Bug 741 HiDPI: Refine Monitor/Screen [virtual] Viewport Definition / Add NEWT Support / Fix JAWT getPixelScale deadlock

- NativeWindow/Surface/NEWT API DOC: Define Coordinate System of Window and Screen

- OSXUtil: Add getPixelScale(..) via Screen index and 'windowOrView'

- JAWTWindow/JAWTUtil.getPixelScale(..): Use pre-fetched AWT GraphicsConfiguration to solve AWT-TreeLock (deadlock)

- [Virtual] Viewport of MonitorDevice and Screen:
  - Properly calculate and expose [virtual] viewport in window and pixel units
    - OSX Monitor viewports in pixel units are 'reconstructed'
  - Window/Viewport to Monitor selection shall be perfomed via window units (unique)

- OSX NEWT Window create/init (native): Use given size and coordinates even in fullscreen mode
  Don't override by quering NSScreen coordinates, trust given values.

- Fix test cases, i.e. usage of pixel- and window-units
