the current WebGL semantics:
    WebGL presents its drawing buffer to the HTML page compositor immediately before a compositing operation[...]

I can't find where this is specified for canvas, though I assume it's all implied.

We talked through this proposal with a lot of Mozilla people in a meeting
and collectively decided that we don't care about the case of workers that
commit multiple frames to a canvas without yielding --- at least for now.
So we want to remove commit() and copy the main-thread semantics that a
canvas frame is eligible for presentation whenever script is not running in
the worker.
