|

* 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.
