Defaults

Divisor used to derive the default spatial-hash cell size from the smaller of the x and y ranges: cellSize = min(xSize, ySize) / cellSizeDivisor. Tunes the trade-off between bucket count and per-bucket occupancy for within / nearest queries. Must be positive.

Multiplicative growth factor used by nearest when its initial guess radius doesn't return enough candidates and it expands the search. Must be strictly greater than 1.0; otherwise the radius never grows (or shrinks).
