+   *
+   *  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'.
