Subject: GLDrawableFactory Cleanup (-> On- Offscreen and PBuffer)     - Base
 all PBuffer/Offscreen GLDrawable creators on       a prev. created
 'NativeWindow + SurfaceChangeable' instance.       Simplifies implementation
 path.

      This also removes the almost cyclic referencing of
          GLWindow -> OffscreenWindow
          GLWindow -> Drawable -> NullWindow -> OffscreenWindow
      Now it is just
          GLWindow -> OffscreenWindow
          GLWindow -> Drawable -> OffscreenWindow

    - createGLDrawable() shall be used for all types now,
      especially if you want to pass the offscreen NativeWindow
      and benefit from the surfaceChangedListener etc ..

    - Add public createOffscreenDrawable(..)

    - EGLDrawable:
        - Query surface only if not 0
        - [re]create surface only if needed,
          using 'ownEGL*' flag for destruction only.
