[PW CE C#] Whats the content of PWSpatialWrapper.dll delivered with MostOfDavesClasses?

Together with MostOfDavesClasses there are two dll's, PWSpatialWrapper and PWSpatialWrapperX64 but they are not references anywhere in MostOfDavesClasses.cs.

I'm looking for a way to run a Saved Search with a spatial critera and think that might be something in those wrappers.
