Sun Oct  4 22:47:22 CDT 1998 Shawn T. Amundson <amundson@gtk.org>

        * gtk/gtkcalendar.h:
          gtk/gtkcalendar.c: More changes:
          - The day with focus is now seperated from the day selected
          - The day with focus has the xor's line around it
          - The selected day is now standard selected style
          - The week names and week numbers are now also drawn
            with selected style
          - Space now selects the day which has focus
