Since version 2.6, each entity has a 'transformation history matrix'.
'Transformation history' (entity property)
Each time a transformation is applied to an entity (e.g. after a registration procedure, with the Interactive Transformation Tool or the Apply Transformation tool), the corresponding transformation matrix is added to the transformation history (matrix). This way the user can determine the 'total' transformation that has been applied to the entity since it has been loaded or generated.
Moreover this matrix can be exported to a simple text file or copied in the clipboard.
Note: this history matrix is also saved when saving the entity as a BIN file (i.e. it will be restored when loaded later).
