We have decided to do away with marker support for this first cycle of
development (there probably won't be another cycle before the GEF 3.0
release). Although there is no support for generic markers, guides (which
can be used to align figures in the editor) will be supported.

If you look at the latest code in the repository, you will find some initial
work done for the rulers. However, we are doing some major re-workings on
it right now, so I wouldn't recommend that you work off of or use what's in
the repository. That's just to give you an idea of how far we have
progressed. We intend to wrap up this initial cycle for the rulers/guides
in a
couple of weeks.

> - Add markers (again, if the ruler/client allows it)
> 6) Clients should be able to contribute actions/buttons for the dead space
