Well, this is a basic question, but why don't I have to add -lpng12 to  
my test program if it is writing out PNG files? Is that somehow  
bundled into the macports version of libcairo.a?

You can do whatever you want with the Windows builds. I don't want to  
hold you back you from making Windows builds easier to  generate and  
use, but I am an MS nothing, and I can't support Windows code, so  
it'll have to be an opengrads feature. We haven't implemented anything  
in GrADS yet, but I don't see how we could close the door on the  
possibility of alternatives to X.

Yeah, I really don't care about that as long as X11 is supported in OS  
X.
