According to the [api](https://photonstorm.github.io/phaser3-docs/Phaser.Display.Bounds.html#.GetBounds) it returns a Phaser.Geom.Rectangle, which provides a [contains](https://photonstorm.github.io/phaser3-docs/Phaser.Geom.Rectangle.html#contains__anchor) method.

However, this code:

```
Phaser.Display.Bounds.GetBounds(polygon).contains(x, y)

```

yields this error:

```
Uncaught TypeError: Phaser.Display.Bounds.GetBounds(...).contains is not a function

```

Why?

It returns a Rectangle only if you pass one as `output`. A little confusing, I know.
