title: Call Apple-specific OpenGL commands through MonoTouch/OpenTK
body: <p>If I understand things correctly, Apple's OpenGL ES 2.0 implementation uses some methods from OpenGL ES 3.0, for example</p>
  
  <pre><code>glBindVertexArrayAPPLE
  </code></pre>
  
  <p>or</p>
  
  <pre><code>glBindVertexArrayOES
  </code></pre>
  
  <p>instead of</p>
  
  <pre><code>glBindVertexArray
  </code></pre>
  
  <p>It seems that the OpenTK compilation that gets delivered with MonoTouch does not include either of these methods, although there exist OpenTK bindings for them, see for example line 229 of <a href="http://www.opentk.com/files/doc/_g_l_core_8cs_source.html" rel="nofollow">http://www.opentk.com/files/doc/_g_l_core_8cs_source.html</a>.</p>
  
  <p><strong>Is there any way I can use these features in MonoTouch? Maybe some way to call them through a P/Invoke?</strong></p>
