Rendering in Mondrian is now externalized into visitors. It should be pretty straightforward to write one for cairo
Athens has initially layered structure. The frontend you will be using (canvas , surfaces, etc) is implementation neutral. So, swapping a backend who doing the real work, will cost nothing from users perspective.

Hi!
Just wondering what is the status of Athen / Cairo for Pharo? We recently put some effort on exporting Mondrian visualization to HTML/Protovis to benefit from vectorial graphics...
Status: "Under development"
:)
It can draw almost everything morphic-related, except one little thing - text :) And now i'm on crossroads , what to do. Clearly, a StrikeFont(s) is state as they now, simply don't fit with scalable vector graphics engine. The bitmaps stored in memory are optimized for exact fit 1:1 of display pixel grid. So, at minimum it will require converting all fonts to use different bitmaps, before they can be drawn using Athens canvas.
Another thing is drawing strokes. It is a question how far i should go implementing a basic (and most probably fall-back) engine which using old BallooonEngine, which can only draw a coarse, barely anti-aliased strokes. Not saying it doesn't supports many things, like joint types, dashing , masking etc etc.
