-----------
BGE patch: use the Blender convention to duplicate groups in the BGE so that
the objects will be created with the location and orientation as in Blender.
Note that the BGE handles scaling in a parent tree differently than Blender. To
avoid discrepencies between the 3D view and the BGE, use only isotropic scaling
on all your objects except the leaf objects (i.e. without children) that can
have anisotropic scaling
