A value of zero indicates the buttons on the transducer are aligned in the positive Y direction.

Dave providing me (off list) links to devices that support this data [3]. I think this would be a good property to consider for the V2 specification. -Jacob [1] http://msdn.microsoft.com/en-us/library/windows/desktop/hh454909(v=vs.85).aspx, http://msdn.microsoft.com/en-us/library/windows/desktop/hh454887(v=vs.85).aspx [2] http://lists.w3.org/Archives/Public/public-pointer-events/2013AprJun/0005.html [3] https://store.wacom.com/us/en/product/KP701E2/ (and other Wacom Pro products)
