OK, I've listened hard to the arguments on both sides and I
think I'm convinced that the realtime penalty for a context-
independent glGetFuncAddress is either negligable or zero.

However, as an application writer, I have to say that I have
no problem at all with the address returned by glGetFuncAddress
being context-specific.

It would be marginally nicer if it didn't have to be - but
in the interests of making life easier for the driver writers,
I think we should simply say in the spec that addresses returned
by glGetFuncAddress are *not* guaranteed to work in other contexts.

I would rather make it easy for all OpenGL's to implement
glGetFuncAddress with minimal code change than make it harder
to implement for such a small application-side gain. That
gives us a better chance of having this Linux specification
spread to other OS's - which is VERY important IMHO.
