title: Interpolating Radian Angles?
body: <p>If I'm given a start angle of 1.0f, and an end angle of 6.0f, then what I really want to interpolate is not the 5 in between 1 and 6, but the smaller portion.  This will cause counter clockwise interpolation. How can I account of this when interpolating?</p>
  
  <p>Essentially, when given 2 radian angles from 0 to 6.283, how can I know if I should interpolate clockwise or counter clockwise based on which would be "shorter"?</p>
  
  <p>Thanks</p>
