render3d: the fog wall is solid by 0.85 of it and the blades end at 0.75

Browse source 
Whatever is cut at the wall is now cut inside full fog: at 0.3-1.0 the last metres before the cut
were 80-95% fogged against fully fogged ground behind, which drew a line of tufts at 70 m and a
dark band of blade tips at 30 m. The blades thin out while the fog is still coming in.
