We want EGL_CONTEXT_OPENGL_ROBUST_ACCESS (note missing _EXT) here.
For whatever reason the two differ 0x31B2 vs 0x30BF (according to the
includes in mesa).

While working on a similar version specific EGL bits, I've added a
single boolean as it seemed easer/shorter to check (yes I'm that
lazy).
Just throwing the idea out there, unless others insist you don't have
to do any of that.
