If the goal is mainly to test the latest versions of popular browsers,
it's safe to assume that SVG is supported in <img>, because as far as
I know, the latest versions of all popular browsers support SVG in
<img> (Firefox gains support in 4.0, IE in 9.0, WebKit/Opera have had
support for a while).  If the goal is to also correctly test
hypothetical user-agents that might or might not exist, I don't see
why you can assume PNG support either, or anything else, since the
spec doesn't require it.  I don't know why it should be a goal to
correctly test old versions of popular browsers.  We necessarily
exclude some classes of conforming UAs from the tests already, like
those that don't support JavaScript, so why not here too?
