Layers do not repaint their outline when invalidated.

To reproduce: open the attached test case, resize the window so that you can
scroll the square completely out of view. Scroll it out, then *slowly* scroll
it in (you can Option-drag a scroll bar to scroll at mouse speed). Note how the
leading edge of the green outline does not paint as it enters the view.

I noticed two problems in RenderLayer::paintLayer() -- the rect in the
PaintInfo passed for the outline phase is the clipRectToApply, which does not
include the outline; and the outlineRect calculated by calculateRects doesn't
seem to be of any help with painting the outline either.
