Ah, I was unaware of your prior work. FWIW I also sent an X server
patch, and Adam Jackson fixed it up and sent a more complete version.

If that's the case, __DRI_API_GLES3 should be removed. When it is,
this code can also be updated. It's all mostly theoretical, since in
practice no mesa driver will set __DRI_API_GLES3 without also setting
GLES2.
If you'd prefer your patches get merged, that's fine with me, but I do
want to get something in so that we can actually run dEQP without
patching it to request a 2.0 context.
Cheers,
