Remapping a CGPoint for use with SKPhysicsJoints in a non CGPointZero anchorPoint Scene

Remap Point

//To be applied to the anchor point
func remapPoint(point: CGPoint) -> CGPoint {
    let correctedX = point.x + self.size.width  * self.anchorPoint.x
    let correctedY = point.y + self.size.height * self.anchorPoint.y
    return CGPoint(x: correctedX, y: correctedY)
}
