Up to now, only the rendering part has been considered. While defining
the octave handle system, I think you should also consider UI elements,
even a very limited subset (a pushbutton with basic properties like
position, units, font/color and callback). This might have some impact
on your arhcitecture and the interaction between octave handle system
and the backend (you'll also need some kind of synchronization between
octave objects and the UI objects used in any toolkit).
