    /// This project makes a new window out of a graphics path that has been traced on this forms space.
    /// Features include: Smoothing capability via turning sub paths into curves, etc
    /// Use point for stretching curve.
    /// 
    /// Have some kind of window that allows the user to set or view smoothing factor.
    /// The user can then see the shape in the smoother form side-by-side with the original.
    /// The user can then choose which one to make the new window with.
    /// Show the smoothing factor as percentage reduction in number of points = 1-(p1/p2)
    /// Have user choose some basic aspects of the form.
    ///   min and max buttons
    ///   border style
    ///   inflation size
    ///     have another form that has a slider so the user can graphically size the shape
    ///   opacity
    ///   background color
    ///   background image
    ///   Quit button on form
