One more demonstration of null biomes, this time with raw biome density values filled in on nulls instead of vanilla biomes.

Another examination of an uncompleted null biome.

I think I've fixed the major breakage with the roads stuff, and it related to a tiny stupid mistake in the biome code. However, too many road intersections are still being deleted and it's resulting in null biomes occasionally. Studying the big one here, looks like a road isn't being drawn where it really should be. WHY

Did a LOT of tweaking to my biome generation code, but it's still really messed up. Generated this map and flew around a bit to try and visualize the issue...

Turned off neighborhood polygonning and instead just let choked biome values show through to see why we're going from rural directly to urban biomes. Looks like when the biome value get choked, suburban biomes become very rare....

Test world for Alternate Terrain Generator. Some really cool formations, I love it.
