Comment 4 for bug 182832

a work around is to use zOrder.instead of selection order. It is less handy, but still makes sens (at least for "interpolate").

I revisited the scripts of pathalongpath, scatter, and interpolate, and updated them to use the z-order.
As a bonus, interpolate now also supports objects like groups, clones, stars...
