Implement max_width_by_row.
2002-01-21 Christopher James Lahey <clahey@ximian.com> * e-cell-text.c: Implement max_width_by_row. * e-cell-tree.c: Use max_width_by_row in max_width function. * e-cell.c, e-cell.h (e_cell_max_width_by_row): Added this new method to ECell. svn path=/trunk/; revision=15418
