[mutter/wip/surface-content: 35/36] window-actor: Kill off needs_pixmap

    window-actor: Kill off needs_pixmap
    
    It's mostly equivalent to the case where we've already detached
    the pixmap, *except* for the x11_size_changed case. We can simply
    detach the pixmap at the time the window changes size, though.
