Sun Nov 17 13:45:08 2002  Manish Singh  <yosh@gimp.org>

        * gdk/Makefile.am: add -DGDK_DISABLE_DEPRECATED

        * gdk/gdk.c (gdk_exit): remove obsolete comment

        * gdk/gdk.h: declare gdk_input_add_full if GTK_COMPILATION for
        gtk_input_add_full

        * gdk/gdkcolor.c (gdk_color_white, gdk_color_black): use
        gdk_colormap_alloc_color instead of gdk_color_alloc

        * gdk/gdkcolor.h: declare gdk_colormap_change if GDK_COMPILATION for
        gdk_colors_store. Also, gdk_colors_{alloc,free} for
        gdk_rgb_try_colormap

        * gdk/gdkdrawable.h: declare gdk_draw_string if GTK_COMPILATION for
        gtk_default_draw_string. Also, gdk_draw_text and gdk_draw_text_wc
        if GDK_COMPILATION for the respective gdk_window_ and gdk_pixmap_
        functions.

        * gdk/gdkfont.c: #undef GDK_DISABLE_DEPRECATED, completely compat
        code here

        * gdk/gdkfont.h: allow the GdkFont structure and a few gdk_font_
        functions for compat code in GDK_COMPILATION and GTK_COMPILATION.

        * gdk/gdkrgb.c (gdk_rgb_cmap_fail, gdk_rgb_try_colormap): use
        gdk_colormap_free_colors instead of gdk_colors_free.

        * gdk/gdkrgb.c (gdk_draw_rgb_image_core): no need to set fg/bg
        for own_gc, unused.

        * gdk/gdkwindow.h: declare gdk_window_get_deskrelative_origin if
        GTK_COMPILATION for gtk_handle_box_button_changed.

        * gdk/x11/Makefile.am: add -DGDK_DISABLE_DEPRECATED, renmae
        -DINSIDE_GDK_X11 to -DGDK_COMPILATION

        * gdk/x11/gdkcolor-x11.c: remove duplicate doc string for
        gdk_colormap_alloc_colors.

        * gdk/x11/gdkfont-x11.c:  #undef GDK_DISABLE_DEPRECATED, completely
        compat code here

        * gdk/x11/gdkx.h: use GDK_COMPILATION instead of INSIDE_GDK_X11,
        allow a few gdk_x11_font_ functions if GDK_COMPILATION for compat
        code

        * gtk/Makefile.am: add -DGDK_DISABLE_DEPRECATED

        * gtk/gtkclist.c
        * gtk/gtkctree.c
        * gtk/gtkpixmap.c
        * gtk/gtkpreview.c
        * gtk/gtktext.c: #undef GDK_DISABLE_DEPRECATED, deprecated widget

        * gtk/gtkhandlebox.c (gtk_handle_box_motion): use
        gdk_window_set_geometry_hints instead of gdk_window_set_hints.

        * gtk/gtkmain.c (gtk_exit): call exit directly

        * gtktipsquery.c (gtk_tips_query_real_start_query)
        * gtk/gtktreeitem.c (gtk_tree_item_add_pixmaps): remove some
        deprecated GDK usage.
