Summary: Support loading ResourceLoader modules into Web
Workers
Product: MediaWiki

Some more CPU intensive client side multimedia tools may need to do background
processing in the future.
Browsers support running JavaScript background processes through the Web
Workers API --

However there are some complications:
* workers run in their own JS context, so the JS file loaded must be self
contained
* worker source code must be loaded from the web page's origin, which could be
problematic when RL is being used on a second domain such as bits. There may be
workarounds such as using blob URLs...
Note that workers communicate with the parent page through post message similar
to iframes.
