Java Terrain generator doesn't center map around the origin.

[tundramagi]

Java Terrain generator doesn't center map around the origin. Thusly it can only generate maps only 1/4th as big as the whole radiant extends (32k or so).

Could this be fixed.

It's an excellent tool, but I'd like to make an ons map with opposing castles, and maybe some vehicles and thus I need more room.
