Hi Benjamin,

thanks for the fix. We still need to solve
https://bugs.freedesktop.org/show_bug.cgi?id=34042 in Mesa before having
a working egl backend.

In case the Mesa fix is delayed, we can work around it by having a
"dummy" EGLContext and use it whenever we try to make a surfaceless
context current. This is a last resort, of course, and I hope that we
won't need to go that way (unless we decide that we want to be
compatible with Mesa versions not having the fix).

Thanks,
Alexandros
