Description: Work around dot rendering bug
This patch from causes monotone-viz to use "rankdir=BT" rather than the -y
option to dot to flip the revision graph's direction. The -y option to dot
broke previously (Debian bug #573781) causing displaced arrows. The problem in
dot has since been fixed, but it's still possible people might encounter it.
Also, it looks like this patch will be committed upstream anyway.
