This experiment biases the rd decision based on the impact a mode decision has on the relative spatial complexity of the reconstruction vs the source. The aim is to better retain a semblance of texture even if it is slightly misaligned / wrong, rather than use a simple rd measure that tends to favor use of a flat predictor if a perfect match can't be found. This improves the appearance of texture and visual quality on specific test clips but is hidden under a flag and currently off by default pending visual quality testing on a wider Yt set.
