ME haze = fog visibility setting more than 19685 ft

[HILOK]

starting this topic as a follow-up to the threads below, because i hope it could be an easy solution to those too.

statement
most of the time there is enough moisture in the air to make landscape colors appear faint from high altitudes, although horizontal visibilities on ground are good (>10km). this is called haze.

problem
currently the ME limits fog>visibility settings to about 20000ft / 6km.

solution
hopefully could simply consist in enabling fog visibilities of more than 19685 ft. this would not only allow to make the maps appear as if there was haze, but also fill the gap for visibilities between 6000m and "unlimited", which is also highly needed
