[Biojava-l] Multiple alignment display issues

[Russ Kepler]

Further in my efforts in using the FlexibleAlignment class in conjunction with 
the display the alignments I have created some test code, reproduced below.  
The sequences are all displaying, but not in the alignment range.  Am I 
simply missing something simple here, like a symbol renderer that handles a 
range?  Or should someone be rewriting the context before the renderer is 
called?  

(Apologies for the form - I've had to maintain this in a development 
environment to use my modified BioJava ).
