New Interface 'OffscreenLayerOption', impl. by JAWTWindow (impl) and NewtCanvasAWT/GLCanvas (delegation) ; Fix GLCanvas OffscreenLayerSurface usage.

JAWTWindow.destroy():
- No more getGraphicsConfiguration().getScreen().getDevice().close() call,
  since the configuration (hence the device) is passed @ creation and owned by the caller.

New Interface 'OffscreenLayerOption', impl. by JAWTWindow (impl) and NewtCanvasAWT/GLCanvas (delegation)
- Abstract offscreenLayer option to be delegated by using classes
- Allow offscreen testing of GLCanvas as well (like NewtCanvasAWT)

Fix GLCanvas OffscreenLayerSurface usage
- common 'createDrawableAndContext()' for context and drawable instance creation

- addNotify() calls createDrawableAndContext() after super.addNotify() to be able
  to lock the surface (JAWTWindow) and hence to determine offscreen usage.

- reshape(...) issues recreation 'dispose(true)' in case of using an offscreen layer

- dispose() explicitly destroys the JAWTWindow

NewtCanvasAWT:
- explicitly close the device of the JAWTWindow (as GLCanvas does)
