I'm actually having second thoughts about this -- there is some  
oddness in some cases (un-antialiased fonts in particular) with the  
cgfont code that makes me rethink this plan for now.  The problem  
seems to be that I'm getting much more detailed metrics than before,  
which are then not playing well with various rounding bits (e.g.  
x_bearing of 1.01 and the like).

Worst case, we may just have to punt on the whole supported-quartz for  
1.6 thing (sadly -- maybe just fonts?), because depending on the size  
of the issue I'm not sure I'll have time to fix everything quickly.   
The issue is just with unantialiased text though, so I'm hoping that  
it'll be fixable in a straightforward fashion.

I have compat shims in for 10.4, and text seems to work as well there  
as on 10.5; however there are some other test suite failures that seem  
to be due to CG bugs that have been fixed since then.  I don't think  
there's much that we can do about that.
