As requested it now has chunk lines.
Accurate chunk lines
It took me a lot longer to release a version with chunk lines then I had planned.
In part this is due to me being a lazy bum and in part it is due to some unexpected weirdness in the map.
When you view the ingame map you are presented with a text box that tells you in what chunk you are standing. It also tells you what chunk you are currently pointing at with your mouse.
Based on the idea that the chunk lines would be on the spots where the name changes on mousing over it I made a chunk grid and applied it over the maps.
I logged in test the map and ran to the nearest chunkline on the map and passed it without actually reaching a chunk line.
After I had found the real chunk line location I discovered that the chunk grid the mouse "sees" when you are mousing over it is way of from the actual location of the chunk lines.
In this pic the black lines are the actual location of the chunk lines and the red lines are about where the the bit of the UI that's responsible for mouseover events thinks the chunk lines are.
The red X is where my mouse was pointing (screenshot doesn't take the pointer) and the blue circle is around my location.
As you can see I am standing in Dahknarg chunk, the text box correctly shows this in green text.
My mouse points at the location of the red X (inside Dahknarg chunk) and the text box incorrectly tells us that I am pointing at Halgarad chunk (the white letters).
That and similair crap + the fact that I am lazy led to this simple chunk line update taking a lot of time.
