title: iPhone OpenGL ES missing functions should be there - glBlendFuncSeparate etc
body: <p>I'm using OpenGL ES 1.1 on the iPhone, and I'd like to use the following functions:</p>
  
  <pre><code>glBlendFuncSeparate
  glBlendColor
  </code></pre>
  
  <p>With their related constants. These didn't exist in early iPhone GL implementations, but according to this page:
  <a href="http://developer.apple.com/iphone/library/releasenotes/General/iPhone30APIDiffs/index.html" rel="nofollow noreferrer">http://developer.apple.com/iphone/library/releasenotes/General/iPhone30APIDiffs/index.html</a></p>
  
  <p>they should be there in 3.0+, which I'm building for. But I'm getting "implicit definition" warnings. What do I need to do to get those functions?</p>
  
  <p>Thanks!</p>
