summer is the reference the whole palette is applied relative to — pass
the surface's own as-authored green (a scatter material's color, the pack's
grassland color) and midsummer comes out untouched. See FOLIAGE_GLSL.

differ from a plant's: the terrain shader turns straw rather than rust,
because ground cover does not do what a canopy does.
