RE: -webkit-image-set

A : is just a regular character, so it's an ordinary file with no need 
for server processing - which is important.

I couldn't decide between the two options (regular file, or query 
parameter). I've actually been thinking that maybe we should support both:

<IMG src="foo.png" dpi="70 80 100" dpi-div=".">

The dpi-div character searches the end of the string for the character, 
then replaces it. So the above would become: foo.dpi=80.png

If the char is not in the file, then it's appended:

<IMG src="foo.png" dpi="70 80 100" dpi-div=":"> becomes:


If the dpi-div char is a ? then it gets special processing - it becomes a 
url parameter. A ? is added to the end of the src if there is none. If 
there already is a ? then an & is added.

The default would be a .

Another option:

<IMG src="foo.png" dpi="70=foo_70.png 80=foo_80.png 100=foo_100.png">

Basically after each dpi number simply put the desired url. It's more 
flexible, but much more verbose, and also more error prone.

I don't like the highsrc, or 2x things, because they are too limiting, and 
have no provision for the future. (Are we going to have 3.5x at some
