title: Uiimage from UIView: higher than on-screen resolution?
body: <p>I've got a UIView which I'm rendering to a UIImage via the typical UIGraphicsBeginImageContextWithOptions method, using a scale of 2.0 so the image output will always be the "retina display" version of what would show up onscreen, regardless of the user's actual screen resolution.</p>
  
  <p>The UIView I'm rendering contains both images and text (UIImages and UILabels).  The image is appearing in the rendered UIImage at its full resolution, and looks great.  But the UILabels appear to have been rasterized at a 1.0 scale and then upscaled to 2.0, resulting in blurry text.</p>
  
  <p>Is there something I'm doing wrong, or is there some way to get the text to render nice and crisp at the higher scale level?  Or is there some way to do this other than using the scaling parameter of UIGraphicsBeginImageContextWithOptions that would have better results?   Thanks!</p>
