The spec defines this, no?  It's cited in

What makes you think such a thing even exists?  Gecko doesn't create a 
bitmap for an <img> pointing to an SVG file until actually painting the 
image (just like for an inline <svg> element).

The SVG should be re-rasterized at the width and height of the rectangle 
on the canvas it's being drawn into, I should think.
