Steve,

Thanks for the info.  I currently generate each layer of my 3-layer  
map using the --gmapsupp switch and then just combine the three  
gmapsupp.img files.  Given your notes, it seems that this may be  
wrong.  Instead I should only create the gmapsupp.img at the last  
step.  Am I wrong to create "intermediate" gmapsupp.img files and then  
combine them?
