title: Creating a CALayer with unit vector coordinate system
body: <p>I would like to create a CALayer that manages it's sublayers' position using unit vectors. This would allow the base layer to be resized while keeping all of it's sublayers in the same relative position. </p>
  
  <p>Dose this have to be done manually or is there a way to change the coordinate system of a CALayer to achieve this?</p>
  
  <p>I am trying to implement an easy way to handle window resizing. By using unit vectors, all of the sublayers will remain in the same relative positions as the main layer is resized.</p>
