Re: [Public WebGL] Compute shaders



I anticipate computer shaders will happen in some >2.0 version of WebGL. We've already decided that they won't make it into core WebGL 2.0.

The turnaround time for a hypothetical WebGL 2.1 should be much lower than the 1.0->2.0 upgrade.

I'm not sure why a minor release number was chosen by Khronos for ES 3.1.
But the number of features introduced by OpenGL ES 3.1 does seem to me
rather major. OpenGL ES 3.1 is also following over 2 years after OpenGL ES
3.0, which is the usual release cycle by Khronos for major releases.
