Convenient initialisers for SwiftUI's LinearGradient view

LinearGradient.swift

import SwiftUI

public extension UnitPoint {
	var diametricallyOpposite: UnitPoint {
		UnitPoint(x: 1 - x, y: 1 - y)
	}
}

public extension LinearGradient {
	init(colors: [Color], towards end: UnitPoint) {
		self.init(colors: colors, startPoint: end.diametricallyOpposite, endPoint: end)
	}
	
	init(gradient: Gradient, towards end: UnitPoint) {
		self.init(gradient: gradient, startPoint: end.diametricallyOpposite, endPoint: end)
	}
	
	init(stops: [Gradient.Stop], towards end: UnitPoint) {
		self.init(stops: stops, startPoint: end.diametricallyOpposite, endPoint: end)
	}
}
