RE: Time to install the new icons

[Drew Adams]

    sink.ico has a bit of nostalgia value...why not keep "sink.ico" just
    for that reason?

Sure, why not? You never know, perhaps everyone will prefer it - let's not
forget the saga of Classic Coke.

I'd propose keeping all of the old icons - to serve as a kind of museum -
labeling them with the Emacs version when they were introduced. As Miles
points out, their space is negligible. We might want to put all of the old
icons in a subdirectory (or sibling directory).

The main icon directory should, IMO, have multiple, current icons that are
essentially the same, with different color schemes. At least on Windows,
it's easy for users to choose the one they prefer.
