GPU modes in Firefox not supported when running in workers.

[qmalvido]

What is wrong?

When trying to instance gpujs within a javascript worker using Firefox we get the error: "Error: A requested mode of "gpu" and is not supported" It happens with all modes except for "cpu". If the mode is not specified it seems to fall back to "cpu".

Where does it happen?

It happens at the time of instancing the object inside the worker.

How do we replicate the issue?

Please, see attached code: "issue.html" tries to create a worker using "issue-worker.js" issues.zip

How important is this (1-5)?

Expected behavior (i.e. solution)

It should create an instance in the specified mode matching the behavior in the main thread in Firefox.
