In 6.9.3, "fog", it says

for height larger than than Fog_Offset is calculated by:
1/(1 + (y - Fog_Offset) / Fog_Alt) ^2)

There are two opening parenthesis and three closing parenthesis in that
expression. Perhaps the last parenthesi shouldn't be there? I'm not sure if
it's supposed to be

1/(1 + ((y - Fog_Offset) / Fog_Alt) ^2)
or
1/(1 + (y - Fog_Offset) / Fog_Alt) ^2

I assume it's the former, since that has a derivative of zero with respect
to y at y=Fog_Offset.
