  "message": "Redo the forward 4x4 dct\n\nThe new fdct lowers the round trip sum squared error for a\n4x4 block ~0.12. or ~0.008/pixel. For reference, the old\nmatrix multiply version has average round trip error 1.46\nfor a 4x4 block.\n\nThanks to \"derf\" for his suggestions and references.\n\nChange-Id: I5559d1e81d333b319404ab16b336b739f87afc79\n",
