You mean if we want to update a layer style and that's impacting all three styles ?    Indeed, I see the duplicate style, but they are not following each other: I don't see what could be done here. If we are going with `one layer = one style`, regardless of zoom, we'll have to read the zoom value each time we are in `Feature2Texture` or something else. I think this is slowing things, and complicating them.
