    (3) causing an oldest frame buffer in said queue to be displayed, wherein said oldest frame buffer is unnamed;

    (4) naming a frame buffer not in said queue to be a back buffer;

    (5) enabling rendering of an entire frame into said back buffer; and

    (6) removing said oldest frame buffer from said queue after expiration of a frame time of said oldest frame buffer.
