Polygon masks from alpha mattes

I would be excellent to be able to get a polygon mask from any black and white matte.
With a new node in fusion maybe, or new options in an existing one.

The "AI" for the magic mask has to work harder with tons of details, but it still works works (relatively) well and pretty quickly.

So I think it would be even easier and fast to detect white edges of a matte and convert it to an animated mask.

Imagine the possibilities with that.
