 Did you mean whether we can draw within a single frame
 OpenGL and non-OpenGL objects ?

 - This is not implemented by ROOT.

 - Open GL standard doesn't define this feature and it is up to
   Open GL implementation (vendor)

 - Open GL does produce the pixmap arrays. Those can be used to paint the 
   TPad  "background".  This way one has  more freedom with GL implementation
    but he is restricted  with "GL double buffering" mode.

  With my best regards,
                                           Valery
