          Incomplete repaint when text-shadow is used in a render layer with explicit height

        Test: fast/repaint/layer-full-repaint.html

        Removed custom repaint logic from RenderLayer. repaintAfterLayoutIfNeeded()
        knows how to do everything we need now. The only catch is that we cannot
        rely on its "do a full repaint if the object needs layout" behavior, since
        by the time we call it, the needs layout flag has been reset. The solution
        is to cache the need for a full repaint in the layer.

        * page/FrameView.cpp:
        (WebCore::FrameView::layout): Removed call to checkForRepaintOnResize().
        * rendering/RenderLayer.cpp:
        (WebCore::RenderLayer::checkForRepaintOnResize): Removed.
        (WebCore::RenderLayer::RenderLayer): Replaced the m_repaintOverflowOnResize
        flag with a m_needsFullRepaint flag, which indicates that the layer needs
        to do a full repaint in the next call to updateLayerPositions().
        (WebCore::RenderLayer::updateLayerPositions): Simplified the repaint logic.
        Either call repaintAfterLayoutIfNeeded() or do a full repaint, depending on
        m_needsFullRepaint.
        * rendering/RenderLayer.h:
        (WebCore::RenderLayer::setNeedsFullRepaint):
        * rendering/RenderObject.cpp:
        (WebCore::RenderObject::setNeedsLayout): Mark the layer for full repaint.
