title: What does yellow tinting represent when using "color misaligned images" on iPhone/iOS
body: <p>so--i switched on "color misaligned images" to improve drawing performance in our app. The documentation states: </p>
  
  <blockquote>
    <p>Puts a magenta overlay over images
    whose source pixels aren't aligned to
    destination pixels</p>
  </blockquote>
  
  <p>I don't know what the yellow means however. (There is a "Color Offscreen-Rendered" option that uses yellow... does "Color Misaligned Images" also turn on this option?)</p>
  
  <p>Anybody know?</p>
  
  <p>TIA</p>
