* gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line):
	(gtk_text_layout_move_iter_to_next_line): fix these two for
	invisible text, lots of other stuff still hosed.

	* gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook):
	new function, replaces the get/set palette stuff. This function
	is intended for use by libgnomeui which should set the hook to a
	thing which sets the palette in GConf, and we need the
	GConf-to-xsettings proxy which will result in the change being
	propagated back to the GTK app.

	* gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning
	about unusable signals that it may be because the signal has
	parameters.

	* gtk/gtkwidget.c (gtk_widget_modify_style): always copy the
	style, otherwise gtkrc.c won't know to create a new GtkStyle for
	it.
	(gtk_widget_modify_color_component): call
	gtk_widget_modify_style() so the rc style will get copied.
	(gtk_widget_modify_font): ditto

	* gtk/gtkrc.c: make a couple variables static

	* gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide
	help button by default, since it does nothing

	* gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool
	around with UI

	* gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify
	so we can have tooltips

	* gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we
	can have tooltips

	* gdk/gdkimage.h: mark gdk_image_new_bitmap with
	GDK_ENABLE_BROKEN, because its memory behavior is completely
	hosed.

	* gtk/gtknotebook.c: remove key press handler, replace with
	binding set, add numeric keypad support

	* gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete

	* gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms

	* gtk/gtkentry.c (gtk_entry_class_init): accept GDK_KP_Delete in
	addition to plain Delete

	* gtk/gtktextview.c (gtk_text_view_key_press_event): accept
	GDK_KP_Enter in addition to GDK_Return

	* gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to
	activate on entry instead of key press
	(gtk_font_selection_on_clist_key_press): get
	rid of this signal handler, not needed with new font sel.

	* gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a
	no-longer-needed emit_stop_by_name(), just return TRUE

	* gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings
	cruft, this widget is no longer focusable.

	* gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c,
	gtk/gtkhscale.c: Get rid of trough_keys virtual function, add
	move_slider action signal, add binding set for vscale/hscale, in
	the process support numeric keypad

	* gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings;
	make GDK_Return and GDK_KP_Enter activate the entry via
	binding set, instead of hardcoded.
