all ways go to Rome
but we, in North Europe, need to go from north to south direction, it is really better! and to do it is a long land map in this direction better as lot of short land maps in the other ;-)
in other Linux distributions I use KDE for this operation of turning the direction of my screen for a short time (it goes also in Slax since the new version having as beta only 180 Mb).
what is possible to do in SliTaz (the goal is to preserve the good resolution of my high resolutions screen of course, not to stretch the view in bad direction to feel the printer paper with «empty zooming»!)
