Fix author information.
2000-05-04 Christopher James Lahey <clahey@helixcode.com> * e-cell-text.c, e-cell-text.h: Fix author information. * e-table-group-leaf.c: Set a length threshold of 200. * e-table-item.c: Height cache is now actually a map. Made "length_threshold" argument work. If over the length threshold, use the height cache to get a better estimate so that once the height cache is full, height estimate is perfect. svn path=/trunk/; revision=2791
