d091b809b43510a6dcab09a0a28d20da366474ef Correlate od_compute_dist_8x8 with sum of squared error
Piecewise linear fit without activity masking on subset3 intra
and objective-1-fast inter, by simple linear regression.
In combination with 79c0f32c "Remove DCT from od_compute_dist_8x8",
this gives a even trade between perceptual and non-perceptual metrics.
