I will happily renamespace the remaining DRI1 code in libGL to avoid
that kind of confusion, if it helps.  I have at least one product where
I'm going to have to ship both updated DRI2 and extant DRI1 drivers for
the forseeable future, so I really want not to need two libGL's.

Apologies for reviving the thread, I was delightfully far from a
computer for the past two weeks.  But what a nice thing to give me as a
welcome home present!  Having started my interest in Mesa on tdfx and
mach64 I'm entirely pleased to see them in the dustbin.
