460 * In general the server GLX information lists the capabilities in case of indirect rendering.

463 * OpenGL programs should use the 'intersection' of both sets of information which is advertised
464 * in the GLX version/extension list. When a program does this it works for certain for both
465 * direct and indirect rendering.
467 * The problem we are having in this area is that ATI's Linux drivers are broken. For some reason
468 * they haven't added some very important GLX extensions like GLX_SGIX_fbconfig to their client
469 * extension list which causes this extension not to be listed. (Wine requires this extension).

471 * pbuffers is around.

1092 /* The behavior of PDF_STEREO/PFD_STEREO_DONTCARE and PFD_DOUBLEBUFFER / PFD_DOUBLEBUFFER_DONTCARE
1093 * is not very clear on MSDN. They specify that ChoosePixelFormat tries to match pixel formats
1094 * with the flag (PFD_STEREO / PFD_DOUBLEBUFFERING) set. Otherwise it says that it tries to match
1095 * formats without the given flag set.
1096 * A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)
1097 * has indicated that a format without stereo is returned when stereo is unavailable.
1098 * So in case PFD_STEREO is set, formats that support it should have priority above formats
1099 * without. In case PFD_STEREO_DONTCARE is set, stereo is ignored.
1101 * To summarize the following is most likely the correct behavior:
1102 * stereo not set -> prefer no-stereo formats, else also accept stereo formats
1103 * stereo set -> prefer stereo formats, else also accept no-stereo formats
1104 * stereo don't care -> it doesn't matter whether we get stereo or not
1106 * In Wine we will treat no-stereo the same way as don't care because it makes
1107 * format selection even more complicated and second drivers with Stereo advertise
1108 * each format twice anyway.
