NEWT/Window: Cleanup Actions: Reparenting, Fullscreen and Decoration

  - don't assume size/pos change - hence don't set window's values, but wait for satisfaction

  - don't send resize events on our own, just rely on the event mechanism

  - fullscreen: don't wrap action around invisibility from Java, Win7 flashes otherwise.
    Clients who benefit from it (X11) impl. it natively.

  - fullscreen exit: validate pos/size in case of a child window, like reparenting.
    Otherwise the container might gets confused (eg. AWT).
