            Extend AffineTransform to mapQuad
            https://bugs.webkit.org/show_bug.cgi?id=35444
    
            This makes mapQuad available for AffineTransform. So that platforms
            can make use of it after the switch from TransformationMatrix to
            AffineTransform in GraphicsContext.
    
            * platform/graphics/transforms/AffineTransform.cpp:
            (WebCore::AffineTransform::mapRect): mapRect already did the calculation for mapQuad but gave back the
                                                 boundingBox of the resulting FloatQuad.
