Summary0027457: Modeling - Raise exception if scaled transformation is used for shape location
DescriptionThe fact is that use of transformations with non-unit scale factor in shape locations (e.g. method TopoDS_Shape::Moved()) is not well supported in OCCT: in most cases (especially if underlying geometry is elementary) this will lead to invalid shape, and most algorithms will fail due to being not able to handle effect of scaling on parameterization. It is quite regular that users get confused by this possibility (see e.g. https://github.com/tpaviot/oce/issues/615 [^]).

To prevent confusion, we can raise exception when scaled transformation is used for shape (e.g. in TopLoc_Location).
