/* 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 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.
