 =========================================
 
 Note: The new renderers and dmabuf support are using graphics drivers
 in different ways than the old gl renderer, and trigger new driver bugs,
 (see for example https://gitlab.gnome.org/GNOME/gtk/-/issues/6418 and
 https://gitlab.gnome.org/GNOME/gtk/-/issues/6388). Therefore, it is
-recommended to use the latest mesa release (24.0) with the new renderers.

 /* The format of the generated data is: a(aussasasu).
  * Each member of the array has the following fields:
- * au - sequence of unicode codepoints. If the
- *      sequence contains a 0, it marks the point
- *      where skin tone modifiers should be inserted
+ * au - sequence of unicode codepoints, including the emoji presentation
+ *      selector (FE0F) where necessary. skin tone variations are represented
+ *      with either the first tone code point (1F3FB) or 0. the choice indicates
+ *      the handling of the generic sequence (i.e., no tone), which may have a
+ *      default text presentation and thus require the emoji presentation
+ *      selector (unlike sequences with a tone, which are always presented as
+ *      emojis). 0 indicates the text case, that is, replace this code point
+ *      with FE0F, while 1F3FB indicates this code point should be omitted.
  * s  - name in english, e.g. "man worker"
  * s  - name in locale
  * as - keywords in english, e.g. "man", "worker"
