    libmythui: Fix fullscreen windowing with Compiz (and Gnome?)

    This is based on the patch from Lawrence Rust in ticket #9589 which
    notes that Compiz requires the window to be visible before we set its
    state.

    Testing across various Ubuntu desktops (with and without Compiz and
    composite enabled) and on OSX and windows suggests that it is safe just
    to show the window earlier in the initialisation process and avoid the
    ifdef.

    libmythui: Revert recent Compiz/fullscreen window fixes.

    Some multi-screen setups (TwinView) are still broken despite an
    attempted fix. I can't honestly see any combination of initialisation
    sequence that fixes both the Compiz issue and doesn't break Twinview
    setups, so reverting until someone can figure out a better way.

    Refs #9589
