I don't really understand what a drawing buffer is in this API.
Why wouldn't you just do:
gl = new WebGLRenderingContext();
In any case, I think it can be made any number of ways, the only important
thing at this point to make sure it works consistently with the 2D context
and in particular to make sure it works in Worker threads is to use the
API described here:
Specifically, the bit starting "it will require some additions to WebGL".
