Certainly the goal should be for the bulk of rendering to be accelerated.

We'll see where 2D applications go.  Right now, they're still drawing very
little on the screen and using a lot of static images and text.  It seems
clear though that this may well change in the future.

What I'd like to do is to build an accelerated cairo implementation on GL
to provide a comfortable PS/PDF rendering model for 2D application
developers.  That may make all of our discussions about how to best 
accelerate X operations moot; 'X' applications may end up just using GL 
for all of the performance sensitive drawing where available and fall back 
to software on embedded systems that don't have GL support.

Cairo is much closer to GL than Render; although we would like to continue
to provide per-component compositing for improved text appearance on LCD
screens; and perhaps even extend that to geometric objects as well.
