* - Window client-area excludes {@link #getInsets() insets}, i.e. window decoration.
* - Window origin is relative to it's parent window if exist, or the screen position (top-level).

* directly with one of its components, or provide and register an
* implementation of {@link NativeWindowFactory NativeWindowFactory}
