Re: [racket-dev] Working Cairo-bindings for Racket?
No, I'm suggesting that while I think a real binding to cairo would be a good idea, it should be based on the code already in racket/draw and that the code in my library is probably useless. Feel free to use any of it that you find useful, though.

Re: [racket-dev] Working Cairo-bindings for Racket?
Instead of changing my Planet package, it would be better to provide an FFI to cairo based on the existing one that's in the library you mention. I don't think any of my package would be useful for that, though.
