        REGRESSION: Animated GIF ignores frame intervals and loops infinitely

        No test possible.

        * platform/Image.cpp:
        (WebCore::Image::shouldAnimate): Don't check that there is more than one frame,
        maybe the rest just hasn't been loaded yet.
        (WebCore::Image::startAnimation): Move the frame count check here - there is no need
        to start animating before we get at least two frames.
