[ka-Map-users] Overlays with dynamic information

When using setInterval, it will trigger a new loadXML() running after
delaying for a specified time period, even the last running is not over.
And there's asynchronous call during the procssing of loadXML(). I wonder
whether it is safe and efficient.
When using shiftObject, you must hold the old lon/lat value, call
geoToPix() twice and calculate delta X and Y for each point. While using
updateObjects, you just need to assign the current lon/lat value to every
obj. But on the other hand, you can call shiftObject to set each point
separately instead of updating the points all at once.
Besides, I have some questions. What about the performance of
wz_jsgraphics, is it necessary to use it?
Sorry to bother you, but I'm really interested in dynamic overlay function
and quite grateful for your work.
