+ Huffman code decoding is performed using a multi-level table lookup.
+ The fastest way to decode is to simply build a lookup table whose
+ size is determined by the longest code. However, the time it takes
+ to build this table can also be a factor if the data being decoded
+ is not very long. The most common codes are necessarily the
+ shortest codes, so those codes dominate the decoding time, and hence
+ the speed. The idea is you can have a shorter table that decodes the
+ shorter, more probable codes, and then point to subsidiary tables for
+ the longer codes. The time it costs to decode the longer codes is
+ then traded against the time it takes to make longer tables.
+
+ This results of this trade are in the variables lbits and dbits
+ below. lbits is the number of bits the first level table for literal/
+ length codes can decode in one step, and dbits is the same thing for
+ the distance codes. Subsequent tables are also less than or equal to
+ those sizes. These values may be adjusted either when all of the
+ codes are shorter than that, in which case the longest code length in
+ bits is used, or when the shortest code is *longer* than the requested
+ table size, in which case the length of the shortest code in bits is
+ used.
+
+ There are two different values for the two tables, since they code a
+ different number of possibilities each. The literal/length table
+ codes 286 possible values, or in a flat code, a little over eight
+ bits. The distance table codes 30 possible values, or a little less
+ than five bits, flat. The optimum values for speed end up being
+ about one bit more than those, so lbits is 8+1 and dbits is 5+1.
+ The optimum values may differ though from machine to machine, and
+ possibly even between compilers. Your mileage may vary.

+/* Macros for inflate() bit peeking and grabbing.
+ The usage is:
+
+ NEEDBITS(j)
+ x = b & mask_bits[j];
+ DUMPBITS(j)
+
+ where NEEDBITS makes sure that b has at least j bits in it, and
+ DUMPBITS removes the bits from b. The macros use the variable k
+ for the number of bits in b. Normally, b and k are register
+ variables for speed, and are initialized at the beginning of a
+ routine that uses these macros from a global bit buffer and count.
+
+ If we assume that EOB will be the longest code, then we will never
+ ask for bits with NEEDBITS that are beyond the end of the stream.
+ So, NEEDBITS should not read any more bytes than are needed to
+ meet the request. Then no bytes need to be "returned" to the buffer
+ at the end of the last block.
+
+ However, this assumption is not true for fixed blocks--the EOB code
+ is 7 bits, but the other literal/length codes can be 8 or 9 bits.
+ (The EOB code is shorter than other codes because fixed blocks are
+ generally short. So, while a block always has an EOB, many other
+ literal/length codes have a significantly lower probability of
+ showing up at all.) However, by making the first table have a
+ lookup of seven bits, the EOB code will be found in that first
+ lookup, and so will not require that too many bits be pulled from
+ the stream.
