	Fair enough; I'd also be in favour of adding a 'property_bag_widget' or
somesuch to libbonoboui that would list the contents of the
PropertyBag's properties, and let them be manipulated, since this could
be easily shared between glade, and various other projects.

	It sucks to inherit from PropertyBag; badly, for all the reasons
discussed before.

	Consider if you can use a simple PropertyBag interface instead of
ZoomRegion altogether ?

	Can you have 'magFactor' as a property instead of a 'setMagFactor'
method ?

	Look forward to seeing it.
