| Subject: | New Option: random_seed |
According the the NEATO users manual, if the "start" attribute is set to a
number, graphviz will use that number as the random seed, but the layout
will still be deterministic. This is useful if you want to repeat the same
layout after you've found a good one. so i added an option to
new(random_seed => '[NUMBER]')
attached is a patch.
