          make GraphicsContext more suitable for cross-platform use, step 2

        - Changed GraphicsContext to use NSGraphicsContext as little as possible.
        - Removed the printing flag from GraphicsContext.
        - Changed GraphicsContext to assume the NSGraphicsContext is always flipped,
          and got rid of parameters to pass the flipped boolean around.

        * WebCore.vcproj/WebCore/WebCore.vcproj: Add GraphicsTypes.h/cpp and remove
        CompositeOperator.h/cpp.
        * WebCore.xcodeproj/project.pbxproj: Ditto.

        * bridge/mac/FrameMac.mm: (WebCore::FrameMac::setDisplaysWithFocusAttributes):
        * bridge/mac/WebCoreFrameBridge.mm: (-[WebCoreFrameBridge drawRect:]):
        * html/CanvasPattern.cpp: (WebCore::patternCallback):
        * html/HTMLCanvasElement.cpp: (WebCore::HTMLCanvasElement::createDrawingContext):
        * kcanvas/device/quartz/KRenderingDeviceQuartz.mm:
        (WebCore::KRenderingDeviceContextQuartz::createGraphicsContext):
        * platform/mac/WidgetMac.mm: (WebCore::Widget::lockDrawingFocus):
        Update for changes to GraphicsContext constructor (no flipped or printing boolean).

        * html/CanvasRenderingContext2D.h: Added a Path to the context state. Changed the
        LineCap and LineJoin types to use the new ones in GraphicsTypes.h instead of defining
        types here in this class. Changed m_platformContextStrokeStyleIsPattern and
        m_platformContextFillStyleIsPattern to be named m_appliedStrokePattern and
        m_appliedFillPattern and moved them outside the __APPLE__ ifdefs. Removed the
        platformContext() function. Moved applyStrokePattern and applyFillPattern out of
        the __APPLE__ ifdef.

        * html/CanvasRenderingContext2D.cpp:
        (WebCore::CanvasRenderingContext2D::State::State): Moved the stroke pattern

        (WebCore::CanvasRenderingContext2D::setGlobalCompositeOperation): Ditto.
        (WebCore::CanvasRenderingContext2D::scale): Update since platformContext() function
        no longer exists.
        (WebCore::CanvasRenderingContext2D::rotate): Ditto.
        (WebCore::CanvasRenderingContext2D::translate): Ditto.
        (WebCore::CanvasRenderingContext2D::beginPath): Changed to use GraphicsContext instead
        of using CGContext directly.

        (WebCore::CanvasRenderingContext2D::stroke): Ditto.
        (WebCore::CanvasRenderingContext2D::clip): Changed to use the current path and use the
        GraphicsContext instead of using CGContext directly.

        of using CGContext directly.
        (WebCore::CanvasRenderingContext2D::fillRect): Update since platformContext() function

        (WebCore::CanvasRenderingContext2D::applyStrokePattern): Made a tiny bit of this function
        cross-platform. The bulk is still Mac-specific.
        (WebCore::CanvasRenderingContext2D::applyFillPattern): Ditto.

        * html/CanvasStyle.h: Changed to use GraphicsContext instead of CGContext. Now the
        platform-specific stuff is in the implementation, not the header.
        * html/CanvasStyle.cpp:
        (WebCore::CanvasStyle::applyStrokeColor): Moved the ifdefs inside the function, getting
        us one step closer to platform independence.

        * page/Frame.cpp:
        (WebCore::Frame::paint): Change to check printing flag on the document, rather than on
        the GraphicsContext, since there is no printing flag for GraphicsContext any more.
        (WebCore::Frame::adjustPageHeight): Update for change to GraphicsContext constructor.

        * platform/GraphicsContext.h: Define a type called PlatformGraphicsContext so the
        platform-specific getter and constructor don't have to be ifdef'd. Added clearRect,
        strokeRect, setLineWidth, setLineCap, setLineJoin, setMiterLimit, setAlpha, setCompositeOperation,
        and clip functions. Removed the isForPrinting parameter from createGraphicsContextPrivate.
        * platform/GraphicsContext.cpp:
        (WebCore::GraphicsContextPrivate::GraphicsContextPrivate): Removed isForPrinting.
        (WebCore::GraphicsContext::createGraphicsContextPrivate): Ditto.

        Ditto.

        takes an NSGraphicsContext. Removed the flipText and forPrinting parameters
        to the other constructor.
        (WebCore::GraphicsContext::savePlatformState): Removed NSGraphicsContext code.
        (WebCore::GraphicsContext::restorePlatformState): Ditto.
        (WebCore::GraphicsContext::drawRect): Updated assertion to more-precisely
        reflect the limitation of the current version of this function.
        (WebCore::GraphicsContext::setColorFromFillColor): Ditto.
        (WebCore::GraphicsContext::setColorFromPen): Ditto.
        (WebCore::GraphicsContext::drawLine): Updated assertion to more-precisely
        reflect the limitation of the current version of this function.

        * platform/GraphicsTypes.h: Added.

        * platform/Image.h: Changed include to GraphicsTypes.h from CompositeOperator.h.

        * platform/Path.h: Removed constructors that take a Rect and an array of points. Made
        the Path mutable. Changed the types for contains and boundingRect to be float-based
        instead of int-based. Changed translate to take a FloatSize instead of two integers.
        Added clear, moveTo, addLineTo, addQuadCurveTo, addBezierCurveTo, addArcTo, closeSubpath,
        addArc, addRect, addEllipse, and platformPath functions. Defined a PlatformPath type
        so we don't have to ifdef the header so much.
        * platform/cg/PathCG.cpp:
        (WebCore::Path::Path): Changed class to always have a mutable path.
        (WebCore::Path::operator=): Changed to make a mutable copy.

        (WebCore::Path::clear): Added.

        * platform/mac/ImageMac.mm:
        (WebCore::fillSolidColorInRect): Changed to take a GraphicsContext instead of
        a CGContext.
        (WebCore::Image::checkForSolidColor): Changed to use the new setCompositeOperation
        in GraphicsContex.
        (WebCore::Image::draw): Changed to use the new PDF image and fillSolidColorInRect
        function that take GraphicsContext instead of CGContext.
        (WebCore::Image::drawTiled): Ditto.

        * platform/mac/PDFDocumentImage.h: Made most functions private. Changed to
        use GraphicsContext and FloatRect instead of CGContext and NSRect. Also
