I realized there actually are ways (of course!) to make an SVG having
no intrinsic dimensions but still scale to the destination: percentage
based lengths. It's now (2) at:


Firefox especially shows the difference between (2) and (3). In (2)
there is no intrinsic ratio, so the image is just scaled to the
destination. In (3) there is and it leaves blank space instead. Can't
say I think the result is any good though.

Now, I'm leaning towards actually doing what the spec says and divide
the border image area with slices and all and just assume the SVG can
handle it. Because there is a possibility it may. Thoughts?
