-Improved: The mesh smoothing algorithms applied in the Triangulation class and
-MappingQGeneric have been changed from the old Laplace-style smoothing to a
-transfinite interpolation that linearly blends between the descriptions on the
-faces around a cell. The old transformation introduced boundary layers inside
-cells that prevented convergence rates to exceed 3.5 in the global L2 errors
-on typical settings, whereas all derivatives in the mapping from unit to real
-cell are bounded by the derivatives of the manifold description. This change
-also considerably improves mesh quality on settings where curved descriptions
-were only applied to the boundary rather than the whole volume.
