suggestion: ability to select axis for rotate

I'd love to be able to change the axis point with the rotate behavior, and also maintain the center axis as an option. Imagine how cool it would be to have something swinging from the top (rotate device>rotate). I'm able to do it by placing a small dot outside of the element area, but it often makes the full element sit outside of the viewport and will not work swing at all, or sometimes will crash the player. I'm adding a link to my dropbox to illustrate. Check out the butterfly example, which doesn't work because half of the element sites outside the ipad viewport.

Thanks for all your hardwork! I'm loving all the new features.
