    st: Apply css foreground color to text as a PangoAttribute
    
    Rely on the Pango renderer handling this properly, instead of tinting
    the full ClutterText in the color specified through css.
    
    Also set the caret color explicitly, since it used to be set as a side
    offect of clutter_text_set_color(), but no longer is.
    
    Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/850
