        Implement CSS3 resize property

        * css/html4.css: Sets resize:both for textareas. This won't affect old-style textareas.

        * css/cssparser.cpp: (WebCore::CSSParser::parseValue): Added case for CSS_PROP_RESIZE.
        * css/cssstyleselector.cpp: (WebCore::CSSStyleSelector::applyProperty): ditto.
        * css/CSSComputedStyleDeclaration.cpp: (WebCore::CSSComputedStyleDeclaration::getPropertyCSSValue): ditto.

        * rendering/render_style.cpp: (WebCore::StyleCSS3InheritedData): Initialize resize.
        * rendering/render_style.h:
        (WebCore::): Added EResize enum.
        (WebCore::RenderStyle::resize):

        (WebCore::RenderStyle::initialResize):

        * page/FrameView.cpp:
        (WebCore::FrameViewPrivate::FrameViewPrivate): Added m_resizeLayer to keep track of a layer that has begun resizing.
        (WebCore::FrameViewPrivate::reset): Reset m_resizeLayer.
        (WebCore::FrameView::handleMousePressEvent): If the mouse was pressed in a layer's resize control, then put the layer into resize mode.
        (WebCore::selectCursor): Updated so we get a pointer cursor for the resize control.
        (WebCore::FrameView::handleMouseMoveEvent): If there's a layer currently resizing, then tell the layer to continue resizing.
        (WebCore::FrameView::handleMouseReleaseEvent): If there's a layer currently resizing, then pull it out of resize mode.

        * rendering/RenderBlock.cpp: (WebCore::RenderBlock::isPointInScrollbar): Updated so the resize control isn't considered part of the scrollbar.

        (WebCore::RenderLayer::RenderLayer): Initialize m_inResizeMode
        (WebCore::RenderLayer::updateLayerPositions): Calls positionResizeControl.

        * platform/mac/ImageMac.mm: (WebCore::Image::loadResource): Moved code from WebImageRendererFactory.  Now loads images from WebCore's resources.
        WebImageRendererFactory is no longer used and should be removed.
