Makes sense. There is one issue that will have to be resolved ... how
do we update the property dialog widgets for side-effects? One way is
to use the actual DiaObject itself. Properties get applied instantly,
if we are careful with undo. An earlier discussion in a bug about the
behaviour of the Properties Dialog is very relevant to this topic:

http://bugzilla.gnome.org/show_bug.cgi?id=488270
properties dialog should have a button to undo all changes made while
interacting with the dialog
