Tim Janik ac68581f96 added rc-style argument GtkSpinButton::shadow_type. removed 
Sun Mar 18 01:15:30 2001  Tim Janik  <timj@gtk.org>

        * gtk/gtkspinbutton.[hc]: added rc-style argument
        GtkSpinButton::shadow_type.
        removed spin_button->shadow_type, gtk_spin_button_set_shadow_type()
        and ARG_SHADOW_TYPE as it doesn' make much sense to try to override
        rc-style settings.

        * gtk/gtkfixed.c: removed gtk_fixed_paint() (was unused).

        * gtk/gtkwidget.c: quark cleanups.

        * gtk/gtkrc.[hc]: added gtk_rc_scanner_new() to create an rc-file
        scanner with appropriate configuration, renamed GtkRcStyleClass.clone
        to create_rc_style() (we don't do cloning in standard OO sense).
        added per rc style properties.

        * gtk/gtkstyle.[hc]: added code to retrive pspec conformant rc-style
        property values and for caching those. some cleanups.

        * gtk/Makefile.am: -DG_DISABLE_CONST_RETURNS.

        * gtk/gtksettings.[hc]: new file for global rc-file properties
        (at least currently, should get extended to support X properties
        and other communication mechanisms).

        * gtk/gtkwidget.[hc]: added style property support:
        (gtk_widget_class_install_style_property_parser): install style
        property pspec with parser function for rc-file values other
        than LONG, DOUBLE or STRING.
        (gtk_widget_class_install_style_property): same as above without
        parser (parsers are going to be needed quite infrequently).
        (gtk_widget_style_get_property): retrive style property value.
        (gtk_widget_style_get_valist): same as above with varargs support,
        has NOCOPY semantics.
        (gtk_widget_style_get): wrapper around gtk_widget_style_get_valist().
