// The orders_* tables encode the order in which we visit blocks of the given
// size. For example, orders_32x32 has (128/32)^2 = 4^2 = 16 entries that
// correspond to the 32x32 blocks in a 128x128 superblock (in raster order). If
// an entry at position i is less than the entry at position j, that means that
// the block at position i is visited before that at position j if the
// superblock is divided by repeated PARTITION_SPLITs down to 32x32 blocks.
//
// The other tables are similar. Those for non-square block sizes assume that
// the superblock was partition with PARTITION_SPLIT until the square block size
// with the larger of their dimensions, then there was a horizontal or vertical
// partition to generate their size. For example, the orders_16x32 table assumes
// that the superblock was divided by PARTITION_SPLIT down to 32x32 blocks, then
// each was partitioned by a PARTITION_VERT into two 16x32 blocks.
//
// These tables can be used to calculate whether one block has been decoded
// before another. Since PARTITION_SPLIT is the only recursive partitioning
// operation, it doesn't actually matter whether the other block is the same
// size as the current one: comparing entries in the table will still correctly
// answer the question "has the other one been decode already?".
//
// Also note that this works correctly for the mixed horizontal partitions
// (PARTITION_HORZ_A and PARTITION_HORZ_B): if you look up the smaller square
// block size, the rectangle will be treated as two blocks that are decoded
// consecutively (before or after this block). If you look up the rectangle, the
// two squares will be treated as a single rectangle and, again, they were
// decoded together before or after this block.
