clutter/clone: Use graphene APIs

Browse Source 
This is another instance of graphene reversing the order of operations (see
the commit notes of how ClutterActor was ported.) The tl;dr; here is that,
in the CoglMatrix past, we used to do:

  (actor transforms) → scale

and now, it's the other way round:

  scale → (actor transforms)

due to changing from right-handed multiplications (CoglMatrix) to left-handed
ones (graphene_matrix_t).
