Both PNG and JPEG have had this forever.  (PNG's approach is crude, but
JPEG's is reasonable.)  However, there's no way to control it client-side;
without somehow knowing how many bytes to load for a certain amount of
detail, all you can do is load the whole thing (or make multiple requests,
which is obviously worse).   I've thought about this in the past, but it's
a hard thing to make practical use of.
