    @input Draw: Activate to draw the Render Target image to screen. The input must
    be (indirectly) called from an `On Render2D` node.
    @input In: Activate to get the Render Target image of the render 2d draws.
    @input Draw Width/Height: Size of the Render Target image in pixels.
    @input Image: The filename of the image.
    @input Color: The color that the image's pixels are multiplied with.
    @input Left/Center/Right: Horizontal anchor point of the image.

    @input Top/Middle/Bottom: Vertical anchor point of the image.

    0 = Top, 1 = Middle, 2 = Bottom
    @input X/Y: Position of the anchor point in pixels.
    @input Width/Height: Size of the sub image in pixels.
    @input sX/Y: Position of the sub anchor point in pixels.
    @input sWidth/Height: Size of the image in pixels.
