boost::trackable confusion

[Angus Leeming]

 #warning I have zero idea about the trackable()
 InsetGraphics::InsetGraphics(InsetGraphics const & ig)
        : Inset(ig),
-         boost::signals::trackable(ig),
+         boost::signals::trackable(),
          graphic_label(uniqueID()),
          cache_(new Cache(*this))
{
        setParams(ig.params());
}


Fortunately, I do ;-)

trackable is tracking the existence of this instance of the class, or will 
do once a signal is connected to return to it.

There has been no attempt yet to connect a signal from the GraphicsLoader to 
this->statusChanged() so there is no need for trackable to track anything 
yet.

Make sense now?

(I'll fix it.)
