   5  // Each decodeTable is represented by an array of [2]int16's: a binary tree.
   6  // Each array element (other than element 0, which means invalid) is a branch
   7  // node in that tree. The root node is always element 1 (the second element).
   8  //
   9  // To walk the tree, look at the next bit in the bit stream, using it to select
  10  // the first or second element of the [2]int16. If that int16 is 0, we have an
  11  // invalid code. If it is positive, go to that branch node. If it is negative,
  12  // then we have a leaf node, whose value is the bitwise complement (the ^
  13  // operator) of that int16.
  14  //
  15  // Comments above each decodeTable also show the same structure visually. The
  16  // "b123" lines show the 123'rd branch node. The "=XXXXX" lines show an invalid
  17  // code. The "=v1234" lines show a leaf node with value 1234. When reading the
  18  // bit stream, a 0 or 1 bit means to go up or down, as you move left to right.
  19  //
  20  // For example, in modeDecodeTable, branch node b005 is three steps up from the
  21  // root node, meaning that we have already seen "000". If the next bit is "0"
  22  // then we move to branch node b006. Otherwise, the next bit is "1", and we
  23  // move to the leaf node v0000 (also known as the modePass constant). Indeed,
  24  // the bits that encode modePass are "0001".
  25  //
  26  // Tables 1, 2 and 3 come from the "ITU-T Recommendation T.6: FACSIMILE CODING
  27  // SCHEMES AND CODING CONTROL FUNCTIONS FOR GROUP 4 FACSIMILE APPARATUS"
