Newt Window

    - Uses GLCapabilities for window creation
        - Note: This is implemented in the new KDWindow only, for now.
        - FIXME: Respect GLCapabilities for other implementations (X11, MacOS, Windows)

        visualID shall be determined by GLCapabilities,
        and set to 0 if not implemented.

    - New OpenKODE KDWindow
        - Compile native code at with 'ant -DuseKD=true'
        - Use KD in newt with the Java property set newt.ws.name=KD

    - API change:
        NewtFactory.createWindow() takes GLCapabilities insteast of a fake visualID
