* LLDir::XUI (file lives under "xui" subtree), LLDir::TEXTURES (file
* lives under "textures" subtree), LLDir::SKINBASE (file lives at top

* @param filename Desired filename within subdir within skin, e.g.
* "panel_login.xml". DO NOT prepend (e.g.) "xui" or the desired language.
* @param constraint Callers perform two different kinds of processing.
* When fetching a XUI file, for instance, the existence of @a filename in
* the specified skin completely supercedes any @a filename in the default
* skin. For that case, leave the default @a constraint=CURRENT_SKIN. The
* returned vector will contain only
* ".../<i>current_skin</i>/xui/en/<i>filename</i>",
* ".../<i>current_skin</i>/xui/<i>current_language</i>/<i>filename</i>".
* But for (e.g.) "strings.xml", we want a given skin to be able to
* override only specific entries from the default skin. Any string not
* defined in the specified skin will be sought in the default skin. For
* that case, pass @a constraint=ALL_SKINS. The returned vector will
* contain at least ".../default/xui/en/strings.xml",
* ".../default/xui/<i>current_language</i>/strings.xml",
* ".../<i>current_skin</i>/xui/en/strings.xml",
