Bug#737781: [PATCH 0/3] Graph::Writer::GraphViz graphviz attribute support

[Ian Jackson]

I'm using Graph.pm and wanted to feed the results to dot.
Graph::Writer::GraphViz seemed like the right thing.  However, I found
that I wanted to set some graphviz attributes support for which was
lacking in ::Writer:GraphViz.

Here is a series of three patches to improve this:

 1/3 Honour edge attributes `style', `label', `color': pass
 2/3 Document the edge and vertex attributes which are passed
 3/3 Provide a "graphviz" attribute for setting other

I'd appreciate it if you would let me know whether you approve of this
approach.  Best of all would be for you to include this in your next version.

But I'd also like to know what you think of it so that the Debian
maintainer can know whether it's a good idea to apply this patch ahead
of it being in upstream.

Thanks,
Ian.
