* A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)

* So in case PFD_STEREO is set, formats that support it should have priority above formats

*
* To summarize the following is most likely the correct behavior:
* stereo not set -> prefer no-stereo formats, else also accept stereo formats
* stereo set -> prefer stereo formats, else also accept no-stereo formats
* stereo don't care -> it doesn't matter whether we get stereo or not
*
* In Wine we will treat no-stereo the same way as don't care because it makes
* format selection even more complicated and second drivers with Stereo advertise
* each format twice anyway.
