 \warning The transformation provided to the functions `Deform_mesh::rotate` and `Deform_mesh::translate` always applies on the original coordinates of the input graph.
 That is in an interactive deformation session, the user is responsible for composing the transformations given to `Deform_mesh::rotate` and `Deform_mesh::translate`.
 In particular, any vertex which is no longer inside the ROI will be assigned to its original position in `Deform_mesh::preprocess`.
-The original positions can be updated by calling `Deform_mesh::overwrite_original_positions`. This behavior is illustrated in the tutorial.
