Computes frequency-tuned saliency (Achanta et al., CVPR 2009): distance in CIELAB (D65) between each pixel of a 5×5 binomially smoothed copy and the image mean colour, on a copy with at most 400 px on the long side. For each ratio the largest crop of that ratio (full height or full width) is slid along the free axis; the position keeping the most saliency wins, ties go to the position nearest the saliency centroid.
