Re: [w3ctag/design-reviews] Review OffscreenCanvas, including ImageBitmapRenderingContext (#141)

@toji the API you propose does not address the use case brought forward by @juj. That is to say the case of porting apps to the web via WebAssambly which were not developed using an async programming model.
We need to decide whether or not this is a use case that the Web Platform should support.  Not supporting this means emscripten will have to use a gpu command protocol (implemented on top of SharedArrayBuffer, I presume) in order to relay WebGL commands to a separate Worker.  This is not great for performance, but it is a possible.

@juj do you have performance data regarding the perf impact of relaying WebGL Commands?
