/**
 * Defines display objects.
 * <p>
 * These are capable of:
 * <ul>
 * <li>Being positioned by being dragged around on the screen. (See
 * {@link #setPositionable})
 * <li>Being hidden. (See {@link #setHidden})
 * <li>Controlling the layout. (See {@link #setControlling})
 * </ul><p>
 * These are manipulated externally, for example by a subclass of
 * {@link Editor}. They are generally not stored directly as part of the state
 * of the object, though they could be, but as part of the state of the external
 * control.
 * <p>
 * Instead of the usual MouseEvent handling methods, e.g mouseClicked(...),
 * Positionables have similar methods called doMouseClicked invoked by the
 * {@link Editor} subclass that contains them, so the Editor can handle e.g. box
 * selection, etc.
