Image is not centered

[Sworddragon]

The same command as from #216:

/usr/local/bin/c10t -o /tmp/%d:%d_%d.png -p 496 -w /srv/minecraft/world -R 1

The chunk will be shown in the top left of the image but I think it should be centered instead.

I do believe that this is intended behaviour, there is the --center argument that you should use together with --radius to achieve what you want.
