       The  following routines are used by the library to swap 16-, 32- and 64-bit data and to reverse the order
       of bits in bytes.

       TIFFSwabShort() and TIFFSwabLong() and TIFFSwabFloat() swap the bytes in a single 16-  and  32-bit  item,
       respectively.

       TIFFSwabLong8() and TIFFSwabDouble() swap the bytes in a single 64-bit item.

       TIFFSwabArrayOfTriples()  swap  the first and the third byte of each triple (three bytes) within the byte
       array. The second byte of each triple stays untouched.

       TIFFSwabArrayOfShort() and  TIFFSwabArrayOfLong(), TIFFSwabArrayOfFloat() swap the bytes in an  array  of
       16- and 32-bit items, respectively.

       TIFFSwabArrayOfLong8() and TIFFSwabArrayOfDouble() swap the bytes in an array of 64-bit items.

       TIFFReverseBits()  replaces  each  byte in data with the equivalent bit-reversed value. This operation is
       performed with a lookup table, which is returned using the TIFFGetBitRevTable() function.   The  reversed
       parameter  specifies which table should be returned. Supply 1 if you want bit reversal table. Supply 0 to
       get the table that do not reverse bit values. It is a lookup table that  can  be  used  as  an  "identity
       function"; i.e. TIFFNoBitRevTable[n] == n.

       None.
