++ \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.
