     int start_atix, stop_atix <-- for discrete objects, we need
     something like this that would enable pymol to skip atoms not in the
     discrete state...question is: are these atoms sorted together right
     now or not? probably not, and if not then we need to change sorting
     for discrete objects to be state-dependent, but this could screw up
     byres/bychain actions which assume such atoms to be adjancent...
