Bug 1214 - NEWT MacOSX: Detect auto-resize of Window when it is larger than screen

- On OSX (similar to X11) a created window with size > screen
  will get resized to fit screen size implicitly.

- Fix detects insets, position and size after onscreen window creation.

- Patch also merges insets and size change java callback
