Hi,
drawImage specification tells:
When the source rectangle is outside the source image, the source rectangle must be clipped to the source image and the destination rectangle must be clipped in the same proportion.[1]
Right now, when that happens, we draw nothing.
Firefox gets it right (at least for HTMLImageElement; for HTMLCanvasElement, there are some strange artifacts)
