    styles: make selections translucent
    
    We can follow some other styles now like Adwaita with slightly transparent
    selections. If we keep the foreground transparent, GTK 4 will avoid the
    second glyph draw altogether so there is minimal performance impact so
    long as the GL renderer (or better) is used.
