It would be nice to have the all 3 vectors for the polygon mask scale, as well for the rotation.
Justification
Having a better control over the polygon mask, so it can became more useful in more situation, like when it happens to have a bunch of polygon to select witch are in front of others and i need to scale along the xy and not in the z, in order to just take that polygons by avoiding the ones witch front them
Implementation Details
just add the rotation and the scale vectors to the parameters
