Tweak FogVolume density property to allow sliding to negative values
Tweak FogVolume density property to allow sliding to negative values

Negative density is used to subtract fog from the rest of the world.

The visible range in the slider was reduced to [-8; 8] as FogVolume
density should generally not exceed 8.0 (it can introduce aliasing).
