    stylecontext: Don't use bg image in gtk_style_context_set_background()
    
    Old code tried to use the "background-image" proeprty for setting the
    default image background. While this used to work in the early days of
    GTK3, today it is grossly misleading as the backgronud image may be
    resized, repositioned and semi-translucent which causes very weird
    artifacts when rendering.
    
    So we use the background-color only instead.
