[Therion] Multiple layers of overlayed maps

[Bill Gee]

Hi Stacho - Thanks for the tip.  I took a look at the sample you mention.  I 
was able to get the third segment outline to appear on the second segment map, 
as I wanted.  However, that outline also appears on the main map!

I tried it with both "below" and "above".  Same result both ways.  For this 
map, the complexity is such that the "above" display is less confusing than 
"below".

The MainPassage map contains the lowest level of the maze.  That makes sense 
since the rest of the cave is reached from there.  The middle level of the 
maze is in UpperMaze and the highest level is in UpperMaze2.

Note that the overlays for SinkholeEntrance and ESurveySidePassage only have 
one layer.  They display as I want them to, 

Below is my revised .th file ...

Thanks - Bill Gee
