I want to scale the font size of a `Label` like this:

```
Label {
    font.size: font.size*0.8
}

```

Of course this creates a binding loop. Is there a way to do this without creating a hidden `Label` element?

```
Label {
    id: hiddenLabel
}

Label {
    font.size: hiddenLabel.font.size*0.8
}

```

Scaling the whole label is not optimal because the text quality decreases:

```
Label {
    scale: 0.8
}

```
