title: Where is the official documentation for CVOpenGLESTexture method types?
body: <p>I tried google and stackoverflow but I cant seem to find the oficial documentation for functions that start with <strong>CVOpenGLESTexture</strong>. I can see they are from core Video, and I know they were added on iOS 5 but searching the documentation doesnt give me anything.</p>
  
  <p>I am looking for the information about the parameters, what they do, how to use them etc. like in the other apple frameworks.</p>
  
  <p>So far all I can do is command click on it to see the information but this feels super weird. Or is there a way to add this so it can be displayed on the quick help on the right on xcode?</p>
  
  <p>Thanks and sorry if it is a stupid question.</p>
  
  <p>PD: The core Video reference guide doesnt seem to explain these either.</p>
