// Action "ungroup drawing object" is now splitted into three parts - see
// method <SwDoc::UnGroupSelection(..)>:
// - creation for <SwDrawFrmFmt> instances for the group members of the
//   selected group objects
// - intrinsic ungroup of the selected group objects
// - creation of <SwDrawContact> instances for the former group members and
//   connection to the Writer layout.
// Thus, two undo actions (instances of <SwUndo>) are needed:
// - Existing class <SwUndoDrawUnGroup> takes over the part for the formats.
// - New class <SwUndoDrawUnGroupConnectToLayout> takes over the part for
//   contact object.
