215 and MINOR are the major and minor axis of an ellipse. The orientation of
216 the touch ellipse can be described with the ORIENTATION parameter, and the
217 direction of the finger ellipse is given by the vector (a - b).
269     The orientation of the touching ellipse. The value should describe a signed
271     range is arbitrary, but zero should be returned for an ellipse aligned with
272     the Y axis (north) of the surface, a negative value when the ellipse is
273     turned to the left, and a positive value when the ellipse is turned to the
