don't use keyword args to calc_footprint (for JS compat)

keyword arguments only work properly in Transcrypt if we have the `__kwargs__` pragma enabled on the funtion that accepts them. Since we are giving all the arguments here, it's easy enough to just pass them as positional arguments, eliminating the need for keyword arguments here
