Subject: OSX/Java7/CALayer + JAWT: Partially Fix AWT/NEWT CALayer 'out of
 sight' bug, where our CALayer is moved out of the visible area

- same erroneous behavior for GLCanvas and NewtCanvasAWT

- sized-frame: Set framesize and validate() it

- sized-component: Set component preferred size and call frame.pack()

- added workaround 'OffscreenLayerSurface.layoutSurfaceLayer()' to fix CALayer size, which snaps for:

  - OK initial size before setVisible: sized-frame and sized-component

  - OK resize w/ sized-frame

  - OK manual frame resize

  - Invisible: w/ sized-component after setVisible()

++

- CALayer-Sublayer (GL) has additional retain/release when added/removed
  to be on safe side.
