\note If the the selection of the vertexes is not consistent with the face selection
the append could build faces referencing non existent vertices
so it is mandatory that the selection of the vertices reflects the loose selection
from edges and faces (e.g. if a face is selected all its vertices must be selected).
from edges and faces (e.g. if a face is selected then all its vertices must be selected).
\note Attributes. This function will copy only those attributes that are present in both meshes.
Two attributes in different meshes are considered the same iff they have the same
name and the same type. This may be deceiving because they could in fact have
different semantic, but this is up to the developer.
If the left mesh has attributes that are not in the right mesh, their values for the elements
of the right mesh will be uninitialized
