title: How to take snapshot of the SCNView?
body: <p>SceneKit provides a method <code>snapshot()</code> for rendering view's scene into image object. But whenever I used this method the result comes <code>"&lt;uninitialized&gt;"</code>. I even tried to get image from current image context; App crashes logging as <code>SceneKit: error, Failed to bind EAGLDrawable: &lt;CAEAGLLayer: 0x17422c380&gt; to GL_RENDERBUFFER</code></p>
