Two endpoints rather than a box: no text, no fill, and the diagonal of the frame with `flipV` picking which one. The three kinds share their preset names, since the heads a file declares are what tell them apart. ODF gives a line its own element and its heads a named marker, which needs the draw: prefix declared in styles.xml — undeclared, the file does not parse at all. Word keeps the frame and flips it.
