Removed the zoom level offset hack

Browse Source 
In the Mapsforge library the offset is dependent on the tile size which is
in turn dependent on whether the tiles are hidpi or not. In other words
the Mapsforge library is broken and inconsistent between hidpi/non-hdpi
displays. GPXSee is consistent here and we have thus tochoose one zoom level
mapping (i.e. what zoom level corresponds to what resolution). Lets choose
"no offset" = more details on a given zoom level/resolution.
