This way the xserver never paints the frame background, even if the client window is destroyed. This allows us to have clean destroy window animation. There is no problem with interactive resizing because applications are using the XSync protocol, so we're not painting unless the client has redrawn. https://bugzilla.gnome.org/show_bug.cgi?id=734054
