Touch ellipses are symmetrical by default. For devices capable of true 360
degree orientation, the reported orientation must exceed the range max to
indicate more than a quarter of a revolution. For an upside-down finger,
range max * 2 should be returned.
Orientation can be omitted if the touch area is circular, or if the
information is not available in the kernel driver. Partial orientation
support is possible if the device can distinguish between the two axis, but
support is possible if the device can distinguish between the two axes, but
not (uniquely) any values in between. In such cases, the range of
