	* gtk/gtkviewport.c (gtk_viewport_style_set): Fixes
	to drawing the background of the bin window
	so that clearing and redrawing of child
	widgets work properly.

	* gtk/gtkwidget.c (gtk_widget_idle_draw): Juggle around
	data so that if somebody triggers more redraw queuing
	from a expose_event handler, it doesn't confuse the
	heck out of GTK+. (But is highly liable to cause
	an infinite loop...)
