write_payslip.py

"""Writes a monthly payslip: a letterhead, the employee it names, an earnings table,
a dense table of contributions, and the cumulative figures a payslip carries.

The Python twin of the `write_payslip` example in Rust. The document is a table
before it is anything else: every contribution line is a base, a rate for the
employee and a rate for the employer, and the amount each rate comes to; the section
headings are rows that span the whole grid; and the totals are boxed off it. Every
figure on the page is worked out from the earnings above it, so the sums can be
checked with a pencil.

The file says what the page is made of, not only what it looks like: here is the
title, here is the table of the month's lines, here are its column headings and the
line each figure stands on. Each figure is tied to its line heading and its column
heading, the two a program reading the page aloud is given to announce it by. The mark
says in words what it shows, and the rules drawn across the page are marked as layout,
outside what the page says. The document claims PDF/UA-1.

Every word the page draws is held in `Words`, once per language, and `HQF_PDF_LANG`
picks which one is drawn. The figures, the rates, the ceiling and the employee's name
and staff number are the same in both.
