Log Message:
-----------
BGE bug #17450 fixed: When we have parented objects with no scale-applyed
objects the ray hit system doesn't work properly. Fix by separating rotation
and scaling in the parent inverse node to keep scaling correct down to the leaf
objects. Only isotropric scaling should be used, as always with the BGE.
