* Plumb bounding boxes through potential intersections
* Quick bbox reject for bins that can't possibly intersect
* Inching toward attribute accumulation in megatile handling

that have an explicit attribute accumulator set, because the order of
operations is too messy and weird

Rework the can-the-next-zoom-stop-early logic to avoid going
one zoom further than needed.
