I'm interested if an `SKSpriteNode` can be made to imitate the behavior of a `UIView` where I can specify border and corner radius? 

```
self.view.layer.borderColor = [UIColor lightGrayColor].CGColor;
self.view.layer.borderWidth = 2;
self.view.layer.cornerRadius = 2;
self.view.layer.masksToBounds = YES;

```
