Set here the translation vector applied to each new plane.
By default, each copied plane has the same coordinates as the
original plane. This is expected when copying a plane or a list
of planes to a different layer. However, when each new plane is
in the same layer as the original plane (for a list of planes,
the
Local option in the
Layer menu), a small
shift helps to separate the new planes from the original ones.
All other properties are the same for copied and original
planes (only the identification numbers are different).
