  I use less accurate approximation here by simply left-shifting the input
  value and filling the low order bits with zeroes. This method improves PNG
  compression but this scheme cannot reproduce white exactly, since it does
  not generate an all-ones maximum value; the net effect is to darken the
  image slightly.

  The better method should be "left bit replication":

   4 3 2 1 0
   ---------
   1 1 0 1 1

   7 6 5 4 3  2 1 0
   ----------------
   1 1 0 1 1  1 1 0
   |=======|  |===|
       |      leftmost bits repeated to fill open bits
       |
   original bits
