Bug 742 HiDPI: [Core API Change] Distinguish window-units and pixel-units; Add HiDPI for AWT GLCanvas w/ OSX CALayer

Core API Change:

To support HiDPI thoroughly in JOGL (NativeWindow, JOGL, NEWT)
we need to separate window- and pixel units.

NativeWindow and NativeSurface now have distinguished
access methods for window units and pixel units.

  NativeWindow: Using window units
      - getWindowWidth()    * NEW Method *
      - getWindowHeight()   * NEW Method *
      - getX(), getY(), ...

  NativeSurface: Using pixel units
      - getWidth()  -> getSurfaceWidth()   * RENAMED *
      - getHeight() -> getSurfaceHeight()  * RENAMED *

  GLDrawable:  Using pixel units
      - getWidth()  -> getSurfaceWidth()   * RENAMED, aligned w/ NativeSurface *
      - getHeight() -> getSurfaceHeight()  * RENAMED, aligned w/ NativeSurface *

Above changes also removes API collision w/ other windowing TK,
e.g. AWT's getWidth()/getHeight() in GLCanvas
and the same method names in GLDrawable before this change.

Now preliminary 'working':
  - AWT GLCanvas
  - AWT GLJPanel

Tested manually on OSX w/ and w/o HiDPI Retina:
  java com.jogamp.opengl.test.junit.jogl.demos.es2.awt.TestGearsES2AWT -manual -noanim -time 1000000
  java com.jogamp.opengl.test.junit.jogl.demos.es2.awt.TestGearsES2GLJPanelAWT -manual -noanim -time 1000000

TODO:
  - NEWT
    - Change Window.setSize(..) to use pixel units ?
    - OSX HiDPI support

  - Testing ..

  - API refinement
