I'm not sure what this means. Do you mean that we plan to contribute this back to Khronos?

Can be enum class, and use VAO rather than Vao

Oops.

That's the hope. I have a bunch of conformance tests from the test suite that were extension tests but I changed all the calls to treat the extension stuff as core to WebGL2. Hoping to contribute that back to Khronos since their WebGL2 tests right now look like they need some work (looks like they were mostly just copy pasted from a previous suite and then a WebGL2 context was queried...)

It broke the Apple Windows build as the EWS noticed it in time.

http://trac.webkit.org/changeset/181589 will cause problems.  glBindVertexArray et al. are in GLESv3.  I carefully made gl2softlinking.h to have everything and only everything that is in GLESv2.  It should crash every time it looks for those functions. This change should be reverted and replaced by proper separation of WebGL and WebGL2.

Reported on bug 145156 a related regression.
