Height modifiers that carve the rivers into a world: path modifiers along each river with
descending bed heights. Add them with world.addModifier(m) (or world.set({ modifiers })). Pass
the frame the heights were sampled in; on a planet, points are projected onto the sphere and
heights converted to elevations, as the world expects.
