A commit log comment for Bug 8227 mentions that method overloading may be a
better long-term approach to optional arguments in JavaScript functions, which
is the same conclusion I reached after thinking about this problem for a few
days.  I will try to fix the above problem by teaching CodeGeneratorJS.pm about
overloaded methods.  Here's Maciej's comment from that commit (r13726):

* bindings/scripts/CodeGeneratorJS.pm: Added support for
ConvertUndefinedToTrue, for benefit of scroll methods where omitted arguments
should be treated as true.  However, maybe explicit overloading in the IDL
would be a better long-term approach for optional arguments.
