Keeps stacked blocks supported when a thin terrain paints over them. Painting ground over a block replaces that block; if another block rests on it, the upper block would float, so the paint is refused. A block with nothing above it can still be painted over. Author it on the thin terrain's rule list; the stack itself is owned by TerrainStacking3D.
