[cairo] Pure Cairo UI ?

[Asko Kauppi]

Is there still no "pure Cairo" UI project, anywhere?  Sort of a  
window manager (not necessarily windows, in the traditional 2D  
meaning..) that would sit on top of the Cairo graphics engine, and  
manage multiple apps using Cairo for their graphics output.

Googling for +cairo +UI gives lots of NT4.0 mentions... yeap. :!

So, am I just asking the wrong question, or is the question okay but  
a bit too early?  Is my analogy of Cairo==Quartz2D, and Aqua==the  
missing link right?

I'd need it for this:
