  "message": "Palette: Don\u0027t use top-right pixel for context of color indices.\n\nThis reduces the complexity in a number of ways:\n- We need just 3 neighbors instead of 4.\n- Possible contexts reduce from 16 to 5.\n- On hardware side, getting the contexts for a whole block will be more\nparallelizable.\n\nAt the same time, compression performance improves very slightly:\n- Screen-content set (videos) (Google): BDRate improved by 0.32\n- screenshots set (images) (AWCY): PSNR improved by 0.62:\nhttps://arewecompressedyet.com/?job\u003dpalette_withTR2%402017-01-27T21%3A30%3A28.890Z\u0026job\u003dpalette_noTR2%402017-01-27T21%3A41%3A34.312Z\n\nChange-Id: Ie84ca32f05d55ad481a51c2d3abc579468597189\n",
