title: Border clipped when drawing with bezierPathWithOvalInRect
body: <p>I am drawing a circle in my custom UIView's drawRect:</p>
  
  <pre><code>- (void)drawRect:(CGRect)rect {
    ...
    UIBezierPath *ovalPath = [UIBezierPath bezierPathWithOvalInRect:rect];
    [UIColor.whiteColor setStroke];
    ovalPath.lineWidth = 1;
    [ovalPath stroke];
  }
  </code></pre>
  
  <p>The oval is always clipped on the edge.  How can I avoid the clipping? Is insetting the rect the only way?</p>
