on the Glance GUI (https://github.com/rgleichman/glance). We're now using Cairo to draw the nodes, I've started adding support for undo, and I've been doing .

Any comments on your experience with Cairo so far?

I prefer the declarative style of something like diagrams over Cairo's imperative statefull style. With Cairo I have to keep track of state like the color and the current position and remember to call draw commands. diagrams has a Cairo backend, so I hope to eventually get that hooked up so I could hopefully use diagrams for everything.
