463 *
464 * The main problem for our OpenGL code is that we need certain GLX calls but their presence
465 * depends on the reported GLX client / server version and on the client / server extension list.
466 * Those don't have to be the same.
467 *
468 * In general the server GLX information lists the capabilities in case of indirect rendering.
469 * When direct rendering is used, the OpenGL client library is responsible for which GLX calls are
470 * available and in that case the client GLX informat can be used.
471 * OpenGL programs should use the 'intersection' of both sets of information which is advertised
472 * in the GLX version/extension list. When a program does this it works for certain for both
473 * direct and indirect rendering.
474 *
475 * The problem we are having in this area is that ATI's Linux drivers are broken. For some reason
476 * they haven't added some very important GLX extensions like GLX_SGIX_fbconfig to their client
477 * extension list which causes this extension not to be listed. (Wine requires this extension).
478 * ATI advertises a GLX client version of 1.3 which implies that this fbconfig extension among
479 * pbuffers is around.
480 *
481 * In order to provide users of Ati's proprietary drivers with OpenGL support, we need to detect
482 * the ATI drivers and from then on use GLX client information for them.

1024 * is not very clear on MSDN. They specify that ChoosePixelFormat tries to match pixel formats
1025 * with the flag (PFD_STEREO / PFD_DOUBLEBUFFERING) set. Otherwise it says that it tries to match
1026 * formats without the given flag set.
1027 * A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)
1028 * has indicated that a format without stereo is returned when stereo is unavailable.
1029 * So in case PFD_STEREO is set, formats that support it should have priority above formats
1030 * without. In case PFD_STEREO_DONTCARE is set, stereo is ignored.
1031 *
1032 * To summarize the following is most likely the correct behavior:
1033 * stereo not set -> prefer no-stereo formats, else also accept stereo formats
1034 * stereo set -> prefer stereo formats, else also accept no-stereo formats
1035 * stereo don't care -> it doesn't matter whether we get stereo or not
1036 *
1037 * In Wine we will treat no-stereo the same way as don't care because it makes
1038 * format selection even more complicated and second drivers with Stereo advertise
1039 * each format twice anyway.
