Improved placemark sorting to make layouting stable with placemarks on same zoomLevel
Review Request #123322 - Created April 10, 2015 and submitted
Sorting takes place after joining placemarks from all relevant tiles. The order is:
1) zoomLevel (placemarks were already sorted by zoomLevel before this patch)
3) pointer value
This prevent cases like label flickering for same zoomLevel placemarks that are close to each other and moving.
Did testing and debugging to confirm that the order is exactly as intended. No unit tests are provided.
