<pre>(This is with reference to src/glx/glxcmds.c; other implementations in the tree
might have similar issues, I haven't checked)
In principle you might want to query GLX_VENDOR_NAMES_EXT if you're trying to
do something clever with glvnd; other strings are imaginable for other possible
extensions. But at the moment the call to __glXQueryServerString is
unreachable, because of the 'default: return NULL;' in the switch statement.
Part of the reason for this is that the `priv->serverXXX` strings are saved in
the GLX display state and are manually freed at shutdown. If we returned
arbitrary strings too, we'd need to track them in a hash table; and once you're
doing that, why not do that for _all_ server strings.
This probably also requires making __glXQueryServerString robust against
getting errors instead of replies.</pre>
