    \brief Interface for a Qt3D frame advance service.

    This is an interface class that should be subclassed by providers of the
    frame advance service. When used with the Renderer aspect, the aspect needs to
    be the one providing the ticks depending on the vertical refresh rate. When
    used with no Renderer aspect, a default tick clock implementation can be
    used.
