Thanks for the nice explanation!

Because nothing important happens in the “...”?

Okay, I would like that.

Correct.  I think anything drawn before drawMapWater/drawMapTerrain
will not show up at all, because they are drawn without any
transparency.  Right?

What do you mean by “cover”?  Because buildings and resources are
drawn first, they can not cover areas, but areas can cover them.

Anyway, the area marks move around because the areas are animated.

By the way, I notice that overlay maps are drawn after globules.  I'd
much rather they were drawn before, because I find it extremely hard
to _see_ globules under them and it makes the overlay maps mostly not
useful to me.  (Of course, I also would not like the overlay maps to
be affected by fog of war, because the meaning of the overlay maps is
determined by their intensity and the fog of war would interfere with
that.  I don't know how to accomplish both.)
