    prevent flickering when changing slides
    
    When the window background is left at WhitePixel (from initialization) and the
    user has set a dark background color in config.h, the window shortly displays
    the white default background when clearing after advancing to another slide.
    This was very disturbing and is fixed now by setting the default window
    background color to the bgcol chosen in config.h.
