Fix CALayer pos/size and animation.b01

- Fix CALayer animation:
  - All CALayer animations are set to nil via overriding 'actionForKey'

- Fix CALayer pos/size bug:

  - Fix root and sub CALayer position to 0/0 and size on the main-thread w/o blocking.

  - If the sub CALayer implements the Objective-C NativeWindow protocol NWDedicatedSize (e.g. JOGL's MyNSOpenGLLayer),
    the dedicated size is passed to the layer, which propagates it appropriately.

  - On OSX/Java7 our root CALayer's frame position and size gets corrupted by its NSView,
    hence we have created the NWDedicatedSize protocol.
