## Usages

```fsharp
RadialGradientBrush(Point(0., 0.), Point(0., 0.), RelativeUnit.Absolute) {
    GradientStop(Colors.Black, 0.)
    GradientStop(Colors.Orange, 1.0)
}
```

#### Get access to the underlying RadialGradientBrush

```fsharp
let brushesRef = ViewRef<RadialGradientBrush>()

(RadialGradientBrush(Point(0., 0.), Point(0., 0.), RelativeUnit.Absolute) {
    GradientStop(Colors.Black, 0.)
    GradientStop(Colors.Orange, 1.0)
})
    .reference(brushesRef)
```
