That third argument you mentioned in the zone polygon definition is the 
end of polygon marker, correct? I see we have a shortcoming in the 
specctra export. I need to add a DSN "window" for the polygons which 
are holes. (PLANE .... (WINDOW....)) where the windows are part of a 
PLANE. But I see you are using the flag to mean an adjacent polygon, 
not a hole. And that the graphics stuff magically figures this out. 
Well I am not that smart.

I need to have Jean-Pierre or somebody tell me how to determine if a 
polygon within a zone container is a hole or a an adjacent polygon. 

Speaking about the BRD file format now:
If it is our intention to support both, then I think that there should 
be a start of polygon marker, not an end of polygon marker, and that the 
marker should say whether it is a hole or an adjacent polygon. I think 
we may have botched the board file format for ZONE_CONTAINERS.

I have no easy way to export to DSN both of the polygon types, both 
yours Tim and the holes.

Jean-Pierre, do you fully understand the problem? Looking at the 
grammar for (PLANE) clarifies the problem somewhat.

Yes, they are fascinating.
