The panel had one distance for the view edges, the widgets it steps around, and the selection alike, so it stood eight pixels from a building and touched it outright along the top. The gap from the selection is now its own value, half a tile, and it is horizontal only -- the top edges stay level. It is sampled where the tile size is known, in the same moment as the anchor rectangle, and travels with it: a rectangle frozen in one moment has no meaningful distance to a tile size measured in another. chooseSide now takes the gap in place of the margin, the band having already taken the margin off.
