Previously they appeared centered at the top of the page;
now we put them centered at the bottom, unless the `pagenumbering`
variable is set (this gives users full control over page
number format and position,

* Let the user choose type of PDF/A generated with ConTeXt (closes#5608)
* Updated ConTeXt test documents for changes in tagging
* Updated color profile settings in accordance with ConTeXt wiki
* Made ICC profile and output intent for PDF/A customizable
* Read pdfa variable from meta (and updated manual)
We can't always tell if it's LaTeX, ConTeXt, or plain TeX.
Better just to use "tex" always.
Also changed:
ConTeXt writer: now outputs raw "tex" blocks as well as "context".
(Closes#969).
RST writer: uses ".. raw:: latex" for "tex" content.
(RST doesn't support raw context anyway.)
Note that if "context" or "latex" specifically is desired,
you can still force that in a markdown document by using
the raw attribute (see MANUAL.txt):
```{=latex}
\foo
```
Note that this change may affect some filters, if they assume that raw
tex parsed by the Markdown reader will be RawBlock (Format "latex").
In most cases it should be trivial to modify the filters to accept
"tex" as well.
Fixes#2609.
This PR introduces the new-style section headings: `\section[my-header]{My Header}` -> `\section[title={My Header},reference={my-header}]`.
On top of this, the ConTeXt writer now supports the `--section-divs` option to write sections in the fenced style, with `\startsection` and `\stopsection`.
This is now the default for pandoc's Markdown.
It allows whitespace between the two parts of a
reference link: e.g.
[a] [b]
[b]: url
This is now forbidden by default.
Closes#2602.
