Change object/entity line type scale by layer name in nested blocks

Googles this lisp sometime back. Was by Tharwat & Kent Cooper.

Works well but I now need it to change those in nested blocks too.

Need help with the changes to include objects & entities inside nested blocks.

           ;; Layers, but they do honor linetypes and linetype scale) -- any other possibilities? Leaders

           ;; and Dimensions honor linetypes, but for some reason not linetype scale.]
