464 * OpenGL programs should use the 'intersection' of both sets of information which is advertised
465 * in the GLX version/extension list. When a program does this it works for certain for both
466 * direct and indirect rendering.
468 * The problem we are having in this area is that ATI's Linux drivers are broken. For some reason

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

1090 * with the flag (PFD_STEREO / PFD_DOUBLEBUFFERING) set. Otherwise it says that it tries to match
1091 * formats without the given flag set.
1092 * A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)
1093 * has indicated that a format without stereo is returned when stereo is unavailable.
1094 * So in case PFD_STEREO is set, formats that support it should have priority above formats
1095 * without. In case PFD_STEREO_DONTCARE is set, stereo is ignored.
1097 * To summarize the following is most likely the correct behavior:
1098 * stereo not set -> prefer no-stereo formats, else also accept stereo formats
1099 * stereo set -> prefer stereo formats, else also accept no-stereo formats
1100 * stereo don't care -> it doesn't matter whether we get stereo or not
1102 * In Wine we will treat no-stereo the same way as don't care because it makes
1103 * format selection even more complicated and second drivers with Stereo advertise
1104 * each format twice anyway.
