* Import Affinity issue 1606 special shapes * Affinity corpus: give the #1606 sample ceilings a margin for font differences between machines The samples' labels render with whatever fonts are installed, so the measured differences move by up to 0.8 between machines; each ceiling is now the higher measurement plus about 1. Also use as_chunks in on_white (clippy with --features corpus).
