Supporting Usages in Touch Digitizer Drivers (Windows 7)

• http://msdn.microsoft.com/en-us/library/windows/hardware/ff553737(v=vs.85).aspx
• Required

  0x42	Tip switch	Use the tip switch to indicate finger contact and liftoff from the digitizer surface, similar to how a pen reports contact with the digitizer.
  0x32	In-range	If the device supports z-axis detection, it reports in-range when the transducer is within the region where digitizing is possible. If the device does not support z-axis detection, the driver should set in-range and tip switch when a finger comes in contact with the digitizer.
