Unfortunately not. Chris Bagwell and myself have been experimenting with quite a
few different approaches to extract touch information from the synaptics pads.
The present approach, to extract the bounding rectangle, is the best we can do,
I am afraid - at least with the information unveiled in Takashi's original
patch. In particular, rotation information is not reliably extractable.
