I also considered that possibility, but I found it way less efficient than
having specific methods
virtual void base_graphics_backend::figure_property_changed(...)
Indeed, from the octave point of view, when such notification method
is called, it knows the object and property (because it's called from
the set_xxx handler), so it can call a specific method directly.
OTOH, using generic signature as you propose would just force
the backend to re-do a lot of string comparisons to know which
property was changed.
Note that using specific notifiers does not prevent the backend
from delaying its reaction.
