//     Function: EggJointPointer::add_frame

//               otherwise (e.g. for a static joint).

//  Description: Moves the vertices assigned to this joint into the

//       Access: Public, Virtual

//               Until do_rebuild() is called, the animation table is
//               not changed.
//
//               The return value is true if all frames are
//               acceptable, or false if there is some problem.
