So, what's this?

I didn't even know cairo had an --enable-pdf switch. I only use cairo  
for graphviz, and one of the features graphviz gains by using cairo  
is the ability to output pdfs. This has always worked for me, though  
I've never used --enable-pdf. So does --enable-pdf get us anything  
extra? I see from ./configure --help that the default for this option  
is "auto" so maybe for me it was automatically on and for you it was  
automatically off? I wonder what influences this automation. Does the  
pdf ability need any additional dependencies? If not, shouldn't we  
enable pdf all the time rather than putting it in a variant?
