Is it possible to override SceneView / AnimX Private Types?

I'm currently trying to extend the SceneView, there is some functionality that I've been missing that I used to have in other engines that I would like to implement into Unity. I noticed that it tends to work fine until I override OnGUI().

If anyone knows of a way to force the extended SceneView to render (Repaint isn't working in Update()), or if it's even possible, you would be godsend!

Also I found some really interesting base structures in the Assembly Browser that I'm extremely curious about:

         this.m_Position = new AnimVector3 ();
         this.m_Rotation = new AnimQuaternion (Quaternion.LookRotation (new Vector3 (-1f, -0.7f, -1f)));
         this.m_Size = new AnimFloat (10f);
         this.m_Ortho = new AnimBool ();

Cheers, and Thanks!
