Dear Sean,

I will be grateful if you can do a jar for me.

Also if possible can you look at the same area in the von Neumann neighbourhood as it is behaving in the same way.

Kind regards,

Stewart.

I just nailed a dumb bug in width vs height for grids using moore neighborhoods. The new version is out on the repository right now. If you need me to build you a jar file, I can do that. Let's see if it fixes things for you.
