Orkuncakilkaya b9f9cb8495 render3d: r3d_fog_wall(dist) - fog that closes to the sky's horizon colour from 0.3 dist to dist, and nothing drawn past dist + 8 m ...

Every lit program blends toward the horizon colour (the prefiltered sky with the sun's inscatter,
so it carries the day's grade); the sky's horizon band is pulled to the same colour, wider the
closer the wall. The far plane, scatter and stream cull reach and the shadow cascades are clamped
to the wall; the reflection pass shares the shaders and the cull. 0 is off: every branch is gated
on u_fog_wall > 0 and r3d_reach hands back the far it was given. R3D_FOG_WALL=<m> for a shot.
