Thank you for your comment.
I don't how to recompute the destructive brush stroke yet. Or I might
misunderstanding the meaning of "destructive." I thought destructive
means "destroy image itself and cannot undo it nor redo it" unless we
manage the undo cache. So it can't be non-destructive unless we save
that cache forever.
But maybe it's better to check the source code of gegl-paint first.
