+Same as \helpref{GetMimeType}{wxfiletypegetmimetype} but returns array of MIME
+types. This array will contain only one item in most cases but sometimes,
+notably under Unix with KDE, may contain more MIME types. This happens when
+one file extension is mapped to different MIME types by KDE, mailcap and
+mime.types.
