title: Can I adjust a CGRect with a UIEdgeInsets?
body: <p>I've got a <code>CGRect</code>, and I'd like to adjust it with a <code>UIEdgeInsets</code>.</p>
  
  <p>It seems like perhaps there might be a built in function that does this. I've looked for a <code>CGRectAdjustByInsets</code> or functions with some other <code>CGRect…</code> prefix, but I didn't find anything.</p>
  
  <p>Should I code my own?</p>
