    @input Draw: Activate to draw the ellipse on this frame. The input must
        be (indirectly) called from an `On Render2D` node.
    @input Color: The color of the ellipse.
    @input Filled: Whether the ellipse is filled or only the outline is drawn.
    @input Strength: The line strength if the ellipse is not filled.
    @input Segments: How many line segments should be used to draw the
        ellipse. 0 (default) = automatic.
    @input Center X/Y: The position of the ellipse's center in pixels.
    @input Width: Width of the ellipse in pixels.
    @input Height: Height of the ellipse in pixels.
