- main already rebuilt an edited table's block; the PR added a second
loop after it that could never fire. Formula refresh and the block
cache bump now live in the one loop.
- Formula refresh copies the drawing only for a table that has a field.
- A field cell lays its text out once and boxes it from those cells.
- A zero text height at one level falls through to the next instead of
ending the lookup.
- Field box constants and BACKGROUND keep their own doc comments.
