'DS (coded dictionary size, 1 byte)'
- Lzip divides the distance between any two powers of 2 into 8
- equally spaced intervals, named "wedges". The dictionary size is
- calculated by taking a power of 2 (the base size) and substracting
- from it a number of wedges between 0 and 7. The size of a wedge is
- (base_size / 16).
+ The dictionary size is calculated by taking a power of 2 (the base
+ size) and substracting from it a fraction between 0/16 and 7/16 of
+ the base size.
Bits 4-0 contain the base 2 logarithm of the base size (12 to 29).
- Bits 7-5 contain the number of wedges (0 to 7) to substract from
- the base size to obtain the dictionary size.
+ Bits 7-5 contain the numerator of the fraction (0 to 7) to
+ substract from the base size to obtain the dictionary size.
Example: 0xD3 = 2^19 - 6 * 2^15 = 512 KiB - 6 * 32 KiB = 320 KiB
