title: Calculating the position of points in a circle
body: <p>I'm having a bit of a mind blank on this at the moment.
  I've got a problem where I need to calculate the position of points around a central point, assuming they're all equidistant from the center and from each other.</p>
  
  <p>The number of points is variable so it's <code>DrawCirclePoints(int x)</code>
  I'm sure there's a simple solution, but for the life of me, I just can't see it :)</p>
