Module notes 

Footnote and endnote content, laid out once before pagination.

Notes used to be laid out inside the post-pagination pass that drew them, which meant pagination could not know how much room they would need and drew body text straight over them. Laying them out here, ahead of pagination, lets the paginator reserve exactly the height it will later draw. Reserve and render read the same lines, so they cannot disagree.

The marker is shaped here too. The paginator only holds &FontManager and shaping needs &mut, so a note that arrives pre-shaped is a note the paginator can place without touching a font.
