title: Inset for non-rectangular shape
body: <p>I am wondering is there any functionality in Core Graphics that will let you specify an inset for a non rectangular shape ie something comparable to CGRectInset? I'm creating a path that is comprised of a bunch of quadratic bezier curves which make up a special type of elipse, and I'd like to fit in a smaller type of elipse inside of it. Yes, I know I could probably do this manually, but wondering if Apple has an easy way to do it?</p>
