Muzak,
Nice addition, thanks for pointing to it.
Frankly, I'd prefer to avoid calling commitProperties() after *each*
of the setters...
Anyway, this way looks better than my enter_frame trick :-)
However, the problem " none of the setters are called if no
inspectable params were changed" still remains. So we have to
duplicate default values in [Inspectable] and constructor/declaration
(or some init function)
