Scalable graphics with Shape

[stabbles]

Hi all,

How would I efficiently draw a path in a Shape with coordinates relative to the size of the Shape? Of course I could do something like:

Shape {
    id: wrap
    anchors.fill: parent
    ShapePath {
        strokeColor: "red"
        strokeWidth: 10
        startX: .2 * wrap.width; startY: .3 * wrap.height
        PathLine { x: .3 * wrap.width; y: .5 * wrap.height}
        PathLine { x: .1 * wrap.width; y: .4 * wrap.height}
        PathLine { x: .2 * wrap.width; y: .1 * wrap.height}
    }
}

but this feels like a cumbersome API with a lot of redundant bindings (one should be enough, right?)
