shifting a group of markers or positions at once

[routeconverter]

i have reviewed the PRE version. Maybe we have a misunderstanding.

Yes, I said I'm going to implement this in two steps. This first step fixes the distortion of the google maps for China, i.e. the GPS coordinates are correct, but the map is shifted southeast.

But then the offset in the track which I copied from external source is still there. (Google mymaps -> exp. KML -> into Google earth -> copy Google earth track info -> into Routeconverter) .

This is the second step: shift distored data. It is realized with the second step which I've just uploaded as a prerelease. With it, you can select multiple positions and drag-and-drop them in one step with the same offset.

Please test and report.
