But if your fog changes frequently or suddenly, that change happens
asynchronously in all channels - which looks terrible. (This
may have been fixed recently - but this statement was certainly
true a year or so ago).
Doing the fog change in DRAW fixes *that* problem - but admittedly
you have to be careful not to try to change it anywhere else
as well.
