_TIFFClampDoubleToUInt32() clamps double values into the range of uint32_t (i.e. 0 .. 0xFFFFFFFF)

       _TIFFMultiply32()  and  _TIFFMultiply64() checks for an integer overflow of the multiplication result and
       return the multiplication result or 0 if an overflow would happen.  The string where is  printed  in  the
       error message in case an overflow happens and can be used to indicate where the function was called.
