title: How to reverse the point order of a CGPath
body: <p>I want to draw a Circle with Letter punched out of it. to do this, I need to stroke the circle clockwise and the letter counterclockwise.</p>
  
  <p>That is all good and well, but when I get the letter path using Core Text I can't figure out how to essentially reverse the path. NOT MIRROR or ROTATE or anything...that is straightforward enough. I want the point stroke order to be counterclockwise.</p>
  
  <p>it is actually hilariously difficult. I've had entirely too many visual 'off by one' errors.</p>
