Virtual-WebGL (share resources + more contexts)

[Gregg Tavares]

Just passing this on. I wrote a WebGL / WebGL2 wrapper that simulates multiple webgl contexts on top of a single actual webgl context.

https://github.com/greggman/virtual-webgl

I'd actually written it a while ago but that version queried the state and was too slow. I updated it to shadow the state and now it's fast.

Uses include

(*) sharing resources across contexts / libraries.
(*) using more contexts than the browser itself allows

I mostly wrote it just as something fun to try to write but recently someone had a real need which led to the update.

This is a super useful library! Multiple customers have requested this functionality recently. Thanks Gregg for writing this and sharing it!

Thanks a lot Gregg. 

This is exactly what I was looking for to build a 'material palette' where I need webgl rendering to lots of small canvases.
