I'll hold this change for the multi-texture desktop CL.

 
   // Sets the canvas on which the desktop will be drawn. Caller must feed a
   // full desktop frame after calling this function.
   // If |canvas| is nullptr, nothing will happen when calling Draw().
   void SetCanvas(GlCanvas* canvas);
 
   // Draws the desktop on the canvas.
   void Draw();
 
  private:
   std::unique_ptr<GlRenderLayer> layer_;
   webrtc::DesktopSize last_desktop_size_;
 
   DISALLOW_COPY_AND_ASSIGN(GlDesktop);
 };
 
 }  // namespace remoting
 
 #endif  // REMOTING_CLIENT_OPENGL_GL_DESKTOP_H_
