OSX/CALayer Threading Part4: Stream all JAWT Root CALayer Operations on OSX Main-Thread

Previous code created, set and unset the root CALayer on the current thread,
which lead to a very delayed destruction of the root CALayer w/.
With Java7 this lead to a possible resource starvation in certain situations,
since Java7 uses an CAOpenGLLayer.

Similar w/  f354fb204d8973453c538dda78a2c82c87be61dc,
creation, set and unset is operated on main-thread.
