Line layouts are lists than may contain the following tuples: * (column width of text segment, start offset, end offset) * (number of space characters to insert, offset or None) * (column width of insert text, offset, "insert text") The offset in the last two tuples is used to determine the attribute used for the inserted spaces or text respectively. The attribute used will be the same as the attribute at that text offset. If the offset is None when inserting spaces then no attribute will be used. zVThis function must be overridden by a real text layout class.
