Add\nnew contexts for these borders so they don\u0027t distort the probabilities of\nthe interior of the image where all partitions are legal.\n\nOnly include one context for each block size of each border direction\nbecause so few blocks fall into these contexts to begin with.\n\nobjective-1-fast:\n   PSNR | PSNR Cb | PSNR Cr | PSNR HVS |    SSIM | MS SSIM | CIEDE 2000\n-0.0294 | -0.0911 | -0.2382 |  -0.0481 | -0.0441 | -0.0450 |    -0.0454\n\nderf144: -0.135\nlowres: -0.124\nmidres: -0.076\nhdres: -0.078\n\nChange-Id: I909b98eebb7e49273cde90154c8408febe334158\n",
