Dear Emmanuele,

Thank you for your opinion.
As for the facts you mentioned, yes, there is stuff implemented in
pigment-python that is not available in pigment:
 - The only animation framework available for pigment is indeed the one
of pigment-python. That sucks, I agree with you, and that's why I've
been working on a new project: the PAF Animation Framework[1], that aims
at being a standalone generic animation framework; it will be used by
pigment in the future, and is designed to work well with other
libraries: GTK+, clutter, any GObject library, or even any non GObject
library. For the moment, it is in a "code skeletoning" and API
definition stage, anyone interested is welcome to participate or simply
give ideas. As for dates, I think a first version of PAF should be
available in less than a month, and pigment 0.5 will make use of it
(that should be available at the end of summer or at worst in autumn).
 - The scene graph-like grouping system is part of pigment-python as
well. There won't be any solution for that in pigment 0.3/0.4, but
pigment 0.5 will provide a scene graph API in C (again, end of summer or
