Tie distant fog feature to viewing distance by default
Distant fog feature, though effective and necessary for preserving the intended fog depth of different weathers, appears to be rarely used in practice - most likely because it is not exposed in launcher and needs manual adjusting in settings.cfg. Users also report their fog "breaking" after changing their view distance, unaware that distant fog needs manual readjustment to get the expected result with their changed view distance. A solution would be to tie it to viewing distance by default.
If necessary, there could still be a toggle to decouple it for those users/developers who prefer a esoteric fog setup (for instance, those wanting their viewing distance to continue well beyond max fog visibility).
