I always have a heck of a time finding the written specifications for parts of the X11 protocol.  Is there some central place for these things?  Right now I'm looking for the specification for the GLX extension, to look at which requests yield which errors, and which versions of GLX support which requests. More generally, where would I find this sort of thing for any of the extensions?
