I suppose longest could be generated first, but I recall at the time I 
set up the code, it generally looked better to prioritize by largest 
first, otherwise taxiways would clip into tie down areas and [IMO] 
looked less nice.  Ultimately it might be nice to let the airport 
designer specify the layering, but without that information, we just 
have to make our best attempt in the code.

I would imagine a day sometime in the future where the designer would 
lay out all the taxiways and corners and lines and specify all of the 
elements explicitely so that terragear isn't left to guess.

Curt.
