sources/titleblock/ is ~8,300 lines and the format was undocumented:
title blocks were mentioned in features and user_manual, but nothing said
how to author one.
Covers the grid model and the part that makes a template fit any paper
size -- the three kinds of column length, where an unprefixed value is
absolute pixels, t22% is a fraction of the total width and r100% takes
the remainder, while rows are always absolute. Also label-vs-value and
why only labels are normally translated, the more permissive variable
substitution used here (both %{name} and %name, longest key first, but
only the braced form is discoverable by the editor), the two logo storage
forms and the fact that bitmaps are forced to base64, the four collections
including the embedded one that makes a project self-contained, and the
cell tag names.
Notes F023 inline as a known defect: a logo whose storage attribute is
neither xml nor base64 is written back with no image data.
