Windows: correct tablet stylus rotation to range -180..180 degrees
When the user holds the Wacom Art Pen straight, rotation is zero;
when turning it counter-clockwise, it should have a negative angle,
whereas the driver sends a positive angle multiplied by 10;
when turning it clockwise it should have a positive angle up to 180,
whereas the driver sends 360 * 10 going downwards towards 180 * 10.
These corrections make the angle reading the same between Linux and
Windows.
