Yeah...  I probably don't understand document-navigation well enough to
know how messy this would be for the image document. My initial
objection was along the lines of: "but then the <img> src attribute
would change", but I suppose we already don't bother that when the image
hits a redirect or something like that. So this could be done transparently.

One potential source of weirdness would be with media fragments &
svgView() -- both of these are expressed with a "#" suffix on the URL (a
fragment identifier).  These could be provided by the host site, but
then changed (internally) by the image itself, with user-interaction.
This seems like a bug in the idea, though maybe it'd be a feature...

bz might have more concrete thoughts on this. bz: in a hypothetical
world where browsers send events into <img> (for things like hover
effects and event-triggered SMIL animation), can you think of any
problem with *also* allowing clickable links in the image-document that
point to anchors elsewhere within the image-document? (assuming we block
navigation to & loads of external content)
