Thanks for this list -- it's great, exactly what I was hoping for.  I've
re-exported all these symbols in my current tree, so hopefully it should
be fine.

Yeah, it's a fair shout.  A lot of it was semi-automated: I just
generated a massive list of unused symbols and their definition sites,
did a couple of sweeps of manual sanity-checking and culling, but by the
time I'd unexported the millionth symbol, certainly some less sensible
changes may have slipped through the cracks. :)

I'm taking another, closer, look at all the changes before I send out
v3, and will re-export anything I can see -- like ChangePicture -- which
should probably stay ABI.

Hmm, I don't think either Xserver-spec.xml or ddx-design.xml need
changes, since this only affects Xorg modules; the DIX<->DDX interface
hasn't really changed in any way.  Both documents could definitely do
with some love though ...

Thanks again for the review!
