Hi Andrew,

This may be an interesting development, although I think that you would have 
to add some geo features into the graphics view as well to make it 
interesting.  Things like "move this item to a geo position" instead of to 
just pixel coordinates and things like that.

However, there is a big no-no in the code.  You should not put private members 
into the MarbleWidget class.  That's what the MarbleWidgetPrivate class is 
for.  If you do, you will destroy binary compatibility.
