FishEyeList: performance issue when a large number of items are present

Description (last modified by )
Run test_FisheyeList.html. Click the button to create new items (approx 25). Now mouse over the items and the performance is really bad. It appears that every item is sized and positioned for each pixel that the mouse moves and performance begins to suffer as you add more items.

I'm ok with the change, but I'd also like to deprecate it in favor of the FisheyeLite ... I don't suspect FisheyeList will make the migration to 2.0

(In [22715]) Fixes #11239. Add rudimentary size/[position cache to the FishEyeList? items to improve mouseover performance.
Note: See
TracTickets for help on using
tickets.
possible (partial) fix to not size/position elements that have not obviously changed. Performance seems much better but still slightly sluggish.
