well, reading „EGL version string: 1.5 (DRI2)“ when calling eglinfo I assumed
that DRI3 was somehow not working on my setup (see
<https://lists.freedesktop.org/archives/amd-gfx/2017-October/014544.html>, which
I've included in the commit message). Michel then cleared up, that the interface
meant by the EGL version string is an internal Mesa interface which has nothing
to do with the more widely known X11 protocol extension.

So I thought it best to clearly separate them. Ideally this internal interface
wouldn't be called "dri" at all, but I that's probably going a bit too far.

Ok, I'll resend in a minute with the correction to the commit message Michel
pointed out.

Cheers,
Kai
