The Gizmo use a simple PositionToPoint node to redistribute each pixel in his UV space position.
Works as the nuke default STMap but does exactly the opposite.
Can be used in many different ways.
I found it very usefull especially for reference to know where to draw a roto in uv space to be then distorted via STMap to mask a particular area of your CG render.
