I'm looking for a simple example of how to implement the Clutter::Scriptable interface so I can script my custom Clutter::Actor's.  I don't need any custom properties right now, I just want to be able to script the properties of Clutter::Actor (width, height, position, etc.).

You can define a custom GType when deriving in C++. You must call the
virtual base constructor (weirdness ahoy) in your initializer list:
http://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/custom/custom_widget/mywidget.cc#n26

Then you can presumably just mention that GType name in your JSON
script.

If it helps, you can add regular GObject properties by just using
Glib:property_proxy<> as a member variable.
