- * state of LZW decompressor
- *
- * small technical note
- * --------------------
- *
- * We use a few tricks in this implementation that are explained here to
- * ease debugging and maintenance.
- *
- * - First of all, the `prefix' and `suffix' arrays contain the suffix
- * and prefix for codes over 256; this means that
- *
- * prefix_of(code) == state->prefix[code-256]
- * suffix_of(code) == state->suffix[code-256]
- *
- * Each prefix is a 16-bit code, and each suffix an 8-bit byte.
- *
- * Both arrays are stored in a single memory block, pointed to by
- * `state->prefix'. This means that the following equality is always
- * true:
- *
- * state->suffix == (FT_Byte*)(state->prefix + state->prefix_size)
- *
- * Of course, state->prefix_size is the number of prefix/suffix slots
- * in the arrays, corresponding to codes 256..255+prefix_size.
- *
- * - `free_ent' is the index of the next free entry in the `prefix'
- * and `suffix' arrays. This means that the corresponding `next free
- * code' is really `256+free_ent'.
- *
- * Moreover, `max_free' is the maximum value that `free_ent' can reach.
- *
- * `max_free' corresponds to `(1 << max_bits) - 256'. Note that this
- * value is always <= 0xFF00, which means that both `free_ent' and
- * `max_free' can be stored in an FT_UInt variable, even on 16-bit
- * machines.
- *
- * If `free_ent == max_free', you cannot add new codes to the
- * prefix/suffix table.
- *
- * - `num_bits' is the current number of code bits, starting at 9 and
- * growing each time `free_ent' reaches the value of `free_bits'. The
- * latter is computed as follows
- *
- * if num_bits < max_bits:
- * free_bits = (1 << num_bits)-256
- * else:
- * free_bits = max_free + 1
- *
- * Since the value of `max_free + 1' can never be reached by
- * `free_ent', `num_bits' cannot grow larger than `max_bits'.
