Tick labels not stable (their values change) when scrolling the plot area

[GoogleCodeExporter]

At certain zoom levels where tick labels represent non-contiguous time units 
(e.g. every other year, 
every 4 months, etc.), a given label will sometimes oscillate between multiple 
values when scrolling 
the plot left or right.

To witness this issue, go to  http://timepedia.org/chronoscope/demo/advanced/ 
and zoom in on 
the top chart until the year ticks are spaced 3 years apart (e.g. 1975, 1978, 
1981, ...).  Now position 
the mouse pointer above one of the year ticks and scroll left and then right.  
Notice how the year 
skips around.

For any given frame, the tick labels are correct.  The main issue has to do 
with negative user 
experience, in that the user does not get the sense that the ticks are actually 
scrolling left or right 
as they drag the plot area.
