Free Transform Quadrilateral

I was making a filter for a tire/tank tread and realized how useful a free transform quadrilateral tool would be for this because I could basically make the tread by blending the different quadrilaterals together.

So I have looked at lua and am still very much in the dark, could someone either teach me the functions I need to make this component and try their hand at making the map script?

What I am looking for is map script that is exactly like the free rectangle compontent. It accepts color, and background colors. But inseat of the start and end x and y's for only two points, there are start and end x and ys for four points.

Bonus points if you could get the corners and bevel width in there too.
