workspace: Use set_origin/set_size instead of properties when allocating

Browse Source 
Setting four properties is more expensive than calling two C functions,
so move to set_origin()/set_size() calls for our ClutterActorBox
handling.

This gets us down to an average time of 2.1 ms spent in vfunc_allocate()
with 20 windows
