/* The behavior of PDF_STEREO/PFD_STEREO_DONTCARE and PFD_DOUBLEBUFFER / PFD_DOUBLEBUFFER_DONTCARE
* is not very clear on MSDN. They specify that ChoosePixelFormat tries to match pixel formats
* with the flag (PFD_STEREO / PFD_DOUBLEBUFFERING) set. Otherwise it says that it tries to match
* formats without the given flag set.
* A test on Windows using a Radeon 9500pro on WinXP (the driver doesn't support Stereo)
* has indicated that a format without stereo is returned when stereo is unavailable.
* So in case PFD_STEREO is set, formats that support it should have priority above formats
* without. In case PFD_STEREO_DONTCARE is set, stereo is ignored.
*
* To summarize the following is most likely the correct behavior:
* stereo not set -> prefer non-stereo formats, but also accept stereo formats
* stereo set -> prefer stereo formats, but also accept non-stereo formats
* stereo don't care -> it doesn't matter whether we get stereo or not
*
* In Wine we will treat non-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.
