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

469 * extension list which causes this extension not to be listed. (Wine requires this extension).

1059 * A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)
1060 * has indicated that a format without stereo is returned when stereo is unavailable.
1061 * So in case PFD_STEREO is set, formats that support it should have priority above formats
1062 * without. In case PFD_STEREO_DONTCARE is set, stereo is ignored.
1064 * To summarize the following is most likely the correct behavior:
1065 * stereo not set -> prefer no-stereo formats, else also accept stereo formats
1066 * stereo set -> prefer stereo formats, else also accept no-stereo formats
1067 * stereo don't care -> it doesn't matter whether we get stereo or not
1069 * In Wine we will treat no-stereo the same way as don't care because it makes
1070 * format selection even more complicated and second drivers with Stereo advertise
