Dear Maintainer,

I feel that graphviz (the binary package) ought Suggest or even Recommend
libgvplugin-neato-layout8. It is recommended by graphviz-tools, but if
graphviz-tools is removed, the layout plugin will typically go with it. This
prevents the 'neato', 'circo', etc. tools (included in graphviz) from working:

[schwarzgerat](0) $ circo
There is no layout engine support for "circo"
 Use one of: dot
[schwarzgerat](1) $

IMHO, either 'circo' and friends ought be packaged in graphviz-tools (instead
of graphviz), or graphviz ought Recommend this layout plugin.

This seems to be caused by a change in graphviz (used via
libgraphviz-perl):

… which is the error we are seeing.


Maybe we should just depend in graphviz-tools in libgraphviz-perl?
