        * gtk/gtkcalendar.c (gtk_calendar_main_button): When
        changing months when the user clicks on a prev-month
        or next-month day, focus and select the new day.
        Ignore double clicks on prev-month, next-month days.
        (Based on suggestions from Andras Salamon, #74173)

        * gtk/gtkcalendar.c: Implement the focused/unfocused
        selected color change.
