Hi,
Attached are files which I propose to add to contrib/ to allow image display in the repl. The Common Lisp support is entirely non-existent, but I have prototype code using the slime support to do manipulations of graphical objects in R: http://doc.gold.ac.uk/~mas01cr/tmp/swankr-images.png displays an example.
I'd like to put this or something like it in; I'm asking for review of this approach and implementation.
Cheers,
Christophe
