33/* Here is how the buffer works internally: -
34 * -
35 * There are two string pointers: in_string and out_string. They -
36 * always have same allocated size, but different length and positions. -
37 * -
38 * As an optimization, both in_string and out_string may point to the -
39 * same piece of memory, which is owned by in_string. This remains the -
40 * case as long as: -
41 * -
42 * - copy_glyph() is called -
43 * - replace_glyph() is called with inplace=TRUE -
44 * - add_output_glyph() and add_output_glyphs() are not called -
45 * -
46 * In that case swap(), and copy_glyph(), and replace_glyph() are all -
47 * mostly no-op. -
48 * -
49 * As soon an add_output_glyph[s]() or replace_glyph() with inplace=FALSE is -
50 * called, out_string is moved over to an alternate buffer (alt_string), and -
51 * its current contents (out_length entries) are copied to the alt buffer. -
52 * This should all remain transparent to the user. swap() then switches -
53 * in_string and alt_string. alt_string is not allocated until its needed, -
54 * but after that it's grown with in_string unconditionally. -
55 * -
56 * The buffer->separate_out boolean keeps status of whether out_string points -
57 * to in_string (FALSE) or alt_string (TRUE). -
