"Maybe".
It would be pretty nontrivial in Gecko; last I looked it would be
pretty painful in WebKit too. Can't speak for other UAs.
Can it be pumped through what's essentially an iframe on a null origin?
I don't know enough about browser internals to help on this one.
Yes, loading an SVG image is a heavy call.
For 90% of the SVG content out there, it'd probably be faster to parse
and draw the SVG via Canvas and JS.
Still it's a hell of a lot nicer to load it via <img> tag.
I'd just assumed that <img src="pic.svg" /> was loaded off-thread /
async much like <img> calls.
There's nothing that gets carried from the document to the <img> other
than the width/height, which I believe is carried through.
Which is a good thing, of course.
