Very general.  The application just wants to have the ticks placed 
according to its rules, I guess.

What I meant by random is not the tick placement, but the box that the 
user selects to zoom into.  There's no way for whomever manually places 
the ticks to anticipate, say, more denser ticks in an area the viewer 
might look at more closely, i.e., zooming is really something only 
gnuplot controls.  So if the rule is to go to auto-placement in zoom 
mode, and back to manual placement when leaving zoom mode it might be 
just fine.

Perhaps one could argue that if the user zooms in just a fraction to cut 
of some portion of the view, say, zoom 0.95 of the view, then the ticks 
might jump to something different...or maybe the programmer doesn't want 
any ticks and when zooming the ticks re-appearing might be undesired. 
Maybe there is rare cases where auto-ticks in zoom are unwanted.
