        * platform/graphics/BitmapImage.h: Use RetainPtr for m_nsImage and m_tiffRep
        * platform/graphics/mac/ImageMac.mm:
        (WebCore::BitmapImage::initPlatformData): No need to do anything now
        (WebCore::BitmapImage::invalidatePlatformData): Simplify
        (WebCore::BitmapImage::getTIFFRepresentation): Use RetainPtr to avoid leaks
        (WebCore::BitmapImage::getNSImage): Use RetainPtr to avoid leaks
