How to draw arc corner using Bezier Path

Issue #673

To draw rounded 2 corners at top left and top right, let’s start from bottom left

let path = UIBezierPath()
// bottom left
path.move(to: CGPoint(x: 0, y: bounds.height))
// top left corner
path.addArc(withCenter: CGPoint(x: radius, y: radius), radius: radius, startAngle: CGFloat.pi, endAngle: CGFloat.pi * 3 / 2, clockwise: true)
// top right corner
path.addArc(withCenter: CGPoint(x: bounds.width - radius, y: radius), radius: radius, startAngle: CGFloat.pi * 3 / 2, endAngle: 0, clockwise: true)
// bottom right
path.addLine(to: CGPoint(x: bounds.width, y: bounds.height))
path.close()
