A local redraw keeps the narrower guarantee its parent holds when the new
drawing covers it, so widening and narrowing back do not churn the parent.
It checked that guarantee against `placement`, where the answer put the
drawing, rather than `region`, the box the drawing was made in and the box
both contracts are about. The two differ on every axis a widget reported
less than it was offered, so any such widget escalated to its parent every
time its contract widened -- which is the churn the retention exists to
avoid. `resize` and `try_reuse` both already ask about `region`.
