The OSD couldn't be updated at all without frame stepping. This made the VO unusable (In fact, vo_x11 should never be used, but it's provided as fail-safe fallback). Implement VOCTRL_REDRAW_FRAME to deal with this. Unfortunately, this exposes issues with draw_bmp's subtitle rendering: areas that are not covered by subtitles at all are changed as well. The "backup" mechanism provided by draw_bmp doesn't copy these areas, which turns up as quite visible artifacts. (These are included when taking screenshots too.)
