title: Get Depth at Color position, Kinect SDK
body: <p>I am looking for way to (as quick as possible) get the corresponding depth to a color pixel from the Kinect camera.</p>
  
  <p>I have found the MapDepthFrameToColorFrame function. But that only gives me the color at a certain depth position, I want the opposite.</p>
  
  <p>The reason I want this is that I will be able to click on a position at the RGB image and get the position to that pixel.</p>
  
  <p>Is there a way to do this faster than looping through all results from MapDepthFrameToColorFrame?</p>
