	* src/effects.c (effects_draw_box_animation_timeout): use the
	delay exposes feature to avoid the scren dirt

	* src/ui.c (meta_image_window_set_position): use gtk_window_move()
	to set the position
	(meta_ui_push_delay_exposes):
	(meta_ui_pop_delay_exposes): feature to let us delay redraws until
	after we do server-grabbed draw-on-inferiors effects
