Sweet! Hopefully you don’t mind me posting this back onto the list, but I thought it’d be worth letting the general populace know that NSImage is apparently more capable at reading PICTs than the libpaint-based solution, making it possibly worth a small bit of special-case code for OS X-based hosts.
