File Source/core/rendering/RenderImageResource.h (right):

Source/core/rendering/RenderImageResource.h:56: virtual PassRefPtr<Image>
image(int /* width */ = 0, int /* height */ = 0) const { return m_cachedImage ?
m_cachedImage->imageForRenderer(m_renderer) : Image::nullImage(); }
We should fix this constructor to take an IntSize at some point.
