Comment 4 for bug 203423

The current version is still not nice to use, some issues are:

- the zoom starts too quickly, it's not easy to move the mouse pointer over a country in less than one second which means it zoom on the wrong area while you are still moving, maybe it should zoom after you stop moving the mouse for a second or so, that would allow user to select slowly their location?
- the zoom out effect needs a delay too, it's too easy to get the mouse pointer out of the widget while scrolling
- the zoom is not correctly centered, putting the mouse pointer over the France make it zoom in the north of England for example
