Magic Cube

1) Cube: convert it to the latest library. Main difference: objects are rendered better, individual cubits have rounded corners.
2) Examples: some adjustments to MeshJoin & Predeform
3) Library: fix a bug in main_vertex_shader's 'degree' function, which didn't work proprely in case of a vertex which was exactly at the center (i.e. vector PS was zero)

In library: allow a mixture of a deep and shallow copy of a Mesh ( mVertAttribs1 might be copied deeply or shallowly, mVertAttribs2 are always copied deeeply).
