Re: [Public WebGL] GL_MAX_TEXTURE_SIZE power of two ?

I disagree that it should be removed, though I can understand the desire to not have it listed as a difference. Nevertheless, I think we should state it explicitly, perhaps as a note regarding the interpretation of that passage.

The new subsection has been removed from the Editor's Draft and the
associated conformance test has been updated to point out where in the
GLES 2.0 spec the power-of-two implication comes from. See
https://github.com/KhronosGroup/WebGL/pull/331 .

Jeff, Guillaume, if you feel strongly about this then please raise the
issue either with the OpenGL ES working group, or call for a formal
vote in the WebGL WG.
