2) no GPU, no OpenGL, just optimized rendering (one of this days I will write the novel "how we render world canvas nowadays"... it is a thriller end-of-the-world story)

we are thinking with Igor if a quartz native renderer has sense right now. Of course, in the long term, it has completely sense, but atm, I have the feeling that other more portable renderer (like an OpenGL renderer) is better investment.

Anyway, we still have some other stuff to do before:

- finish athens (including new text model)

- finish bridge

- test same with linux, windows

etc.

NICE work Esteban!

Does the AthensQuartzSurface, support all Athens related code? (paths,
paints,etc..) I will be more than happy to move away from the software
rendering of the current cairo backend.

Is Quartz work by GPU? is it use openGL?
