+ * Higher level services /may/ perform this transformation.

+ * /
+ * |/ z>0 (toward the sky)
+ *
+ * O: Origin (x=0,y=0,z=0)
+ *
+ *
+ * Orientation
+ * -----------
+ *
+ * All values are angles in degrees.
+ *
+ * Orientation sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
+ * azimuth: angle between the magnetic north direction and the Y axis, around
+ * the Z axis (0<=azimuth<360).
+ * 0=North, 90=East, 180=South, 270=West
+ *
+ * pitch: Rotation around X axis (-180<=pitch<=180), with positive values when
+ * the z-axis moves toward the y-axis.
+ *
+ * roll: Rotation around Y axis (-90<=roll<=90), with positive values when
+ * the x-axis moves towards the z-axis.
+ *
+ * Note: For historical reasons the roll angle is positive in the clockwise
+ * direction (mathematically speaking, it should be positive in the
+ * counter-clockwise direction):

+ * Y
+ * note that +Y == -roll
+ *
+ *
+ *
+ * Note: This definition is different from yaw, pitch and roll used in aviation
+ * where the X axis is along the long side of the plane (tail to nose).
+ *
+ *
+ * Acceleration
+ * ------------
+ *
+ * All values are in SI units (m/s^2) and measure the acceleration of the
+ * device minus the force of gravity.
+ *
+ * Acceleration sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
+ * x: Acceleration minus Gx on the x-axis
+ * y: Acceleration minus Gy on the y-axis
+ * z: Acceleration minus Gz on the z-axis
+ *
+ * Examples:
+ * When the device lies flat on a table and is pushed on its left side
+ * toward the right, the x acceleration value is positive.
+ *
+ * When the device lies flat on a table, the acceleration value is +9.81,
+ * which correspond to the acceleration of the device (0 m/s^2) minus the
+ * force of gravity (-9.81 m/s^2).
+ *
+ * When the device lies flat on a table and is pushed toward the sky, the
+ * acceleration value is greater than +9.81, which correspond to the
+ * acceleration of the device (+A m/s^2) minus the force of
+ * gravity (-9.81 m/s^2).
+ *
+ *
+ * Magnetic Field
+ * --------------
+ *
+ * All values are in micro-Tesla (uT) and measure the ambient magnetic
+ * field in the X, Y and Z axis.
+ *
+ * Magnetic Field sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
+ * Gyroscope
+ * ---------
+ * All values are in radians/second and measure the rate of rotation
+ * around the X, Y and Z axis. The coordinate system is the same as is
+ * used for the acceleration sensor. Rotation is positive in the
+ * counter-clockwise direction (right-hand rule). That is, an observer
+ * looking from some positive location on the x, y or z axis at a device
+ * positioned on the origin would report positive rotation if the device
+ * appeared to be rotating counter clockwise. Note that this is the
+ * standard mathematical definition of positive rotation and does not agree
+ * with the definition of roll given earlier.
+ * The range should at least be 17.45 rad/s (ie: ~1000 deg/s).
+ *
+ * Proximity
+ * ---------
+ *
+ * The distance value is measured in centimeters. Note that some proximity
+ * sensors only support a binary "close" or "far" measurement. In this case,
+ * the sensor should report its maxRange value in the "far" state and a value
+ * less than maxRange in the "near" state.
+ *
+ * Proximity sensors report a value only when it changes and each time the
+ * sensor is enabled. setDelay() is ignored.
+ *
+ * Light
+ * -----
+ *
+ * The light sensor value is returned in SI lux units.
+ *
+ * Light sensors report a value only when it changes and each time the
+ * sensor is enabled. setDelay() is ignored.
+ *
+ * Pressure
+ * --------
+ *
+ * The pressure sensor value is returned in hectopascal (hPa)
+ *
+ * Pressure sensors report events at a constant rate defined by setDelay().
+ *
+ * Gravity
+ * -------
+ * A gravity output indicates the direction of and magnitude of gravity in the devices's
+ * coordinates. On Earth, the magnitude is 9.8. Units are m/s^2. The coordinate system
+ * is the same as is used for the acceleration sensor.
+ * When the device is at rest, the output of the gravity sensor should be identical
+ * to that of the accelerometer.
+ *
+ * Linear Acceleration
+ * -------------------
+ * Indicates the linear acceleration of the device in device coordinates, not including gravity.
+ * This output is essentially Acceleration - Gravity. Units are m/s^2. The coordinate system is
+ * the same as is used for the acceleration sensor.
+ * The output of the accelerometer, gravity and linear-acceleration sensors must obey the
+ * following relation:
+ *
+ * acceleration = gravity + linear-acceleration
+ *
+ *
+ * Rotation Vector
+ * ---------------
+ * A rotation vector represents the orientation of the device as a combination
+ * of an angle and an axis, in which the device has rotated through an angle
+ * theta around an axis <x, y, z>. The three elements of the rotation vector
+ * are <x*sin(theta/2), y*sin(theta/2), z*sin(theta/2)>, such that the magnitude
+ * of the rotation vector is equal to sin(theta/2), and the direction of the
+ * rotation vector is equal to the direction of the axis of rotation. The three
+ * elements of the rotation vector are equal to the last three components of a
+ * unit quaternion <cos(theta/2), x*sin(theta/2), y*sin(theta/2), z*sin(theta/2)>.
+ * Elements of the rotation vector are unitless. The x, y, and z axis are defined
+ * in the same was as for the acceleration sensor.
+ *
+ * The rotation-vector is stored as:
+ *
+ * sensors_event_t.data[0] = x*sin(theta/2)
+ * sensors_event_t.data[1] = y*sin(theta/2)
+ * sensors_event_t.data[2] = z*sin(theta/2)
+ * sensors_event_t.data[3] = cos(theta/2)
+ *
