I don't understand WebIDL at all, but in http://dev.w3.org/2006/webapi/WebIDL/#dfn-overload-resolution-algorithm it sounds like an argument with ECMAScript value 'undefined' would not add object types into the 'types' set, and so it wouldn't match any of the drawImage overloads (which all expect some object type as their first argument) and should trigger a TypeError. (It'll never reach the stage of converting the ES value 'undefined' into an IDL value 'null', since it never gets far enough to pick a function to convert the argument list for). (I could be completely misunderstanding everything, though.) The changes to the other tests look fine to me. -- Philip Taylor pjt47@cam.ac.uk
