    @input Draw: Activate to draw the string on this frame. The input must
        be (indirectly) called from an `On Render2D` node.
    @input String: The string to draw.
    @input Font File: The filename of the font (including the extension).
        If empty and Zui is _enabled_, the default font is used. If empty
        and Zui is _disabled_, nothing is rendered.
    @input Font Size: The size of the font in pixels.
    @input Color: The color of the string.
    @input X/Y: Position of the string, in pixels from the top left corner.
    @input Angle: Rotation angle in radians. Rectangle will be rotated cloclwiswe
        at the anchor point.

    @output Out: Activated after the string has been drawn.
    @output Width: String Width.
    @output Height: String Height.
