The way it works under X is that you ask the window manager what size
icon it wants to have, then provide that. Unfortunately GTK doesn't
export the functions you need to do this. It would be a nice addition
to 1.4 (in my opinion) if someone wrote code to let you do it
properly, maybe using GdkPixbuf.

KDE adds special window manager hints for setting a "mini icon" to go
in the window titlebar, and then hints are in the process of being
standardized with GNOME.

The X server holds a reference to the server-side object, so GDK
doesn't bother to keep a client-side reference.

In any case it shouldn't matter to you - if you're going to use the
pixmap again _you_ must hold a reference, even if you think someone
else already does. Them's the rules in a refcounted world.

Yeah that sounds like a bug, you might submit to bugs.gnome.org so it
doesn't get forgotten.
