        Reviewed by Darin.

        All tests pass.

        * page/FocusController.cpp:
        (WebCore::FocusController::setActive): Update control tints when the
        active state changes.
        * page/FrameView.cpp:
        (WebCore::FrameView::updateControlTints): On Windows, we have to ask
        ScrollView to paint so that the outermost scroll bars will paint. On
        Mac, the outermost scroll bars are taken care of by NSScroller.
        * platform/PopupMenu.h: Updated for ScrollBarClient changes.
        * platform/ScrollBar.h: Added a new ScrollBarClient method.
        * platform/win/PlatformScrollBarSafari.cpp:
        (WebCore::PlatformScrollbar::paint): Invalidate when updating control
        tints so that we can paint with the new tint later.
        (WebCore::PlatformScrollbar::paintButton): Pass the active state down
        to SafariTheme.
        (WebCore::PlatformScrollbar::paintTrack): Ditto.
        (WebCore::PlatformScrollbar::paintThumb): Ditto.
        * platform/win/ScrollViewWin.cpp:
        (WebCore::ScrollView::ScrollViewPrivate::isActive): Added.
        (WebCore::ScrollView::paint): Pass paint calls on down if we're
        updating control tints so the scroll bars can invalidate.

        (WebCore::RenderLayer::isActive): Added.
        * rendering/RenderLayer.h:
        * rendering/RenderListBox.cpp:
