/* 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
