mplayer: don't keep previous video frame with --force-window
When for example switching off the video stream, and --force-window is used, forcefully reconfigure the VO. This will reset the size, and will clear the window with black. Needed some effort, because you don't always want to clear the window on "discontinuity" points like going to a next file: this would introduce some flicker.
