-        chunk, after each 32 KB of uncompressed data is represented in the output compressed bitstream, the
-        output bitstream is padded with up to 15 bits of zeros to realign the bitstream on a 16-bit boundary
-        (even byte boundary) for the next 32 KB of data. This results in a compressed chunk of a byte-aligned
-        size. The compressed chunk could be smaller than 32 KB or larger than 32 KB if the data is
-        incompressible when the chunk is not the last one.
-
-        The LZXD engine encodes a compressed, chunk-size prefix field preceding each compressed chunk in
-        the compressed byte stream. The compressed, chunk-size prefix field is a byte aligned, little-endian,
-        16-bit field. The chunk prefix chain could be followed in the compressed stream without
-        decompressing any data. The next chunk prefix is at a location computed by the absolute byte offset
-        location of this chunk prefix plus 2 (for the size of the chunk-size prefix field) plus the current chunk
-        size.
-
-        2.2.2 E8 Call Translation
-
-        E8 call translation is an optional feature that can be used when the data to compress contains x86
-        instruction sequences. E8 translation operates as a preprocessing stage before compressing each
-        chunk, and the compressed stream header contains a bit that indicates whether the decoder shall
-        reverse the translation as a postprocessing step after decompressing each chunk.
-
-        The x86 instruction beginning with a byte value of 0xE8 is followed by a 32-bit, little-endian relative
-        displacement to the call target. When E8 call translation is enabled, the following preprocessing steps
-        are performed on the uncompressed input before compression (assuming little-endian byte ordering):
-
-        Let chunk_offset refer to the total number of uncompressed bytes preceding this chunk.
-
-        Let E8_file_size refer to the caller-specified value given to the compressor or decoded from the header
-        of the compressed stream during decompression.
-
-        The following example shows how E8 translation is performed for each 32-KB chunk of uncompressed
-        data (or less than 32 KB if last chunk to compress).
-
-            if (( chunk_offset < 0x40000000 ) && ( chunk_size > 10 ))
-                for ( i = 0; i < (chunk_size – 10); i++ )
-                    if ( chunk_byte[ i ] == 0xE8 )
-                        long current_pointer = chunk_offset + i;
-                        long displacement = chunk_byte[ i+1 ] |
-                        chunk_byte[ i+2 ] << 8 |
-                        chunk_byte[ i+3 ] << 16 |
-                        chunk_byte[ i+4 ] << 24;
-                        long target = current_pointer + displacement;
-                        if (( target >= 0 ) && ( target < E8_file_size+current_pointer))
-                            if ( target >= E8_file_size )
-                                target = displacement – E8_file_size;
-                            endif
-                            chunk_byte[ i+1 ] = (byte)( target );
-                            chunk_byte[ i+2 ] = (byte)( target >> 8 );
-                            chunk_byte[ i+3 ] = (byte)( target >> 16 );
-                            chunk_byte[ i+4 ] = (byte)( target >> 24 );
-                        endif
-                        i += 4;
-                    endif
-                endfor
-            endif
-
-        After decompression, the E8 scanning algorithm is the same. The following example shows how E8
-        translation reversal is performed.
-
-        long value = chunk_byte[ i+1 ] |
-        chunk_byte[ i+2 ] << 8 |
-        chunk_byte[ i+3 ] << 16 |
-        chunk_byte[ i+4 ] << 24;
-        if (( value >= -current_pointer ) && ( value < E8_file_size ))
-            if ( value >= 0 )
-                displacement = value – current_pointer;
-            else
-                displacement = value + E8_file_size;
-            endif
-            chunk_byte[ i+1 ] = (byte)( displacement );
-            chunk_byte[ i+2 ] = (byte)( displacement >> 8 );
-            chunk_byte[ i+3 ] = (byte)( displacement >> 16 );
-            chunk_byte[ i+4 ] = (byte)( displacement >> 24 );
-        endif
-
-        The first bit in the first chunk in the LZXD bitstream (following the 2-byte, chunk-size prefix described
-        in section 2.2.1) indicates the presence or absence of two 16-bit fields immediately following the
-        single bit. If the bit is set, E8 translation is enabled for all the following chunks in the stream using the
-        32-bit value derived from the two 16-bit fields as the E8_file_size provided to the compressor when E8
-        translation was enabled. Note that E8_file_size is completely independent of the length of the
-        uncompressed data. E8 call translation is disabled after the 32,768th chunk (after 1 gigabyte (GB) of
-        uncompressed data).
