  Unfortunately Android devices have much 
  greater variance in performance and tend to trail significantly behind iOS. 
  We were able to get our app running fairly quickly, 
  but the performance — specifically on touch events was not at an acceptable level even on higher end devices. 
  In addition at that early stage there was still a lot missing in the React Native Android feature-set that would
  have made getting our prototype to production level more time consuming than our iOS effort.

  path.addLineTo(childViewTopLeftPoint)
  path.addCurveTo(childViewTopRightPoint, withControlPoint1: arbitrary1Point, andControlPoint2: arbitrary2Point)

  path.addLine(toPoint: childViewTopLeftPoint)
  path.addCurve(toPoint: childViewTopRightPoint, withControlPoint1: arbitrary1Point, andControlPoint2: arbitrary2Point)

  path.addLineTo(CGPoint(x: 100, y: 0))

  path.addLine(toPoint: CGPoint(x: 100, y: 0))

  path.addLine(toArc:...)
