First stop absolute positioned overflow hidden elements
	from growing to accommodate their overflow.  (Actually
	absolute positioned elements should never grow to do this,
	but fixing it for non-overflow hidden elements is hard,
	so later.)

	Second fix the render layer code to not allow background/borders
	of the object with overflow: hidden from being clipped.  This
	involves an extra paint step where the object paints its
	background and borders prior to establishing the clip rect
	for the children.  (This will also be necessary for overflow:auto
	and overflow:scroll).
