    Incorporates a speed feature for fast forward updates of
    coefficients. This feature takes 3 values:
    0 - use standard 2-loop version
    1 - use a 1-loop version
    2 - use a 1-loop version with reduced updates
    
    Results: derfraw300 +0.007% (on speed 0) at feature value = 1
                        -0.160% (on speed 0) at feature value = 2
    
    There is substantial speed up at speeds 2 and above for low
    resolution sequences where the entropy updates are a big part
    of the overall computations.
