Actually, I ended up using the adjacent terrain stuff to generate the
climates in the first place (you may notice a terrain-type called "land"
that never appears on the map).  Although a more sophisticated
terrain-generating algorithm is still needed in order to lay out
climates in a way that's even remotely realistic.

I'll give it a try, though.

Agreed.  Probably the best way to re-write it would be to have actual
tables to control how coatings appear due to temperature, such as:

tt_temperature-min-to-coat
tt_temperature-max-to-coat

Maybe also an interpolation list so that one could actually apply
different thicknesses to the coating, as well.


This would solve the mud/snow problem in a way that would work for both
omniterr.g and ww2-eur-42.g (although ww2-eur-42.g would need to have
the tables added to it).  It still wouldn't allow me to make the
presence or absence of coatings affected by other properties (e.g. in
extremely arid climates, it almost never snows, regardless of
temperature, because the precipitation just isn't there), but it would
be a step in the right direction.

On the other hand, as I think back to the way the colors turned out in
the terrain module, it may look even worse if all of the coatings are
drawn.

While this bug does need to be (eventually) addressed, I think I'll have
to improve the graphics before then, so that I never have to find out
how it looks with all of the coatings in place.
