Window
non-opqaue (transparent) across platforms and JREs.
This method is not guaranteed to succeed, and will fail silently if the given Window
cannot be made non-opaque.
This method is useful, for example, when creating a HUD style window that is
semi-transparent, and thus doesn't want the window background to be drawn.
