 172          * with the flag (PFD_STEREO / PFD_DOUBLEBUFFERING) set. Otherwise it says that it tries to match
 173          * formats without the given flag set.
 174          * A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)
 175          * has indicated that a format without stereo is returned when stereo is unavailable.
 176          * So in case PFD_STEREO is set, formats that support it should have priority above formats
 177          * without. In case PFD_STEREO_DONTCARE is set, stereo is ignored.
 178          *
 179          * To summarize the following is most likely the correct behavior:
 180          * stereo not set -> prefer non-stereo formats, but also accept stereo formats
 181          * stereo set -> prefer stereo formats, but also accept non-stereo formats
 182          * stereo don't care -> it doesn't matter whether we get stereo or not
 183          *
 184          * In Wine we will treat non-stereo the same way as don't care because it makes
 185          * format selection even more complicated and second drivers with Stereo advertise
 186          * each format twice anyway.
