lingering problems with the default approach for a long thin world, so now I'm preferring
the HANDSETVIEWERPOS optoin. The other way WORKS, but I don't TRUST it anymore for this
paritcualr world as I have so often seen it arbitrarily put my view BEHIND the world 
(negative z), though this coudl have been due to some cCritterViewer trackplayer code
thats' been recently revised.  So you can probably comment out HANDSETVIEWERPOS.*/
