+ * g_themed_icon_update_names:
+ * @themed: a #GThemedIcon.
+ *
+ * Update the actual icon name list, based on the requested names (from
+ * construction, or later added with g_themed_icon_prepend_name() and
+ * g_themed_icon_append_name()).
+ * The order of the list matters, indicating priority:
+ * - The first requested icon is first in priority.
+ * - If "use-default-fallbacks" is #TRUE, then it is followed by all its
+ * fallbacks (starting from top to lower context levels).
+ * - Then next requested icons, and optionally their fallbacks, follow.
+ * - Finally all the style variants (symbolic or regular, opposite to whatever
+ * is the requested style) follow in the same order.
+ *
+ * An icon is not added twice in the list if it was previously added.
+ *
+ * For instance, if requested names are:
+ * [ "some-icon-symbolic", "some-other-icon" ]
+ * and use-default-fallbacks is TRUE, the final name list shall be:
+ * [ "some-icon-symbolic", "some-symbolic", "some-other-icon",
+ * "some-other", "some", "some-icon", "some-other-icon-symbolic",
+ * "some-other-symbolic" ]
+ *
+ * Returns: (transfer full) (type GThemedIcon): a new #GThemedIcon
