And here's an SVG testcase as requested on IRC. The PNG is inline in the SVG as
a 'data' URI, but I've also attached it here separately.

The PNG embedded in the testcase should show as a square; the left half of it
red, the right half blue. The 2x2 px PNG is scaled up by the SVG. What happens
is that most of the image is clipped away and you only see a thin red vertical
rectangle (the left side of the PNG) instead of a dual color square.
