[Mesa-dev] [PATCH] mesa: add drawbuffer argument to ClearNamedFramebufferfi

[Ilia Mirkin]

This was fixed in revision 47 of the ARB_dsa spec in Oct 22, 2015. Since
it's horrible to have differing APIs across library versions, we should
attempt to minimize the impact by backporting it as far as possible and
hope no one notices.

If people are good with this, I'll also nominate the glext.h header update for stable.
