If you want the client to send the environment variables to the server
you rely on the client side GLX library to be from the DRI project. What
happens if you want to run a GLX app on a Sun workstation and want the
output on your PC with XF86 and DRI? I think the only sensible place for
a configuration file or whatever is on the server side. This is were the
user with his preferences and the 3D hardware sits.
For the same reason as above (other GLX client implementations) we
should not require any modifications to the GLX API. For identifying
client applications we have to use the means provided by standard X and
GLX.
