  Modified files:
    lib/Image            png.php 
  Log:
  Bit of optimization.
  FWIW:
  $iMax = strlen($input);
  for ($i = 0; $i < $iMax; $i++) {
  $t = ord($input[$i]);
  }
  Is faster then:
  $iMax = strlen($input) + 1;
  $input = unpack('C*', $input
  for ($i = 1; $i < $iMax; $i++) {
  $t = ord($input[$i]);
  }
  
  Ie ord() on a string index is quicker then unkacking the string and getting array indexes.
