I couldn't care less about background images (my browser config
explicitly disrergards background settings), but image scrolling is
important and deserves its own TODO entry.

It seems more energy is spent on this list talking about such a thing
than doing it.  I sadly have no experience with such things at all,
so I wouldn't even know what to look for.

XEmacs allows something very similar, where a glyph can be any widget from
the underlying toolkit (that's how they added progress-meters).

What exactly is Richard unhappy about ?  I thought it was the fact
that it allows dynamic linking with non-GPL libraries, right ?
If so, what can we do (apart from trying to convince Richard otherwise) ?

Grepping emacs-devel for dump or pdump or portable dump or something
like that should get you to an article posted by a guy who said he
was working on exactly that.  Haven't heard much more about it, tho.

I generally agree with the rest, of course.
Please add it to etc/TODO.
