Please remember to delete once you're done debugging.

Ditto

     }

Ditto.

     surface = gfx::GLSurface::CreateViewGLSurface(false, handle.handle);
     if (!surface.get())
       return NULL;
     surface = new PassThroughImageTransportSurface(manager,
                                                    stub,
                                                    surface.get(),
                                                    handle.transport);
   }
 
   if (surface->Initialize())
     return surface;
   else
     return NULL;
 }
