Determine DirectX an app uses #227

Is it possible for DDrawCompat to determine what version of DirectX an application is based on? I cannot find anything about it in log files.

Why do you need to know? The proper answer could depend on that.

For DirectDraw specifically, you could try to guess the minimum needed version based on which interfaces are used by looking at the debug logs. But that might not be entirely accurate either, since an application might depend e.g. on bug fixes in later DirectX releases, and they aren't required to use the latest available interface versions. A game might ship with DirectX 6 but use only DirectDraw interfaces available in DirectX 3. Also, DirectX consists of other components too, like DirectSound and DirectInput, and games could be compatible with different versions of each. It's probably best to refer to the particular game's documentation, or check which version ships with its install media.
