@Timowi: in Settlers 1 these map borders could be enabled and disabled (that's not easily possible in Widelands, because there is not space for a 7th button below the minimap) and I have to say that I always enabled them, because I just have problems to see where I am in an endless map. ;-)
Especially if the map is big for me the orientation is much easier when you know the (virtual) map borders. To make these borders as less eye-catching as possible, I only dotted every 5th pixel. So it's only an additional hint and should not bother anyone, I hope.
@SirVer: yes, I tested it with both renderers.
