Simple Vignette / Nuke Gizmo

This is a Nuke Gizmo that allows you to Vignette the edge of an image.

A Vignette is a subtle darkening of the image at the edge of frame that can help lead the eye to the center of the image. 

Just copy / paste the content of the Gizmo in your Nuke script.

This Gizmo will allow us to dynamically adjust the Vignette to the Resolution of the incoming image and offers an option to output the Vignette as a Matte if we choose to.
