[PD-dev] devel_0_37: widgetbehavior, garray dirty flag

Maybe my ignorance in this respect comes from the fact that i try to avoid
GOPs whenever possible...
However, it's not clear for me how the cloning of the original gobj behavior
differs from defining a whole behavior struct for a graphical object (which
is considered to work for GOPs). Could you please elaborate on this?

This implies that all graphical objects are unstable.....

If you could implement that i'll happily use it....

best greetings,
