Well it's it's a wrapper with its own window. The EZClasses (which are
only temporarily redirected until RO gets implemented on swing) also
needed this because they have additional args. A Window obviously has
its own as well.
We could give FreqScope an optional Parent, and a popUp window only if
there is none. Actually couldn't we add a method to SCView that does
this for any View? If no parent, then pop up an always on top window ,
and add the view with and inset of 4px. Put it right in SCView, and it
can be eliminated from a lot of other stuff!
I can add this it SCView, since it is basically already written, to
JSCView as well.
