requestAnimationFrame in WorkerGlobalScope

[svoisen]

Description

Allows use of requestAnimationFrame in web workers.

Currently this is unsupported in WebKit.

Rationale

This is necessary for any applications that wish to perform tasks such as animation rendering off the main thread, perhaps in conjunction with OffscreenCanvas.

Specification

https://html.spec.whatwg.org/multipage/imagebitmap-and-animations.html#dom-animationframeprovider-requestanimationframe

Tests

I see that the test here is tentative. @Ms2ger you added this in web-platform-tests/wpt#12293, do you know if it still needs to be tentative?

[Ms2ger]

Looks like the spec change merged in whatwg/html#3677 (Aug 27, 2018) and I marked it as tentative on Aug 3, 2018, so we'd only be four years late marking it not tentative

You say "perhaps", but is there any use-case for this without OffscreenCanvas?
