* Those don't have to be the same.
*
* In general the server GLX information should be used in case of indirect rendering. When direct
* rendering is used, the OpenGL client library is responsible for which GLX calls are available.
* Nvidia's OpenGL drivers are the best in terms of GLX features. At the moment of writing their
* 8762 drivers support 1.3 for the server and 1.4 for the client and they support lots of extensions.
* Unfortunately it is much more complicated for Mesa/DRI-based drivers and ATI's drivers.
* Both sets of drivers report a server version of 1.2 and the client version can be 1.3 or 1.4.
* Further in case of atleast ATI's drivers one crucial extension needed for our pixel format code
* is only available in the list of server extensions and not in the client list.
*
