- Add: GLProfile.get(name) return default if name=="GL" as well (or if null)

- Add: NEWT pumpMessages/dispatchMessages
    - Handled by the Display implementation for all windows
        - Windows .. OK
        - MacOSX .. OK
        - X11 .. OK 
            - Added Atom Property handling to attach java window object to window

    - Removed the eventMask for dispatching messages,
      since dispatching is for all windows now.
      (Wasn't impl. for all platforms anyways)

    - All init static code will funnel in the Display.initSingletion(), 
      to ensure a proper init order for all platforms.

    - Display creation is unique for (name,thread).
      Handling a TLS mapping of display-names to Displays.

    - GLWindow: autoSwapBufferMode and eventHandlerMode are static members

    - Tested with experimental tagged 
        GLWindow.setRunPumpMessages()/runCurrentThreadPumpMessage(),
      1 thread - 4 windows, etc ..
        java demos.es2.RedSquare -1thread -onepump -GL2 -GL2 -GL2 -GL2
      No benefit ..

      However .. the implementation is more correct now,
      due to the display/current-thread message pumping.

- Fix: Window.sendMouseEvent() bounds check

- Fix: MacWindow has proper nsView locking now,
  local to the window instance. locked in lockSurface 
  besides general window manipulation.

- Fix: JAWT utilized JAWTUtil.init() to 
       init libraries - NativeLibLoaderBase.loadNativeWindow("awt") 
       call was missing. (Visible on MacOSX + AWT)

- Fix: GLXUtil proper locking

- Fix: X11Util proper locking
