    \brief The QAccelerometerReading class reports on linear acceleration

    The scale of the values is meters per second squared.
    The axes are arranged as follows.

    \image sensors-coordinates2.jpg

    A monoblock device sitting at rest, face up on a desk will experience
    a force of approximately 9.8 on the Z axis (ie. towards the roof).
    This is the proper acceleration the device experiences relative to
    freefall.
