Bug 83935 – GtkEntry's default invisible char should be U+25CF

        Bug 83935 – GtkEntry's default invisible char should be U+25CF

        * gtk/gtkentry.c (find_invisible_char) (gtk_entry_init): Find a
        more suitable invisible char than '*' based on the used font.
        (gtk_entry_class_init) (gtk_entry_set_property)
        (gtk_entry_get_property): Add a "invisible-char-set" property.
        (gtk_entry_unset_invisible_char): New function, needed now that the
        default invisible char isn't fixed.
        * gtk/gtkentry.h:
        * gtk/gtk.symbols:
        * docs/reference/gtk/gtk-sections.txt: Add the new function.
