1275 * with the flag (PFD_STEREO / PFD_DOUBLEBUFFERING) set. Otherwise it says that it tries to match
1276 * formats without the given flag set.
1277 * A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)
1278 * has indicated that a format without stereo is returned when stereo is unavailable.
1279 * So in case PFD_STEREO is set, formats that support it should have priority above formats
1280 * without. In case PFD_STEREO_DONTCARE is set, stereo is ignored.
1282 * To summarize the following is most likely the correct behavior:
1283 * stereo not set -> prefer no-stereo formats, else also accept stereo formats
1284 * stereo set -> prefer stereo formats, else also accept no-stereo formats
1285 * stereo don't care -> it doesn't matter whether we get stereo or not
1287 * In Wine we will treat no-stereo the same way as don't care because it makes
1288 * format selection even more complicated and second drivers with Stereo advertise
1289 * each format twice anyway.
