/* In case of GLX you have direct and indirect rendering. Most of the time direct rendering is used

* The main problem for our OpenGL code is that we need certain GLX calls but their presence
* depends on the reported GLX client / server version and on the client / server extension list.
* Those don't have to be the same.
*
* In general the server GLX information lists the capabilities in case of indirect rendering.
* When direct rendering is used, the OpenGL client library is responsible for which GLX calls are
* available and in that case the client GLX informat can be used.
* OpenGL programs should use the 'intersection' of both sets of information which is advertised
* in the GLX version/extension list. When a program does this it works for certain for both
* direct and indirect rendering.
*
* The problem we are having in this area is that ATI's Linux drivers are broken. For some reason
* they haven't added some very important GLX extensions like GLX_SGIX_fbconfig to their client
* extension list which causes this extension not to be listed. (Wine requires this extension).
* ATI advertises a GLX client version of 1.3 which implies that this fbconfig extension among
* pbuffers is around.
*
* In order to provide users of Ati's proprietary drivers with OpenGL support, we need to detect
* the ATI drivers and from then on use GLX client information for them.

* A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)

* To summarize the following is most likely the correct behavior:
* stereo not set -> prefer no-stereo formats, else also accept stereo formats
* stereo set -> prefer stereo formats, else also accept no-stereo formats
* stereo don't care -> it doesn't matter whether we get stereo or not
*
* In Wine we will treat no-stereo the same way as don't care because it makes
* format selection even more complicated and second drivers with Stereo advertise
