    GimpToolGyroscope is a tool widget providing canvas interaction for
    3D rotation.  The widget doesn't preset a UI, but rather
    facilitates panning, rotation, and zoom, by dragging the canvas, or
    using the keyboard.
    Rotation is expressed using yaw/pitch/roll angles (performed in
    this order).  A zoom factor can be specified, which affects the
    magnitude of the rotation per distance traveled.  The widget can
    operate in inverse mode, performing an inverse transformation.
