Various improvements to PDF export

> The PDF is 4 MB. I made a table of defective pages to accompany the PDF.
> I believe you should see the wiki markup of the pages in the CosmoCom
> Confluence site to understand the problems.

> Pages Problem
> All Pages are produced in A4 size. Need letter size for American
> market.
> 7-19 Indented link entries in Table of Contents (manually generated)
> appear in separate boxes.
> 25-30 Table columns are of equal size. In Confluence the sizes are
> unequal because the columns fit the contents - this is how they should
> appear in the PDF. Long text strings overlap table boundaries. Code
> text overlaps code macro boundaries (used indent macros).
> 62-68 There is a pseudo table effect: Items in code macros are
> boxed. Text items look like table cells printed only the right half of
> each cell.
> 75-78 Text strings extend beyond table and page boundaries. Text
> string extends beyond code macro.
> 88 See Conf-7175.
> 89 Long string overruns page boundary.
> 108-109 Right side boundary of code macro coincides with right side
> boundary of important note. (In confluence the code is entirely and
> symmetrically enclosed in the note.)
> 225-226 The table is illegible. Column two text overlaps column
> three text.
> 289-291 Code text overlaps right side boundary.
> 292-294 Text following the CIF and QCIF headings should not be in
> boxes. There is an XML problem on page 293: an extra bullet appears.
> 328-329 Table row is split across pages.
> 368 XML problem: two extra bullets appear.
> 405-406 Bulleted text in table appears in boxes.
> 489 The footnote looks like a row of a two column table.
