You are correct. It seems what was causing problems was actually the
zoom, as I may zoom in to results on a given page. And temporarily
disabling the zoom event handler right before zooming to results
solves the zoom problem.

I will look into that, however, the user can drag with a window open.
Btw:
I just noticed that expanding the results bounds when the JS pans to
view outlying result isn't working as well as I thought. Panning
takes some amount of time, what's happening is:
1. I call set center
2. I expand the result bounds
3. It finishes panning sometime later so the result bounds weren't
expanded to new viewport.
4. User moves even one pixel, and it reloads the results, because
viewport is not in results bounds.
I suppose it isn't horrible, but from a user experience perspective,
it just seems strange:
For example:
http://devasp.northcarolina.edu/iic/exams/find.php?q[text]=&q[location]=rocky+mount%2C+nc
go to the last page of results, then move a little, it reloads results
on left.
