Render nodes in landscape

[sdiemert]

A very small (unimportant) feature request....

Sometimes rules take up a lot of vertical space when rendered by GraphViz. This can be mildly annoying when incorporating the rule graphs into a document. Can there be an option to render in "landscape" orientation to reduce the amount of vertical space used?

I believe GraphViz supports this functionality directly, so it should be simply binding a option/argument in GRAPE to this option in GraphViz.

Anyways, this is super low priority, but it would be nice touch :-).
