class TEveTrackPropagator: public TObject, public TEveRefBackPtr

 TEveTrackPropagator

 Holding structure for a number of track rendering parameters.
 Calculates path taking into account the parameters.

 This is decoupled from TEveTrack/TEveTrackList to allow sharing of the
 Propagator among several instances. Back references are kept so the
 tracks can be recreated when the parameters change.

 TEveTrackList has Get/Set methods for RnrStlye. TEveTrackEditor and
 TEveTrackListEditor provide editor access.
