* coding reads a block's values with, and the thresholds the smoothing
* of block edges works to.
*
* The numbers are the ones the standard publishes in its tables 7-3,
* 7-4, 8-14 to 8-17, 9-4 to 9-10, 9-12 to 9-33, 9-44 and 9-45. They were
* copied from published tabulations and checked against values the
* standard fixes elsewhere; the decoding that reads them is original.
*
* HEVC reads some of the same tables, since the two formats share the
* arithmetic coding.
