-/* Here is how the buffer works internally:
- *
- * There are two string pointers: in_string and out_string.  They
- * always have same allocated size, but different length and positions.
- *
- * As an optimization, both in_string and out_string may point to the
- * same piece of memory, which is owned by in_string.  This remains the
- * case as long as:
- *
- *   - copy_glyph() is called
- *   - replace_glyph() is called with inplace=TRUE
- *   - add_output_glyph() and add_output_glyphs() are not called
- *
- * In that case swap(), and copy_glyph(), and replace_glyph() are all
- * mostly no-op.
- *
- * As soon an add_output_glyph[s]() or replace_glyph() with inplace=FALSE is
- * called, out_string is moved over to an alternate buffer (alt_string), and
- * its current contents (out_length entries) are copied to the alt buffer.
- * This should all remain transparent to the user.  swap() then switches
- * in_string and alt_string.  alt_string is not allocated until its needed,
- * but after that it's grown with in_string unconditionally.
- *
- * The buffer->separate_out boolean keeps status of whether out_string points
- * to in_string (FALSE) or alt_string (TRUE).
