40 * FIXME: Re-implement row painting using row elements.
42 * This is not difficult in principle, but the code is intricate and
43 * needs some careful analysis. The first thing that needs to be done
44 * is to break row elements with the same criteria. Currently breakRow
45 * does not consider on-the-fly spell-checking, but it is not clear to
46 * me that it is required. Moreover, this thing would only work if we
47 * are sure that the Row object is up-to-date when drawing happens.
48 * This depends on the update machinery.
50 * This would allow to get rid of the Bidi class.
55 * A class used for painting an individual row of text.
56 * FIXME: get rid of that class.
