Probably; I don't really know how to resolve the Picture conflict 
otherwise, and I'm not sure if there is any value in doing so -- a Cairo 
that supports xlib (perfectly valid on the Mac) will probably be used by 
a totally different class of apps than one that supports Quartz. 
However, the problem only comes up in cairo-boilerplate.c, which is one 
of the very few places (if not the only one?) where all the different 
backends touch.

Maybe the solution is to just split out cairo-boilerplate into multiple 
translation units, so that we don't run into this?  Building a Cairo on 
OSX that supports both xlib and quartz should be possible (though as I 
said before I don't think it's a high value thing).
