+It's an example for LZMA + x86 Filter use.
+You can use .lzma86 extension, if you write that stream to file.
+.lzma86 header adds one additional byte to standard .lzma header.

+ 2 4 dictSize (little endian)

+
+
+Lzma86_Encode
+-------------
+level - compression level: 0 <= level <= 9, the default value for "level" is 5.
+
+dictSize - The dictionary size in bytes. The maximum value is
+ 128 MB = (1 << 27) bytes for 32-bit version
+ 1 GB = (1 << 30) bytes for 64-bit version
+ The default value is 16 MB = (1 << 24) bytes, for level = 5.
+ It's recommended to use the dictionary that is larger than 4 KB and
+ that can be calculated as (1 << N) or (3 << N) sizes.
+ For better compression ratio dictSize must be >= inSize.
+
+filterMode:
+ SZ_FILTER_NO - no Filter
+ SZ_FILTER_YES - x86 Filter
+ SZ_FILTER_AUTO - it tries both alternatives to select best.
+ Encoder will use 2 or 3 passes:
+ 2 passes when FILTER_NO provides better compression.
+ 3 passes when FILTER_YES provides better compression.
+
+Lzma86Encode allocates Data with MyAlloc functions.
+RAM Requirements for compressing:
+ RamSize = dictionarySize * 11.5 + 6MB + FilterBlockSize
+ filterMode FilterBlockSize
+ SZ_FILTER_NO 0
+ SZ_FILTER_YES inSize
+ SZ_FILTER_AUTO inSize

+
+dictSize - The dictionary size in bytes. The maximum value is
+ 128 MB = (1 << 27) bytes for 32-bit version
+ 1 GB = (1 << 30) bytes for 64-bit version
+ The default value is 16 MB = (1 << 24) bytes.
+ It's recommended to use the dictionary that is larger than 4 KB and
+ that can be calculated as (1 << N) or (3 << N) sizes.
+
+lc - The number of literal context bits (high bits of previous literal).
+ It can be in the range from 0 to 8. The default value is 3.
+ Sometimes lc=4 gives the gain for big files.
+
+lp - The number of literal pos bits (low bits of current position for literals).
+ It can be in the range from 0 to 4. The default value is 0.
+ The lp switch is intended for periodical data when the period is equal to 2^lp.
+ For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's
+ better to set lc=0, if you change lp switch.
+
+pb - The number of pos bits (low bits of current position).
+ It can be in the range from 0 to 4. The default value is 2.
+ The pb switch is intended for periodical data when the period is equal 2^pb.
+
+fb - Word size (the number of fast bytes).
+ It can be in the range from 5 to 273. The default value is 32.
+ Usually, a big number gives a little bit better compression ratio and
+ slower compression process.
+
+numThreads - The number of thereads. 1 or 2. The default value is 2.
+ Fast mode (algo = 0) can use only 1 thread.
