This is a fast test which essentially does bounding-box overlap given a worst-case clearance.

It's used when looking up the specific item-to-item clearance might be expensive and should be deferred till we know we have a possible hit.

This one is for tessellated items.

(All shapes in the tree will be from a single BOARD_ITEM.) It checks all items in the bbox overlap to find the minimal actual distance and position.
