/*
  I use here less accurate approximation by simply
 left-shifting the input
  value and filling the low order bits with
 zeroes. This method improves png's
  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
       |
