  As I think about this, I believe the main use of overlays was the weather code 
- so that when it put snow effects, etc, it could know what objects were 
original to the map (eg, the base mountain) and which objects were put on top by 
weather effects.

  I believe the reason for this is so that the base map (say the scorn town) 
could reset, but the weather effects would persist across that reset.

  I don´t think anything is using the weather code - I´m not even sure to what 
extent it still works.
