Obs
Worlds without infinite terrain are completely black outside the normal world area.
This affects every map display, like the 2D editor, as and some things in-game for:
Black waypoint point lines/circles, which extend into outside area, disappear
Black markers (both shaped and icons) cannot be seen there
Map grid position coordinates are not visible when focus is at the edge of the map

Exp
The outside area should be visible. {F18580}
