I definitely think the GDA changes count as bugfixes; certainly they
bring us into line with NVIDIA's driver, which is effectively the GLX
spec at this point.  I'm not sure they're as correct as they need to be
- there's some discussion on bug #54080 that makes it sound like the
Rift SDK depends on more fields being filled in than what you'd get even
with this change - but I suspect that's actually Mesa's bug; and with
this change (and the ->loseContext thing already merged) Mesa can know
it can do the right thing and expect xserver not to crash as a result.
