Fix #4129. Fix #4168. Html Writer, which all the Pdf writers use, defines its charts and drawings (henceforth I will just use charts for this discussion) using position:absolute and z-index. Browsers handle this correctly, but none of the Pdf writers do, and I can't think of an alternative method of styling them. The result is that the charts take up too much or too little room on the Pdf. I suggested in the two discussions that treating the areas covered by the charts as merged cells might mitigate the problem. I think there are too many unknowns to do so automatically (and see next paragraph). However, adding to Spreadsheet new methods `mergeChartCellsForPdf` and `mergeDrawingCellsForPdf` allows the end user to do this if desired. The new methods are exercised for charts in samples/Chart/32_Chart_read_write_PDF, the results of which are much improved as a result. New samples/Pdf/21f_Drawing_mpdf does likewise for drawings. The new methods alter the spreadsheet they are working on, which could be a problem if you still wish to work with the spreadsheet after writing it to Pdf. In that case, making a copy of the spreadsheet, then calling the new methods on the copy, and writing the copy to Pdf is probably best.
