world_data::unk_482f8 and world::pathfinder

[ab9rf]

world_data::unk_482f8 appears to be the same type as world::pathfinder except for the eight fields at the end of the latter structure, which leads me to suspect either that the latter has an member instance of the former as its first member

after further research, it turns out this is not the case; the structures are similar but not identical as one is a heap for 2D pathfinding and the other is a heap for 3D pathfinding
