Added a new attribute to vertices of a MeshBase object: the vec3 'inflate' vector.
This vector describes the direction where the vertex needs to be moved when we 'inflate' the whole mesh.
If the mesh is locally smooth, this is simply the normal vector; otherwise (for example in the corners of the MeshCubes) - not.
Currently the new attribute is always set to (1,0,0) and not used yet.
