	Provide information about how an adjustment change in a range
	widget happened. Add a "slider-moved" signal which reports how
	a user is interacting with the range, whether they are clicking
	on a stepper or the trough, or dragging the slider.  (#133263,
	Thomas Fitzsimmons)

	* gtk/gtkmarshalers.list: Add signal type BOOLEAN:ENUM,DOUBLE.
	* gtk/gtkrange.c (gtk_range_class_init): Add "change-value"
	signal.
	(gtk_range_internal_set_value): Rename to
	gtk_range_real_change_value.  Add GtkScrollType parameter.  Emit
	the change-value signal when the range's value changes.
	(update_slider_position, gtk_range_scroll_event, step_back,
	step_forward, page_back, page_forward, scroll_begin,
	scroll_end): Change gtk_range_internal_set_value to
	gtk_range_real_change_value.
	* gtk/gtkrange.h (struct _GtkRangeClass): Declare change_value
	function.
