Thanks for the explanation. I had always been wondering what the  
difference was, between TrueType fonts provided as a single .dfont  
file (an OS X format, I guess) and TrueType fonts provided as a  
collection of .ttf files (a Windows format, I guess), other than a  
mere packaging difference, given OS X can use both. Now that makes  
more sense.
