/**
* 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
