//     Function: GeomDrawCallbackData::upcall
//       Access: Published, Virtual
//  Description: You should make this call during the callback if you
//               want to continue the normal rendering function that
//               would have been done in the absence of a callback.
//
//               Specifically, this method will add the Geoms in this
//               node to the list of renderable objects for drawing.
//               If this callback was made on a CallbackNode, it
//               doesn't actually do anything, since only a GeomNode
//               holds geoms.

  // Go ahead and draw the object, if we have one.
