Implementing b3DAccelerationExists and b3DAccelerationEnabled in dxdiagn

[Markus]

Hello,

can anyone tell me where to find information about the b3DAccelerationExists 
and b3DAccelerationEnabled properties in the display container returned by 
dxdiagn.dll and when they are supposed to be false or true?
In fact, MSDN does not seem to provide information about any of the properties 
returned by that dll.

Thanks,
