Argh. 1.5 has setIconImage on Frame, not Window.

It's not that it didn't exist, it just used to be on Frame. So when
I did all my 1.5 testing, I was working with a JFrame, and then at the
11th hour decided to make this function take as general a thing as
possible, so I merrily climbed up the tree in 1.6 & didn't notice that
change.
