  "message": "Write shorter matrix_coef_delta if possible\n\nI believe this optimization is the reason why the decoder reconstructs\nthe matrix coefficient by calculating (prev + delta + 256) % 256 rather\nthan the more obvious prev + delta. Take advantage of that, even though\ndelta is unlikely to be \u003c -128 or \u003e\u003d 128.\n",
