terrain_ground

The ground a landscape paints by where it stands: four bands of colour climbing with altitude, a cliff over steep faces, a noise breaking each band's edge, and a slow macro variation across large patches (zero_terrain_ground_bands). terrainBlend paints all of its ground this way, and terrainSplat paints the share of a pixel no named layer claims this way (ground_fill), so a streamed landscape that draws one tile through each shows no seam between them.
