- The latest volley in the FlightGear lighting wars.

- Ambient is based off the lookup table only.
- Diffuse is based off of the lookup table, but multiplied by a combination
  of sun/fog colors.

The result is a bit more ambient light at dusk and night since the world is
never 100% dark.  And we still get nice sunset/sunrise colored illumination
of surfaces that are directly illuminated by the sun.
