Since image drawing (in clim-extensions.lisp) was excluded in McCLIM 0.9.1, I've implemented my (very primitive for now) own code for that in Springtail (http://www.zamazal.org/software/springtail/index.html). This is just to let you know that if anybody wanted to add image drawing support to McCLIM again, I'd like to cooperate.
