	* gtk/gtkstyle.c (gtk_default_draw_handle): Significantly reduced
	the number of calls to gdk_draw_point() (and thus to X) by
	clipping the points by hand.

	* gtk/gtkhandlebox.c (draw_textured_frame): Actually make use of
	the clip parameter.
	(gtk_handle_box_paint): Only paint the handle if the expose area
	intersects it.
