                Just a quick note on some of the unknown records:
            </p>
            <ul>
                <li>EC: MSODRAWING - A Microsoft drawing record. (Need to
                track down where this is documented).</li>
                <li>5D: OBJ: Description of a drawing object. (This is going to
                be a PITA to implement).</li>
                <li>33: Not documented. :-(</li>
                <li>105f: Not documented.  :-(</li>
                <li>104f: POS: Position record (should be able to safely leave this out).</li>
                <li>1022: CHARTFORMATLINK: Can be left out.</li>
            </ul>
            <p>
                It is currently suspected that many of those records could be
                left out when generating a bar chart from scratch.  The way
                we will be proceeding with this is to write code that generates
                most of these records and then start removing them to see
                how this effects the chart in excel.
