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