    From uau: vo gl generates bitmaps for EOSD content (libass subtitles) when
    DRAW_EOSD is called but actual drawing of both EOSD and OSD is done in
    draw_osd(). Since draw_osd() was called first it drew the EOSD content
    from the previous frame, so the subtitles were always one frame late.
    As a simple workaround update EOSD content first, then normal OSD.
    This makes vo gl work correctly and should have no effect on anything
    else.
