Of course, it might cause a delay in first `Deform_mesh::deform()` call due to the extra preprocessing computations.
\note The ROI does not have to be a single connected component, however considering performance issues it is best to use an individual deformation object for each connected component of the ROI.
The main performance gain in such a case is related to the factorization process (i.e. `Deform_mesh::preprocess`).
During deformation (i.e. `Deform_mesh::deform`), if we assume that the fill-in produced by the factorization is negligible, and the cost of back-substitution is linearly
The main performance gain in such a case is related to the factorization process (i.e. `Deform_mesh::preprocess()`).
During deformation (i.e. `Deform_mesh::deform()`), if we assume that the fill-in produced by the factorization is negligible, and the cost of back-substitution is linearly
proportional to the number of non-zero elements in the system, then the decrease in performance should be negligible.

Hence, they are not cumulative (i.e. any call to `rotate`, `translate`, or `assign` overrides previous calls).
Note that changing target positions of handle vertices (via `translate`, `rotate`, and `assign`)
has no effect while `Deform_mesh::deform` is not called. If no transformation is defined for a group of handles,
the corresponding vertices stay at their last target positions after a call to `Deform_mesh::deform`.
