Subject: Fix On-/Offscreen and PBuffer.

Demos are working again:
    demos.jrefract.JRefract
        - X11, Win32, OSX

    -Dsun.java2d.opengl=true  demos.jrefract.JRefract
        - X11, Win32

    demos.readbuffer.Main [-GL2,-GL2ES1] -test 0 demos.es1.RedSquare
        - X11, Win32, OSX, EGL

    demos.readbuffer.Main [-GL2,-GL2ES1] -test [12] demos.es1.RedSquare
        - X11, Win32
        - OSX not, because of the missing feature of
          attaching a read surface.
        - EGL not, because the emulation I used didn't support
          attaching a read surface. Emulation bug .. probably ..

MacOSXWindowSystemInterface.m createContext():
    - Verify if passed surface handle _is_ a view,
      now it could be a pbuffer etc .. handle as well.

Cleanup GLDrawableImpl.setRealized(boolean realized)
    - Calls setRealizedImpl() (implementation) now,
      and only if new stated differs ..

    - setRealizedImpl() fixed for:
        MacOSXPbufferCGLDrawable:    recreate/destroy
        WindowsOffscreenWGLDrawable: recreate/destroy
        WindowsPbufferWGLDrawable:   no-recreate/destroy
        X11OffscreenGLXDrawable:     recreate/destroy
        X11PbufferGLXDrawable:       recreate/destroy

WindowsWGLContext:
    - wglMakeContextCurrent(): uses isFunctionAvailable ..
    - create():
        Uses WGL.MakeCurrent() and releases the created context,
        due to unavailable MakeContextCurrent extensions
        before updating the procaddress tables.
