    It's a stdcall convention. Basically a Delphi routine is called from C,
    with the parameter count & parameters passed in through a pointer. I need
    to turn these parameters around into a standard Delphi method call.
    Solerman Kaplon pointed me to Innerfuse Pascal, which appears to have
    related code, though I'd have to trim the framework considerably :-)

    I want Delphi developers to create classes that descend from my class, and
    are instantly interactive with both native and SpiderMonkey code.
    Properties are working, and parameterless functions are good as well, I just
    need to get the parameters to work now. (Returning results from the
    functions are the next target :-)
