Summary:
UIColor can now accept ranges above 1.0 and below 0.0 to represent the Display P3 wide color space. But in SKShapeNode's fillColor, these ranges are not interpreted correctly, instead wrapping the values rather than clamping them.

Steps to Reproduce:
In the following example the fillColor's red value is set to 1.2:

let frame = CGRect(x: 0, y: 0, width: 200, height: 200)
let scene = SKScene(size: frame.size)
let node = SKShapeNode(circleOfRadius: 100)
node.position = CGPoint(x: 100, y: 100)
node.fillColor = UIColor(red: 1.2, green: 0, blue: 0, alpha: 1)
scene.addChild(node)

let view = SKView(frame: frame)
view.presentScene(scene)


Expected Results:
The node should should show a circle with a red fill clamped to it's maximum value, which for sRGB is 1.0, or the maximum allowed in the Display P3 color space.

Actual Results:
Instead, fillColor wraps the red value (1.2) to 0.2. The same applies for values below zero.
