Canvex was originally written for and tested in Firefox 1.5/2.0 and Opera 9. It wasn't tested in Safari (due to lack of Mac). I think the relevant bug is https://bugs.webkit.org/show_bug.cgi?id=13537 which was actually caused by passing 0 sizes to drawImage, not by non-finite values. -- Philip Taylor exc...@gmail.com
