"Drawing" CATextLayer into a CGImageRef?

Hi there!

In my application I have a CATextLayer (timeLayer) in a CALayer (clockLayer). If I apply a shadow to my timeLayer and then animate clockLayer using a CATransform3D, it animates VERY slowly. I figured I would solve this problem by creating a "snapshot" image of the timeLayer, setting a new CALayers contents to the snapshot image, and then animating the new layer containing the snapshot. The problem is that I have no idea of how to achieve this. If you know any other way of solving my problem, or how I can accomplish the above, it would be very kind of you to share your thoughts.

Kind regards,
Tim Andersson
