    Increased threshold(t) for interp filter search. This sped up the
    encoder with some PSNR loss.
    
    Borg tests were ran at speed 2.
    t = 100, PSNR loss:
    -0.710%(derf); -0.561%(stdhd); -0.647%(youtube)
    speedup:
    9%(derf); 3%(stdhd); 5.7%(youtube)
    
    t = 500, PSNR loss:
    -1.687%(derf); -1.665%(stdhd); -1.664%(youtube)
    speedup:
    18%(derf); 10%(stdhd); 8%(youtube)
