title: Applying multiple transforms to a UIView / CALayer
body: <p>Is there any problem applying multiple transforms to a UIView and it's corresponding CALayer?</p>
  
  <p>Specifically, can you "mix and match" CATransform3Ds with CGAffineTransforms without running into issues?</p>
  
  <p>Also are there any problems with setting some transforms directly while animating another transform change simultaneously?</p>
  
  <p>Are there any "rules" for how this should be done, or any design patterns for this?</p>
