title: MinAreaRect angles - Unsure about the angle returned
body: <p>From the functions for MinAreaRect, does it return angles in the range of 0-360 degrees?
  I am unsure as i have an object that is oriented at 90 degrees or so but I keep getting either -1 or -15 degrees. Could this be an openCV error?</p>
  
  <p>Any guidance much appreciated.</p>
  
  <p>Thanks </p>
