Hi Dmitri,

I think there are length restrictions on this email list. They might have 
prevented your posting.

drawing.lisp should have used cairo. It was a rather naive attempt. If you'd 
like to learn cells, you might try replacing the actual drawing primitives in 
drawing.lisp with cairo calls, if that makes sense (I haven't looked at it in 
detail). If you have questions about cells, you can ask on this list.

It is hard to say without an example showing what it does. Do you have one, 
ideally something that can run as part of the existing test-gtk demo?

Did you intend this patch as an addition to the cells-gtk distribution, or 
just an example of how to do drawing?

What is cysgu about? It appears to only be (sleep .01), but is that a stub for 
something else?

+		       (gtk-main-iteration-do nil))
+		 (funcall (cysgu app) app))

I don't, but maybe someone else here does. Sounds interesting though.
