clouseau: highlight everything that has a geometry

So, there is one problem, there is the case that you just have the
notation in eolian that a special object implements a interface, to
bring the actual logic to it, you are going to composite_attach a other
object to it. The problem then in clouseau was that clouseau doesnt know
a implementation does exist, so it didnt display the implementation.

The new solution uses eo to fetch the function pointer to the actual
implementation to know if the function is really implemented or not.
